Antiviral drugs against influenza

Review of antiviral drugs in cases of influenza and influenza

Any disease, especially ARVI and the Flu is easier, cheaper and safer not to treat, but not to prevent, to prevent its occurrence. Recently, especially worried about the "point" - it's safer. Should I take antiviral pills at all? In today's complex world, how to understand the issues:

• Will the effect of using an expensive antiviral drug?
• Which drug is better for adults to take flu, children?
• Do not it cause harm to health?
• Is there the best cure for flu?
• Effective antiviral drugs - is it advertising, business, dummy or not?

Antiviral drugs for Orvy on the Russian pharmaceutical market are as follows:

Virtually all antiviral drugs for orvi and flu have no evidence base for their antiviral efficacy. Studies are very expensive, conducted by the manufacturers themselves and those interested in the positive conclusion of the parties. Today, most clinical trials of new drugs are regularly falsified in order to bring "miraculous" drugs to the market with a new price tag. Given the fabulous commercial benefits of selling expensive antiviral drugs during the epidemic, honesty and objectivity of research is not believed. As you know, pharmacological publications, even in medical journals today, are about 90 percent - these are custom-made articles of an advertising nature.

Today in the pharmacy chains an abundance of various medicines, some of which are essentially "medicines" They are not, because there are a lot of fakes, frank dummies and inefficient means. Advocates of patients' rights in Ukraine, for example, argue that in 4 drugs registered as antiviral - the active substance was not found. However, a wide advertising company allows producers to earn millions of hryvnias on them per year.

Antiviral drugs for Orvi are conventionally divided into:

• Vaccines - stimulation of the production of antibodies before infection with the virus
• Immunostimulants - drugs that temporarily enhance nonspecific immunity, which promote the production of interferons
• Antiviral drugs are agents that affect neuraminidase (a viral enzyme) by suppressing the multiplication of the virus (Oseltamivir, Zanamivir) and blockers M2-channels Amantadine, Remantadine - these drugs have proven clinical effectiveness, but as any means have a number of side effects.

Most antiviral drugs for orvi and influenza are developed and applied no more than 10-40 years. The drug should have a greater "trial period" in order to draw a conclusion about its effectiveness and side effects. As for immunostimulants, these funds can have delayed consequences (risks of autoimmune development diseases, oncological diseases of the blood, etc.) and should be prescribed according to strict indications.

Immunity modulators and antiviral agents

The immunostimulants produced today show the activation of immune reactions at the biochemical level (which is called "in test tube "), but their real benefit and long-term consequences of use are rather complex, poorly studied areas. Since information on many mechanisms of immunity has become known relatively recently, scientists are getting more and more information about its functioning every year. Therefore, there is no confidence in the safety and correctness of general stimulation of the "under-researched" immune system (see Fig. what is immunity and whether drugs are needed to improve it). Especially prudent should be the preventive use of immunostimulants and the treatment with antiviral medicines for children.

"Pharmacy immunostimulants can not only help the body, but also harm" - says Ph.D. Tatyana Tikhomirova, immunologist-allergist. Such a state as hyperactivation of the immune system, as well as immunodeficiency is extremely dangerous, the human body functions normally only with the balance of the immune system. And if a person each time stimulates ("to increase his own immunity"), then, in the presence of predisposing factors, this can result in pathological inflammation, immune aggression on healthy tissues, hyperactivation of the immune system and theoretically (in extreme cases) to the development of an autoimmune or oncological disease.

If the next of kin has an autoimmune disease (rheumatoid arthritis, insulin-dependent diabetes mellitus, Sjogren's syndrome, multiple sclerosis, etc.), then under no circumstances should a person use any immunostimulants. Even if a person is healthy, there is already a violation of the immune system, and you can live with them all your life, but if you are rude and persistently try to stimulate their immune system, this may end with the debut of an autoimmune disease.

Fortunately, for most healthy people, without the presence of any predisposing factors, it is difficult to "achieve" your immunity so as to seriously damage your health. Since most of the known immunostimulants either do not work at all, or almost do not work. One part of the drugs - an ordinary deception, another - ineffective means. But it should be remembered that any drug has side effects.

