Antihistamine antiemetic
block the hystamine receptors. good for vertigo and motion sickness
examples of antihistamine antiemetics

Prokinetic antiemetic
increases movement through Gi tract to treat delayed gastric emptying.
Example of prokinetic antiemetic
Reglan
Serotonin Blocker antiemetic
block receptors in gi tract, ctz, and vomiting centers.
Examples of serotonin blockers
