Abstract

The invention discloses a compound sodium sulfadimidine injection liquid for a pig and a preparation method thereof, aiming at providing a compound kanamycin sulfate injection liquid which has fast effect for treating toxoplasmosis of the pig, addresses both the symptoms and root causes, reduces the time and dosage of used drug and has convenient drug usage, and a preparation method with simple technique and easy implementation. Each 100L injection liquid comprises: 5 to 20 sodium sulfadimidine, 1 to 10kg of lincomycin hydrochloride, 5 to 20kg of doxofylline, 1 to 4kg of trimethoprim, 0.2kg of sodium bisulfite, 0.01kg of EDTA-2Na, 40kg of propylene glycol, 10kg of 95% alcohol and the balance of water for injection. The injection liquid has fast effect for toxoplasmosis of the pig, addresses both the symptoms and root causes, can effectively treat and prevent secondary infection of bacterium, reduces drug resistance of pathogenic microorganism and leads the pig to accelerate restoring. Simultaneously, the compound sodium sulfadimidine injection liquid is an injection liquid and has convenient use.

Description

technical field [0001] The invention relates to a compound sulfamethazine sodium injection for pigs and a preparation method thereof. Background technique [0002] Toxoplasma porcini infection is a common disease in pigs. The main clinical manifestations are high fever, depression, dyspnea, obvious enlarged lymph nodes, blood spots on the lower part of the body and ear tips, or large areas of cyanosis. With the prolongation of the disease, it is easy to continue. Other bacterial infections occur, the disease is highly contagious and has a high mortality rate. [0003] Due to the common occurrence of this disease in recent years, the flooding of drugs, the strong drug resistance of pathogens, the poor effect of ordinary single drug treatment, and the inability to quickly and effectively treat the disease due to no symptomatic treatment, or only symptomatic treatment, resulting in The death of pigs brings great losses to the farmers. Contents of the invention [0004] The ...
