caffeine and Agrylin Interactions

Interactions between caffeine and Agrylin (anagrelide)

caffeine and anagrelide (Moderate Drug-Drug)

MONITOR: Theoretically, coadministration with drugs that are inhibitors of CYP450 1A2 may increase the plasma concentrations of anagrelide, which is a substrate of the isoenzyme.

MANAGEMENT: Clinicians should recognize the potential for interaction with drugs that inhibit CYP450 1A2 and monitor for evidence of anagrelide toxicities during coadministration. Since platelet reduction from anagrelide therapy is dose-related, thrombocytopenia may occur due to reduced clearance of anagrelide and may be a sign of overdosage. Patients should also be monitored for cardiovascular adverse effects such as tachycardia, palpitations, hypotension, edema, and congestive heart failure.
