Dapsone 100 Mg Versus 50 as Primary Prophylaxis for Pneumocystis Carinii Pneumonia (PCP) in Patients With AIDS-Related Complex (ARC)
A study testing Dapsone in people with Pneumonia, Pneumocystis Carinii and HIV Infections, run by Jacobus Pharmaceutical at 1 site in United States.
Trial summary
To determine which of 2 doses of dapsone is effective prophylaxis for Pneumocystis carinii pneumonia (PCP) in patients with oral thrush or hairy leukoplakia and less than 400 CD4 lymphocytes per mm3. To determine whether the long-term toxicities associated with daily dapsone in this population are tolerable. Read more about this study
