(Oxitriptan, NCI Thesaurus)

Palonosetron competitively blocks the action of serotonin at 5-hydroxytryptamine type 3 (5-HT3) receptors located on vagal afferents in the chemoreceptor trigger zone (CTZ), resulting in suppression of chemotherapy-induced nausea and vomiting.

(Palonosetron hydrochloride, NCI Thesaurus)

This agent also may block 5-hydroxytryptamine (5-HT) receptors and stimulate release of histamine from mast cells.

(Phentolamine, NCI Thesaurus)

This agent is a potent antagonist of 5-hydroxytryptamine type 2 (5-HT2), 5-HT3, and histamine 1 (H1) receptors, and a moderate antagonist of peripheral alpha 1 adrenergic and muscarinic receptors.
