title: Concentrations of cefpodoxime in plasma, adenoid, and tonsillar tissue after repeated administrations of cefpodoxime proxetil in children.
abstract: Cefpodoxime proxetil was administered to 36 children undergoing tonsillectomy, adenoidectomy or both. It was very well tolerated. The detectable tissue concentrations of cefpodoxime were moderate but remained constant (approximately 0.05 mg/kg) 3, 6, and 12 h after the last dose of the drug, while the respective plasma concentrations were declining. This suggests the possibility of twice-daily administration. However, 30% of children did not have quantifiable concentrations in the tonsil and more than half the adenoids did not have quantifiable levels. Whether a higher dosage would lead to higher and more satisfactory tissue concentrations is a matter for further investigation.
