Pharmacological Action

Clindamycin works by inhibiting or preventing the growth of bacteria. This drug disrupts bacterial protein synthesis which triggers changes in the surface of cell walls. This creates unfavorable conditions for bacteria to host cells and boosts intracellular killing of organisms.


Clindamycin treats some types of bacterial infections in different parts of the body such as internal organs, blood, lungs, skin and female reproductive organs. Unfortunately, clindamycin cannot treat flu, colds or other viral infections.
