Pharmacokinetics of oral cefcanel daloxate hydrochloride in healthy volunteers and patients with various degrees of impaired renal function.

Cefcanel daloxate hydrochloride is a new oral cephalosporin prodrug. It is a double cephem ester of cefcanel, which is the active principle released in the body after uptake of an intermediate cephem mono ester. The present study investigated the pharmacokinetics of cefcanel following a single oral dose of cefcanel daloxate hydrochloride 300 mg to healthy volunteers and to patients with various degrees of stable renal insufficiency.

Pharmacokinetics of intravenous cefetamet and oral cefetamet pivoxil in children.

The pharmacokinetics of cefetamet were determined after intravenous (i.v.) administration of cefetamet and oral administration of cefetamet pivoxil syrup to patients between the ages of 3 and 12 years.

Comparison of the serum and tissue concentrations of cefuroxime from cefuroxime axetil and phenoxymethylpenicillin in patients undergoing tonsillectomy.

In the study described, the pharmacokinetics of two oral betalactams, cefuroxime axetil and phenoxymethylpenicillin, were compared with respect to their penetration into tonsil tissue. Seventeen patients were given cefuroxime axetil 500 mg single dose and 16 patients were given phenoxymethylpenicillin 650 mg single dose, at different time intervals before tonsillectomy. The tonsils were freeze-dried and the drug concentrations in serum and tissue determined by a high performance liquid chromatographic method.
