The present invention relates to novel N-aryloxyalkyl tryptamine . alpha. 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 1 and R 2 are independently hydroxy, halogen, cyano, (C 1-8)alkyl, (C 1-8)alkyloxy or trifluoromethyl; and R 2 is hydrogen, (C 1-4)alkyl, fluoro(C 1-4)alkyl, difluoro(C 1-4) alkyl, trifluoro(C 1-4)alkyl, (C 1-4) alkyloxy(C 1-4)alkyl, oxo(C 1-4)alkyl, (C 1-8)cycloalkyl, (C. sub.1-8)cycloalkylmethyl or allyl or phenyl(C 1-4)alkyl or heterocyclo(C 1-8)alkyl (optionally substituted with one to two substituents independently selected from (C 1-4)alkyl, (C 1-4) alkyloxy, trifluoromethyl and halogen); R. sup.3 and R 4 are independently hydrogen, (C 1-4) alkyl, (C 1-8)cycloalkyl, (C 1-8)cycloalkylmethyl or allyl; and R. sup. 5 is hydrogen, (C 1-4)alkyl, (C 1-8)cycloalkyl, (C 1-8) cycloalkylmethyl, allyl, (C 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 5 is hydrogen and R 6 is hydroxy or (C 1-8)alkyloxy then at least one of R 3 and R 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.
