Pharmacodynamics and pharmacokinetics


Tamsulozin competitively and selektivno blocks the postsynaptic adrenoceptors which are located in smooth muscles of a neck of a bladder, prostate and part of an urethra and body of a bladder that allows to lower a tone of smooth muscles of these bodies and to improve functions of a detruzor of a bladder. As a result of it the symptoms of irritation and obstruction connected with high-quality growth of ferruterous tissue of prostate gland decrease. The medical effect comes in 2 weeks of regular administration of drug. Thanks to sharp selectivity drug does not cause in patients of clinically significant change of the ABP.

Finasterid — specific inhibitor of enzyme of reductase which actively participates in transformation of testosterone in an active androgen — dihydrotestosterone (DGT). Functioning and growth of a prostate (hypertrophied fabric including), is defined directly by process of transformation of testosterone into DGT. Treatment by Finasterid for the short period reduces concentration of DGT in blood almost by 70% that promotes reduction of volume of a prostate. One-time administration of drug in a dose of 5 mg reduces concentration of DGT in blood in 24 hours by 75% which returns to initial level within 7 days.



It is actively soaked up in a small intestine, meal slows down absorption. Possesses high bioavailability (okolo100%). The maximum concentration in blood at a single dose is reached in 6 hours. Equilibrium concentration at a multiple dose of capsules of Tamsoluzin is reached for the fifth day, at the same time, its maximum concentration 2-3 times higher, than in case of a single dose. Communication with blood proteins high (about 99%).

Tamsulozin slowly is metabolized, biotransformation happens in a liver to formation of the active metabolites possessing selectivity to A-adrenoceptors. The considerable part of active agent is in blood in not changed look. Tamsulozin and the formed metabolites are removed by kidneys. An elimination half-life — 10-13 hours.


It is quickly soaked up from a gastrointestinal tract, at the same time, meal influences Finasterid's absorption does not render. Reaches the maximum concentration in blood in 2 hours. Absorption in a gastrointestinal tract after reception comes to the end in 6 hours. Finasterid's bioavailability makes about 80%.

Gets through GEB. Finasterid biotransformirutsya in a liver by oxidation to a number of metabolites. Removal happens through kidneys (about 40%) and intestines (50-60%). An elimination half-life — 6 hours.