Drug Groups	Act	Names of drugs
Interferon preparations	Blockade of viral mRNA translation, presentation of viral antigens	Recombinant alpha / gamma interferons
Etiotropic means	Neuraminidase inhibitors	Relenza Tamiflu Peramivir
Ion channel blockers	Rimantadine (Remantadin, Orvirem)
Antiviral drugs with varying degrees of evidence of action	Enabling synthesis endogenous interferons	Kagocel Cycloferon Lavomax (Amiksin, Tyloron) Cytovir 3

NP-Protein Inhibitors	Ingavirin

Alexander Khadzhidis, Chief Clinical Pharmacologist, St. Petersburg states the following: "Some doctors for some reason first prescribe to patients antipyretic drugs, and then immunomodulators, allegedly for the production of interferon - which is illogical and generally absurd. That is, first, knocking down the temperature - "prohibit" the body to fight the virus (at high temperature antibodies are produced against the virus and infection), and then artificially "forced" to do so.

In developed countries, interferonogens (drugs that stimulate the production of interferon) are not at all. Interferons can work only with parenteral (intravenous) administration, and even then, their effectiveness is questionable. In Russia, these drugs are extremely popular, despite the fact that they are useless.

With regard to antipyretics with the virus - to knock down the temperature better with paracetamol and once with a rise in temperature, rather than 4 p / day - "just in case." Taking Aspirin (acetylsalicylic acid) in ARVI, especially in children under 12 years old, is contraindicated, it can cause severe lesion of the central nervous system and liver, it is not recommended to apply it to those who suffered from gastric ulcer. "

Well-known in Russia doctor Alexander Myasnikov says that all immunomodulators widely advertised in our country are a waste of money. In the United States and Western Europe, it is already unequivocally recognized and proven that these remedies are ineffective, but most Russian doctors continue to believe in the power of immunomodulators in treating Orvi.

Cytovir 3

Pharmacological action: Integratedimmunostimulating, an antiviral drug,

has an interferonogenic effect. As part of the drug - Timogen sodium, ascorbic acid, bendazole. Timogen synthetically obtained dipeptide, it enhances the nonspecific resistance of the organism. Ascorbic acid normalizes the permeability of capillaries, reducing the activity of the inflammatory process. Bendazol stimulates the production of endogenous interferon in the body.

Side effects: in people suffering from vegetative-vascular dystonia, causes a decrease in blood pressure.

Contraindications: in pregnancy, children under 1 year, thrombophlebitis, severe hypotension, diabetes mellitus, stomach ulcer, urolithiasis.

Issued: since 2001 in capsules, for children since 2006 in syrup, in powder for the preparation of solution
Research: There is no reliable information about clinical trials confirming its efficacy and safety. Often, doctors and pharmacists recommend this tool for children, but use it to treat children should be used with caution or not used at all.

References: Quite a lot of reviews in patients who use Citovir, about the effectiveness and absence of side effects. Improvement of well-being is observed on the second-third day, in single cases the drug did not help.
Price: Cytovir 3 - average240-580rub.

Kagocel

Pharmacological action: inducer of interferon synthesis, antiviral,immunomodulatingeffect. Composition: the sodium salt of the copolymer, which causes the formation of late interferon, which has high antiviral activity. The greatest effect occurs if you start treatment within the first 24 hours of the disease, but not later than the 4th day after the onset of an acute infection. With a view to prevention, it is possible to take it at any time, preferably immediately after contact with a sick Orvy or a flu.

Side effects: the emergence of allergic reactions.
Issued: Registered in 2003, since 2005 is produced in tablets, since 2011 allowed for use children over the age of 3 years for the treatment of influenza, as the prevention of children can be used for children over 6 years.

Research efficiency and safety: There is conflicting information. The active ingredient is the sodium salt of the gossypol copolymer with carboxymethyl cellulose.

And Gossipol itself is a natural polyphenol, it has been banned in the world since 1998 due to its toxicity. Gossypol for a long time and actively studied by some countries as a contraceptive, with its continued intake completely stops spermatogenesis. Chinese and Brazilian scientists say that host gossypol boys and men may suffer infertility in the future. However, Kagocel is not pure gossypol, it is the sodium salt of the copolymer, which has other properties that differ from the properties of the chemical itself.

The manufacturer actively advertises the drug and claims that the salt in Kagocel is negligible, 4 times lower than the concentration from the international standards allowed. Multiple stages of purification of the product ensure the absence of free Gossypol in the final drug, which is checked by monitoring the quality of each series of Kagocel tablets. The method used to check the availability of free gossypol is very accurate, it can reveal its content above 0.0036%. In early 2013, data were published on tests performed on rats - no changes in reproductive function were detected in animals.

