Substituted dihydropyranopyridines of the general formula I, wherein = a is a divalent radical = N- CH = CH-CH =, CH-N = CH-CH =, = CH-CH = N-CH = or = CH-CH = CH-N =, wherein one or two H are optionally substituted by halogen in these divalent radicals , hydroxy, alkyl of 1 to 6 C or alkoxy of 1 to 6 C; R.sup.1.n., R.sup.2.n. and R.sup.3.n. each independently is H or alkyl of 1 to 6 C; Alk.sup.1.n. is alkanediyl having 1 to 5 C; Alk.sup.2.n. is alkanediyl having 2 to 15 C; Q is a five- or six-membered heterocyclic radical containing at least one nitrogen atom or aa; where R.sup.4.n. is H, cyano, aminocarbonyl or alkyl of 1 to 6 C; R.sup.5.n. is H, alkyl of 1-6C, alkenyl of 3-6C or alkynyl of 3-6C; R.sup.6.n. is H or alkyl of 1 to 6 C; or R.sup.5.n. and R.sup.6.n. together form a divalent radical of the formula - (CH.sub.2.n.sub.4) - or - (CH.sub.2.sub.2.sub.3), and pharmaceutically acceptable addition thereof. acid salts, N-oxides and stereochemically isomeric phr |
