“In part because of interrupted supply, ultrasound contrast media usage has yet to reach its full potential, so we are quite pleased that GE Healthcare has made this commitment and investment to independently manufacture Optison within its own facility,” said Benjamin F. Byrd, III, MD, FASE, President, American Society of Echocardiography. “Optison remains an important diagnostic option for patients who present with suboptimal echocardiograms. The Society believes that use of contrast in echocardiography studies can enhance the image and thus reduce the need for additional testing, helping to lower healthcare costs and provide better patient care.”Optison offers a unique, convenient value to clinicians and patients: It is stable at room temperature for up to 24 hours and is quick to prepare, allowing for quick access to contrast in hospital settings like the cardiac lab or emergency room.
|Important Risk and Safety Information About Optison TM (Perflutren Protein-Type A Microspheres Injectable Suspension, USP)|
|BOXED WARNING: SERIOUS CARDIOPULMONARY REACTIONS: Serious cardiopulmonary reactions, including fatalities, have occurred uncommonly during or following perflutren-containing microsphere administration. Most serious reactions occur within 30 minutes of administration. Assess all patients for the presence of any condition that precludes Optison administration. Always have resuscitation equipment and trained personnel readily available.|
|INDICATIONS: Optison is indicated for use in patients with suboptimal echocardiograms to opacify the left ventricle and to improve the delineation of the left ventricular endocardial borders. CONTRAINDICATIONS: Do not administer Optison to patients with known or suspected: (1) Right-to-left, bi-directional, or transient right-to-left cardiac shunts, or (2) Hypersensitivity to perflutren, blood, blood products, or albumin. Do not administer Optison by intra-arterial injection. WARNINGS: Anaphylactoid Reactions: In postmarketing use, uncommon but serious anaphylactoid reactions were observed during or shortly following perflutren-containing microsphere administration, including in patients with no prior exposure to perflutren-containing microsphere products. High Ultrasound Mechanical Index: High ultrasound mechanical index values may cause microsphere cavitation or rupture and lead to ventricular arrhythmias. Additionally, end-systolic triggering with high mechanical indices has been reported to cause ventricular arrhythmias. The safety of Optison at mechanical indices greater than 0.8 and the safety of Optison with the use of end-systolic triggering have not been evaluated. PRECAUTIONS: General: Optison contains albumin, a derivative of human blood. Based on effective donor screening and product manufacturing processes, it carries an extremely remote risk for transmission of viral disease and Creutzfeldt-Jakob disease (CJD), no cases of which have ever been identified for albumin. Pregnancy: Adequate or well-controlled studies were not conducted in pregnant women. Optison should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nursing Mothers: It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Optison is administered to a nursing woman. Pediatric Use: Safety and efficacy have not been established in pediatric patients, or in patients with congenital heart disease. ADVERSE REACTIONS: The most frequently reported adverse reactions following clinical trial use of Optison were headache, nausea and/or vomiting, warm sensation or flushing, and dizziness. Postmarketing Experience: Cardiac arrests, and other serious, but non-fatal adverse reactions, were uncommonly reported. Most of these uncommon reactions included cardiopulmonary symptoms and signs such as cardiac or respiratory arrest, hypotension, supraventricular and ventricular arrhythmias, respiratory distress, or decreased oxygenation. Reports also identified neurologic reactions (loss of consciousness or convulsions) as well as anaphylactoid reactions. Prior to Optison administration, please read the Full Prescribing Information .|
