AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
Thallous Chloride Tl 201 is a radioactive diagnostic agent approved in 1982 for myocardial perfusion imaging. It accumulates in viable myocardium analogous to potassium and visualizes regional coronary perfusion, identifying areas of infarction as 'cold' regions and transient ischemia during stress testing. The drug is administered via injection and relies on its Tl 201 isotope to correlate myocardial distribution with blood flow patterns.
LOE Approaching
A 40+ year-old diagnostic imaging agent nearing patent expiration faces moderate competitive pressure; brand teams are likely small and focused on retention in a legacy market.
Mechanism of Action
201 with no carrier added accumulates in viable myocardium in a manner analogous to that of potassium. Experiments in healthy subjects using labeled microspheres have shown that the myocardial distribution of thallous chloride Tl 201 correlates with regional perfusion. In clinical studies, Thallous…
