Pharmacological properties
Pharmacodynamics
Antiviral agent. Specifically suppresses in vitro influenza viruses A and B (Influenza virus A, B), including highly pathogenic subtypes A(H1N1)pdm09 and A(H5N1), as well as other viruses that cause acute respiratory viral infections (ARVI) (coronavirus, associated with severe acute respiratory syndrome (SARS), rhinovirus (Rhinovirus), adenovirus (Adenovirus), respiratory syncytial virus (Pneumovirus) and parainfluenza virus (Paramyxovirus)). In in vitro studies, it specifically inhibits the SARS-CoV-2 virus, which causes novel coronavirus infection (COVID-19). The EC50 (half maximal effective concentration) in Vero E6 cells is 4.11 µM, which corresponds to 2.11 µg/ml. The clinical significance of this requires further study.
According to the mechanism of antiviral action, it belongs to fusion inhibitors, interacts with the hemagglutinin of the virus and prevents the fusion of the lipid membrane of the virus and cell membranes. It has a moderate immunomodulatory effect and increases the body's resistance to viral infections. It has interferon-inducing activity - in a study on mice, the induction of interferons was noted after 16 hours, and high titers of interferons remained in the blood up to 48 hours after administration. Stimulates cellular and humoral immune responses: increases the number of lymphocytes in the blood, especially T-cells (CD3), increases the number of T-helpers (CD4) without affecting the level of T-suppressors (CD8), normalizes the immunoregulatory index, stimulates the phagocytic function of macrophages and increases the number of natural killer (NK) cells.
Therapeutic effectiveness for viral infections is manifested in a decrease in the duration and severity of the disease and its main symptoms, as well as in a decrease in the incidence of complications associated with viral infection and exacerbations of chronic bacterial diseases.
When treating influenza or ARVI in adult patients, a clinical study showed that the effect of the drug in adult patients is most pronounced in the acute period of the disease and is manifested by a reduction in the time for resolution of symptoms of the disease, a decrease in the severity of the manifestations of the disease and a reduction in the time for elimination of the virus.
Therapy with the drug leads to a higher frequency of relief of symptoms of the disease on the third day of therapy compared to placebo - 60 hours after the start of therapy, the resolution of all symptoms of laboratory-confirmed influenza is more than 5 times higher than the same indicator in the placebo group.
A significant effect of the drug on the rate of elimination of the influenza virus was established, which, in particular, was manifested by a decrease in the frequency of detection of viral RNA on the 4th day.
Refers to low-toxic drugs (LD50 > 4 g/kg). Does not have any negative effects on the human body when administered orally in recommended doses.
Pharmacokinetics
Quickly absorbed and distributed throughout organs and tissues. The maximum concentration in blood plasma when taken at a dose of 50 mg is achieved after 1.2 hours, at a dose of 100 mg - after 1.5 hours. Metabolized in the liver. The half-life is on average 17-21 hours. About 40% is excreted unchanged, mainly with bile (38.9%) and in small amounts by the kidneys (0.12%). During the first day, 90% of the administered dose is eliminated.
Indications for use

Pharmacodynamic properties
The mechanism of reproduction of viruses is different from that of bacteria. Viral particles penetrate through the mucous membranes of the respiratory tract into the blood. The pathogen seeks to enter the host cell. This is necessary for the synthesis of new viral particles.
The microorganism penetrates the cell and uses the patient’s DNA to form the virion genome. New microbes enter the bloodstream and spread throughout the body. The cell that was used to create new virions dies.
Umifenovir, which is the active component of the drug, has an antiviral effect on the body. The substance prevents the viral particle from merging with the host cell. Because of this, the virus cannot penetrate into the cell.
The drug prevents the virus from multiplying. The pathogen is not able to continue its life cycle, therefore it is present in the circulatory system for a long time. The protective cells have time to recognize and destroy dangerous microorganisms.
The medication also enhances immune defense. While taking medication:
- The number of lymphocyte cells increases;
- The function of macrophages that capture harmful microbes is stimulated;
- The number of immune cells that detect the presence of foreign microorganisms increases.
When the drug Arbidol is used correctly, patients tolerate the disease more easily. The duration of the disease decreases. Symptoms: hyperthermia, muscle pain, nasal congestion, sore throat begins to subside already on the 3-4th day of therapy.
Arbidol Maximum caps 200 mg N10 (OTISI)
Antiviral agent. Specifically suppresses in vitro influenza viruses A and B (Influenzavirus A, B), including highly pathogenic subtypes A(H1N1)pdm09 and A(H5N1), as well as other viruses that cause acute respiratory viral infections (ARVI) (coronavirus associated with severe acute respiratory syndrome (SARS), rhinovirus (Rhinovirus), adenovirus (Adenovirus), respiratory syncytial virus (Pneumovirus) and parainfluenza virus (Paramyxovirus)).

