  • Injection solution for intramuscular and subcutaneous administration to animals
    Patent number: 5753636
    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.
