Mechanism of Action Lynparza 50mg (Olaparib 50mg)
Olaparib belongs to targeted therapy. Olaparib is also called as poly (ADP-ribose) polymerase (PARP) enzyme inhibitor, involving PARP1, PARP2, and PARP3. PARP enzymes are containing in DNA transcription, cell cycle regulation, and DNA repair.
Olaparib belongs to potent oral PARP inhibitor which induces synthetic fatality in BRCA 1/2 deficient tumor cells via the formation of double-stranded DNA cutsthat cannot be accurately repaired, which causesdivision of cellular homeostasis and cell death

Drug interaction of Lynparza 50mg (Olaparib 50mg)
Concomitant use with myelosuppressive anticancer agents contains DNA damaging agents, indicate a potentiation and prolongation of myelosuppressive toxicity.
Combination of strong CYP3A inhibitors (itraconazole, telithromycin, clarithromycin,) will increase Olaparib plasma concentration.
Lynparza combination with strong CYP3A inducers (itraconazole, telithromycin, clarithromycin,) will decrease Olaparib plasma concentration.
