BACKGROUND: Clindamycin is frequently used for the treatment of bacterial pyoderma.
OBJECTIVE: To compare the pharmacokinetics of clindamycin in whole skin homogenates of normal dogs when administered orally at two dosage regimens (5.5 mg/kg BW, twice daily and 11 mg/kg BW, once daily).
ANIMALS AND METHODS: Skin biopsies were obtained from six laboratory beagles before, 3, 6 and 12 h after the first and the fifth dose of clindamycin at the former regimen, as well as before, 3, 6, 12 and 24 h after the first and third dose at the latter regimen. Tissue was homogenized and clindamycin concentrations were measured by reverse-phase high-performance liquid chromatography coupled with mass spectrometry. Results were analyzed using Student's t-test at a level of significance of 0.05.
RESULTS: Maximal concentration and area under the concentration-time curve, but not their relevant dose-normalized values, were higher at the dosage regimen of 11 mg/kg BW, once daily than at 5.5 mg/kg BW twice daily.
CONCLUSIONS: The pharmacokinetic profile of clindamycin is at least equal, if not better, when this antimicrobial is administered at 11 mg/kg BW, once daily.
