Would you like the exact approval date and product details? I can look up the latest official info. In short: Teva has pursued and obtained regulatory approval for tadalafil as a generic in Japan (PMDA-approved), which would allow Teva to market tadalafil tablets in Japan, competing with the brand Cialis (Eli Lilly) and other generics. The typical Japanese strengths for tadalafil are 5 mg, 10 mg, and 20 mg, with indications for erectile dysfunction (and in some markets, benign prostatic hyperplasia). If you want, I can fetch the precise PMDA approval date, the approval/registration number, and current product availability from Teva.
