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, or R.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, and R.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.
