Clindamycin is first of all an antibiotic, which is more effective for inflammation caused by bacterial infections, but less effective for inflammation caused by viral infections, mycoplasma and chlamydia infections. Clindamycin is a semi-synthetic derivative of lincomycin and has the same antibacterial spectrum as lincomycin. It is more effective in anaerobic bacteria, such as abdominal or gynecological infections caused by various anaerobic bacteria, and often requires combination with aminoglycosides to eliminate anaerobic bacterial infections. In addition, it can also be used for the treatment of infections of the respiratory system, joints, soft tissues, bone tissues, biliary tract and sepsis caused by sensitive gram-positive bacteria, which is more effective. For endocarditis, lincomycin and clindamycin are also more effective in reducing inflammation. If osteomyelitis of Staphylococcus aureus occurs, clindamycin is the drug of choice.
