Tarafenacin is a potent and highly selective antagonist of the M3 muscarinic receptor (Ki = 0.19 nM), exhibiting approximately 200-fold selectivity versus the M2 subtype. This profile makes it a valuable research tool for investigating M3 receptor function in vitro and in vivo, particularly in studies of smooth muscle contraction and secretory processes.
