Groprinosin 500 mg No. 50 tablet.
Instructions for medical use of the drug Groprinosin Trade name Groprinosin International nonproprietary name Inosine Dosage form Tablets 500 mg Composition One tablet contains the active substance - inosine pranobex 500 mg, excipients: potato starch, povidone K-25, magnesium stearate. Description Tablets are white to cream in color, oval in shape with a biconvex surface, with a score line on one side, 17 mm long and 7 mm wide. Pharmacotherapeutic group: Direct acting antiviral drugs. Other antiviral drugs. ATC code J05AX05 Pharmacological properties Pharmacokinetics Absorption: inosine pranobex has high bioavailability and is rapidly absorbed. Distribution: the maximum concentration of inosine in plasma after oral administration is reached after 1 hour, the pharmacological effect appears after approximately 30 minutes and lasts up to 6 hours. Biotransformation and elimination: Inosine is metabolized in a cycle typical of purine nucleosides with the formation of uric acid, other components are excreted by the kidneys in the form of glucuronic and oxidized derivatives, as well as unchanged. No accumulation in the body was detected. Complete elimination of the drug and its metabolites occurs after 48 hours. Pharmacodynamics Groprinosin has an active substance - inosine pranobex, which exhibits direct antiviral and immunomodulatory effects. The direct antiviral effect is due to binding to the ribosomes of virus-infected cells, which slows down the synthesis of viral mRNA (impaired transcription and translation) and leads to inhibition of the replication of RNA and DNA genomic viruses; the indirect effect is explained by the powerful induction of interferon formation. The immunomodulatory effect is due to the influence on T-lymphocytes (activation of cytokine synthesis) and an increase in the phagocytic activity of macrophages. Under the influence of the drug, the differentiation of pre-T-lymphocytes is enhanced, the proliferation of T- and B-lymphocytes induced by mitogens is stimulated, the functional activity of T-lymphocytes increases, including their ability to synthesize lymphokines, and the ratio between the subpopulations of T-helpers and T-suppressors is normalized. Groprinosin significantly enhances the production of interleukin-2 by lymphocytes and promotes the expression of receptors for this interleukin on lymphoid cells. Stimulates the activity of natural killer cells (NK cells) in healthy people, stimulates the activity of macrophages for phagocytosis, processing and presentation of antigen, which contributes to an increase in antibody-producing cells in the body from the first days of treatment. It also stimulates the synthesis of interleukin-1, microbicidal activity, the expression of membrane receptors and the ability to respond to lymphokines and chemotactic factors. With herpetic infection, the production of specific antiherpetic antibodies is accelerated, clinical manifestations and the frequency of relapses are reduced. The drug also prevents post-viral weakening of cellular RNA and protein synthesis in infected cells, which is especially important for cells involved in the body’s immune defense processes. As a result of this complex action, the viral load on the body is reduced, the activity of the immune system is normalized, and the synthesis of its own interferons is significantly activated, which contributes to resistance to infectious diseases and rapid localization of the source of infection if it occurs. Indications for use - infectious diseases of viral etiology in patients with a reduced immune status: influenza, parainfluenza, acute respiratory viral infections, including rhinovirus and adenoviral infections, bronchitis of viral etiology, mumps, measles - herpetic infection caused by Herpes simplex I and II type (herpes of the lips, facial skin, oral mucosa, skin of the hands, ophthalmoherpes, genital herpes), Herpes (Varicella) zoster (chicken pox, shingles, including recurrent in patients with immunodeficiency) - infection caused by the human papillomavirus (HPV) types 16 and 18 - subacute sclerosing panencephalitis of viral etiology - chronic recurrent infections of the respiratory tract and genitourinary system in patients with weakened immune systems (chlamydia) Method of administration and dosage Groprinosin is taken orally, after meals and at regular intervals; If necessary, the tablet can be chewed, crushed and/or dissolved in a small amount of water immediately before use. The duration of treatment is determined individually, depending on the nosology, severity of the process and frequency of relapses; on average, the duration of treatment is 5 - 14 days, if necessary, after a 7 - 10-day break, the course of treatment is repeated; treatment with breaks and maintenance doses can last from 1 to 6 months.

Side effects Very common (≥1/10) - transient increase in the concentration of uric acid in the blood serum and urine caused by the metabolism of inosine Common (≥1/100 to <1/10) - headaches, dizziness - nausea, vomiting epigastric pain - allergic reactions: itching, skin rash - fatigue, weakness - joint pain - increased activity of aminotransferases, alkaline phosphatase or nitrogen in the blood - hyperurecemia Uncommon (≥1/1,000 to <1/100) - nervousness, drowsiness or insomnia - diarrhea, constipation - polyuria Contraindications - hypersensitivity to any component of the drug - gout, as well as patients with increased concentrations of uric acid in the blood and urine - urolithiasis - severe renal failure of the third degree - pregnancy and lactation (due to lack of experience in use) - children age up to 6 years Drug interactions Immunosuppressive agents may weaken the immunostimulating effect of Groprinosin. The drug should be used with caution in patients taking concomitant xanthine oxidase inhibitors, agents that increase uric acid excretion in urine, or diuretics. Special instructions Groprinosin is metabolized to uric acid. With continuous treatment for more than 14 days, it is necessary to monitor the level of uric acid in the blood serum and urine; for treatment for more than 21 days, it is advisable to monthly monitor liver and kidney function (transaminase activity, creatinine level), and the composition of peripheral blood. If uric acid levels increase during treatment, patients can be prescribed medications that lower their levels.
