商品名：Biaxin and generic brands
Macrolide antibiotic, with bacteriostatic activity. It is a substituted 14-carbon macrolide. Clarithromycin was introduced in 1990 as a substitute for erythromycin. Compared to erythromycin it has higher absorption, a longer half-life, and increased intracellular uptake. Site of action is similar to other macrolide antibiotics, which is the 50-S ribosomal subunit in susceptible bacteria. Spectrum includes primarily gram-positive bacteria. Resistance is expected for most gram-negative bacteria. Clarithromycin may have higher activity (lower MIC values) for many bacteria compared to erythromycin
Most common use in people is for treatment of Helicobacter gastritis and respiratory infections, where it has retained activity against most respiratory tract pathogens (e.g., Streptococcus, mycoplasma, chlamydia). In small animals, clarithromycin has been used for indications such as skin infections and respiratory infections. In foals, clarithromycin has been used for treatment of infections caused by Rhodococcus equi (in combination with rifampin) and produced better clinical success than azithromycin.
