Azathioprine drug class?

What drug class is azathioprine?

Azathioprine is an immunosuppressive medication that belongs to the antimetabolite class (specifically a purine analog/antimetabolite) used to suppress abnormal immune responses. It is commonly used in autoimmune conditions and to prevent organ rejection in transplant patients.

How does azathioprine work (mechanism)?

Azathioprine is converted in the body into active metabolites that interfere with purine (DNA/RNA building block) synthesis. By limiting purine availability, it reduces proliferation of immune cells, helping dampen the immune system’s activity.

What conditions is it used for?

Azathioprine is used to treat immune-mediated diseases and to prevent rejection after transplantation. Common real-world uses include autoimmune disorders (such as inflammatory bowel disease and other chronic autoimmune conditions) and maintenance immunosuppression in organ transplant settings.

Is azathioprine a chemotherapy drug?

Although azathioprine is an antimetabolite (a category that overlaps with some chemotherapy mechanisms), in routine practice it is usually prescribed as an immunosuppressant rather than as standard cancer chemotherapy.
