the Pharmacological

Pharmacokinetics Betagistin properties after intake is soaked up completely. At reception on an empty stomach of a betagistin, marked C14, the maximum concentration in blood plasma is observed about 60 minutes later.
Betagistin is brought, generally in the course of metabolism which are allocated with urine. 85-90% of the radioactivity connected with introduction of a dose of 8 mg are regenerated in urine 56 hours later. The maximum speed of discharge is observed in 2 hours after introduction. In case of intake the concentration of a betagistin in blood plasma is very low. So assessment of pharmacokinetic properties of medicine is based on definition in plasma of concentration of 2-pyridylacetic acid.
Proofs of presistemny metabolism of medicine are absent. It is estimated that discharge with bile does not play an essential role in medicine elimination, any of its metabolites.
Communication with proteins of blood plasma is weak or is absent, however betagistin is exposed to metabolism in a liver. About 80-90% of the entered dose are allocated with urine.
The pharmacodynamics

Polvertik’s efficiency at treatment of dizziness can be result of its ability to modify bleeding in an inner ear or direct influence on neurons in predoor kernels.
The single dose of Polvertik up to 32 mg at healthy faces brakes the induced nystagmus with the maximum effect 3-4 hours later from the moment of introduction. Higher doses show big efficiency in reduction of duration of a nystagmus.
Polvertik increases the capacity of an epithelium of lungs at people. It was proved as a result of observation of the reduced time of clearance of the radiotracer getting from lungs to blood. Slowing down of this action is carried out in view of preliminary oral administration of a terfenadin, the known blocker of receptors of H1.
The histamine has positive inotropic effect on heart. Increase in stroke output of heart in view of Polvertik’s use was not proved, but his action expanding blood vessels can cause a small lowering of arterial pressure in some patients. At people Polvertik has insignificant effect on glands of external secretion.
