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

Bioresource technology, 102(14), 7069-7076 (2011-05-21)
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
J Blaser et al.
Infection, 21(4), 206-209 (1993-07-01)
Serum kinetics of trimethoprim and sulfamethoxazole were studied in 23 patients during oral and i.v. treatment of Pneumocystis carinii pneumonia. Daily doses of 15-22 mg/kg trimethoprim and 75-110 mg/kg sulfamethoxazole were given every 6 h. Despite administration of a loading
