Abstract: A method for preparing azoniaspironotropanol esters, esters thus produced, and methods of use for these is disclosed. The esters are effective as broncholytics and as agents in therapy of asthmatic conditions.

Abstract: The present invention is concerned with the use of azoniaspironortropanol esters of the general formula: ##STR1## wherein R signifies one of the following radicals: (a) an alkylene radical of the general formula: ##STR2## in which R.sub.3 is a hydrogen atom or an alkyl, benzyl, aryl or alkoxy radical and n is a whole number of from 1 to 4,(b) an alkenyl radical of the general formula: ##STR3## in which R.sub.4 and R.sub.5, which can be the same or different, are hydrogen atoms or alkyl or alkenyl radicals and n is a whole number of from 1 to 4,(c) an azaalkylene radical of the general formula: ##STR4## in which R.sub.6 is a hydrogen atom or an alkyl, alkoxycarbonyl or acyl radical and n is a whole number of from 2 to 4,(d) an oxaalkylene radical of the general formula:--(CH.sub.2).sub.n --O--(CH.sub.2).sub.
