title: The effect of cotrimoxazole on the absorption of orally administered 6-mercaptopurine in the rat.
abstract: The effect of cotrimoxazole (CTX) on plasma levels of 6-mercaptopurine (6-MP) was studied in the rat. Animals receiving CTX in conjunction with 6-MP were found to have a marked but non-significant decrease in the area under the plasma time curve as compared with animals receiving 6-MP alone. It is suggested that the bioavailability and thereby, the antileukaemic effect) during maintenance therapy of ALL of 6-MP may be decreased by the co-administration of CTX.
