Abstract

Un procedimiento para preparar una composición antibiótica estable que contiene una alta concentración del antibiótico en solución; caracterizado por hacer reaccionar un antibiótico de tetraciclina con una suspensión espesa que consiste de un compuesto alcalinotérreo farmacéuticamente aceptable y, si se desea, pirrolidona de polivinilo, en caprolactama o 2-piperidona acuosa para formar un quelato de metal alcalinotérreo/tetraciclina y ajustar el valor del pH, si es necesario para lograr una solución, el antibiótico se selecciona de oxitetraciclina, oxiciclina, clortetraciclina y las sales de adición de ácido farmacéuticamente aceptables de los mismos, con la condición de que cuando el antibiótico es clortetraciclina, el compuesto alcalinotérreo sea un compuesto de calcio soluble en la solución y cuando el antibiótico es oxitetraciclina o doxiciclina, el compuesto alcalinotérreo sea un compuesto de magnesio, soluble en esa solución.