That is, research on primates was not done? It is known that gossypol for different animal species has its maximum dose of toxicity, according to the EFSA (European Food Safety Authority) for rats, the limiting toxic dose is2200-3300 mg / kg.,for pigs 550, for guinea pigs up to 300 mg / kg. The research carried out by the manufacturer consisted in the administration of therapeutic doses to male rats, and doses 25 times higher than therapeutic doses250 mg / kg). Can you trust the rest of the statements and "studies"?

Neither in Western Europe nor in the United States Kagocel is not used, there are no WHO medicines on the list. The effectiveness of the drug is not proven according to the representatives of the Formulary Committee of the RAMS and SDMX. There were no statistical studies on the development of side effects as of autumn 2013.

The drug is actively recommended for adults and children, but evidence of the safety of this drug for children 3-6 years of age, no, there have been no clinical studies for this age group.

Reviews: Many help, some children and adults are allergic reactions in the form of rashes, swelling, itching.
Price: Kagocel - average180-280rub. In 2012, the volume of sales amounted to - 2.64 billion. rubles

Tyloron (Amiksin, Lavomax)

Pharmacological action: active ingredient Tiloron, possesses antiviral andimmunomodulatingaction, it is a synthetic inducer of interferon that stimulates the formation of interferons alpha, beta, gamma.

Side effects: short-term chills, allergic reactions, contraindicated in breastfeeding and pregnancy.

Issued: almost 40 years ago, children under 7 years of age are strictly prohibited.

Research: The benefits of the drug are unquestionable for both treatment and prevention of viral diseases, but this can overlap with potential harm to the body. In the 80's in the US, after tests on mice, the drug was banned, as it had a highly toxic effect,in experimental animals, retinal bundle, liver lipidosis and other side effects were observed. It does not apply in the US and the European Union. In our country, continue to produce antiviral Amiksin and doctors appoint it to patients.
A small study involved 14 patients who received tilorone in a dose of 152 and 189 g, in 2 drugs caused keratopathy and retinopathy (while visual acuity did not decrease), these effects were reversible. The authors of the study concluded about the potential danger of the drug for health.
Reviews: The occurrence of allergic reactions, the high cost of medicine.
Price: Amiksin - on average500-560rub. Sales volume in 2012 amounted to 1.17 billion. rub.

Additionally! Medicines, the so-called immunomodulators - Lycopid, Polyoxidonium, Cycloferon, Proteflazide, Timogen, Panavir, Isoprinosine, Neovir, Groprinosin and others. - should not be used to treat children (for various diseases) without an immunogram and serious indications, because they do not have the proper clinical trials of efficacy and safety in the treatment of children.

Antiviral drugs

Below are just some of the antiviral medications from Orvi, reviews about them, a brief description, comments on known studies of their effectiveness, the average price in pharmacies.

Ingavirin

Pharmacological action: active substance imidazolylethanamide pentandioic acid. It is active against adenovirus infection, influenza A, B, respiratory syncytial infection, parainfluenza. It is an immunomodulator that affects the functional activity of the interferon system.

Side effects: allergic reactions

Contraindicated: children under 18 years.

Produced: as a drug for the treatment of influenza and orgi from 2008, before that, according to prof. Vlasova Vasilia Vitaglutam (imidazolylethanamide pentanedioic acid) was used in Russia before 2008 year as a stimulant of hematopoiesis in cancer patients receiving anticancer therapy.

Research: According to the producers, the idea of ​​producing Ingavirin arose in the 1980s, but only After many years of research into its safety and efficacy, the drug was submitted for registration by 2008. When Vitaglutam was used in patients with oncological diseases, there was no convincing evidence of its effectiveness. And when in 2008 Ingavirin appeared on the pharmaceutical market without full-fledged studies, the "epidemic of swine flu" began in the country, therefore Ingavirin was actively sold. The drug was recommended by the Ministry of Health and Social Development, even despite the absence of placebo-controlled studies, reasonable evidence of its effectiveness.

One study conducted at 105!!! of patients with confirmed influenza showed the following results:

• Receiving ingavirin reduced the duration of fever to 34.5 hours (if used in the first 1-1.5 days from the onset of the disease)
• In the placebo group, this is 72 hours
• In the group taking Arbidol - 48 hours

Analyzing the duration and intensity of the symptoms of influenza - weakness, headache, dizziness in the studied groups with the ingestion of Ingavirin, the severity of the disease was confirmed, no side effects were revealed.

