Brief Summary:
A single dose, two treatments (two cephalexin suspension brands), two sequences, cross-over design was used with a washout of 7 days between the two study periods. Treatment groups balanced with the same number of healthy volunteers who were randomly (in two strata: male and female) assigned to the study drug administration sequences.

Condition or disease Intervention/treatment Phase
Anti-Infective Agents Drug: Cephalexin suspension (Optocef, BAYO5448) Drug: Cephalexin suspension (Keflex) Phase 1

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 26 participants
Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Prospective, Randomized, Open Label, Crossover Study to Compare the Bioavailability Between Optocef Suspension From Bayer (Cephalexin Suspension 250 mg/5 mL) and Equivalent Concentration of Keflex Pediatrico From Eli Lilly (Cephalexin Suspension 125 mg/5mL) in Healthy Subjects
Study Start Date : September 2009
Actual Primary Completion Date : September 2009
Actual Study Completion Date : September 2009

Arm Intervention/treatment
Experimental: Arm 1 Drug: Cephalexin suspension (Optocef, BAYO5448)
Single dose of 500 mg / 10 mL

Active Comparator: Arm 2 Drug: Cephalexin suspension (Keflex)
Single dose of 500 mg / 20 mL




Primary Outcome Measures :
  1. Least square estimator of average maximum plasmatic concentration (log transformed) [ Time Frame: After two months ]
  2. Least square estimator of area under the pharmacokinetic curve (log transformed) [ Time Frame: After two months ]

Secondary Outcome Measures :
  1. Time at which maximum concentration is reached [ Time Frame: After two months ]
  2. Area under the pharmacokinetic curve from time=0 to last blood sample [ Time Frame: After two months ]
  3. Clearance constant of plasmatic concentration of study drug [ Time Frame: After two months ]
  4. Half life of plasmatic concentration of study drug [ Time Frame: After two months ]
  5. Adverse events collection [ Time Frame: Up to 6 weeks ]
