Used primarily in veterinary medicine and human antibiotics, this compound treats bacterial infections caused by susceptible Gram-positive organisms, especially staphylococci and streptococci. It is effective in treating respiratory tract infections, skin infections, and bone/joint infections when patients are allergic to penicillin. Commonly formulated in injectable and oral preparations, it works by inhibiting bacterial protein synthesis. Frequently used in aquaculture and livestock for controlling infections, particularly in swine and poultry. Also serves as a precursor for synthesizing clindamycin, a more potent derivative with broader antimicrobial activity.
