Gropivirin 500mg 50 tablets — Made in Ukraine — Free Delivery

Pharmacological properties

Pharmacodynamics. Gropivirin is an antiviral agent with immunomodulatory properties. the preparation eliminates the deficiency or normalizes (individual) dysfunction of cellular immunity, inducing maturation and differentiation of T-lymphocytes and T1-helpers, potentiating the induction of a lymphoproliferative response in mitogenic or antigen-active cells. Gropivirin  simulates the cytotoxicity of t-lymphocytes and natural killer cells, the function of t8-suppressors) and t4-helpers), and also increases the amount of igg and complement surface markers. Gropivirin increases the synthesis of interleukin (il) -1 and the synthesis of il-2, regulates the expression of il-2 receptors. Gropivirin significantly increases the secretion of endogenous γ-interferon and reduces the production of il-4 in the body. Gropivirin enhances the action of neutrophilic granulocytes, chemotaxis and phagocytosis of monocytes and macrophages. Gropivirin inhibits the synthesis of the virus by incorporating inosine-orotic acid into the polyribosomes of the cell affected by the virus and inhibits the attachment of adenylic acid to the viral irna.

Pharmacokinetics. After taking the preparation orally at a dose of 1.5 g, Cmax of inosine pranobex in blood plasma is reached after 1 hour and is 600 μg / ml. In the body of inosine, pranobex is metabolized in the liver to form uric acid. T1 / 2 of 4- (acetylamino) benzoate is 50 minutes, 1- (dimethylamino) -2-propanol - 3.5 hours. It is excreted in the urine as metabolites.

The course of treatment should be repeated as many times as necessary, while it is necessary to constantly monitor the patient's health status and indications for prolonging therapy.

For infections caused by the human papillomavirus (external genital warts (genital warts) or papillomavirus infection of the cervical canal), take 3 g (2 tablets 3 times a day) for 14-28 days as monotherapy or as an adjunct to local therapy or surgical treatment in accordance with the following schemes:

for the treatment of low-risk patients (patients with normal immunity or patients with a low risk of relapse), the preparation is used for 14-28 days until the maximum eradication of the virus is achieved, then a break for 2 months should be taken. The course of treatment can be repeated using the same dose, while constant monitoring of the patient's condition and indications for prolongation of therapy is necessary;

for the treatment of high-risk patients * (patients with immunodeficiency or with a high risk of relapse), the preparation is used 5 days a week, consecutively 1-2 weeks a month for 3 months. The course of treatment should be repeated as many times as necessary, while it is necessary to constantly monitor the patient's health status and indications for prolonging therapy.

Interactions

The preparation should not be taken concurrently with immunosuppressants. caution is required to prescribe a preparation with xanthine oxidase inhibitors or agents that promote the excretion of uric acid, including diuretics - thiazide diuretics (such as hydrochlorothiazide, chlorthalidone, indapamide) and loop diuretics (for example furosemide, torasemide, ethacrynic acid).

With simultaneous use with azidothymidine, nucleotide formation increases due to an increase in the bioavailability of azidothymidine in blood plasma and an increase in intracellular phosphorylation in human blood monocytes.

Overdose
