The invention relates to novel oxazolidine compounds of the formula (I) <IMAGE> in which R1 and R2 simultaneously denote hydrogen, or both denote the same lower alkyl radical or together stand for 4- to 7-membered lower alkylene, and their salts in racemic and chiral form, processes for the preparation of the said compounds, pharmaceutical preparations containing these and their use as pharmaceutical active ingredients. The compounds have a stimulant action on beta-adrenoreceptors and can be used, inter alia, in the treatment of diseases which are associated with reversible airways obstruction, such as e.g. asthma and chronic bronchitis, and also for inflammations of varying origin. |
