Abstract: This invention relates to pharmaceutical compositions for veterinary use in form of aqueous injectable suspensions comprising Florfenicol or Florfenicol in form of a substantially water-insoluble complex, co-crystal or salt, sterile and micronised, in a concentration up to 500 mg/ml. The suspensions enable parenteral antimicrobial therapies in animals, with limited numbers of injections and showing good general- and local tolerances. They also possess a limited sedimentation on standing as well as after shipping, are easily resuspendable and have good syringablity.

Abstract: An injection solution for subcutaneous or intramuscular administration to an animal, and a method of producing same, are provided. The injection solution is substantially free of chloride ions and employs a basic amino acid as a pH-adjusting agent, characteristics that make the injection solution more physiologically tolerable upon injection. Preferably, the injection solution comprises 5 to 30 g of oxytetracycline per 100 ml of injection solution, where the oxytetracycline is provided in a magnesium complex; 0 to 25 g of polyvinylpyrrolidone per 100 ml of injection solution; a basic amino acid in an amount sufficient to adjust a pH of the injection solution to from 5.5 to 9.5; and an additive in an aqueous/organic solvent phase.
