A Bioequivalence Study of Sacubitril/Valsartan Film-coated Tablets Under Fasting Conditions

A Bioequivalence Study of Two Formulations of Sacubitril/Valsartan 97 mg/103 mg Film-coated Tablets in Healthy Thai Subjects Under Fasting Conditions

Primary objective is to is to evaluate the bioequivalence of two formulations

The objectives of this study is to evaluate the bioequivalence of two formulations of sacubitril/valsartan 97 mg/103 mg film coated tablets, Entresto® (Reference) and Sacubitril and Valsartan Tablets 97mg/103mg (Test), after a single oral dose administration in healthy Thai subjects under fasting conditions and secondarily to examine the pharmacokinetics and safety of sacubitril, sacubitrilat and valsartan in healthy Thai subjects under fasting conditions
