Diphenoxylate/Atropine is known by which brand name?

Diphenoxylate/Atropine is commonly recognized by the brand name Lomotil. This medication is primarily used to manage diarrhea by slowing down bowel movements. The combination of diphenoxylate, which is an antidiarrheal, and atropine, which is included to discourage misuse due to the potential for dependence, makes Lomotil effective for treating conditions that result in diarrhea.

The other options listed—Zantac, MS Contin, and Prilosec—are brand names for different medications that serve distinct purposes. Zantac (ranitidine) is a medication that reduces stomach acid production, MS Contin is a formulation of morphine used for pain management, and Prilosec (omeprazole) is a proton pump inhibitor that treats gastroesophageal reflux disease (GERD) and other conditions related to excessive stomach acid. Thus, Lomotil stands out as the correct answer for diphenoxylate/atropine.
