Pharmacological action


Pharmacodynamics and pharmacokinetics

Oseltamivir – pro-medicine. One of its active metabolitescarboxyarmour of an oseltamivir is the selection inhibitor of a neuraminidase of flu A and B. It is enzyme which activates release of viruses from the cells infected with them, is responsible for reproduction and distribution of harmful agents on all organism, in particular in an epithelium of respiratory tracts.

There are processes of suppression of replication of viruses and decrease in their pathogenicity. Also activity of allocation and distribution of agents from a disease carrier organism decreases.

Drug facilitates disease, reduces time of course of a disease, reduces probability of emergence of such complications as bronchitis, sinusitis, otitis or pneumonia. According to clinical trials children till 12 flyings have a decrease in duration of an illness for 2 days.

At preventive reception at the persons contacting to the infected patients at members of the family of the patient the probability to ache with flu decreases by 92%.

It is remarkable that means does not exert impact on intensity of fight of an organism against a disease, antibodies are developed normal. Clinically significant cases of emergence of resistance to medicine were not noted.

Phosphate of an oseltamivir quickly and almost is completely soaked up in a digestive tract where turns into an active metabolite, waters influence of intestinal and hepatic esterases. To find an active metabolite in a blood plasma becomes possible already through half of hour after reception. The metabolite reaches the maximum concentration in 2-3 hours. A metabolite in plasma in 20 times more, than the accepted oseltamivir.

Pharmacokinetic indicators of means do not depend on meal.

Active ingredient can be found in mucous a nose and bronchial tubes, in lungs, tracheas and a middle ear.

Extent of linkng of a metabolite with proteins in a blood plasma — to 3%, pro-medicine communicates almost and a half proteins, however does not influence any farmakodinamichesky parameters in any way.

Drug (and its active metabolite) through kidneys and with a stake is removed (in insignificant degree). The elimination half-life makes about five - ten hours.

The persons having serious diseases of kidneys can have difficulties with removal of means from an organism, AUC will be in inverse proportion to extent of defeat of bodies. At hepatic pathology of such pattern it was not observed.

Correction of a dosage of drug is not required from elderly patients.

At the children who did not reach age of 12 years, the metabolism of means accelerates, medicine is almost twice quicker brought out of an organism. In this regard correction of a daily dosage is required.
