Summary for Patent: 4,138,581
Title: 3(Hydroxy or hydroxymethyl)-4(hydroxy)-.alpha.-(aminomethyl)benzyl alcohols
Abstract:Mono-, di- and tri-esters of 3-(hydroxy or hydroxymethyl)-4-hydroxy-.alpha.-(aminomethyl)benzyl alcohols, obtained by methods involving reduction of the corresponding mono- and di-ester ketones, are useful for producing sympathomimetic effects, such as bronchodilation, of long duration with low cardiovascular stimulating effect, in warm-blooded mammals.
