After penetration into a cell which is infected with a virus the acyclovir under the influence of a thymidinekinase is transformed to an active acyclovir triphosphate. The last interacts with a virus DNA polymerase and is built in DNA which is synthesized for novy viruses. Thus defective virus DNA forms that leads to suppression of replication of novy generation of viruses.

Pharmacokinetics. The elimination half-life at persons with normal function of kidneys makes 2,9 h after intravenous administration. The most part of active agent is removed in not changed view with urine. Linkng with proteins of a blood plasma makes 9-33%. The only metabolite of an acyclovir is 9-karboksimetoksimetilguanin. At patients with a chronic renal failure the elimination half-life of an acyclovir increases. Concentration of active agent in cerebrospinal fluid makes about 50% of concentration in a blood plasma. Biotsiklovir well gets into fabrics, bodies and biological liquids of an organism: in a brain, kidneys, lungs, a liver, muscles, a spleen, a uterus, a mucous membrane of a vagina, a vaginal secret, medullispinal liquid and contents of herpetic bubbles.

For preparation of infusion solution the drug ex tempore is dissolved in 100 ml of isotonic solution of sodium of chloride or lactat solution of Ringer; in need of introduction of the dose exceeding 500 mg add adequate amount of solvent.

Preparation of infusion solution for children for whom doses on 10 mg and are necessary below is carried out in two stages; at first contents of a bottle are dissolved in 10 ml of water for injections or isotonic solution of sodium of chloride, and then the necessary amount of the received solution (corresponding to a dose) is added to infusion solution in the ratio 1:5 (for example, 4 ml to 20 ml).

Drug does not contain preservatives. Ready solution is steady during 12 h at a temperature from 15 ° C to 25 ° C. It is impossible to use solution in which opacification appeared or crystals were formed.

 Water for injections should not contain preservatives (benzyl alcohol or parabens).


Features of use:

At too bystry intravenous administration of a biotsiklovir and dehydration of an organism temporary increase in level of urea and creatine in blood serum therefore injection should be carried out slowly can be observed and to provide sufficient hydration of an organism.

Interaction with other medicines:
