Question

1. which of the following drugs is an antiemetic?

inodium
tagamet
colace
antivert

Explanation:

Antiemetics are drugs that prevent or treat nausea and vomiting. Imodium (loperamide) is an antidiarrheal, Colace is a stool softener, Antivert (meclizine) is an antihistamine used for motion sickness/vertigo (not primarily antiemetic in the typical sense here). Tagamet (cimetidine) is a histamine - 2 blocker used for acid - related disorders, but among these options, Imodium is not an antiemetic. Wait, actually, Antivert (meclizine) can have antiemetic properties for motion - sickness related nausea. But there might be a typo, and if we consider the options, Imodium is for diarrhea, Colace for constipation, Tagamet for acid. Wait, maybe the correct one is Antivert? No, wait, maybe the question has a typo. Wait, actually, the correct antiemetic - like drug here among the options: Antivert (meclizine) is used for dizziness and nausea from motion sickness, so it has antiemetic effects. But let's re - check: Imodium (loperamide) is antidiarrheal, Tagamet (cimetidine) is H2 blocker for ulcers/acid, Colace (docusate) is stool softener. Antivert (meclizine) is an antihistamine that can reduce nausea from motion sickness, so it's an antiemetic - like drug. But maybe the intended answer is Imodium? No, that's wrong. Wait, maybe the question has a mistake, but among the options, Antivert is the one that can act as an antiemetic (for motion - related nausea). But let's confirm: Antiemetics are agents that prevent or alleviate nausea and vomiting. Meclizine (Antivert) is used for vestibular disorders and motion sickness, which involves nausea, so it's an antiemetic. So the correct option is Antivert? Wait, no, maybe I made a mistake. Wait, actually, the correct answer should be Imodium? No, Imodium is for diarrhea. Wait, maybe the question is misprinted. But based on the options, the answer is Antivert (the last option: Antivert). Wait, no, let's check again. The options are: Imodium, Tagamet, Colace, Antivert. Imodium: anti - diarrheal. Tagamet: H2 receptor antagonist (for acid). Colace: stool softener. Antivert (meclizine): antihistamine used for motion sickness, which causes nausea, so it's an antiemetic (to prevent vomiting from motion sickness). So the correct answer is Antivert.

Answer:

Antivert (the option with text "Antivert")
