Which medication is indicated for the treatment of acid stomach under the brand name Prevacid?

The medication indicated for the treatment of acid stomach under the brand name Prevacid is lansoprazole. Lansoprazole is a proton pump inhibitor (PPI) that works by reducing the amount of acid produced in the stomach. It is commonly prescribed for conditions like gastroesophageal reflux disease (GERD), peptic ulcers, and other conditions associated with excessive stomach acid.

Lansoprazole is effective in healing acid-related damage to the esophagus and relieving symptoms such as heartburn. Its formulation allows for longer-lasting acid suppression compared to some other medications, making it a preferred choice for chronic management of acid-related disorders.

In contrast, the other medications listed, while related to gastrointestinal health, are not associated with the brand name Prevacid. Omeprazole is another PPI but is marketed under a different brand name. Ranitidine is an H2 blocker that also reduces stomach acid but operates through a different mechanism. Diphenoxylate/atropine is an antidiarrheal medication and does not treat acid-related conditions. Understanding these distinctions helps clarify why lansoprazole is the correct answer in this context.
