Perflutren

Generic name: Perflutren
Drug class: Ultrasound contrast media

Usage of Perflutren

Perflutren is an ultrasound contrast agent that is used to improve the quality of an echocardiogram (ultrasound of the heart). Perflutren works by changing the way ultrasound waves travel within your heart. This helps the ultrasound portray a sharper image of your heart.

Perflutren is used to allow certain segments of the heart to be seen more clearly on an echocardiogram.

Perflutren may also be used for purposes not listed in this medication guide.

Perflutren side effects

Get emergency medical help if you have signs of an allergic reaction: hives, skin redness, itching; warmth, redness, numbness, or tingly feeling; wheezing, trouble breathing, tightness in your chest or throat; swelling of your face, lips, tongue, or throat.

In rare cases, serious or fatal reactions may occur during the injection or shortly afterward. Tell your caregivers right away if you have:

  • a light-headed feeling, like you might pass out;
  • severe dizziness, or a cold sweat;
  • chest pain, wheezing, trouble breathing;
  • fast or slow heartbeats;
  • severe headache, blurred vision, pounding in your neck or ears, anxiety, confusion; or
  • slow heart rate, weak pulse, fainting, weak or shallow breathing.

    • You may be more likely to have a serious reaction if you have severe or uncontrolled heart problems (congestive heart failure, a recent heart attack, serious heart rhythm disorder).

    Common side effects of perflutren may include:

  • headache, dizziness;
  • flushing (warmth, redness, or tingly feeling);
  • nausea;
  • chest pain;
  • pain in your side or lower back; or

  • if you have ever had an allergic reaction during a blood transfusion.

    How to use Perflutren

    Usual Adult Dose for Echocardiography:

    DEFINITY(R):-Administer by IV bolus or IV infusion immediately after activation in the VIALMIX(R) apparatus; if more than 5 minutes elapses before use, resuspend with 10 seconds of hand agitation.Bolus Dosing: -Administer 10 microL/kg IV bolus; follow with a 10 mL saline flush.-If necessary, a second 10 microL/kg IV bolus (followed with a 10 mL saline flush) may be administered 30 minutes later to prolong contrast enhancement.-Maximum dose: 2 bolus dosesInfusion Dosing:-Prepare an IV infusion by adding 1.3 mL activated Definity(R) suspension to 50 mL of preservative-free saline.-Begin IV infusion at 4 mL/minute; may titrate up to 10 mL/minute to achieve optimal image enhancement.-Maximum Infusion Rate: 10 mL/minute-Maximum Dose: One IV infusionComments: The safety of bolus and infusion dosing in combination or in sequence has not been studied. OPTISON(TM):-Dose should be individualized taking into account body habitus, intervening lung tissue, adequacy of transducer skin interface, and other acoustic factors. -Time from resuspension to injection should not exceed 1 minute, if time is exceeded, resuspend the microspheres.-Initial dose: 0.5 mL IV into peripheral vein at a rate not to exceed 1 mL per second; follow with a flush of NS or D5W.-Additional doses in increments of 0.5 mL up to a cumulative dose of 5 mL in a 10 minute period may be administered if contrast enhancement is inadequate. -Maximum dose per study: 8.7 mL Use: As an ultrasound contrast agent to opacify the left ventricular chamber and improve the delineation of the left ventricular endocardial borders in patients with suboptimal echocardiograms.

    Warnings

    Serious side effects may occur during the injection. Tell your caregiver if you feel dizzy, nauseated, light-headed, short of breath, or if you have a severe headache, pounding in your ears, chest pain, fast or slow heartbeats, wheezing, or shallow breathing.
