General information

Class/mechanism: Pan-histone deacetylase (HDAC) inhibitor, or HDACi. Inhibition of histone deacetylases results in hyperacetylation of histones and modulates gene expression by creating an open chromatin state that leads to expression of previously silenced genes. This modulation has been observed to be associated with decreased expression of oncogenes such as Bcr-Abl and HER-2, induction of cell cycle arrest, promotion of apoptosis, and decreased invasion of tumor cells.[1][2][3][4][5]
Route: PO
Extravasation: n/a

For conciseness and simplicity, 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]
