Qualitative and Quantitative Composition

Orange, round, biconvex, film-coated tablets, impressed ‘GX EL5’ and containing 25 mg Azathioprine BP in each tablet.

Chemical substance

Azathioprine is a pro-drug of 6-mercaptopurine (6-MP). 6-MP is inactive but acts as a purine antagonist and requires cellular uptake and intracellular anabolism to thioguanine nucleotides (TGNs) for immunosuppression. The TGNs and other metabolites (e.g. 6-methyl-mecaptopurine ribonucleotides) inhibit de novo purine synthesis and purine nucleotide interconversions.
