Octafluoropropane
Octafluoropropane - General Information
Octafluoropropane, a diagnostic drug that is intended to be used for contrast enhancement during the indicated echocardiographic procedures, is comprised of lipid-coated microspheres filled with octafluoropropane(OFP) gas. When exposed to ultrasound waves, the microspheres resonate and "echo" strong signals back to the ultrasound machine. The difference in density between the gas-filled bubbles and the blood around them creates an increased level of contrast visible in the resulting ultrasound image. During echocardiography, activated Octafluoropropane enhances images of the inner edges or borders of the heart, producing an improved image that may enable physicians to better diagnose patients.
Pharmacology of Octafluoropropane
Octafluoropropane, a diagnostic drug that is intended to be used for contrast enhancement during the indicated echocardiographic procedures, comprised of lipid-coated microspheres filled with octafluoropropane(OFP) gas. It provide contrast enhancement of the endocardial borders during echocardiography. The perflutren lipid microspheres exhibit lower acoustic impedance than blood and enhance the intrinsic backscatter of blood.

Octafluoropropane Contraindications
Activated DEFINITY should not be administered to patients with known hypersensitivity to octafluoropropane or in patients with known cardiac shunts.
Activated DEFINITY should not be administered by direct intra-arterial injection.
Additional information about Octafluoropropane
Octafluoropropane Indication: Use in patients with suboptimal echocardiograms to opacify the left ventricular chamber and to improve the delineation of the left ventricular endocardial border.
Mechanism Of Action: Octafluoropropane is comprised of gas-filled microspheres that are injected or infused into the body. When exposed to ultrasound waves, the microspheres resonate and "echo" strong signals back to the ultrasound machine. The difference in density between the gas-filled bubbles and the blood around them creates an increased level of contrast visible in the resulting ultrasound image. During echocardiography, activated Octafluoropropane enhances images of the inner edges or borders of the heart, producing an improved image that may enable physicians to better diagnose patients.
