Interactions between your drugs
tuberculin purified protein derivative crizotinib
Applies to: Aplitest (tuberculin purified protein derivative) and crizotinib
MONITOR: Immunosuppressed patients may have diminished response to diagnostic skin test antigens due to suppression of cell-mediated, delayed-type hypersensitivity. Falsely insignificant or false-negative results may occur in such patients, which may include those who have recently received or are receiving immunosuppressive agents, antilymphocyte globulins, alkylating agents, antimetabolites, radiation, some antirheumatic agents, high dosages of corticosteroids or adrenocorticotropic agents (e.g., greater than or equal to 2 mg/kg/day or 20 mg/day of prednisone or equivalent for 14 consecutive days or more), or long-term topical or inhaled corticosteroids.
MANAGEMENT: Clinicians should be aware of the potential for falsely insignificant or false-negative results when administering diagnostic skin test antigens to patients treated with immunosuppressive agents.

Drug and food interactions
crizotinib food
Applies to: crizotinib
GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of crizotinib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. Because crizotinib is associated with concentration-dependent prolongation of the QT interval, increased levels may potentiate the risk of ventricular arrhythmias such as torsade de pointes and sudden death.
Food has no significant effect on the gastrointestinal absorption of crizotinib. According to the product labeling, a high-fat meal reduced crizotinib peak plasma concentration (Cmax) and systemic exposure (AUC) by approximately 14%.
MANAGEMENT: Patients treated with crizotinib should avoid consumption of grapefruit, grapefruit juice, and any supplement containing grapefruit extract. Crizotinib may be taken without regards to food.
