Leveraging effect of the inhibitor RNA reductase – ribonukleoziddifosfatreduktazu causes inhibition of DNA synthesis. The drug has no effect on the synthesis of RNA and protein.

After intake of rapidly absorbed from the gastrointestinal tract. Maximum plasma concentrations of drug are achieved within 1-4 hours after ingestion. Receive write does not affect the absorption of the drug. Rapidly distributed throughout body tissues, it penetrates the blood-brain barrier. The cerebrospinal fluid is determined by 10-20%. a liquid aetsiticheskoy – 15-50% of plasma concentrations. The half-life – 3-4 hours. Partially metabolized in the liver and kidneys. 80% of hydroxyurea for 12 hours excreted in the urine, with 50% of unchanged form and in small quantities in the form of urea. The drug also appears to the airways in the form of carbon dioxide. After 24 hours, the plasma is not determined.

continuous therapy. From 20 to 30 mg / kg daily once a day.
Evaluation of efficacy is performed after 6 weeks of treatment. When expressed clinical remission treatment may be continued indefinitely. Treatment should be stopped if the white blood cell count less than 2500 / microliter and platelets less than 100,000 / microliter. After 3 days, a blood test is conducted repeatedly. Treatment is resumed when the content of white blood cells and red blood cells begins to increase significantly.

Treatment started with a daily dose of 15-20 mg / kg. Dose set individually, seeking to maintain a hematocrit level below 45%, and the number of platelets – less than 400,000 cells / mm. Most patients unable to achieve these indicators constantly applying Omnadren vs sustanon in a daily dose of 500 to 1000 mg.

Essential thrombocythemia
usually prescribe the drug in the initial daily dose of 15 mg / kg; then pick up a dose, which supports the platelet count at a level below 600,000 / microliter, without leading to a decrease in the number of counts below 4000 / mm.
