  • auxiliary component: sodium chloride - 3 mg.

Pharmacological properties


The active substance of Ridostin is an interferon inducer. The mechanism of its action is due to the ability of double-stranded RNA to induce the formation of endogenous interferons: immunogenic (gamma-Inf), leukocyte (alpha-Inf) and fibroblast (beta-Inf), which at the intracellular level suppress the reproduction of viruses and the development of intracellular microorganisms (for example, chlamydia), than prevent the development of the infectious process.

At the systemic level, the drug stimulates phagocytosis of macrophages and neutrophils. Acting on the T- and B-cell link, it has anti-Chlamydial and antiviral properties. By activating natural killers, it increases the body's resistance to infections.

Ridostin is an early type inducer. The maximum production of interferon is observed 2–6 hours after the administration of the drug, it returns to background values within 2 days.

In therapeutic doses, the drug is well tolerated. Does not cumulate, does not possess local irritating, mutagenic, sensitizing and teratogenic properties, does not affect reproductive function.


After i / m administration, Ridostin is rapidly absorbed, the maximum concentration in the blood reaches within 15 minutes. 60 minutes after administration, the drug is found in small amounts (<10%) in the tissues of the kidneys and liver, by the end of the first day in small amounts (2–3%) in the skin and gastrointestinal tract.

The main amount of the active substance (approximately 70%) is excreted from the blood within 4 hours after injection, mainly in the urine.

A repeated dose is administered 2 days later to patients who persist with fever, intoxication and the risk of exacerbation of chronic inflammatory diseases of the bronchi and upper respiratory tract;
  • simple, herpes zoster and genius herpes: 1 dose every 3 days for 9 days (the course includes 3 injections);

With the introduction of a dose that is 40 times higher than the recommended therapeutic dose, there were minor changes in metabolic processes (changes in the ratios of protein fractions in the blood, an increase in creatinine and alkaline phosphatase activity, a decrease in blood cholinesterase activity), a slight violation of blood circulation in the kidneys and intestines, the development of moderate lymph and leukopenic reactions. These violations are reversible, short-term and do not need additional corrective measures.
