Ibyra 150 mg Tablets Ibyra 150 mg is an oral anticancer medicine containing olaparib. It is a targeted treatment that interferes with the DNA-repair process inside cancer cells. By blocking PARP enzymes, olaparib can make it difficult for certain cancer cells, especially those with specific DNA-repair defects such as BRCA-related abnormalities, to repair themselves and continue growing. It is used for selected types of ovarian, breast, pancreatic, and prostate cancers based on the patient's cancer characteristics and treatment plan.
