Telmisartan-d3, a deuterated form of the angiotensin II receptor antagonist Telmisartan, is used in pharmacokinetic and metabolism studies due to its isotopic labeling with deuterium atoms (denoted by the "-d3" suffix). The deuterium substitution at specific positions in the molecular structure of Telmisartan (replacing hydrogen atoms with deuterium) enables researchers to trace its metabolic pathways and identify metabolites without interference from naturally occurring hydrogen.
