Indications and Usage:  
Cardiolite®, Kit for the Preparation of Technetium Tc99m Sestamibi for Injection, is a myocardial perfusion agent that is indicated for detecting coronary artery disease by localizing myocardial ischemia (reversible defects) and infarction (non-reversible defects), in evaluating myocardial function and developing information for use in patient management decisions. Cardiolite® evaluation of myocardial ischemia can be accomplished with rest and cardiovascular stress techniques (eg, exercise or pharmacologic stress in accordance with the pharmacologic stress agent's labeling).

It is usually not possible to determine the age of a myocardial infarction or to differentiate a recent myocardial infarction from ischemia.

Important Safety Information:
Exercise and pharmacologic stress testing should be performed only under the supervision of a qualified physician. Cardiolite® has been rarely associated with acute severe allergic events of angioedema and urticaria. The most frequently reported adverse events include headache, chest pain/angina, ST segment changes on ECG, nausea, and abnormal taste and smell.

Indications and Usage for Thallous Chloride TI-201 Injection
Thallous Chloride Tl-201 Injection may be useful in myocardial perfusion imaging using either planar or SPECT (single photon computed tomography) techniques for the diagnosis and localization of myocardial infarction.  It may also have prognostic value regarding survival, when used in the clinically stable patient following the onset of symptoms of an acute myocardial infarction, to assess the site and size of perfusion defect.

Thallous Chloride Tl-201 Injection may also be useful in conjunction with exercise stress testing as an adjunct in the diagnosis of ischemic heart disease (atherosclerotic coronary artery disease).

It is usually not possible to differentiate recent from old myocardial infarction, or to differentiate between recent myocardial infarction and ischemia.

Important Safety Information for Thallous Chloride TI-201 Injection
Adverse patient reaction to Thallous Chloride Tl-201 Injection is extremely rare. Rashes and/or temporary low blood pressure have occurred, which have been treated with no further reported complications.
