Niraparib Tosylate API

Mechanism of Action

Niraparib works by blocking the activity of PARP enzymes, which leads to the accumulation of DNA damage and ultimately cell death in cancer cells. This mechanism of action is thought to be particularly effective in cancer cells that have deficiencies in homologous recombination DNA repair, such as those with mutations in the BRCA1 or BRCA2 genes.

Niraparib is indicated for the treatment of ovarian cancer, specifically in patients with deleterious or suspected deleterious germline or somatic BRCA-mutated (gBRCAm or sBRCAm) platinum-sensitive recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer. The medication is used as a maintenance treatment and is taken orally in tablet form.

Indication

Niraparib (brand name Zejula) is a medication that is indicated for the treatment of ovarian cancer. Specifically, it is indicated for the treatment of patients with platinum-sensitive recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who have been treated with two or more chemotherapeutic regimens and who have a deleterious or suspected deleterious germline or somatic BRCA-mutated (gBRCAm or sBRCAm) tumor.

Niraparib is a poly ADP ribose polymerase (PARP) inhibitor, which works by blocking the activity of PARP enzymes in cancer cells. This leads to the accumulation of DNA damage and ultimately cell death in cancer cells. The mechanism of action is thought to be particularly effective in cancer cells that have deficiencies in homologous recombination DNA repair, such as those with mutations in the BRCA1 or BRCA2 genes.

Niraparib is taken orally in tablet form and is used as a maintenance treatment, meaning it is taken after initial treatment with chemotherapy to help prevent the cancer from returning. The medication is used in combination with other treatments, as determined by a healthcare provider.
