title: [Pharmacology of N-(2-imidazolin-2-yl)-N-(4-indanyl)amino (indanazoline), a new vasoconstrictive imidazoline compound].
abstract: In animal experiments the new imidazoline derivative N-(2-imidazolin-2-yl)-N-(4-indanyl)amine (indanazoline, E-VA-16, as monohydrochloride active substance of Farial) is characterized by a pronounced vasoconstrictive action after local or intravenous application. This is due to a direct action of the compound on alpha-adrenergic receptors. When applied systemically E-VA-16 being a peripherally acting alpha-sympathomimetic induces a rise in blood pressure and a reduction of heart rate and exerts antiphlogistic, spasmolytic, hyperglycemic and diuretic actions. When given by the intranasal route the substance influences blood pressure and heart rate only at concentrations considerably higher than those intended for use in therapy. After enteral administration the effective doses also markedly exceed the single therapeutic doses. There was no evidence of side-effects restricting the use of the drug as compared to other imidazoline derivatives. Studies on the isolated perfused rabbit ear, however, indicated a broader therapeutic range in local application.
