Descripción
Porous PVA microspheres were prepared to investigate their adsorption and release capacity ofoxytetracycline (OTC) in simulated biological fluid (SBF). The highest adsorption capacity of OTC during 2 hours was obtained at pH= 4, being 0.9 mg g-1. The release profile of OTC in SBF from the microspheres showed a burst effect with a cumulative release of 29±4 % within the first thirty minutes due to the immediate release of the OTC adsorbed on the surface of the microspheres, followed by a slower release reaching 41±5% within two hours,which in terms of concentration is equivalent to 4.2 μg/mL, a value close to the minimum inhibitory concentration of pathogens susceptible to OTC in injectable administration methods of therapeutic doses from 10 mg/Kg for farm animals.
