Benefits of technology

This patented technology relates to an injectable medication for use against various conditions related to animal's breathing or gastrointestinal systems like those associated with these illnesses. These drugs are effective at reducing symptoms while also being less harmful than traditional methods due to their ability to target specific areas within body lining fluid (BFL) rather than just relying solely on them themselves.

Problems solved by technology

This patents discusses different methods used during treating veterinary conditions like those related with ruminant feedings that can cause illness from various sources including viruses, germs, fungi, etc., especially when they come into contact with live horses. These agents may have negative effects on their health if taken incorrectly through these routes. However, current forms of medication require multiple steps before being able to effectively deliver them safely at home without causing harmful side reactions.

Abstract

The invention provides a lincomycin hydrochloride-spectinomycin sulfate injection and a preparation method thereof. Water for injection is taken as a carrier; and 100ml of injection contains 3 to 7g of lincomycin hydrochloride and 8 to 12g of spectinomycin sulfate. The invention has the advantages that the injection is safe and reliable, and has low toxic or side effect and high bioavailability; lincomycin hydrochloride-spectinomycin sulfate is prepared into a compound hydro-acupuncture injection, the injection has a synergistic effect and a relatively wide antibacterial spectrum, can remarkably strengthen the antibacterial activity on mycoplasmas, can act quickly, and has low toxicity, and the therapeutic dose of the injection does not have adverse affect on chickens and pigs; and the injection has a good effect of treating respiratory diseases of livestock, particularly mycoplasmal pneumonia, digestive tract diseases of the livestock, and chicken chronic respiratory diseases which are caused by mycoplasma gallisepticums, is favorable for reducing the medicine tolerance of medicines, and prolongs the service life of the medicines.
