Formation and elimination of sulphamethoxazole hydroxylamine after oral administration of sulphamethoxazole.

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 ...

Treatment of chancroid. A comparison of sulphamethoxazole and trimethoprim-sulphamethoxazole.

Since sulphonamides are no longer predictably effective in the treatment of chancroid the combination of trimethoprim-sulphamethoxazole (TMP-SMX) was evaluated to identify other effective regimens. One hundred and nine patients with genital ulcers (75 men and 34 women) seen at the Special Treatment Clinic in Nairobi, Kenya, were randomly assigned to treatment with a seven day course of either s...

Esch. coli endocarditis successfully treated with oral trimethoprim and sulphamethoxazole.

A 42-year-old patient was successfully treated for subacute bacterial endocarditis due to Esch. coli with oral trimethoprim and sulphamethoxazole. The treatment lasted nine months and was continued through a period of cholestatic jaundice superimposed on hepatic damage due to subacute bacterial endocarditis. There were no toxic effects attributable to the two antibacterials despite their prolon...

Interaction between warfarin and sulphamethoxazole.

A patient is described in whom there was strong circumstantial evidence of an interaction between warfarin and co-trimaxazole. To test the validity of this hypothesis a series of in vitro and in vivo human studies were untaken. The results indicate that interaction may occur in which the sulphamethoxazole moiety of co-trimoxazole displaces warfarin from its binding sites on plasma albumin. Neve...
