O Spreux-Varoquaux et al.
Journal of chromatography, 274, 187-199 (1983-05-13)
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
Y Zhang et al.
Analytical biochemistry, 212(2), 481-486 (1993-08-01)
We present gas chromatographic-mass spectrometric assays for (i) the concentration of sulfamethoxazole and (ii) the concentration and molar percentage enrichment of acetyl-sulfamethoxazole in biological fluids. The compounds are extracted with ethyl acetate, derivatized with either diazomethane or pentafluorobenzyl bromide, and

Sulfamethoxazole and N4-acetylsulfamethoxazole are excreted by fresh water turtles Pseudemys scripta elegans in a biphasic mode, characterized half-lives of 5 and 100 min. Acetylation and deacetylation reactions cannot be detected below a dose of 50 mg/kg. The mass balance of

The Veterinary quarterly, 9(4), 381-384 (1987-10-01)
The turtle Pseudemys scripta elegans is able to hydroxylate and acetylate Sulphamethoxazole in a way that is comparable to man, i.e. the rate and yield of hydroxylation equals that of the acetylation. The hydroxy metabolites 5-hydroxy- and N4-acetyl-5-hydroxysulphamethoxazole are not
A Weber et al.
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
