Brief Summary:
A single dose, two treatments (two cephalexin capsules 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 capsules (Optocef, BAYO5448 ) Drug: Cephalexin capsules (Keflex) Phase 1

Arm Intervention/treatment
Experimental: Arm 1 Drug: Cephalexin capsules (Optocef, BAYO5448 )
Single dose of 500 mg (One 500 mg capsule)

Active Comparator: Arm 2 Drug: Cephalexin capsules (Keflex)
Single dose of 500 mg (Two 250 mg capsules)

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 six weeks ]
