Rucaparib

Rucaparib is a prescription medication used to treat advanced ovarian cancer that is caused by a fault in the BRCA1 or BRCA2 gene. It is a type of drug known as a PARP inhibitor. Rucaparib works by blocking an enzyme called PARP (poly ADP-ribose polymerase). PARP helps cancer cells repair damage to their DNA, so blocking it can stop the cells from growing and multiplying. Rucaparib is taken as a pill once a day. Possible side effects include nausea, vomiting, diarrhea, fatigue, and anemia.

Rucaparib, also known by the brand name Rubraca, is a medication used to treat specific types of ovarian and prostate cancer [1, 2]. Here's a breakdown of its key points:

Function:

• PARP inhibitor: Rucaparib belongs to a class of drugs called poly (ADP-ribose) polymerase (PARP) inhibitors [1]. PARP is an enzyme involved in DNA repair within cells [3].
• Targets cancer cells: By inhibiting PARP, rucaparib hinders the ability of cancer cells, particularly those with specific genetic mutations, to repair their DNA damage. This ultimately leads to the death of cancer cells [2, 3].

Conditions it treats:

• Ovarian cancer: Rucaparib is approved for the maintenance treatment of recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer in adults with a deleterious BRCA mutation (germline and/or somatic) who have responded well to platinum-based chemotherapy [1]. BRCA refers to genes known as breast cancer susceptibility genes, and mutations in these genes can increase the risk of certain cancers [4].
• Prostate cancer: Under specific circumstances, it can also be used to treat metastatic castration-resistant prostate cancer (mCRPC) in adults with a deleterious BRCA mutation who have been treated with androgen receptor-directed therapy and taxane-based chemotherapy [1].

Administration:

• Rucaparib comes as tablets taken orally, typically once or twice daily with or without food [1].

Important considerations:

• Genetic testing: Rucaparib is most effective for individuals with specific BRCA gene mutations. Genetic testing is usually performed before starting this medication to determine if it's the right treatment approach [2].
• Side effects: Like many medications, rucaparib can cause side effects. Common ones include fatigue, nausea, vomiting, anemia, and low white blood cell count [1]. It's crucial to discuss potential side effects with your doctor and report any concerning symptoms promptly.
• Monitoring: Regular blood tests are necessary while taking rucaparib to monitor blood cell counts and potential side effects [1].
