Description

Valnemulin Hydrochloride is a semi-synthetic pleuromutilin derivative antibiotic, specifically formulated as its hydrochloride salt for enhanced stability and solubility. This compound is critically important for its potent antibacterial activity against Gram-positive pathogens, particularly those causing swine dysentery and mycoplasmal infections in veterinary medicine. It is an essential active pharmaceutical ingredient (API) for manufacturers of veterinary premixes, medicated feed additives, and injectable solutions targeting the global animal health industry.

Application

• Primary active ingredient in veterinary pharmaceuticals for the treatment and control of swine dysentery caused by *Brachyspira hyodysenteriae*.
• Key component in medicated feed and water-soluble powders for the prevention of respiratory diseases in swine, such as those caused by Mycoplasma hyopneumoniae.
• Manufacturing of injectable solutions for therapeutic intervention in bacterial infections in livestock.
• Used in veterinary premix formulations for growth promotion and disease prophylaxis in animal husbandry.
• Reference standard in analytical laboratories for quality control and regulatory testing of veterinary products.
• Research and development of novel antimicrobial agents within the pleuromutilin class.
