DIPHENIDOL HYDROCHLORIDE
Diphenidol hydrochloride is an anticholinergic and antiemetic medication used primarily to treat nausea and vomiting. It works by blocking acetylcholine receptors in the central nervous system, which helps reduce symptoms of motion sickness and postoperative nausea. Despite its efficacy, diphenidol is not widely used due to the availability of more modern alternatives with better safety profiles. The drug has no FDA-approved label, indicating limited regulatory approval or use in the United States. Common side effects include drowsiness, dry mouth, and blurred vision, which can affect up to 10% of users. Due to its limited market presence, current revenue and commercial data are not readily available.
