Clindamycin phosphate, an organic compound with the chemical formula C18H34ClN2O8PS, is a kind of antibiotic drug and a clindamycin derivative. It has no antibacterial activity in vitro and is rapidly hydrolyzed into clindamycin in the body to show its pharmacological activity. Therefore, the antibacterial spectrum, antibacterial activity and therapeutic effect are the same as clindamycin. However, the lipid solubility and permeability are better than clindamycin, and can be administered orally, intramuscular and intravenous.
