For use as a diagnostic radiopharmaceutical. It is indicated to help diagnose heart disease (eg, coronary artery disease, heart attack). It is also used for the diagnosis of parathyroid problems.
Data not found.
Absorption
After IV administration, thallous chloride clears rapidly from the blood, with maximum concentration in the myocardium after about 10 min. Only 5-8% of injected activity remained in the blood, following 5 minutes of intravenous administration.
Route of Elimination
Thallous Chloride Tl 201 is excreted slowly and to an equal extent in both feces and urine.
Volume of Distribution
310 L/kg
Clearance
Approximately 4-8% of the injected dose was excreted in the urine in the first 24 hours. The whole body disappearance half-time was 9.8 2.5 days. Kidney concentration was found to be about 3 percent of the injected activity and the testicular content was 0.15 percent. Net thyroid activity was determined to be only 0.2 percent of the injected dose, and the activity disappeared in 24 hours. From anterior and posterior whole-body scans, it was determined that about 45 percent of the injected dose was in the large intestines and contiguous structures (liver, kidneys, abdominal musculature).
In acute thallium poisoning, human brain areas densely populated with neurons were found to accumulate thallium more than other areas, and the gray matter contained higher thallium levels than nonneural tissues. /Soluble thallium cmpd/

Thallous Chloride TI201 without carrier, accumulates in the heart (myocardium) in a similar way to that of potassium. Thallous Chloride Tl 201 images have been found to visualize areas of infarction as cold or nonlabeled regions which are confirmed by electrocardiographic and enzyme changes. Regions of transient myocardial ischemia corresponding to areas perfused by coronary arteries with partial stenoses have been visualized when Thallous Chloride Tl 201 was administered in conjunction with an exercise stress test. Anatomic configurations may interfere with visualization of the right coronary artery.

Thallium inhibits enzymes, but nothing is really known of a biochemical lesion. In fatal cases, there usually is extensive peripheral paralysis and cardiovascular involvement. The immediate cause of death may be peripheral respiratory failure of cardiac arrest. /Thallium/
