AMMONIA N-13 (UNII: 9OQO0E343Z) (AMMONIA N-13 - UNII:9OQO0E343Z)
University of Wisconsin System
INTRAVENOUS
PRESCRIPTION DRUG
Ammonia N 13 Injection is indicated for diagnostic Positron Emission Tomography (PET) imaging of the myocardium under rest or pharmacologic stress conditions to evaluate myocardial perfusion in patients with suspected or existing coronary artery disease. None Pregnancy Category C Animal reproduction studies have not been conducted with Ammonia N 13 Injection. It is also not known whether Ammonia N 13 Injection can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Ammonia N 13 Injection should be given to a pregnant woman only if clearly needed. It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for radiation exposure to nursing infants from Ammonia N 13 Injection, use alternative infant nutrition sources (e.g. stored breast milk or infant formula) for 2 hours (>10 half-lives of radioactive decay for N 13 isotope) after administration of the drug or avoid use of the drug, taking into account the importance of the drug to the mother. The safety and effectiveness of Ammonia N 13 Injection has been established in pediatric patients based on known metabolism of ammonia, radiation dosimetry in the pediatric population, and clinical studies in adults [see Dosage and Administration (2.4)].
Ammonia N 13 Injection is packaged in 10 mL mulitiple dose glass vial containing between 1.11 GBq to 11.1 GBq (30 mCi to 300 mCi) of [13 N] ammonia, at the end of synthesis (EOS) reference time, in 0.9% sodium chloride injection solution in approximately 8 mL volume. The recommended dose of radioactivity (10-20 mCi) is associated with a theoretical mass dose of 0.5-1 picomoles (8.47-16.94 picograms) of Ammonia. Storage Store at 25°C (77°F); excursions permitted to 15-30°C (59-86°F).Use the solution within 35 minutes of the End of Synthesis (EOS) calibration.

SEE FULL PRESCRIBING INFORMATION FOR AMMONIA N 13 INJECTION. AMMONIA N 13 INJECTION, FOR INTRAVENOUS USE INITIAL U.S. APPROVAL: 2007 INDICATIONS AND USAGE Ammonia N 13 Injection is a radioactive diagnostic agent for Positron Emission Tomography (PET) indicated for diagnostic PET imaging of the myocardium under rest or pharmacologic stress conditions to evaluate myocardial perfusion in patients with suspected or existing coronary artery disease (1). DOSAGE AND ADMINISTRATION Rest Imaging Study (2.1): Aseptically withdraw Ammonia N 13 Injection from its container and administer 10-20 mCi (0.368 – 0.736 GBq) as a bolus through a catheter inserted into a large peripheral vein. Start imaging 3 minutes after the injection and acquire images for a total of 10-20 minutes. Stress Imaging Study (2.2): If a rest imaging study is performed, begin the stress imaging study 40 minutes or more after the first Ammonia N13 injection to allow sufficient isotope decay. Administer a pharmacologic stress-inducing drug in accordance with its labeling. Aseptically withdraw Ammonia N 13 Injection from its container and administer 10-20 mCi (0.368 – 0.736 GBq) of Ammonia N 13 Injection as a bolus at 8 minutes after the administration of the pharmacologic stress-inducing drug. Start imaging 3 minutes after the Ammonia N 13 Injection and acquire images for a total of 10-20 minutes. Patient Preparation (2.3): To increase renal clearance of radioactivity and to minimize radiation dose to the bladder, hydrate the patient before the procedure and encourage voiding as soon as each image acquisition is completed and as often as possible thereafter for at least one hour.
