Pharmacokinetics of oral cephalosporins: cephradine cephalexin.

A crossover experiment was utilized to compare the pharmacokinetics of a 1-g dose of cephalexin tablets, cephalexin capsules, or cephradine capsules in nine normal human volunteers. These antibiotics were administered as three formulations: two 500-mg capsulin every 6 hr for five doses, and one 1000-mg tablet of cephalexin every 6 hr for five doses. Pharmacokinetic parameters in the experimental groups showed no statistical differences (p greater than 0.1), indicating that these drugs are equivalent pharmacokinetically.
