The safety and effectiveness of activated Definity have not been established in the pediatric population. To this end, Twist Bioscience has teamed up with Imagene, a leading company in the field of room temperature biopreservation, to produce encapsulated synthetic RNA controls that are exceptionally stable at room temperature. Please see full Prescribing Information, including boxed WARNING regarding serious cardiopulmonary reactions. Always have cardiopulmonary resuscitation personnel and equipment readily available prior to Definity administration and monitor all patients for acute reactions. The pharmacokinetics of octafluoropropane gas (OFP) was evaluated in healthy subjects (n=8) after the IV administration of activated Definity at a 50 microL/kg dose.
