The in vitro and in vivo spectrum of antibacterial activity of clarithromycin is summarized and related to its human pharmacokinetics. In vitro studies by several investigators have documented clarithromycin's activity against bacterial agents of respiratory tract infections, skin and soft tissue infections, and sexually transmitted diseases. Clinical cure rates of 52%-83% (pneumonia), 79%-96% (bronchitis), 82%-96% (pharyngitis), 58% (sinusitis), and 78% (skin/skin-structure infections) have been reported in patients receiving clarithromycin in comparative trials. Respective bacteriologic eradication rates in clarithromycin recipients have been reported as 57%-89%, 79%-96%, 88%-100%, 89%, and 90%. In vitro and in vivo studies suggest that clarithromycin, when combined with its major human metabolite, 14-hydroxyclarithromycin, is also effective against Haemophilus influenzae. A New Drug Application claiming efficacy in the treatment of lower respiratory tract infection, sinusitis, pharyngitis, and skin and skin-structure infections caused by susceptible pathogens has been filed with the Food and Drug Administration (FDA). This review summarizes relevant pharmacokinetic, microbiological, and clinical data for clarithromycin.
