Uses
1 INDICATIONS AND USAGE OPTISON is indicated for use in adult and pediatric patients with suboptimal echocardiograms to opacify the left ventricle and to improve the delineation of the left ventricular endocardial borders. OPTISON is an ultrasound contrast agent indicated for use in adult and pediatric patients with suboptimal echocardiograms to opacify the left ventricle and to improve the delineation of the left ventricular endocardial borders ( 1 ).
Dosage
2 DOSAGE AND ADMINISTRATION Adults 0.5 mL intravenously at a rate not exceeding 1 mL/s. If contrast enhancement is inadequate after the dose of 0.5 mL, additional doses of 0.5 mL may be repeated up to a total of 5 mL in a 10-minute period with a maximum total dose of 8.7 mL in any one patient study ( 2.1 ). Pediatric Patients 28 kg or less: 0.2 mL diluted with 0.2 mL of 0.9% Sodium Chloride Injection. 29 kg to 40 kg: 0.3 mL diluted with 0.3 mL of 0.9% Sodium Chloride Injection. 41 kg or more: 0.4 mL diluted with 0.4 mL of 0.9% Sodium Chloride Injection. Administer intravenously at a rate not exceeding 0.05 mL/s.
Side Effects
6 ADVERSE REACTIONS The following serious adverse reactions are described elsewhere in the labeling: Serious Cardiopulmonary Reactions [see Warnings and Precautions (5.1) ] Hypersensitivity Reactions [see Warnings and Precautions (5.2) ] Common adverse reactions (incidence ≥ 0.5%) were: headache, nausea and/or vomiting, warm sensation or flushing, dizziness, dysgeusia, chills or fever, flu-like symptoms, malaise/weakness/fatigue, chest pain, dyspnea, injection site discomfort, and erythema ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact GE HealthCare at 1-800-654-0118 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
Warnings
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 [see Warnings and Precautions (5.1) ]. Assess all patients for the presence of any condition that precludes OPTISON administration [see Contraindications (4) ]. 5 WARNINGS AND PRECAUTIONS Hypersensitivity Reactions: Serious anaphylactic reactions have been observed. Always have cardiopulmonary resuscitation personnel and equipment readily available prior to OPTISON administration and monitor all patients for hypersensitivity reactions ( 5.2 ). 5.1 Serious Cardiopulmonary Reactions Serious cardiopulmonary reactions including fatalities have occurred uncommonly during or shortly following perflutren-containing microsphere administration, typically within 30 minutes of administration. The risk for these reactions may be increased among patients with unstable cardiopulmonary conditions (acute myocardial infarction, acute coronary artery syndromes, worsening or unstable congestive heart failure, or serious ventricular arrhythmias). 4 CONTRAINDICATIONS OPTISON is contraindicated in patients with known or suspected hypersensitivity to perflutren or albumin [see Warnings and Precautions (5.2) ] . Known or suspected hypersensitivity to perflutren or albumin ( 4 )
Pregnancy
8.1 Pregnancy Risk Summary There are no data with OPTISON use in pregnant women to inform any drug-associated risks. No adverse developmental outcomes were observed in animal reproduction studies with intravenous administration of OPTISON to pregnant rats and rabbits during organogenesis at doses up to at least 5 and 10 times the recommended human dose based on body surface area ( see Data ). In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Storage
Storage and Handling Upon receipt, store OPTISON refrigerated between 2°C to 8°C (36°F to 46°F). Storage at room temperature (up to 25°C or 77°F) for up to 24 hours is permitted. Do not freeze.
