A Comparison of Three Drug Combinations Containing Clarithromycin in the Treatment of Mycobacterium Avium Complex (MAC) Disease in Patients With AIDS

Summary

To compare the efficacy and safety of clarithromycin combined with rifabutin, ethambutol, or both in the treatment of disseminated Mycobacterium avium Complex (MAC) disease in persons with AIDS, including individuals who have or have not received prior MAC prophylaxis. It is believed that effective therapy for MAC disease in patients with AIDS requires combinations of two or more antimycobacterial agents in order to overcome drug resistance and the unfavorable influence of the profound immunosuppression associated with AIDS. Data suggest that clarithromycin may have substantial activity in two- or three-drug combination regimens with clofazimine, rifamycin derivatives, ethambutol, or the 4-quinolones.
