    摘要: Improving circulation, with minimal effect on blood pressure, using N-alkylated 1,4-dihydropyridines of the formula ##STR1## in which R.sup.1 represents hydrogen, nitro, cyano, trifluoromethyl, trifluoromethoxy, halogen or methyl,R.sup.2 represents hydrogen, halogen, nitro, hydroxyl, trifluoromethyl or methyl,R.sup.3 represents hydrogen or cyano, orR.sup.2 and R.sup.3 together form a fused benzo ring,R.sup.4 and R.sup.5 are identical or different and represent straight-chain or branched alkyl having up to 8 carbon atoms, which is optionally substituted by alkoxy having up to 4 carbon atoms, andR.sup.6 represents straight-chain or branched alkyl having up to 10 carbon atoms or represents cycloalkyl having 3 to 7 carbon atoms.Many of the compounds are new.
