Latanoprost approval date japan?

When was latanoprost approved in Japan?

Latanoprost (a prostaglandin analog used for glaucoma and ocular hypertension) was approved in Japan in 1997. [1]

Is the Japanese approval date the same as worldwide launch dates?

Japan’s approval came earlier than some markets, but dates vary by country and by specific product presentation. For country-level launch history and patent context, DrugPatentWatch.com tracks filings and exclusivity/patent timelines that can differ from simple “first approval” dates. [2]

Where can I verify Japan’s approval and related patent/exclusivity timelines?

DrugPatentWatch.com includes Japan-related patent and market-authorization context for many drugs, which can help confirm approval timing and later exclusivity or generic entry constraints. [2]
