Resumen

Objetivos: Elaborar y evaluar tiras subgingivales combinadas compuestas por Ofloxacino y metronidazol in vitro con alginato de calcio biodegradable.

Métodos: las tiras se prepararon utilizando el método de evaporación del disolvente. Se usó una concentración del 10% de CaCl2 para la gelificación.de las tiras.

Resultados: el grosor de las tiras se encuentra dentro de las recomendaciones (>320 μm). In vitro, la liberación de la droga siguió una cinética bifásica que fue suficiente para alcanzar la CMI e inhibir el crecimiento de microorganismos durante 5 días. La “tasa de liberación de la droga” es inversamente proporcional a la concentración de polímero de la formulación. La liberación de la “droga” fue por difusión y en segunda fase por disolución.

Discusión: Las preparaciones OM1 y OM2 que contienen un 90 y un 75% de polímero respectivamente, podrían ser empleadas en liberación controlada durante cinco días en infecciones sublinguales. Siendo el alginato cálcico biodegradable una buena elección como polímero retardante