In May 2009, Alexander Chuchalin, chief therapist of the Russian Federation, (he led a team of drug developers) gave an interview to the magazine Ogonek: "The new antiviral agent Ingavirin efficiency is much higher than that of the AmericanTamiflu. The Russian drug is quickly and easily integrated into the genome of the A / H1N1 virus, immediately destroying it. It is also effective with other dangerous viruses. "

Reviews: Most drug does not help, isolated cases confirm the reduction in the timing of the disease.

Price:380-460rub. From January to June 2010, the sales volume of Ingavirin was 220 million. rubles, 467 thousand packages were sold.

Arbidol

Pharmacological action: Antiviral, has the ability to suppress viruses of influenza A and B, SARS - severe acute respiratory syndrome, associated coronavirus. Arbidol is also used in the complex therapy of acute rotavirus intestinal infections.
Active substance: Methylphenylthiomethyl-dimethylaminomethyl-hydroxybromoindole carboxylic acid ethyl ester.

Side effects: use of children under 3 years is prohibited, individual

allergic reactions.
Produced: invented in 1974, in 1992, it began its industrial production.

Research: Until 2013 there was no convincing evidence in its effectiveness and safety. Studies conducted in the USSR have not been published. In Russia in 2008, a study of 300 people showed that Viferon was more effective than Arbidol. In 2004, in China, tests for 230 patients with symptoms of Orvi showed it was not effective, in contrast to Tamiflu and Ingaverin. In 2009, in the journal of the UK "Antiviral Research", the authors of the research stated that strains resistant to Arbidol are formed less frequently than those of Remantadine and Amantadine.

The Office of Quality Control of US Medicines denied registration of Arbidol in the United States, and WHO has never considered this drug as an effective antiviral drug.

Update on the drug: At the end of 2013, the World Health Organization registered Arbidol (umifenovir) as an antiviral drug with direct action, assigning to it the individual code J05AX13. Thus, Pharmstandard received a nominal permission for widespread use of the drug on the territory of the Russian Federation, where Arbidol is included in the standards of treatment and prevention of influenza and ARVI in children and adults.

Nevertheless, the multicenter test of the effectiveness of Arbidol, which was planned to be completed in 2013, has not been completed to this day, and its terms have been postponed to 2015. The results of this trial, which has serious sponsors and does not suffer from a shortage of patients, could put a dot over I in the arbidol epic, but for unknown reasons this does not happen. I.eevidence of effectiveness is not present until now, it remains to wait ...

Reviews: The same number of positive reviews and opinions about the ineffectiveness of its use. There are isolated cases of allergic reactions in the form of dermatitis, angioedema, pain in the epigastric region.
Price: Arbidol - on average130-710rub. In 2012, the volume of sales - more than 5 billion. rub.

At the pharmaceutical market in Belarus, an analog of Arbidol, producer of JV "Lekpharm" appeared. It is a generic drug, in the Belarusian import-substituting packaging - Arpetol. The instructions to him indicate that the active substance is: arbidol hydrochloride? Once again, the commercialization of today's pharma market and the lack of proper control is proved!

Tamiflu

Pharmacological action: an antiviral drug, which includes oseltamivir carboxylate (active metabolite), suppresses influenza A and B viruses. When Orvi is not effective.

Side effects: Nausea, insomnia, diarrhea, dizziness, lethargy, cough, headaches, with caution to pregnant women and lactation. Contraindicated for children under 1 year.

Produced: since 1996, the pharmaceutical company "F. Hoffmann-La Roche "registered the right to develop

preparations containing oseltamivir.

Research: Tamiflu has a disadvantage - it complicates the diagnosis, because side effects are similar to the symptoms of influenza. It is dangerous in the epidemic period with long-term admission. Optimum effective only short-term use - a few days at the beginning of the flu. Independent researchers demanded a standard report from the Swiss manufacturer of 4-5 research modules. To which the pharmaceutical company provided only the first modules, repeated requests for full information were never satisfied.

Since 2004, cases of neuropsychic disorders began to be registered, more often in children and adolescents who took Tamiflu during influenza - hallucinations, nightmares, confusion, convulsions, anxiety, etc.

