Main Function                                                                           

 

  Clindamycin is used primarily to treat infections caused by susceptible anaerobic bacteria, including infections of the respiratory tract, skin and soft tissue infections, and peritonitis.In patients with hypersensitivity to penicillins, clindamycin may be used to treat infections caused by susceptible aerobic bacteria as well. It is also used to treat bone and joint infections, particularly those caused by Staphylococcus aureus. Topical application of clindamycin phosphate can be used to treat mild to moderate acne.

 

 

Application                                                                                

 

It is a common topical treatment for acne and can be useful against some methicillin-resistant Staphylococcus aureus (MRSA) infections. The most severe common adverse effect of clindamycin is Clostridium difficile-associated diarrhea (the most frequent cause of pseudomembranous colitis). Although this side effect occurs with almost all antibiotics, including beta-lactam antibiotics, it is classically linked to clindamycin use.
