Abstract

The invention relates to a novel veterinary preparation, namely sulfamonomethoxine suspension injection or sulfamonomethoxine sodium suspension injection, and a preparation method thereof. The preparation is prepared by using sulfamonomethoxine or sulfamonomethoxine sodium as a main drug and other auxiliary materials. The suspension injection comprises 1-45 percent (W / V) of the main component sulfamonomethoxine or sulfamonomethoxine sodium and medicinal auxiliary materials, wherein the auxiliary materials comprise a suspending agent, dispersion medium and an antioxidant. According to the preparation method, a long-acting sustained-release preparation is prepared from sulfamonomethoxine or sulfamonomethoxine sodium by using an oily solvent as a dispersion medium, is administrated in an intramuscular injection mode, can be used for remarkably prolonging the time of drug action in a body and reducing the number of administration times, and provides a stable plasma concentration to ill livestock. The suspension injection is safe, stable, effective and controllable in quality, and can be widely applied to livestock bacterial infection and parasitic infection.

Description

technical field [0001] The invention relates to a suspension used for treating diseases in animals, in particular to a sulfamethoxine suspension injection, a sulfamethoxine sodium suspension injection and a preparation method thereof. Background technique [0002] Sulfamethoxine is one of the sulfonamides with the strongest antibacterial effect in vivo and in vitro. The acetylated compound of this product has high solubility in urine and low toxicity, and has a good effect on the prevention and treatment of bacterial infections in livestock and poultry. In addition, it has a significant preventive effect on coccidiosis and toxoplasmosis in animals. my country first recorded in "Pharmacopia of the People's Republic of China" (1985 edition, 1990 edition), and later in "China Pharmacopoeia" [0003] Veterinary Pharmacopoeia of the People's Republic of China (1990 edition, 2000 edition, 2005 edition) recorded sulfamethoxine, sulfamethoxine sodium salt and its preparations. I...
