Abstract

1356379 Anti-asthmatic &c medicines FISONS Ltd 13 Aug 1971 [27 Aug 1970 1 July 1971] 41225/70 and 30828/71 Heading A5B [Also in Division C2] Therapeutic compositions for administration orally or by inhalation, and optionally in combination with a bronchodilator such as isoprenaline, comprises compounds of formula and their pharmaceutically acceptable salts, wherein R<SP>1</SP>. . R<SP>6</SP> are each A, halogen or (possibly substituted) alkyl or alkoxy and X is an optionally substituted hydrocarbon chain, possibly interrupted by a carbocyclic or heterocyclic ring, or by one or more O atoms or CO groups. Such compositions are said to be useful for treating asthma and conditions generally for which antigen-antibody reactions are responsible.
