Laferon

Name: Laferon Pharmacological action: Laferon has a wide spectrum of biological activity. Of primary importance is a pronounced immunostimulating and antiviral effect, activation of antitumor protection. Regulation is carried out between the links of humoral and cellular immunity. Under the influence of the drug, differentiation accelerates, and the activity of natural killer cells and T-lymphocytes, which determine the activity of cellular immune reactions, increases. Laferon regulates the production of inflammatory mediators, and also affects the migration of inflammatory cells to the site of infection, stimulates phagocytosis, and normalizes the dynamics of the inflammatory process. The effect of the drug on the expression of molecules in the major histocompatibility complex and the cytokine spectrum determines their antiallergic effect.

Laferon influences the main stages of pathogen replication inside cells, stopping their reproduction, ensuring the effectiveness of lysis of infectious agents. It also has high antichlamydial and antiviral activity. Its use in the complex treatment of infectious and inflammatory chronic diseases can significantly reduce the dose of antibacterial and other drugs used in treatment, reducing their toxic systemic effect and shortening the duration of treatment.

Use during pregnancy and lactation

The use of the drug has not been studied in pregnant women and nursing mothers.

Interaction with other drugs

Interferon alpha-2b is capable of reducing the activity of P-450 cytochromes and thereby influencing the metabolism of cimetidine, phenytoin, chimes, theophylline, diazepam, propranolol, warfarin, and some cytostatics. As a result, the neurotoxic, myelotoxic or cardiotoxic effects of these drugs may be enhanced. Caution should be used simultaneously with narcotic, sleeping pills and sedatives. Interferons can influence oxidative metabolic processes. This should be taken into account when used simultaneously with drugs that are metabolized by oxidation (including xanthine derivatives - aminophylline and theophylline). When used simultaneously with theophylline, it is necessary to monitor the concentration of the latter in the blood serum and, if necessary, adjust the dosage regimen. There are no data on negative interactions during complex therapy.

Contraindications

Established allergy to interferon and excipients of the drug.

Compound

Active ingredient: recombinant human interferon alpha-2b. The vial contains 1 million International Units (IU) of interferon. Excipients: sodium chloride, dextran 70, potassium dihydrogen phosphate, anhydrous sodium hydrogen phosphate.

Overdose

There were no cases of acute overdose of the drug.

Side effect

Short courses of treatment with interferon in the form of nasal drops do not cause any side effects.

Storage conditions

Store in a place protected from light, at a temperature of 2 °C to 8 °C. Keep out of the reach of children. After opening the bottle and preparing the solution, store the drug for 5 days in the refrigerator or 2 days at room temperature (15 °C to 25 °C).
