The invention relates to derivatives of 2,3-dihydro 3-imino-pyridazine responding to general formula: ##STR1## in which: A represents an atom of oxygen or of sulfur; R.sub.1 represents a lower alkyl group, or an aromatic group selected from: the phenyl group; the phenyl groups mono- or poly-substituted by a halogen group, a lower alkyl group, a lower alkoxy group, a nitro group, a hydroxy or methylenedioxy group; the naphthyl group; the furyl group; the thienyl group or the pyridyl group; R.sub.2 and R.sub.3 each designate independently hydrogen or a lower alkyl group; a phenyl group, or R.sub.2 and R.sub.3, taken together, constitute, with the 2 atoms of the pyridazinic cycle to which they are bonded, a benzene ring, and their pharmaceutically acceptable salts. Application: antidepressants or psychotonics.
