Olaparib is a medication that is available by prescription only to treat advanced ovarian cancer. It is also used to treat recurrent epithelial fallopian tube or primary peritoneal cancers. The FDA has recently expanded the approved use of olaparib to treat patients who have had chemotherapy with some kinds of metastatic breast cancer. Olaparib is only used to treat cancer patients who have already had three or more lines of chemotherapy.
Olaparib is a targeted chemotherapy drug that slows the growth of cancer cells in the body by inhibiting certain enzymes (poly [ADP-ribose] and polymerase [PARP]). These enzymes are involved in normal cellular activity in the body as well as the growth of cancerous cells.
Olaparib is a capsule that is taken orally, generally two times per day. It can be taken with or without food.
