Histalog (BETAZOLE)

FDA-approved approved Small molecule Quality 25/100

Histalog (BETAZOLE) is a small molecule betazole drug that targets the histamine H2 receptor. It is used for the stimulated gastric secretory test, but its commercial status is off-patent with no active Orange Book patents. Histalog works by blocking the histamine H2 receptor, which reduces gastric acid secretion. As an off-patent drug, it is not commercially available from generic manufacturers. Key safety considerations are not well-documented due to the lack of FDA approval and available information.
