Ayahuasca Overview

Olaparib Overview

  • Olaparib is used alone or in combination with bevacizumab (Avastin) to help maintain the response of certain types of ovarian (female reproductive organs where eggs are formed), fallopian tube (tube that transports eggs released by the ovaries to the uterus), and peritoneal (layer of tissue that lines the abdomen) cancer in people who have completely responded or partially responded to their first or later chemotherapy treatments. Olaparib is also used to treat certain types of breast cancer that has spread to other parts of the body and has not improved or has worsened after treatment with other therapies. It is also used to treat certain types of early breast cancer in people who have already been treated with other chemotherapy treatments. Olaparib is also used to treat a certain type of prostate cancer that has spread to other parts of the body, no longer responds to medical or surgical treatments to lower testosterone levels, and has progressed after treatment with enzalutamide (Xtandi) or abiraterone (Yonsa, Zytiga). Olaparib is also used to treat ovarian cancer that has not improved or has worsened after treatment with at least three other therapies. Olaparib is also used to help maintain the response of a certain type of pancreatic cancer that has not spread or progressed after the first chemotherapy treatment. Olaparib is a polyadenosine 5'-diphosphoribose polymerase (PARP) enzyme inhibitor. It works by killing cancer cells.
