Abstract:
Background: The primary objective of this study is to investigate the bioequivalence of two formulations (test& reference) of Esomeprazole 40 mg MUPS Tablet in healthy, adult human subjects.
Method: In this study, a single dose, two-sequence, two-way crossover randomized design was used to investigate the bioequivalence under fasting conditions. 14 healthy volunteers received the two formulations over the course of two treatment days, each followed by a seven-day washout period. Following the administration of a single dose of 40 mg of each formulation, blood samples were taken at predetermined time points and subjected to a validated LC-MS/MS method for Esomeprazole concentration analysis. The plasma concentration-time profiles of both formulations were used to determine the pharmacokinetic parameters Cmax, AUC0-t, and AUC0-∞.
Result: Pharmacokinetic parameters Cmax, AUC0-t, and AUC0-∞ did not show any statistically significant differences. The 90 % confidence intervals of Cmax, AUC0-t, and AUC0-∞ for Esomeprazole was found 89.35% (82.27-97.03%), 107.61% (99.78-116.05%), and 107.72 (99.87-116.20%) respectively which is within predetermined bioequivalence acceptance limits of 80 - 125 %.
Conclusion: In terms of absorption rate and extent, the test product of Beximcopharmaceuticals has met the regulatory requirements for bioequivalence with the reference product Nexium MUPS.
