Definition:A sulfate salt resulting from the reaction of 2 eq. guanadrel with 1 eq. sulfuric acid. A postganglionic adrenergic blocking agent formerly used for the management of hypertension, it has been largely superseded by other drugs less likely to cause orthostatic hypotension (dizzy spells on standing up or stretching).
