Abstract: The present invention is related to pharmaceutical compositions capable of inhibiting or eliminating an infectious process caused by bacteria in warm-blooded animals. The present invention describes a stable formulation with a minimized methylpyrrolidone concentration. In order to reduce N-methylpyrrolidone concentration, a mixture was developed that eliminates the need to add preservatives and exhibiting a suitable viscosity and ensures the solubility of the composition when administered in drinking water at a ratio of dilution of up to 5,000 times in chlorinated or non-chlorinated water.

Abstract: The present invention relates to solid pharmaceutical compositions that dissolve readily and stably and which are capable of inhibiting or eliminating an infectious process caused by bacteria in warm-blooded animals and aquatic species such as, for example, fish and crustaceans. The invention describes composition for formulations containing antibiotics to be administered by various routes for treating bacterial infections in warm-blooded animals and aquatic animals. The formulation can be intended for human and animal use.
