Summary

The study will compare the relative bioavailability (rate and extent of absorption) of 200 mg/5 mL Azithromycin oral suspension manufactured by TEVA Pharmaceutical Industries Ltd.; distributed by TEVA Pharmaceuticals USA with that of 200 mg/5 mL ZITHROMAX oral suspension distributed by Pfizer labs, a division of Pfizer Inc. following a single oral 10 mL dose (400 mg) in healthy adult subjects administered under non-fasting conditions.

Clinical Details

Official title: A Relative Bioavailability Study of 200mg/5 mL Azithromycin Oral Suspension Under Non-Fasting Conditions

Study design: Allocation: Randomized, Endpoint Classification: Bio-equivalence Study, Intervention Model: Crossover Assignment, Masking: Open Label

Primary outcome:

Cmax - Maximum Observed Concentration

AUC0-inf - Area Under the Concentration-time Curve From Time Zero to Infinity (Extrapolated)

AUC0-t - Area Under the Concentration-time Curve From Time Zero to Time of Last Non-zero Concentration (Per Participant)

Detailed description: Detailed Description Criteria for Evaluation: FDA Bioequivalence Criteria Statistical Methods: FDA bioequivalence statistical methods Outcome: Confidence interval fell within 80-125% therefore met the FDA Bioequivalence criteria; no drug related, serious, unexpected adverse events were reported during the study.
