<p>The use of dihydropyridine derivs. of formula (I) for treating asthma is new; where R1 = 6-10C aryl (opt. substd. by 1-3 of halo, CN, NO2, CF3, CF3O, up to 4C alkoxycarbonyl or alkoxy, COOH or 1-4C alkyl) or heteroaryl; R2 = 1-7C, opt. unsatd., linear, branched or cyclic alkyl, opt. interrupted by 1-2 O and/or S and opt. substd. by halo, NO2, CN, COOH, up to 4C alkoxycarbonyl, 6-10C aryl or NH2 (itself opt. substd. by 1 or 2 of 1-4C alkyl, 6-10C aryl or 7-10C aralkyl); R3 = 6-10C aryl (opt. substd. by 1-3 of halo, CN, NO2, CF3, CF3O, 1-4C alkoxy or dialkylamino) or 1-8C linear, branched or cyclic alkyl, opt. substd. by CN, halo or NO2.</p> |
