Penetration of clindamycin into decubitus ulcers

Forty tissue samples, primarily of skin and bone, were obtained from 29 patients undergoing excision of decubitus ulcers after intravenous injection of 600 mg of clindamycin. Antibiotic concentrations exceeded 2.5 mug/g in 80% of the samples. In 50% of the instances, tissue levels were greater than those simultaneously present in the serum.
