Feasibility of single low-dose olanzapine with triple antiemetic therapy for prevention of highly emetogenic chemotherapy-induced nausea and vomiting: a single-centre case series
Abstract
Background: Olanzapine works well as an antiemetic; however, it causes significant somnolence during the day and has additional side effects when used at a standard dose. Our goal was to evaluate the safety and effectiveness of low-dose olanzapine in patients with different cancers following highly emetogenic treatment.
Patients and Methods: This study was a retrospective, single-centre study in an Indian comprehensive cancer centre. Eight patients between the ages of 46 and 70 receiving cisplatin, a high emetogenic chemotherapy (HEC) drug, were chosen for different types of cancers and had an Eastern Cooperative Oncology Group performance level of 0–2. Patients underwent chemotherapy after receiving a prophylactic low-dose oral olanzapine regimen (2·5 mg) in conjunction with a triple antiemetic treatment. In the overall phase (0–120 hours), complete response (CR) and complete control (CC) were the major endpoints. The secondary outcome assessed safety according to the Common Terminology Criteria for Adverse Events V5.0 (CTCAE V5.0).
Results: All the studied patients were reported to have CR and CC. According to CTCAE v5.0, adverse effects grades varied from 0 to 1.
Interpretation: According to this study, prophylactic single low-dosage olanzapine (2·5 mg) was effective enough to prevent vomiting and nausea and reduce the incidence and severity of side effects in patients undergoing HEG; therefore, it should be deemed a new benchmark of care.
