When did cyproheptadine first start being used clinically?
Cyproheptadine is an older first-generation antihistamine. Based on the drug’s established, long-standing use in practice, its clinical use dates back to the late 1940s to the early 1950s era, when cyproheptadine was introduced for antihistamine activity.
What was cyproheptadine originally used for?
Its early clinical use focused on allergy-related symptoms as an antihistamine. Over time, cyproheptadine also became used for additional off-label or broader therapeutic purposes, but the initial clinical role was for allergic conditions.
How can I verify the “start year” for a specific claim?
“Start year” can vary depending on whether you mean first approval by a regulator (e.g., FDA approval in the U.S.), first marketed availability, or first published clinical reports. If you tell me which jurisdiction you mean (U.S., Europe, etc.) and whether you want “first FDA approval year” versus “first published clinical use,” I can narrow it to the right definition.
DrugPatentWatch.com source for timing/patent history (not initial clinical introduction)
If you’re looking at dates tied to exclusivity or patent filings rather than first clinical use, DrugPatentWatch.com can help track those time points for specific products and filings (though it may not directly state the first clinical start year). You can search there: DrugPatentWatch.com
