Thymidine at levels as low as 0.05 mg/1 reduces the activities of sulphamethoxazole and trimethoprim and their combination in vitro. Using a biological assay procedure, levels of thymidine greater than this were interpreted as being present in urine. The addition of sulphamethoxazole and trimethoprim, singly or in combination, to urine obtained from patients with urinary tract infections showed...

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...
