Palbociclib is a reversible, selective inhibitor of cyclin-dependent kinase (CDK) 4 and 6. Cyclin D1, CDK 4 and 6 are downstream of multiple signalling pathways which lead to cellular proliferation. Inhibition of CDK4/6 reduces proliferation of breast cancer cell lines by blocking progression from G1 into S phase of the cell cycle.
Neutropenia observed in clinical trials; febrile neutropenia also reported; monitor CBC count prior to starting drug and at the beginning of each cycle, as well as on Day 14 of the first 2 cycles, and as clinically indicated; dose interruption, dose reduction, or delay in starting treatment cycles is recommended for patients who develop grade 3 or 4 neutropenia

Increased plasma concentration and systemic exposure with strong CYP3A inhibitors (e.g. clarithromycin, telithromycin, itraconazole, ketoconazole, posaconazole, voriconazole, indinavir, ritonavir, ritonavir-boosted lopinavir, nelfinavir, saquinavir, telaprevir, nefazodone, verapamil). Decreased plasma concentration with moderate CYP3A inducers (e.g. bosentan, efavirenz, etravirine, modafinil, nafcillin) or strong CYP3A inducers (e.g. carbamazepine, phenytoin, enzalutamide, rifampicin). May increase the plasma concentration of CYP3A substrates (e.g. ciclosporin, everolimus, sirolimus, tacrolimus, dihydroergotamine, ergotamine, fentanyl, pimozide, quinidine).
