Mechanism of Action Imuran 50mg (Azathioprine 50mg)

Azathioprine consist of purine analogue with cytotoxic and immunosuppressive activity. Azathioprine is a inactive formwhich is altered by hepatic xanthine oxidase to its active metabolite 6-mercaptopurine.

Then 6-MP is metabolized by hypoxanthine-guanine phosphoribosyl transferase into 6-thioguanosine-5'-phosphate and 6-thioinosine monophosphateboth prohibit nucleotide conversions and de novo purine development. This causes toprevention of DNA, RNA, and protein combination.

As a result, cell multiplication may be blocked, specifically in lymphocytes and leukocytes.

ADME of Imuran 50mg (Azathioprine 50mg)

Well absorbed, and maximum plasma radioactivity is 1-2 hours.

plasm protein binding is 30%.

Mostly azathioprine alters to the main metabolites 6-mercaptopurine and 6-thioinosinic acid via a non-enzymatic process and glutathione transferases. Stimulating of 6-mercaptopurine happen via hypoxanthine-guanine phosphoribosyl transferase (HGPRT) and a set of multi-enzymatic processes included kinases to form 6-thioguanine nucleotides (6-TGNs) as important metabolites.

Fastly eliminated from blood and in urine after 8 hours has no azathioprine or mercaptopurine is detectable.
