Date Mar. 2, 1995The present invention relates to the iontophoretic delivery to a patient, more in particular to a migraine patient, of a compound of formula (I) as shown hereinunder. The invention also relates to a device for the iontophoretic delivery of a compound of formula (I), as well as to a composition containing a compound of formula (I), which can be applied in a device for iontophoretic delivery. Said compounds are benzopyranalkylaminoalkyl substituted guanidines having the formula <IMAGE> (I) the pharmaceutically acceptable acid addition salts thereof, and the stereochemically isomeric forms thereof, wherein R1 is hydrogen or C1-6alkyl; R2 is hydrogen, C1-6alkyl, C3-6alkenyl or C3-6alkynyl; R3 is hydrogen or C1-6alkyl; or R2 and R3 taken together form a bivalent radical of formula -(CH2)m- wherein m is 4 or 5; or R1 and R2 taken together form a bivalent radical of formula -CH=CH- or of formula -(CH2)n-, wherein n is 2, 3 or 4; or R3 may represent a bond when R1 and R2 taken together form a bivalent radical of formula -CH=CH-CH=; R4 and R5 each independently are hydrogen or C1-6alkyl; Alk1 is a bivalent C1-3alkanediyl radical; Alk2 is a bivalent C2-15alkanediyl radical; and R6 and R7 each independently are hydrogen, halo, C1-6alkyl, C3-6alkenyl, C3-6alkynyl, hydroxy, C1-6alkyloxy or cyano. |
