A Randomized, Comparative, Prospective Study of Daily Trimethoprim / Sulfamethoxazole (TMS) and Thrice-Weekly TMS for Prophylaxis Against PCP in HIV-Infected Patients

Summary

To compare the safety and efficacy of two dosage regimens (daily and thrice-weekly) of sulfamethoxazole/trimethoprim (SMX/TMP; TMS) in the prevention of Pneumocystis carinii pneumonia (PCP) in high-risk HIV-infected patients. Previous tests have shown that SMX/TMP given daily is effective in preventing recurrence of PCP and may be effective in preventing PCP in patients who have never developed it. Because SMX/TMP can cause side effects, this study will attempt to determine the safest and most effective dose of this combination.