Japanese postmarketing studies of this drug in 2006 have indicated a risk of developing impaired consciousness in humans - psychosis, depression, suicidal tendencies, especially in children. Also, 54 deaths were recorded after Tamiflu, 16 of which were in adolescents 10-19 years (15 committed suicide, 1 died, hitting the car), the rest died of kidney failure (it is possible that due to severe flu).

The latest information about this drug:Back in April 2014, the Cochrane Society (an independent health research network) represented by the Tom Jefferson group and the British Medical Journal published data from the Cochrane review of studies that did not confirm the efficacy of Tamiflu and Relenza in the treatment and prevention of influenza. Also, the efficacy of reducing influenza complications with these drugs has also been questioned. The firm attempts of Roche firm to fight back with a firm promise to provide undeniable evidence in the form of results of randomized trials have so far not been successful. Evidence is expected to present.

April 10, 2014, the Cochrane Collaboration website published the results of these 26 clinical trials Relenza and 20 clinical trials of Tamiflu, in which 2, 00 people participated.

As a result of the research it was found that:

• Oseltamivir as a preventive agent slightly reduces the risk of developing influenza in families, without reducing the ability of the influenza virus to be transmitted from person to person.
• The duration of symptoms is reduced by 16 hours (from 7 to 6.3 days), in children this effect is absent altogether.
• The drug has no effect on the risk of serious complications (sinusitis, otitis media, pneumonia, bronchitis), that is, does not reduce the likelihood of complications.
• The medicine is recognized as sufficiently toxic, increasing the risk of nausea, vomiting in both children and adults.
• When used for preventive purposes, the drug was dangerous to health, as it leads to mental disorders, kidney function, in some cases it is established that it helps to reduce the production of their own antibodies to the virus.

Based on these studies, health officials of the world's leading countries should decide to stop mass purchases of antiviral drugs with the active substance Oseltamivir due to the high risk of side effects and low effectiveness as a medicine for the therapy and prevention of influenza virus in the epidemic.

reference: only on the basis of the claims of the manufacturer Tamiflu that the drug significantly reduces the risk of serious complications and hospitalization of patients in time of the epidemic, countries such as the United Kingdom and the United States in 2009, in connection with the epidemic of swine flu, these drugs were purchased for 40 million. doses (US $ 1.3 billion dollars, Great Britain 424 million. f.St.).

Based on the latest data on the low effectiveness and non-safety of this antiviral, the international expert group on evidence-based medicine urged the governments of the world's leading countries to stop the massive purchases of drugs Tamiflu and Relenza.

Reviews: There are enough reviews about side effects in the form of vomiting, dizziness, psychosis, headache. The effectiveness of influenza is confirmed by many.

Price: Tamiflu-on average1200-1300rub.

Remantadine (Rimantadine)

Pharmacological action: antiviral drug, an adamantane derivative, suppresses various strains of the influenza A virus (swine flu including).

Side effects: contraindicated in pregnant women, children under 1 year. Reduces concentration of attention, causes dizziness, nervousness, headache, increased fatigue, nausea, vomiting, dryness in

mouth.

Produced: information on the first uses of the drug are known since 1968.

Research: The tests were conducted from 1981 to 2006, mainly they showed a lower toxicity of Remantadine in comparison with Amantadine. One study showed the effectiveness of preventing Amantadine influenza infection by 61% in comparison with a placebo group and in the event that a person falls ill, then for 1 day reduced the febrile syndrome. In the same study, he was compared to Tamiflu, he gave an efficacy of 73% of the placebo group. Rimantadine (Remantadine) is currently considered a drug with proven clinical efficacy, but the possible resistance to it of some strains of the influenza virus.

Reviews: There are reviews that Remantadin causes side effects - dizziness, tachycardia, bitterness in the mouth. In general, the reviews are positive.
Price: Remantadine - average50-150rub.

It is during the flu (including swine) with the first symptoms of therapists and pediatricians recommend: adults - Remantadin, Tamiflu. Children over 1 year old are shown by Orvir (rimantadine syrup), Viferon. Children older than 8 years can - Remantadin (in the table), Tamiflu.

Interferon preparations

Interferons are informant proteins, which are excreted by cells infected with viruses. They seem to inform other cells about the infection and the required inactivation of the virus. Alpha interferons produce lymphocytes, beta - fibroblasts. In addition to Viferon, the alpha group includes Intron, Reaferon, Kipferon.

