Types of Antiemetic Drugs
If you’re experiencing nausea and vomiting, antiemetic drugs can help provide relief. These drugs work by blocking the signals in the brain that trigger these symptoms. Here are some types of antiemetic drugs that you should know about:
Serotonin Receptor Antagonists
Serotonin receptor antagonists, also known as 5-HT3 antagonists, are a type of antiemetic drug that works by blocking the action of serotonin in the brain. This helps to reduce nausea and vomiting. Some common examples of serotonin receptor antagonists include ondansetron (Zofran), granisetron (Kytril), palonosetron (Aloxi), and dolasetron (Anzemet).

NK1 Receptor Antagonists
NK1 receptor antagonists are a newer type of antiemetic drug that work by blocking the action of substance P in the brain. This helps to reduce nausea and vomiting. Some common examples of NK1 receptor antagonists include aprepitant (Emend) and rolapitant (Varubi).
Antihistamines and Anticholinergics
Antihistamines and anticholinergics are another type of antiemetic drug that work by blocking the action of histamine and acetylcholine in the brain. This helps to reduce nausea and vomiting. Some common examples of antihistamines and anticholinergics include dimenhydrinate (Dramamine) and meclizine (Bonine).
