Class/mechanism: Purine (adenosine) analog, inhibitor of adenosine deaminase (ADA), causes elevated intracellular levels of dATP, and inhibits ribonucleotide reductase, which interferes with DNA synthesis. Pentostatin can also inhibit RNA synthesis and has been observed to cause DNA damage. ADA enzymatic activity is greater in T-cell malignancies compared to B-cell malignancies. Exact mechanism of action in hairy cell leukemia is not fully understood.
For conciseness and simplicity, HemOnc.org currently will focus on treatment regimens and not list information such as: renal/hepatic dose adjustments, metabolism (including CYP450), excretion, monitoring parameters (although this will be considered for checklists), or manufacturer. Instead, for the most current information, please refer to your preferred pharmacopeias such as Micromedex, Lexicomp, UpToDate (courtesy of Lexicomp), or the prescribing information.
