Eprosartan mesylate, an angiotensin II receptor antagonist.

ABSTRACT: The title compound, eprosartan mesylate {systematic name: 2-butyl-1-(4-carb-oxy-benz-yl)-5-[(E)-2-carb-oxy-3-(thio-phen-2-yl)prop-1-en-yl]-1H-imidazol-3-ium methane-sulfonate}, C(23)H(25)N(2)O(4)S(+)·CH(3)O(3)S(-), one of the angiotensin II-receptor antagonists, is effective in regulating hypertension, induced or exacerbated by angiotensin II, and in the treatment of congestive heart failure, renal failure and glaucoma. In the eprosartan residue, which appears in this crystal in the cationic imidazolium form, the benzene ring plane is almost orthogonal to that of the imidazole ring, making a dihedral angle of 87.89 (2)°. The thio-phene ring forms dihedral angles of 66.54 (2) and 67.12 (2)° with the benzene and imidazole rings, respectively. The imidazolium NH group and the H atom of the ar
