title: Mononuclear and polymorphonuclear leukocyte dispositions of clarithromycin and azithromycin in AIDS patients requiring Mycobacterium avium complex prophylaxis.
abstract: The intracellular dispositions of clarithromycin and azithromycin in AIDS patients requiring Mycobacterium avium complex (MAC) prophylaxis were studied. The dispositions of both drugs in mononuclear and polymorphonuclear leukocytes were markedly different. Our data support the proven efficacy of these agents for MAC prophylaxis since clarithromycin and azithromycin displayed sustained intracellular concentrations which exceeded their MICs for MAC throughout the dosing periods.
