Thallous Chloride
Identification
- Name
- Thallous Chloride
- Accession Number
- DB09316
- Description
Thallous chloride (also known as Thallium(I) chloride) is a colourless solid intermediate in the isolation of thallium from its ores. It is created from the treatment of thallium(I) sulfate with hydrochloric acid. This solid crystallizes in the caesium chloride motif. It is used as a diagnostic radiopharmaceutical. It is used for diagnosis of heart and parathyroid problems. The following are among the possible side effects: Blurred vision, chest pain or discomfort, chills, confusion, cough, difficulty with breathing, difficulty with swallowing, and dizziness.

- Mechanism of action
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.
- 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.
- Volume of distribution
3–10 L/kg
- Protein binding
Data not found.
- Metabolism
Data not found
- Route of elimination
Thallous Chloride Tl 201 is excreted slowly and to an equal extent in both feces and urine.
- Half-life
91% of the blood radioactivity has a t1/2 of 5 min. 9% has t1/2 of 40 hours.
- 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).

LD50 (mouse): 24 mg/kg. Minimum lethal dose (Human): 8 mg/kg. 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.
