The disposition of sulfamethoxazole and trimethoprim, after constant rate intravenous administration (10 mg/kg/hr sulfamethoxazole and 2 mg/kg/hr trimethoprim for 1 hour), was investigated in adult patients with cystic fibrosis (n = 7) and in age-matched healthy subjects (control subjects, n

In this study, the biodegradation of sulfamethoxazole (SMX) as affected by temperature, humic acid (HA) and SMX concentrations was investigated by HPLC-MS/MS analysis based on water-sediment batch experiments. The first order decay model (C=C(0) × exp (-kt)) was best fitted
