Abstract
The invention relates to novel compounds of the general formula (I), ##STR1## The compounds of the invention antagonize the effects of constrictive mediators, e.g. histamine, acetylcholine or serotonin; they show an antiallergic action and possess an antiinflammatory effect. Thus, these compounds can therapeutically be used as bronchodilators as well as antiallergic or antiinflammatory drugs, particularly in the treatment of bronchial asthma.
