Perflutren lipid microsphere is a contrast agent that is used to help provide a clearer picture during ultrasound scans.
Ultrasound is a diagnostic procedure that uses sound waves at a high frequency to create pictures of body parts. The sound waves bounce back' from different parts of the body and a clear picture can be seen by the ultrasound technician or doctor. Ultrasound dose not involve the use of any radiation as is found in X-rays.
Perflutren lipid microsphere contains certain lipid microspheres that contain a gas. This gas reflects the sound waves back to the imaging machine and enables a clearer picture to be developed. It is injected into the patient before the ultrasound begins and is used to assist in the diagnosis of conditions of the heart.
This medication should only be used under the direct supervision of a doctor who is trained in ultrasound procedures. This medication will not cure any conditions, rather it is used to help identify problems for treatment.
Perflutren lipid microsphere is administered as a suspension for injection.
In addition to helping to create a clear picture for an ultrasound, Perflutren lipid microsphere can also have unwanted side effects in the body. While not all of these may occur, if you do experience them you should inform your doctor and medical attention may be required in some cases.
You should immediately inform your doctor if any of the following side effects are experienced following the use of Perflutren lipid microsphere:
Other side effects can also occur that would not normally require that you seek attention from the doctor. If these side effects are ongoing or are particularly bothersome, however, then you can inform your doctor and seek advice on how to alleviate them. These side effects will normally be mild and will alleviate over time:

The usual dose given will be 10 microlitres per kg of weight. This is followed by a 10mL saline flush. A second dose may be administered after 30 minutes if it is required.

Perflutren lipid microsphere should be stored refrigerated between 2 and 8 degrees C. Once activated the solution may be stored for up to 12 hours before it needs to be disposed of if unused.
Perflutren lipid microsphere is a diagnostic treatment that is used to get a clear picture of your heart from an ultrasound scan. It is injected directly into the vein of the patient before the scan is carried out.
Perflutren lipid microsphere contains microspheres of gas that cause the frequency waves of the ultrasound equipment to bounce back. They fill the heart and enable the doctor to get a much clearer picture of the heart than would normally be possible. This allows them to diagnose certain conditions of the heart.
Patients may be asked to follow some steps in the days preceding the treatment. This may include the cessation of other medications or changes to diet. You should follow these steps exactly to enable an accurate diagnosis to be made.
Patients with certain diagnosed conditions of the heart should not be treated with this medication. Ensure that your doctor is aware of all of your medical conditions before receiving treatment.
Before beginning treatment with Perflutren lipid microsphere it is important that the patient weighs the risks of the treatment against the benefits. Certain life-threatening conditions may occur during this test.
