The skin penetration of roxithromycin was studied in 27 surgical patients treated with 300 mg orally followed by three oral doses of 150 mg 12-hourly. Peak plasma and skin concentrations of 7.9 ± 1.2 mg/l and 31.3 ± 3.7 mg/kg occurred 2.5 and 4 h after last dosing respectively. The plasma and skin half-lives were 7.7 and 6.0 h, and the mean plasma and skin area under the curve values were 64.3 mg/l.h and 155.3 mg/kg.h. Skin/plasma concentration ratios were 4.9 ± 0.5, 9.7 ± 1.2, 7.6 ± 0.8 and 5.9 ± 1.1, at 3, 4, 5 and 6 h after last dosing respectively. These results demonstrate that roxithromycin achieves high levels in human skin.

Abstract
The skin penetration of roxithromycin was studied in 27 surgical patients treated with 300 mg orally followed by three oral doses of 150 mg 12-hourly. Peak plasma and skin concentrations of 7.9 ± 1.2 mg/l and 31.3 ± 3.7 mg/kg occurred 2.5 and 4 h after last dosing respectively. The plasma and skin half-lives were 7.7 and 6.0 h, and the mean plasma and skin area under the curve values were 64.3 mg/l.h and 155.3 mg/kg.h. Skin/plasma concentration ratios were 4.9 ± 0.5, 9.7 ± 1.2, 7.6 ± 0.8 and 5.9 ± 1.1, at 3, 4, 5 and 6 h after last dosing respectively. These results demonstrate that roxithromycin achieves high levels in human skin.File in questo prodotto:
