Excretion rates of sulfamethoxazole and N4-acetyl-sulfamethoxazole by fresh water turtles Pseudemys scripta elegans.

T B Vree et al.

The Veterinary quarterly, 6(3), 169-173 (1984-07-01)

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

Assay of the acetyl-CoA probe acetyl-sulfamethoxazole and of sulfamethoxazole by gas chromatography-mass spectrometry.

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

High-performance liquid chromatographic quantitation of trimethoprim, sulfamethoxazole, and N4-acetylsulfamethoxazole in body fluids.

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

Determination of trimethoprim, sulphamethoxazole and its N4-acetyl metabolite in biological fluids by high-performance liquid chromatography.

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

Comparison of the conventional methods and high-performance liquid chromatography for the determination of trimethoprim, sulfamethoxazole and its metabolite in serum.

L Essers et al.

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
