What is Myoview 30ml?
From the FDA label:11.1 Chemical Characteristics MYOVIEW is a kit for the preparation of technetium Tc99m tetrofosmin injection for intravenous use. Technetium Tc99m tetrofosmin is a radioactive diagnostic agent. Each multiple-dose 10 mL glass vial contains a sterile, non-pyrogenic, lyophilized powder of 0.23 mg tetrofosmin [6,9-bis(2-ethoxyethyl)-3,12-dioxa-6,9-diphosphatetradecane], 0.03 mg stannous chloride dihydrate, (minimum stannous tin 0.015 mg; total stannous and stannic tin 0.0522 mg) 0.32 mg disodium sulphosalicylate, 1 mg sodium D-gluconate, and 1.8 mg sodium hydrogen carbonate. The lyophilized powder is sealed under a nitrogen atmosphere with a rubber closure. The product contains no antimicrobial preservative. The chemical formula of tetrofosmin is C 18 H 40 O 4 P 2 with the following structural formula: C 18 H 40 O 4 P 2 When sterile, pyrogen-free sodium pertechnetate Tc99m in isotonic saline is added to the vial, a Tc99m complex of tetrofosmin is formed. The radiolabeled product is a clear solution and the pH is in the range of 7.5 to 9.0. Chemical Structure 11.2 Physical Characteristics Technetium Tc99m decays by isomeric transition with a physical half-life of 6 hours. Photons that are useful for imaging studies are listed in Table 2.

How to use
Use appropriate radiation safety measures and aseptic technique during preparation and handling ( 2.1 , 2.3 ) The recommended dose range for MYOVIEW for rest or stress imaging is 185 to 1,221 megabecquerels (MBq) [5 to 33 millicuries (mCi)] by intravenous administration ( 2.2 ) When rest and stress injections are administered on the same day, the first dose should be 185 to 444 MBq (5 to 12 mCi) followed by the second dose of 555 to 1,221 MBq (15 to 33 mCi) given approximately 1 to 4 hours later ( 2.2 ) The recommended dose range for MYOVIEW for ventricular function assessment is 185 to 1,221 MBq (5 to 33 mCi) as an intravenous injection ( 2.2 ) See Full Prescribing Information for instructions for preparation and determination of radiochemical purity ( 2.4 , 2.5 ) Imaging may begin 15 minutes following administration of the agent ( 2.6 ) 2.1 Radiation Safety – Drug Handling Technetium Tc99m tetrofosmin is a radioactive drug and should be handled with appropriate safety measures to minimize radiation exposure during administration [see Warnings and Precautions (5.2) ] . Use waterproof gloves and effective shielding, including syringe shields, when preparing and administering technetium Tc99m tetrofosmin injection. 2.2 Recommended Dosage The recommended dose range for MYOVIEW is 185 to 1,221 megabecquerels (MBq) (5 to 33 millicuries (mCi) by intravenous administration for rest…
Side effects
The following clinically significant adverse reactions are described elsewhere in the labeling: Hypersensitivity Reactions [see Warnings and Precautions (5.3) ] Most common adverse reactions (incidence < 1%) after MYOVIEW injection: Cardiovascular: angina, hypertension, torsades de pointes. Gastrointestinal: vomiting, abdominal discomfort. Hypersensitivity: cutaneous allergy, hypotension, dyspnea. Special Senses: metallic taste, burning of the mouth, smell alteration. ( 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. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of MYOVIEW cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adverse reactions were evaluated in clinical studies (using an exercise/rest protocol) of 764 adults (511 men and 253 women) with a mean age of 58.7 years (range 29 to 94 years). The subjects received a mean dose of 285 MBq (7.7 mCi) on the first injection and 829 MBq (22.4 mCi) on the second injection of MYOVIEW. After MYOVIEW injection, angina occurred in 4 subjects, ventricular tachycardia in 1 subject, and respiratory arrest in 1 subject. The following reactions were noted in less…
Warnings
Important safety information
Risk with exercise or pharmacologic stress: Continuous cardiac monitoring should be performed in studying patients with known or suspected coronary artery disease ( 5.1 ) When pharmacologic stress is selected as an alternative to exercise, perform the procedure in accordance with the pharmacologic stress agent's prescribing information ( 5.1 ) Appropriate safety measures should be used to minimize radiation exposure to clinical personnel and to the patient consistent with proper patient management ( 2.1 , 5.2 ) 5.1 Risks Associated with Exercise or Pharmacologic Stress Patients evaluated with exercise or pharmacologic stress may experience serious adverse reactions such as myocardial infarction, arrhythmia, hypotension, bronchoconstriction, and cerebrovascular reactions such as headache, paraesthesias, convulsions, somnolence and cerebrovascular accident, including hemorrhage. Perform stress testing in the setting where cardiac resuscitation equipment and trained staff are readily available. When pharmacologic stress is selected as an alternative to exercise, perform the procedure in accordance with the pharmacologic stress agent's prescribing information. 5.2 Radiation Risks Technetium Tc99m contributes to a patient's overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk of cancer. Ensure safe handling and preparation radiolabeling procedures to protect patients and health care workers from unintentional radiation exposure. Encourage adequate hydration; instruct patients to void when the examination is completed and as often thereafter as possible [see Dosage and Administration (2.1) and (2.3) ] . 5.3 Hypersensitivity Reactions Hypersensitivity reactions including anaphylaxis, dyspnea, bronchospasm, throat tightness, coughing, tachycardia, chest pain, hypotension, abdominal pain, and cutaneous reactions (rash, urticaria, pruritus, erythema, and swelling or angioedema) have been observed after the administration of MYOVIEW. Always have cardiopulmonary resuscitation equipment and personnel available and monitor all patients for hypersensitivity reactions.
