Thiotepa (Thioplex)
General information
Class/mechanism: Alkylator, ethylenimine-type, similar to nitrogen mustards. Ethylenimine radicals are released, which alkylates at the N7 position of guanine, resulting in the linkage between the purine and sugar being severed, and subsequent cell damage and death.[1][2]
Route: IV, intravesicular, intracavitary; (off-label: IT)
Extravasation: irritant or neutral, depending on reference
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.[1]
