Diabetes Mellitus. Activate DEFINITY RT by shaking the vial for 45 seconds using a VIALMIX RFID device. Before injection, this product must be activated and prepared according to the instructions outlined below. Higher room temperatures 27 - 32 C (80 - 90 F) may reduce the working times for . The risk for these reactions may be increased among patients with unstable cardiopulmonary conditions (acute myocardial infarction, acute coronary artery syndromes, worsening or unstable congestive heart failure, or serious ventricular arrhythmias). The product must be used within 5 minutes of dilution. Among the 1716 study patients, 19 (1.1%) suffered serious cardiopulmonary adverse reactions. In animal models the acoustic properties of activated Definity were established at or below a mechanical index of 0.7 (1.8 MHz frequency). Prior to activation, the headspace of each vial contains 6.52 mg/mL octafluoropropane and the clear liquid contains 0.75mg/mL of a lipid blend. The microsphere particle size parameters are listed in Table 11.1 below: Perflutren lipid microspheres exhibit lower acoustic impedance than blood and enhance the intrinsic backscatter of blood. The unactivated vial contains a colorless, uniformly clear to translucent (hazy), viscous, sterile, non-pyrogenic solution, which upon activation with the aid of a VIALMIX RFID and dilution with 0.9% Sodium Chloride Injection, USP, provides a homogeneous, hypertonic, milky white injectable suspension of perflutren lipid microspheres. This protocol ensured the stability of Definity . The risk for these reactions may be increased among patients with unstable cardiopulmonary conditions and/or with pre-existing PEG hypersensitivity [see Adverse Reactions (6.2)].
