China Factory Supply Dutasteride Pharmaceutical Chemical CAS 164656-23-9

Product description

Dutasteride was launched for the symptomatic treatment of benign prostatic hyperplasia. Dutasteride can be prepared from 3-oxo-4-androstene-17β-carboxylic acid by several ways in 6 or 8 steps. Dutasteride is a dual inhibitor of type 1 and 2 isoforms of 5α-reductase unlike finasteride, the first marketed 5α-reductase inhibitor, which only acts on type 2 isozyme. Dutasteride is a 3-fold greater inhibitor of type-2 5α-reductase than finasteride in men and has greater effect on the type-l than on type-2 isozyme. In animal models,dutasteride exhibited superior efficacy and pharmacokinetics compared to finasteride. In patients with benign prostate hyperplasia, administration of dutasteride was shown to dose-dependently decrease serum dihydrotestosterone levels with greater efficacy as compared to finasteride (95% vs 67%). Serum testosterone levels increased with both active drugs, in conjunction with dihydrotestosterone suppression but remained within normal ranges. In long term studies, in men with moderate to severe benign prostate hyperplasia, once daily dutasteride significantly reduced prostate volume, reduced the risk of acute urinary retention and surgery by 57% and improved lower urinary tract symptoms and urinary flow measurements. After oral administration, dutasteride is rapidly absorbed, has a short distribution phase and a mean bioavailability of 60%. The high volume of distribution, combined with its low linear clearance results in a prolonged dose dependent half-life (from 3 days at low concentrations to 5 weeks at high concentrations) whereas finasteride’s half-life time is approximately 10 h. Dutasteride is well tolerated and the most occurring adverse events are impotence, decrease in libido, ejaculation disorders and gynaecomastia. Unlike a-blockers which primarily act acutely on benign prostatic hyperplasia symptoms, 5a-reductase inhibitors can alter disease progression. Concomitant administration of dutasteride did not affect the pharmacokinetics of either tamsulosin or terazosin. In addition, the tolerability of both terazosin and tamsulosin were improved during combination therapy.
