Formation and elimination of sulphamethoxazole hydroxylamine after oral administration of sulphamethoxazole.
The formation and elimination of sulphamethoxazole hydroxylamine in relation to the pharmacokinetics of the parent compound and its N4-acetyl metabolite were investigated in six healthy subjects after a single oral dose of 800 mg sulphamethoxazole. The apparent half-lives of sulphamethoxazole and its metabolites were approximately 10 h, indicative of formation rate-limited metabolism. The mean ...

متن کاملSimulataneous Analysis of Trimethoprim and Sulphamethoxazole Drug Combinations in Dosage Forms by High Performance Liquid Chromatography
A sensitive high performance liquid chromathography (HPLC) analytical procedure was developed for the quantitive determination of trimethoprim (TM* and sulphamethoxazole (SM) in commercial dosage forms. C18 analytical column (stainless steel, 25 cm * 4.6 mm i.d.) was packed with 5-*m particles of the reversed phase material and used for assays. Mobile phase containing 0.025 M sodium phosphate...
متن کاملIn-vitro activity of atovaquone, sulphamethoxazole and dapsone alone and combined with inhibitors of dihydrofolate reductase and macrolides against Pneumocystis carinii.
The anti-Pneumocystis carinii activity of atovaquone, dapsone and sulphamethoxazole alone and combined with dihydrofolate reductase (DHFR) inhibitors and macrolides was investigated against five clinical isolates of P. carinii. The susceptibility tests were performed by inoculation of the organisms on to cell monolayer and parasite count after 72 h incubation at 37 degrees C. Culture plates wer...
