The present invention relates to novel N-aryloxyalkyl tryptamine .alpha..sub.1 -adrenergic receptor antagonists of the formula I: ##STR1## in which n is 2, 3 or 4; q is 1, 2 or 3; t is 0, 1, 2 or 3; z is 0, 1, 2 or 3; each R.sup.1 and R.sup.2 are independently hydroxy, halogen, cyano, (C.sub.1-8)alkyl, (C.sub.1-8)alkyloxy or trifluoromethyl; and R.sup.2 is hydrogen, (C.sub.1-4)alkyl, fluoro(C.sub.1-4)alkyl, difluoro(C.sub.1-4)alkyl, trifluoro(C.sub.1-4)alkyl, (C.sub.1-4)alkyloxy(C.sub.1-4)alkyl, oxo(C.sub.1-4)alkyl, (C.sub.1-8)cycloalkyl, (C.sub.1-8)cycloalkylmethyl or allyl or phenyl(C.sub.1-4)alkyl or heterocyclo(C.sub.1-8)alkyl (optionally substituted with one to two substituents independently selected from (C.sub.1-4)alkyl, (C.sub.1-4)alkyloxy, trifluoromethyl and halogen); R.sup.3 and R.sup.4 are independently hydrogen, (C.sub.1-4)alkyl, (C.sub.1-8)cycloalkyl, (C.sub.1-8)cycloalkylmethyl or allyl; and R.sup.5 is hydrogen, (C.sub.1-4)alkyl, (C.sub.1-8)cycloalkyl, (C.sub.1-8)cycloalkylmethyl, allyl, (C.sub.1-4)alkylsulfonyl and aminocarbonyl; with the proviso that when n is 2, t is 0, q is 1, z is 0, 1 or 2, R.sup.5 is hydrogen and R.sup.6 is hydroxy or (C.sub.1-8)alkyloxy then at least one of R.sup.3 and R.sup.4 is not hydrogen; and the pharmaceutically acceptable salts, individual isomers, and mixtures of isomers thereof; their uses as therapeutic agents and the methods of their making.
