- Brief Summary
The aim of this study is to evaluate the bioequivalence and safety of Tamsulosin hydrochloride 0.4 mg, prolonged-release tablets (Synthon Hispania SL, Spain), compared to Omnic Ocas®, Tamsulosin hydrochloride 0.4 mg, prolonged-release film-coated tablets (Astellas Pharma Europe B.V., the Netherlands), after single dose administration in healthy adult male subjects under fasting conditions.
- Detailed Description
In this Phase I study, the test medication Tamsulosin hydrochloride 0.4 mg, prolonged-release tablets (Synthon Hispania SL, Spain) is compared to the reference medication (Omnic Ocas®, Tamsulosin hydrochloride 0.4 mg, prolonged-release film-coated tablets by Astellas Pharma Europe B.V., the Netherlands) in terms of bioequivalence of the the tested formulations under fasting conditions.
