PHARMACOLOGY AND TOXICOLOGY Clindamycin Hydrochloride is a bacteriostatic antibiotic, which is 4 to 8 times more potent than Lincomycin. It has potent antibacterial activity to aerobic gram-positive bacterium, such as Staphylococcus, Streptococcus, Bacillus diphtheriae and Bacillus anthracis. It also has good antibacterial activity to anaerobic gram-negative bacterium. Bacteroides (including bacteroides fragilis) and Clostridium are morbidly susceptible to it. It binds exclusively to the 50'S subunit of sensitive bacterial ribosome and suppresses protein synthesis. Clindamycin is a bacteriostat, but can kill high sensitive bacterium at high concentration. Metronidazole is an anti-anaerobic bacterial, anti-trichomonal and anti-amebic agent. Combination of Clindamycin Hydrochloride and Metronidazole can kill Propionibacterium acnes, Pityrosporum ovale, and some other sensitive bacterium and vermiform mite, and can inhibit them from growing. As a result, it can reduce the creation of lipase, and prevent triacylglycerol from hydrolyzing into free fatty acid. INDICATIONS It is indicated for the treatment of acne (especially for the acne pustulosa, cystic acne), tympanitis, nasosinusitis, folliculitis, and other bacterial infection on skin. It is also indicated for the supportive treatment of seborrheic dermatitis and brandy nose.