Viferon

The creation of the drug was scientifically justified in the period 1990-1995. group of scientists of the Research Institute of Epidemiology and Microbiology. N.F. Gamaleia under the guidance of prof. Malinovskaya V.V.
Since December 1996 on the basis of the same SRI, serial production of recombinant interferon alfa-2b in suppositories begins. Viferon - a candle with a different content of the active substance.

Application:

• Viferon-1 (150000 IU) is designed for babies from birth to 7 years. It is used in ARVI, herpetic infection, as an additional remedy for prolonged pneumonia or sepsis, including in preterm infants with intrauterine infections. The drug is given a course for 5 days. Children under 7 years are recommended 1 candle 2 times a day. Preterm, born on a period of more than 34 weeks - as children under 7 years. With a shorter gestation period - 1 candle three times a day. If necessary, after a five-day break, the course can be repeated for another 5 days.
• In children older than seven years, an adult drug in candles for 50, 00 IU is used twice a day for five days. Possible use of viferon in pregnant women.
• Candles with viferon content of , 0, 00 and , 0, 00 IU are used in the treatment of viral hepatitis and herpetic infections.
• The preparation in the form of ointment is intended for the therapy of herpes on the skin and mucous membranes in adults and children older than a year.

Side effects: the main side effect of drugs viferon may be an allergic reaction, which happens infrequently.

Research: As for the effectiveness of the drug, it is not included in list A of evidence-based pharmacology. I.e,wide randomized trials in humans consistent with international standards were not performed. However, a positive practical experience of treatment with viferon in pediatric practice is available. (By the way, nitroglycerin also does not have randomized studies that prove its effectiveness, which does not make it an ineffective first-line drug for stenocardia). Publications of these clinical trials of the drug are available only in Russian and were conducted only in domestic clinics. Value for money allows pediatricians to recommend a drug for ARVI treatment in children younger than seven years. For adults in the treatment of acute respiratory viral infections, the drug is of limited use because of rectal administration and the availability of alternative drugs.

The main arguments of the opponents of the drug:

• high molecular weight of protein molecules that can not be absorbed in the gut
• lack of clinical trials that meet international standards.

Kipferon

In candle light a little expensive for the treatment of common colds. Therefore, it is replaced by viferon. But, with severe forms of intestinal dysbiosis in children of the first two years of life, the drug shows good clinical results.

Studies: Randomized trials were not conducted, that is, the drugrefers to the list of drugs with unproven effects. The main claims:

• High molecular weight, which prevents normal absorption
• Adding to the drug components of the donor blood, which can cause fever and allergies.

Cycloferon

Cycloferon was originally registered as a veterinary drug in 1993 for the treatment of animals with viral infections, in 1995 it was already honey. a drug.

The drug Cycloferon is approved for use in adults and children older than four years. Produced in solution for injection, tablets, liniment. Refers to immunomodulating drugs, is an inducer of interferon, enhancing its production and exhibiting antiviral, anti-inflammatory and immunostimulating properties.

Application: on the territory of the Russian Federation it is used in the treatment of acute respiratory viral infections, influenza, viral hepatitis, herpes infection, viruses human papilloma and other urological and gynecological pathologies (eg, candidiasis, chlamydia).
Contraindications: The drug is not recommended for pregnant and lactating. May cause an allergic reaction.
Research: Cycloferon is an immunostimulant that stimulates the immune system and the production of interferons. To date, allclinical trialsthis drug, published in the medical literature,were conducted only in the territory of the Russian Federation and do not meet international standards.

According to tsikloferon there are no serious clinical trials that would prove its effectiveness or would be refuted absence of long-term adverse effects of this drug (development of autoimmune diseases). It is not superfluous to recall that all drugs that are on the pharma market for less than five years are still at the fifth level of pharmacological tests and it is quite possible to identify previously unknown undesirable effects from drugs of this kind. In the presence of newly identified harmful effects, the drug will be withdrawn from the pharmacy chains and discontinued, and the majority those who have been treated with this drug and have earned some disruptions in health are unlikely to receive at least some compensation.

Conclusions:

Ineffectiveness of antiviral agents due to the stability of strains of the virus

The lack of a positive effect with the use of some antiviral drugs for influenza is possible, and because of the appearance drug-resistant viruses and a specific influenza strain may already be resistant to a particular drug (eg, Remantadine).

Other treatments and placebo effect

It is also possible that patients whose reviews indicate the efficacy of such remedies were quickly recovered by other methods of symptomatic treatment, and the placebo effect is not excluded (cf. amazing facts about placebo).

