Drug Mode of Action ::  

Mercaptopurine is a purine antagonist which is converted intracellularly into its active nucleotides, including thioinosinic acid. The nucleotides inhibit several reactions which ultimately interferes with nucleic acid synthesis and prevents the formation of RNA and DNA.

Drug Interactions ::

Anticoagulant action of warfarin may be inhibited by mercaptopurine. Enhanced toxicity with myelosuppressive drugs. Potentially Fatal: Effects enhanced by allopurinol (reduce dose of mercaptopurine). Other hepatotoxic drugs (e.g. doxorubicin) potentiate toxicity.
