There have been 32 oral kinase inhibitors approved since 2001, 4 of which — ibrutinib, idelalisib, ponatinib, and ruxolitinib — are indicated for use in patients with hematologic cancers.1-4 These agents, all approved between 2011 and 2014, are indicated for several types of leukemias and lymphomas.

With the use of oral kinase inhibitors nurses must be aware of unique adverse effects associated with these drugs. Each agent has a different indication and recommended dose, and 2 have specific guidelines for administration (Table 1).
