Ways to fight the virus

Let’s look at the main ways to combat viral infections. Sometimes homeopathic medicines are divided into a separate group, but the mechanism of their action is not well understood.


They are developed exclusively for preventive purposes. Under the influence of the vaccine, antibodies are produced even before infection. The flu vaccine cannot protect against other types of SARS. But the flu vaccine is far from a panacea, since its action is directed against a specific type of flu. New strains appear almost every year, so modification of vaccines is an objective necessity. Vaccine production is based on scientists ‘ predictions about which strain will trigger the epidemic.

The best antiviral drugs: TOP 30 rating 2021


The mechanism of action of this group of medications is that they strengthen the immune system. The body copes with viruses much faster. All Immunostimulants can be (rather conditionally) divided into the following groups::

  • synthetic ones;
  • peptides;
  • natural resources.

If the body is conditionally healthy, Immunostimulants help to overcome the disease quickly enough. However, for weakened individuals (children, the elderly, pregnant women), treatment with Immunostimulants will not be effective enough.


The difference between this group of drugs is that they do not contribute to the expenditure of existing protective factors, but to an increase in their number and concentration. This group includes drugs that are interferon inducers. But there is one important point. Own interferon is spent on fighting the infection quite quickly. Much more success can be achieved if you enter it from the outside.

The best antiviral drugs: TOP 30 rating 2021

Antiviral drugs

There are specific and non-specific antiviral agents. The first ones are aimed at combating a specific type of virus at the moment when it did not have time to get inside the cells. They are only effective against one strain. Non-specific tools are universal. They apply to all types of viruses. As a rule, they are used against SARS, influenza A and B, herpes and other infectious diseases.

Groups of antiviral drugs

The most effective antiviral agents, depending on the mechanism of their action, are classified into the following groups::

  • antiviral agents containing antihistamines and immunomodulators (Anaferon, Arbidol). They prevent pathogen replication and stimulate the production of their own interferon;
  • products containing interferon (Grippferon, Alfarone). It often happens that the native protein structure that destroys viruses is consumed too quickly. Interferon, which is supplied from the outside, helps to cope with the disease;
  • interferon inducers (Kagocel, Lavomax). These drugs activate processes that accelerate the synthesis of their own interferons;
  • neuraminidase inhibitors (Tamiflu, relenza). The peculiarity of these drugs is that they have a depressing effect on the protein of the virus itself, preventing its development and spread.

The best antiviral drugs: TOP 30 rating 2021

Use of antiviral drugs

One of the classification features for antiviral medications is the diseases they are intended to treat. Let’s look at the most common cases.

For flu, acute respiratory viral infections

Flu and SARS are the most common viral diseases. They are characterized by a high risk of infection and are transmitted by airborne droplets. Despite the fact that almost every person has had SARS or flu, stable immunity to them is not developed. Diagnosis, as a rule, does not cause difficulties due to the characteristic clinical signs.

The causative agents of SARS are picornaviruses, adenoviruses. The disease is manifested by a runny nose, cough, sneezing, General malaise. Vasoconstrictor drops in the nose, anti-inflammatory and antihistamines are used for treatment.

Unlike SARS, the flu is much more severe. It occurs with a strong cough, headache, fever. The disease is dangerous with the development of complications. Along with symptomatic treatment, antiviral drugs are prescribed to eliminate the manifestations of intoxication:

  • Tamiflu;
  • Relenza;
  • Amantadine, Remantadine (effective only for influenza A).

The best antiviral drugs: TOP 30 rating 2021

Somewhat less effective is the use of Oxoline ointment, Interferon (nasal drops). A certain effect can be achieved by using vitamin C (ascorbic acid).


The coronavirus family includes 40 varieties of viruses containing RNA as of the beginning of 2021. It, in turn, is divided into 2 subfamilies that cause diseases in animals and humans. The name “coronavirus” is derived from the structure of the pathogens. The spiked appendages look like a crown. It is with its help that microorganisms are introduced into the host cells. There are several transmission mechanisms:

  • air-dust filter;
  • contact number;
  • air-drop mode.

The best antiviral drugs: TOP 30 rating 2021

Coronavirus infection manifests itself in the form of respiratory diseases, SARS, gastroenteritis and bronchitis. It is supposed to treat the new coronavirus of Chinese origin with such drugs:

  • Ribavirin;
  • Ritonavir (Lopinavir);
  • Recombinant interferon beta Ib

Herpes virus infection and herpes zoster

The family of herpes viruses is one of the most numerous known to date. They contain DNA and are relatively large in size. There are 8 types of herpes, each of which causes a specific disease. Another feature is the preservation in the body for a long time without any clinical manifestations. Therefore, the vast majority of the world’s population is healthy carriers of the virus.

The most common disease in this category is herpes simplex. For local treatment, use:

  • Penciclovir;
  • Tromantadine;
  • Acyclovir.

The best antiviral drugs: TOP 30 rating 2021

Drugs for systemic treatment:

  • Famciclovir;
  • Penciclovir;
  • Acyclovir.

Acyclovir and its derivatives block the synthesis of the DNA virus. The same drugs are also used in the treatment of shingles.

Viral hepatitis (B, C)

These are viral diseases that affect the liver. One of the most dangerous complications of the disease is cirrhosis, as well as liver neoplasms. Viral hepatitis is transmitted through skin lesions, sexual contact, and blood. Until 2011, interferons and Ribavirin were the mainstays of treatment. Today, more modern and effective means are used that minimize possible side effects:

  • Entecavir;
  • Dasabuvir;
  • Sofosbuvir;
  • Tenofovir and others.

