Study Summary

To determine if the drug combination sulfamethoxazole-trimethoprim (SMX-TMP), given by mouth, and the drug pentamidine (PEN), given by inhaled aerosol, are effective in preventing a relapse of Pneumocystis carinii pneumonia (PCP) when they are given to patients who have recovered from a first episode of PCP and are being given zidovudine (AZT) to treat primary HIV infection. AZT prolongs survival in patients with AIDS and decreases the occurrence of opportunistic infections such as PCP. However, PCP recurs in about 43 percent of patients receiving AZT, indicating a need for other treatments to reduce the relapse rate. The two medications to be tested in this study, SMX/TMP and aerosolized PEN, have also been partially effective in preventing recurrence of PCP. It is hoped that the combination of AZT with these medications will be more effective than AZT or one of the medications alone.
