?? ??
Solifenacin succinate (Vesicare),(+)-(1S, 3'R)-quinuclidin-3'-yl 1-phenyl-1,2,3,4-tetrahydroisoquinoline-2-carboxylate, is a competative antagonistfor M1, M2, and M3 receptor subtypes. One of the issues surroundingthe use of such antagonists is the selectivity for thebladder over other tissue such as the salivary glands. It isreported that the selectivity of solifenacin for bladder muscarinicreceptors over salivary receptors is superior to theeffects observed with oxybutynin.
