About medicine
Abiraterone (abiraterone) is a new generation drug used in prostate cancer. The essence of the drug is that it organizes the process of suppressing the CYP17 enzyme required for androgen biosynthesis. Androgens are hormones that are responsible for the development and maintenance of male sexual characteristics. Androgens also promote tumor growth. In the treatment of androgen-sensitive prostate cancer, orchidectomy is used, or luliberin agonists, but with these treatment methods, there is a decrease in hormone synthesis only in the testicles, whereas Abiraterone inhibits biosynthesis in both testicles and adrenal glands and in the tumor itself, thereby inhibiting biosynthesis in all 3 sources.
In studies of the effectiveness of Abiraterone, 1195 patients participated. Therapy with the use of abiraterone and prednisolone helped to reduce the risk of mortality among patients by 35%, and overall survival increased by 3.9 months. In addition, the drug contributed to the reduction of pain symptoms in a larger number of respondents than in the placebo group. Buy Abiraterone Acetate Price Abiraterone India

If signs of hepatotoxicity occur, use of abiraterone should be discontinued. The resumption of therapy is possible with the normalization of the relevant indicators. This may require a dose reduction of 500 mg / day. If hepatotoxicity develops with reduced doses, treatment with Abiraterone is no longer possible. Abiraterone is contraindicated in the case of the development of severe forms of hepatoxicity.
There is no need to adjust the dose in patients with mild hepatic or mild / moderate renal failure.