Strong immunity

In a healthy organism, after 2-3 days, the immune system produces enough protective antibodies against the virus, it does not need additional medicines. It is enough to comply with all the known rules - bed rest, plentiful hot drink, vitaminized foods and drinks, clean air in the patient's room, gargling, etc.

Rapid recovery with antiviral drugs

In different life situations, reducing the duration of the disease even for one day can be very important, to example - wedding day, urgent business trip, important business deal, exam, interview, etc. It is in such cases that the use of antiviral drugs, which reduce the duration of the illness by 2-3 days, may make sense.

There are no adequate studies

The lack of benign research on the study of efficacy and side effects (on a large group of people, different ages, for a long time time), the majority of antiviral agents from Orvi and influenza suggest the caution of their use or even the rejection of them.

Do not spend money on pacifiers

Spending money, in some cases, considerable, on drugs with unproved efficacy, side effects, questionable safety, perhaps, is not advisable. Any medicine, even useless or empty, can damage the body.

List of inexpensive drugs against influenza and colds

Almost every person, at least once a year, suffers from a cold. No matter how strong the human body, it can not be fully insured against viruses and infections, especially if there is an off-season or winter. Producers for disease control offer inexpensive medicine for colds and flu. You need to know which ones are not just cheap, but also effective.

Antiviral drugs are inexpensive but effective

All funds for influenza and cold are divided into three broad categories:

1. Antiviral. These drugs fight the virus, make the body cells more resistant to its effects.
2. Immunomodulators. Preparations to correct the body's defense reactions to the natural level.

Reviews

Olya, 27 years old: At the first symptoms of the flu, I always take some symptomatic medicine, for example, "Rinzu" or "Coldrex". This does not allow the infection to "play out". Immunomodulators did not drink at all because of the high price. And I try to treat the child with folk remedies, but I knock down the temperature with Paracetamol. I trust more domestic products.

Lena, 35 years old: Now the pharmacy offers so many names of medicines for colds that it's hard not to get lost. I try to use antipyretic drugs, for example, "Aspirin" or "Paracetamol." If the runny nose begins, then I use "Pinosol". He helps well, though he does not break his nose. If you start a sore throat, I use "Chlorophyllipt".

Tanya, 24 years old: I always have ORVI with fever and cough. I drink Fervex in powders, and I also buy ACTS. Thanks to this treatment, my illness lasts for three or four days. Last winter, saw for the prevention of "Arbidol", but still sick, so I do not recognize any medications for correcting the immunity. I'm cured when the cold has already begun.

Antiviral drugs for colds

Antiviral drugs for colds - the main tool in the fight against this category of ailments.

As is known, during the period of activation of catarrhal diseases it is better to be engaged in their prevention, and not to bring them to conditions when treatment is already needed. Activating immunity in the cold season is the most effective measure to protect yourself against colds. Then the disease will not develop or, at least, the situation will not take on a serious form.

If the disease has a viral nature - acute respiratory viral disease (ARVI) - then there can not be no treatment without treatment. And it is best in this case to cope with the problem of antiviral drugs. The essence of their action is in the impact on the virus itself, which is an etiological factor.

Antiviral drugs are used to treat ARVI and influenza. These drugs affect the replication of the virus in such a way as to stop its reproduction. Antiviral drugs are synthetic or natural. They are used both in the fight against the disease, and for its prevention. Different stages of the common cold can be exposed to antiviral drugs. To date, modern science knows about five hundred pathogens of different kinds of colds. Antiviral drugs to fight them quite a bit.

In general, viral diseases are treated with three types of drugs:

• drugs for a wide spectrum of influenza;
• drugs for the treatment of herpes infections.
• means for controlling cytomegalovirus.

In the case of severe disease, antiviral drugs are taken, with the use of interferons is easy. Within a day and a half after the appearance of the first symptoms, it is urgent to begin taking an antiviral drug. If we allow the multiplication of the virus to such a scale that it will occupy the entire body, then it can be brought to the conclusion that taking medications will not have any effect.

