原始语种摘要: The aim of this study was to establish and validate an in vitro-in vivo correlation that could predict the bioavailability of 4 oral long-acting formulations of doxycycline hyclate, acrylic acid and polymethacrylate matrices prepared using various proportions of doxycycline:acrylic acid:polymethacrylate for formulation 1 (1:0.25:0.0035), formulation 2 (1:0.5:0.0075), formulation 3 (1:1:0.015) and formulation 4 (1:2:0.0225) and a sample of doxycycline without excipients. In vitro dissolution profiles were obtained in phosphate buffer and hydrochloric acid media, which were fitted to several mathematical models. Plasma concentrations were obtained from 48 healthy dogs to achieve in vivo profiles. Therapeutic concentrations were observed for 60 h for formulation 1 and 4, 48 h for formulation...
