1-Phenoxy-3-(4-phenylpiperazino)-2-propanol derivatives having the general formula
have been found to exhibit hypotensive action as well as both strong alpha-adrenergic blocking action and beta-adrenergic action and are useful as pharmaceuticals.

A series of 1-(aryloxy)-4-(4-arylpiperazinyl)-2-butanol derivatives were prepared and evaluated for antiallergy activity in the passive foot anaphylaxis (PFA) assay in rats. Twenty-seven derivatives had activity equal to or greater than the parent, alpha-(phenoxymethyl)-4-phenyl-1-piperazinepropanol. Six derivatives that possessed greater activity in the PFA than the parent compound were then tested in the guinea pig anaphylaxis (GPA) assay. Five of the derivatives were more potent than the parent (PD50 = 40 mg/kg) in the GPA with alpha-[(4-fluorophenoxy)methyl]-4-(4-fluorophenyl)-1-piperazinepropan ol (PD50 = 3 mg/kg) having the greatest potency.