Effects of antiviral drugs for colds

With the help of antiviral drugs, the causes of the onset and development of acute respiratory disease are eliminated. The results of this action are:

The essence of the action of M-channel blockers in the blocking of the virus so that it can not penetrate into cells and multiply. One of the tested preparations against viruses of this category is Amantadine (Midantan), and also Rimantadine (Remantadin). For the desired effect, they should be taken as soon as the disease begins to manifest itself. Another of their drawbacks is that it is not always possible to understand what kind of virus a person has become. And these antiviral drugs are shown in the epidemic from the influenza A virus. In addition, avian and swine flu are resistant to them. It is important to remember that taking an antiviral drug for a cold should be done not only by the sick person himself, but by all members of his family.

Effective antiviral agent for colds

But neuraminidase inhibitors act on influenza A and B viruses. The essence of their action in suppressing the enzyme, which is responsible for the multiplication of the virus.

Antiviral drugs for ARVI

Complexity in the development of antiviral drugs of a broad spectrum of action, namely antiviral drugs ARVI, lies in the significant variability of viruses, in their ability to form new resistant species. Even outer space will not be an obstacle for them.

What is a virus?

At its core, it is a non-cellular form of existence. It is able, with the help of its genome, to reproduce in the cells of a more highly organized life form. The genome of the virus is represented by DNA and RNA by acid chains. The virus uses the contents of the cell, where it penetrated, as a nutrient medium.

Fast synthesis of new viruses and cell death. Then, new cells are captured. The introduction into the cell can take place in a variety of ways, for example through air or water.

Each type of virus has a predisposition to the defeat of certain human tissues: the intestinal epithelium, liver cells, epithelium of the upper respiratory tract, etc. The human immune system is protected by the interaction of antibodies and interferon.

Antibodies remember the virus and destroy only the one against which they were synthesized. And interferons are special nonspecific proteins that block the virus inside the cell. They fight all pathogenic viruses, and also interrupt their division. At the same time they protect healthy neighboring cells.

But there are depressing synthesis of interferon picorn- and flaviviruses. Modern antiviral drugs should play the role of prevention and inhibit the development of viruses.

Types of drugs

There are several groups of antiviral medications:

• medications containing interferon and enhancing its synthesis;
• antiviral immunostimulants;
• homeopathic medicines;
• cytostatic drugs.

Homeopathic Remedies

So, let's see what kind of antiviral drug is better to use.

Homeopathic immunostimulants work better in the pre-infection period. To those we attribute:

• Viburkol;
• Aflubin;
• Oscillococcinum.

If after the first day of use there is no positive result from these medications, then they must be replaced or discontinued.

Chemical substances

Antiviral substances of this type include:

• Tamiflu;
• Arbidol;
• Remantadine;
• Ribavirin.

The most popular Remantadine is clinically active only in the first days of infection, and it affects only the influenza infection.

Here Ribavirin works for both influenza and respiratory syncytial viruses. This drug is more active than Remantadine.

Note that the possibilities of Arbidol are greatly exaggerated, because it acts only on the flu, and only during the precursors of the disease.

The most effective here is the antiviral drug of the new generation Tamiflu. It reduces the time of illness by 2 times. And also reduces the incidence of complications twofold. However, he also has shortcomings:

• not investigated on children;
• has a large number of contraindications.

The safest drugs

The most harmless group of antiviral drugs is the group of interferon and its derivatives. These drugs have very high activity. When taking these antiviral medications for ARVI, the symptoms of colds often go by 1-3 days.

The drug works in any period of the disease. Produce it in the form of injections:

• Laferon;
• Amiksin;
• Interferon;
• Neovir, etc.

Candles Kipferon and Viferon are used rectally. With a cold, drops in the nose Grippferon.

Kipferon contains specific antibodies and will act more quickly.

But Viferon causes the least amount of allergic reactions.

Note that the clinical effectiveness of all three interferon-containing drugs are the same between each other.

With complicated forms of ARVI, slow interferon inducers are not recommended, such as:

• Amiksin;
• Cycloferon;
• Neovir.

It is better to use Derinat. He quickly synthesizes alpha and beta interferons. Also combines the qualities of an immunostimulant.

Immunostimulants

The last group of drugs is used according to the doctor's prescription. These drugs are immunostimulants. To the list of these

antiviral drugs we will include:

• Isoprinosine;
• Bronhoimimumal;
• Imudon;
• Ribomunil.

It is better to use them for prevention and as a means of support. When choosing an antiviral drug for the treatment of acute respiratory viral infection, it is necessary to take into account both the phase of the disease and the data of laboratory diagnostics. It is also very important to consider the point of application of the drug, its possible complications and contraindications for use.
