Bioequivalence Study of Cefprozil 250 mg/ 5mL Powder For Oral Suspension Under Fed Conditions

The study was conducted as an open-label, randomized, 2-way crossover study to compare the single-dose relative bioavailability of Cefprozil 250 mg/5 mL Oral suspension versus Cefzil TM Powder for Oral Suspension (250 mg/5 mL) following one 5 mL dose under fed conditions
