释义 | aprepitant A small molecule, high-affinity substance P antagonist (SPA) with antiemetic activity.

This agent has little or no affinity for serotonin type 3 (5-HT3), dopamine, and corticosteroid receptors. or A small, fingerlike pouch that sticks out from the cecum (the first part of the large intestine near the end of the small intestine). |
