Bracanat 150mg Tablet is a prescription anticancer drug manufactured by Natco Pharma Ltd. It contains Olaparib as the active ingredient, with each tablet containing 150 mg of the compound. Olaparib is a PARP inhibitor (Poly ADP-ribose polymerase inhibitor), used as a targeted cancer therapy. It works by blocking the PARP enzyme, which helps repair damaged DNA in cells, thereby making it harder for cancer cells to survive and multiply, particularly in patients with BRCA mutations.
