Abstract
The invention relates to 3-aminopyridazine derivatives. These compounds have the formula ##STR1## in which: R.sub.V is a linear or branched C.sub.1 -C.sub.4 alkyl group; PA0 R.sub.6 is hydrogen, a C.sub.1 -C.sub.3 alkoxy or a hydroxyl group; and PA0 Z is a group ##STR2## in which: n.sub.1 and n.sub.2 independently are zero or one, PA1 Y.sub.1 and Y.sub.2 independently are hydrogen or a C.sub.1 -C.sub.3 alkyl group, and PA1 T is a dialkylamino group in which the alkyls are C.sub.1 -C.sub.3, if Y.sub.1 or Y.sub.2 is other than hydrogen, or T is a heterocycle selected from: ##STR3## Application: drugs active on the central nervous system.
