Crizotinib is an orally active multi-target tyrosine kinase inhibitor which is the standard of care in patients with anaplastic lymphoma kinase translocated non-small-cell lung cancer. Common adverse events in clinical trials with crizotinib included visual disorders, nausea-vomiting, diarrhea and elevated transaminases. Less common toxicities are emerging, such as bradycardia and QT interval prolongation. We report on a case of a presyncopal episode which occurred under crizotinib and metoclopramide treatment.
