Which drug is indicated for stimulating appetite?

The choice of Periactin, also known as cyproheptadine, is indicated for stimulating appetite due to its properties as an antihistamine with serotonin antagonist effects. This medication has been shown to effectively increase appetite and is often used in cases where appetite stimulation is desired, such as in patients with certain types of weight loss or conditions that affect appetite.

Metoprolol is a beta-blocker primarily used for managing hypertension and heart-related issues, while digoxin is utilized for heart failure and certain types of cardiac arrhythmias, neither of which are associated with appetite stimulation. Ibuprofen, on the other hand, is a nonsteroidal anti-inflammatory drug (NSAID) primarily used for relieving pain and inflammation, thus not related to appetite enhancement. Therefore, Periactin stands out as the correct choice for its specific indication in stimulating appetite.
