Abstract
The invention relates to new aminoethoxybenzylalcohol derivatives of the formula (I) ##STR1## wherein R.sub.1 is hydrogen, halogen, trihalomethyl, alkyl having from one to 4 carbon atoms or alkoxy having from one to 4 carbon atoms; PA0 R.sub.2 is halogen, trihalomethyl, or alkoxy having from one to 4 carbon atoms; PA0 R.sub.3 and R.sub.4 stand for methyl or together with the adjacent nitrogen form an up to 8-membered ring optionally containing oxygen, and acid addition or quaternary ammonium salts thereof. The compounds of formula (I) are pharmacologically active, thus show enzyme-inducing effect. The pharmaceutical compositions containing them as active ingredient are also within the scope of the invention.
