Trabectedin is licensed for the treatment of advanced soft-tissue sarcoma when treatment with anthracyclines and ifosfamide has failed or is contraindicated. It is administered by intravenous infusion. Trabectedin may cause hepatobiliary disorders and for this reason hepatic function should be evaluated before starting treatment and during treatment. Dexamethasone is administered intravenously with trabectedin for its anti-emetic and hepatoprotective effects. As with other antineoplastic drugs, trabectedin causes nausea and vomiting and bone-marrow suppression as side-effects. 

After absorption, aprepitant is bound extensively to plasma proteins (>95%) it is extensively metabolized, primarily by hepatic CYP3A4, and is excreted in the stool its t is 9—13 hours. Aprepitant has the potential to interact with other substrates of CYP3A4, requiring adjustment of other drugs, including dexamethasone, methylprednisolone (whose dose may need to be reduced by 50%), and warfarin. Aprepitant is contraindicated in patients on cisapride (see above) or pimozide, in whom life-threatening ventricular tachyarrthmias has been reported.
