Pharmacology
Anastrozole is a selective non-steroidal aromatase inhibitor that suppresses estrogen biosynthesis by blocking the aromatase enzyme, significantly lowering serum estradiol concentrations in postmenopausal women without affecting adrenal corticosteroid or aldosterone formation.
Olaparib is an inhibitor of poly (ADP-ribose) polymerase (PARP) enzymes (PARP1, PARP2, PARP3) involved in DNA transcription and repair; cytotoxicity occurs through inhibition of PARP enzymatic activity and increased formation of PARP-DNA complexes, with enhanced activity in tumor cells harboring deficiencies in BRCA1/2, ATM, or other homologous recombination repair (HRR) genes.
