Conclusion
nausea and vomiting
The results of this trial support that the studied 4-drug antiemetic regimen is best at preventing nausea and vomiting associated with highly emetogenic chemotherapy. Cross-study comparison suggests that olanzapine may be a more effective antiemetic agent than any available NK-1 receptor antagonist. This is important information for sites that cannot obtain NK-1 receptor antagonists at a reasonable economic price.
