Method: A randomized, single-dose, two-period, two-sequence, open-label, crossover design was employed. Subjects received a single oral dose of either the Test or Reference formulation under fasting conditions, with a 12-day washout period between treatments. Male subjects aged 18 - 45 years with normal health and laboratory values were included. Exclusion criteria encompassed any medical conditions, recent surgery, drug or alcohol use, and hypersensitivity to the study drugs. Blood samples were collected at pre-dose and multiple post-dose time points and analyzed using a validated LC-MS/MS method to quantify Rosuvastatin and Ezetimibe concentrations in plasma. Descriptive statistics were used to summarize pharmacokinetic (PK) parameters. ANOVA was conducted to compare the ln-transformed values of Cmax, AUC0−t, and AUC0−∞. Schuirmann’s two one-sided t-tests were applied to assess bioequivalence (BE). Results: The 90% Confidence Intervals for the ln-transformed ratios of Cmax, AUC0−t, and AUC0−∞ fell within the acceptance range of 80% to 125%, demonstrating bioequivalence between the Test and Reference formulations. Both formulations were well-tolerated, with no serious adverse events reported. Conclusions: The results of this study confirm the bioequivalence of the two tested FDC Rosuvastatin/Ezetimibe formulations: Cresadex® EZE (Abbott Laboratories) and Racor® Duo (Laboratorios Leti, S.A.V.). These findings endorse the therapeutic interchangeability of these products, providing clinicians with greater flexibility in the treatment of hyperlipidemia.展开更多
