A normal-phase high-performance liquid chromatographic method was developed to determine therapeutic concentrations of trimethoprim, sulphamethoxazole, and its N4-acetyl derivative in biological fluids. The compounds are extracted at pH 6.2 using ethyl acetate--chloroform in a single extraction. The detection limit is

Chemotherapy, 28(4), 247-252 (1982-01-01)
A modified high-performance liquid chromatographic (HPLC) method for sensitive and rapid determination of trimethoprim, sulfamethoxazole and its metabolite N4-acetylsulfamethoxazole has been compared with the bioassay for trimethoprim and a colorimetric procedure for sulfonamides. The sensitivity of the (HPLC) method has

Journal of chromatography, 278(2), 337-345 (1983-12-09)
We describe a rapid, precise and simple procedure for the quantitative determination of trimethoprim, sulfamethoxazole, and N4-acetylsulfamethoxazole in body fluids by reversed-phase high-performance liquid chromatography. This method utilizes antipyrine as an internal standard with the compounds detected by dual-wavelength monitoring