The best antiviral drugs: TOP 30 rating 2021

Treatment of viral hepatitis is a long and expensive process. Today vaccines have been developed against hepatitis B. For group C vaccine yet.

HIV infection

HIV is a disease that affects immune cells. Thus, the body becomes defenseless against infections and tumors. On average, life expectancy after infection is 10 years, but specific antiretroviral therapy gives a chance to live much longer, up to 70-80 years. Treatment involves taking medication daily, at the same time. The most common drugs used for HIV infection:

  • Didanosine;
  • Lamivudine;
  • Zidovudine;
  • Indinavir.

The best antiviral drugs: TOP 30 rating 2021

Mechanism of action

The” physics ” of viral infection is something like this. When pathogens enter the body, they are embedded in the cell, causing its nucleus to produce the same particles. After their concentration becomes critical, they leave the cell.

Antiviral drugs can be classified according to their mechanism of action, among other things. Different medications affect different stages of the cycle:

  • prevent the penetration of pathogens into the host cell;
  • they destroy the viruses themselves before they penetrate the cell membrane;
  • block the replication of pathogens or their exit from the affected cells.

The best antiviral drugs: TOP 30 rating 2021

In addition to medications, there is another way to fight the infection. These are special proteins in the human body — interferons. To enhance this protection, there is a group of devices called interferon inducers. They strengthen the immune system by stimulating the production of interferon, thereby helping to defeat the virus.

How to tell a cold from the flu

Often in everyday life, the flu is called a cold, and Vice versa. In fact, this is fundamentally wrong. Influenza is a serious infectious disease that requires specific treatment. As for the common cold, such a disease can hardly be found in any classifier. Rather, it is a condition associated with hypothermia of the body. The difference between a cold and flu is shown in the table below.

Signs Flu Acute respiratory viral infections

Prevention of influenza and acute respiratory viral infections

All measures for the prevention of acute respiratory viral infections, influenza, and other viral infections can be specific or non-specific. The first group of measures is aimed at preventing infection with viruses of these diseases. The peculiarity of non-specific prevention is that it includes measures to prevent respiratory diseases, not necessarily of a viral nature. The main methods of prevention include:

  • the administration of specific drugs: immunomodulators or antiviral;
  • getting vaccinated;
  • balanced nutrition;
  • wearing special masks in public places. This is especially true for the period of epidemics. If possible, avoid places with large crowds of people;
  • hardening of the body.

One of the main preventive measures is immunization (vaccination). In this case, a particle of an infectious agent is introduced into the body. The virus contained in the vaccine contributes to the increased production of antibodies. The latter prevent the spread of infection and its penetration into the cells. Thus, it is possible to prevent the disease even before it begins. The optimal time for vaccination is autumn, since the peak of flu epidemics occurs between November and March. However, the high antibody titer decreases approximately six months after vaccination. Therefore, it makes no sense to get vaccinated too early.

Vaccination is not a guarantee against the disease. The reason is that viruses can mutate and adapt very quickly. There is a misconception that it is pointless to get vaccinated after the outbreak of the epidemic. In fact, even a late vaccination can protect against infection. Vaccination will be ineffective only if the person is already infected.

Medications to help you feel better-symptomatic treatment of a runny nose, cough

To alleviate the symptoms that often accompany viral infections (cough, runny nose), you can use medications aimed at comprehensive systematic treatment. These are instant drinks, such as “Gripp-out”, “TeraFlu” or “Coldrex”. This is only a small part of such funds. In fact, there are a lot of analogs. The main active ingredient is paracetamol. To enhance its effect, medicinal drinks contain:

  • phenylephrine– narrows blood vessels, used in the treatment of the common cold;
  • feniramin– has an anti-inflammatory effect;
  • ascorbic acid– strong natural antioxidant;
  • caffeine– has a General toning and stimulating effect.

With the help of these medications, you can improve your health for a short time. To influence a particular symptom, not complex drugs are used, but individual compounds. For example, children’s Panadol or Paracetamol in the “adult” dosage.

The General disadvantage of such drugs is that they eliminate (and then only briefly) the symptoms, and not the disease itself. Unpleasant sensations will return as soon as the effect of medications ends.

Copious drinking helps well as a symptomatic treatment. It can be tea with berries or lemon, compote, mors or herbal infusion. This is due to the fact that during the disease, the body is dehydrated due to increased sweating. In addition, drinking removes toxins and waste products of pathogens from the blood.

Do antiviral drugs exist or not?

Unfortunately, most of the antiviral drugs that are constantly flashing in television ads do not have the effect claimed by the manufacturers. It is often more profitable for manufacturers to invest in advertising than in conducting serious clinical trials.

In fact, medications that can affect infected cells do exist. Most of them are used in the hospital, intended for intravenous administration. The peculiarity of the drugs is that they are designed for a certain type of virus, and for no other. Drugs that have been shown to be effective in clinical trials include: Acyclovir (for herpes), Oseltamivir, Ribavirin (for influenza), and Adefovir (for retrovirus).

No one is immune from infection. But a person with a strong immune system will quickly cope with the infection, and a weakened one risks getting sick much longer. Therefore, along with taking special medications, a healthy lifestyle, proper nutrition and hardening are important.