Refers to low-toxic drugs (LD50 > 4 g/kg). Does not have any negative effects on the human body when administered orally in recommended doses.
Is it permissible during COVID-19?
Umifenovir is recommended for use both for the treatment of coronavirus infection and for the prevention of infection with Covid-19. As a preventive measure, the drug is ideal because it prevents the virus from entering cells, even if there has been contact with a sick person. Coronavirus can be present in the blood for up to 2 weeks or more without penetrating into cells. This explains the long incubation period (asymptomatic). For preventive purposes, it is recommended to take Arbidol for 2 weeks, which will prevent the virus from entering cells and its further reproduction.
It makes sense to prescribe the drug for the treatment of coronavirus infection, as it stops further reproduction of viruses. The medicine relieves symptoms and prevents complications. Arbidol copes well with mild forms of COVID-19.
Arbidol® (Arbidol®)
Antiviral agent. Specifically inhibits in vitro influenza viruses A and B {Influenzavirus A, B), including highly pathogenic subtypes A(H1N1)pdm09 and A(H5N1), as well as other viruses that cause acute respiratory viral infections (ARVI) (coronavirus {Coronavirus) associated with severe acute respiratory syndrome (SARS), rhinovirus (Rhinovirus), adenovirus (Adenovirus), respiratory syncytial virus (Pneumovirus) and parainfluenza virus (Paramyxovirus)).

Therapeutic effectiveness for viral infections is manifested in a decrease in the duration and severity of the disease and its main symptoms, as well as in a decrease in the incidence of complications associated with viral infection and exacerbations of chronic bacterial diseases.
In the treatment of influenza or ARVI in adult patients, a clinical study showed that the effect of the drug Arbidol® in adult patients is most pronounced in the acute period of the disease and is manifested by a reduction in the time for resolution of symptoms of the disease, a decrease in the severity of manifestations of the disease and a reduction in the time for elimination of the virus.
Therapy with Arbidol® leads to a higher frequency of relief of symptoms of the disease on the third day of therapy compared to placebo: 60 hours after the start of therapy, the resolution of all symptoms of laboratory-confirmed influenza is more than 5 times higher than the same indicator in the placebo group.
A significant effect of the drug Arbidol® on the rate of elimination of the influenza virus was established, which, in particular, was manifested by a decrease in the frequency of detection of viral RNA on the 4th day.
Refers to low-toxic drugs (LD50>4 g/kg). Does not have any negative effects on the human body when administered orally in recommended doses.
Is it possible to take Arbidol during pregnancy and lactation?
Arbidol during pregnancy should be used only as prescribed by a doctor. The drug is prohibited during the first 3 months of pregnancy, since the medicine has not been studied in women in this group.
It is permissible to use the medication for the prevention and treatment of acute respiratory viral infections in the 2nd and 3rd trimester if the benefit to the patient outweighs the possible negative effects on the embryo.
There is no data on the ability of the drug to penetrate the secretions of the mammary glands. If the medication is prescribed by a doctor, breastfeeding should be suspended for the entire period of therapy. During treatment, you need to pump regularly to maintain lactation.
Special conditions
If the drug is prescribed as a suspension to patients with diabetes, the sucrose that is present in the dosage form should be taken into account.
During therapy, you must strictly follow the instructions for use. If 1 dose was missed, it should be taken as soon as possible. And then the medicine is taken according to the schedule. It is not advisable to miss taking your medication at the scheduled time. Skipping a dosage reduces the concentration of the drug in the blood, which affects the effectiveness of therapy.
Attention! If symptoms of acute respiratory viral infection or flu do not subside within 3 days, you should consult a doctor for examination and treatment adjustment.
