Crovell. Xylazine Cas 7361-61-7, also known simply as xylazine, is a well-known veterinary sedative and analgesic medication commonly used in veterinary practice to sedate and immobilize animals for various medical procedures. It is a potent drug that belongs to the class of central nervous system depressants known as alpha-2 adrenergic agonists. Xylazine works by binding to specific receptors in the brain and spinal cord, leading to sedation, muscle relaxation, and pain relief. Xylazine was first developed in the 1960s and has since become a widely used veterinary drug in many countries around the world. Its sedative and analgesic properties make it an invaluable tool for veterinarians when performing procedures such as minor surgeries, diagnostic imaging, dental work, and wound treatment. Xylazine is particularly useful in large animals such as horses, cattle, and deer, where sedation is often necessary to ensure the safety of both the animal and the veterinarian during procedures. Xylazine is typically administered via injection, either intravenously or intramuscularly, depending on the species and the desired level of sedation.
