Description
Dutasteride Pharmacological action
Product for the treatment of benign prostatic hyperplasia. Inhibits the activity of 5? -reductase isoenzymes of types 1 and 2, which are responsible for converting testosterone into 5? -dihydrotestosterone. Dihydrotestosterone is the main androgen responsible for glandular hyperplasia of the prostate.
The maximum effect of dutasteride on the reduction of dihydrotestosterone concentrations is dose-dependent and is observed 1-2 weeks after the beginning of treatment. After 1 and 2 weeks of dutasteride therapy at a dose of 0.5 mg/day the average value of serum dihydrotestosterone concentrations is reduced by 85% and 90%.
Dutasteride helps to reduce the size of the prostate gland, improves urination and reduces the risk of acute urinary retention and the need for surgical treatment.
