Olanzapine: Olanzapine is an FDA-approved antipsychotic medication that blocks dopamine, serotonin, and histamine receptors. 2 There is a growing body of literature to support the use of olanzapine for the prevention and treatment of CINV; olanzapine is also discussed within the clinical practice guidelines. 11-13 Olanzapine may be used in combination with palonosetron and dexamethasone for the prevention of CINV in moderate- and high-emetogenic chemotherapies. 12,13 Olanzapine has demonstrated a significant reduction in acute ( P <.0001) and delayed ( P <.004) nausea at a dose of 5 mg twice daily. 14 These outcomes add to the increasing number of studies supporting the role of olanzapine for CINV. Olanzapine may increase the risk of QT prolongation when used in combination with other QT-prolongation agents. It should also be used with caution with metoclopramide or phenothiazine antiemetics due to the increase risk of extrapyramidal side effects and excessive sedation. Clinicians should counsel patients regarding the risk of CNS depression, orthostatic hypotension, and an increased risk for falls. 12
What is the role of substance P in CINV?
The NK-1 receptor antagonists block substance P from binding to its neurokinin receptors and play a pivotal role in the prevention of delayed CINV. 9 There are three drugs in this class (aprepitant, fosaprepitant, and rolapitant). Aprepitant is an oral NK-1 receptor antagonist that crosses the blood-brain barrier and is given once daily for 3 to 4 days. Fosaprepitant, a prodrug of aprepitant, is given as a one-time IV dose. Aprepitant inhibits CYP3A4 and induces CYP2C9 metabolic pathways. This can lead to many significant drug-drug interactions (e.g., oral contraceptives, warfarin, and dexamethasone). 10 Rolapitant is the only medication in this class that is not an inhibitor of CYP3A4, which can be advantageous in avoiding some drug-drug interactions. Unlike other NK-1 antagonists, rolapitant does not need a dose reduction when combined with dexamethasone or other CYP3A4-metabolized medications. 3,11-13 Common adverse effects include diarrhea, fatigue, and neutropenia. 6
