HOW DO ANTINEOPLASTIC PARP INHIBITORS WORK?
Antineoplastic poly adenosine diphosphate-ribose polymerase (PARP) inhibitors are a class of drugs used to treat breast cancer, prostate cancer, ovarian cancer, fallopian tube (the 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 or partially responded to their first or later chemotherapy treatments.
PARP inhibitors are a group of pharmacological inhibitors of the enzymes, PARP-1 and PARP-2, which play an essential role in DNA repair. The inhibition of PARP enzymatic activity and increased formation of PARP-DNA complexes result in DNA damage and apoptosis (death of cells which occurs as a normal and controlled part of an organism’s growth or development).
They are a type of targeted therapy that works by preventing cancer cells from repairing and inducing cell death.
PARP inhibitors are administered orally as a tablet or a capsule twice daily with or without food.
PARP inhibitors work in the following ways:
- They are a targeted cancer therapy that works by inhibiting an enzyme in cells called "PARP" which plays a key role in DNA repair.
- Blocking PARP helps in preventing cancerous cells from repairing their damaged DNA, eventually leading to their death.
HOW ARE ANTINEOPLASTIC PARP INHIBITORS USED?
Antineoplastic PARP inhibitors are used to treat conditions such as:
- Ovarian cancer
- Breast cancer
- Pancreatic cancer
- Fallopian tube cancer
- Peritoneal cancer
- Metastatic castration-resistant prostate cancer
