Perflutren lipid microsphere Intravenous and Prexxartan

• Generic Name: perflutren
• Dosage Forms: n.a.
• Other Brand Names: Definity, Optison

Perflutren lipid microsphere preparation is an ultrasound contrast agent. Ultrasound contrast agents are used to help provide a clear picture during ultrasound. Ultrasound is a special kind of diagnostic procedure. It uses high-frequency sound waves to create images or “pictures” of certain areas inside the body. The sound waves produced by the ultrasound equipment can be reflected (bounced off) by different parts of the body, like for example, the heart. As the sound waves return they are electronically converted into images on a television screen. Unlike x-rays, ultrasound does not involve ionizing radiation.

The perflutren lipid microspheres preparation contains very small gas-filled lipid microspheres that reflect the sound waves and help create a better picture. The lipid microsphere preparation is given by injection into a vein before ultrasound to help diagnose problems of the heart.

Perflutren lipid microsphere is to be given only by or under the direct supervision of a doctor with specialized training in ultrasound procedures.

Valsartan is used alone or together with other medicines to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. Lowering blood pressure can reduce the risk of strokes and heart attacks.

Valsartan is also used to treat heart failure and left ventricular failure after a heart attack. Left ventricular failure occurs when the left side of the heart (the main pumping chamber) becomes stiff and enlarged or swollen. This causes pooling of blood in the lungs because the heart is not pumping properly.

Valsartan is an angiotensin II receptor blocker (ARB). It works by blocking a substance in the body that causes blood vessels to tighten. Valsartan relaxes the blood vessels and lowers blood pressure. A lower blood pressure will increase the supply of blood and oxygen to the heart.
