New substituted 1H-imidazoles and their salts, processes for the preparation thereof and pharmaceutical compositions. These compounds have the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.5 =hydrogen or C.sub.1 -C.sub.4 -alkyl; R.sub.4 =hydrogen, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkoxy; Y.sub.1 =hydrogen and Y.sub.2 =OZ.sub.2 or the reverse; Z.sub.1 =Z.sub.2 =hydrogen or C.sub.1 -C.sub.4 -alkyl or Z.sub.1 and Z.sub.2 =--CH.sub.2 -- or --C(CH.sub.3).sub.2 --. These compounds are prepared either by reducing a corresponding imidazole compound having a hydroxyl or alkoxy group on the methyl bridge between the imidazole and phenyl rings, or by hydrolyzing a 4-[[2,2-dimethyl-4H-1,3-benzodioxin-6(or 8)-yl]methyl]-1H-imidazole, or yet by reducing an alkyl 3-[(1H-imidazol-4-yl)methyl]-2-hydroxybenzoate. These compounds have cardiac, cerebral and tissular anti-ischemic activities.
