Broad spectrum antiviral drugs


How not to catch ARVI and not get a complication from the flu? Such questions on the eve of the cold season worry everyone. Help protect against infection and recover without complications called antiviral drugs with a wide spectrum of action. What is this medicine? How do they act and can they actually become a barrier to viruses?

We do not need Panadol, if we drink Arbidol?

How antiviral drugs are classified

Mankind has always been looking for (and continues to look for) a tool that will stop the disease-causing viruses. The first drug that received special anti-viral status was thiosemicarbazone. He really had the appropriate activity, but he acted very narrowly - against tuberculosis. The discovery of endogenous interferon was an outstanding event in the field of antiviral drugs. This was the starting point for a wide range of antiviral drugs.

Today, pharmaceutical companies are trying to develop universal drugs that can defeat several viruses or bacteria. It is precisely this multifunctionality that antiviral drugs of a wide spectrum differ. Their purpose is to prevent sickness from contact with the patient, to promote faster recovery and to prevent the development of complications caused by infectious diseases.

Humanity continues to suffer from the flu and similar ills, because viruses are represented by a huge number of species and have incredible possibilities of transformation. Despite this, existing antiviral drugs can help protect against infectious diseases and help people (especially those with weakened immunity) to avoid the negative and dangerous effects of colds and flu.

How are antiviral drugs classified?

All antiviral drugs of a wide range are divided (according to the classification of M. D. Mashkovsky) into 2 large groups:

  • interferons. They contain ready-made interferon (it is synthesized from human or animal blood);
  • interferogens. Such drugs stimulate the production of interferon by the body itself, thereby achieving antiviral effect.

Mechanism of action of antiviral agents

The mechanism of action of antiviral drugs

The drugs inhibit the causative agent of infection. By the principle of action they can be divided into 2 types:

  • drugs that suppress the virus (destroy the viral protein);
  • drugs that cause the body to produce interferon. This substance reduces the susceptibility of cells to the influence of the virus.

Who needs to take anti-virus drugs and when?

Despite the fact that the TV "prescribes" such drugs to everyone, there is a list of indications for their use. Antiviral drugs should be taken in such patients:

anti-virus drugs must be used

  • with bronchial asthma;
  • with chronic lung diseases;
  • those who have a malignant neoplasm;
  • patients with disabilities in the organs of the CCC;
  • in the presence of chronic kidney disease;
  • persons who suffer from blood diseases;
  • elderly people;
  • women during pregnancy.

To summarize, we can conclude: such drugs are necessary for those who have chronic diseases and weakened immunity, that is, they risk complications after a common cold or flu.

  • Ingavirin. The latest domestic drug. Able to inhibit influenza virus, SARS, parainfluenza. Suppresses the reproduction of the virus and stimulates the production of interferon. In parallel, it produces an anti-inflammatory effect.
  • Viferon. It has an immunomodulatory effect. Contains interferon. He gained a good reputation as a treatment for ARVI and flu. Suitable for adults and young patients, not contraindicated in pregnancy.
  • Kagocel Effective at any stage of the disease. Actively induces the formation of interferon, which helps the body to resist infection. It is an effective preventive measure.

Intestinal flu (or rotavirus infection) is fraught with complications no less than normal. Therefore, to prevent it, spread spectrum antiviral drugs are also used. These include:

  • Arbidol. Popular medicine in pill form. Its main active ingredient is umifenovir. Helps to overcome the symptoms of the disease. It is an immunomodulatory agent;
  • Cycloferon. The drug that synthesizes interferon. The main component of the drug is meglumine acridone acetate. Not suitable for pregnant women and children up to 4 years. It is effective not only as a treatment and prevention of influenza and ARVI, but also as one of the components of the treatment of herpes infection;
  • Groprinosin. Its most active element is inosine pranobex. The drug produces a direct antiviral effect and acts indirectly (increases the production of interferon). Forbidden to pregnant.

Nobody wants to get sick. If a pharmacy sells a rescue from flu and infections, isn’t it better to buy more drugs and always stay healthy? In fact, everything is not so simple.

The final decision on whether to drink or not to drink such a drug should be left to the doctor.
