The present invention relates to the compounds of formula ##STR1## in which X.sub.1 represents N or ##STR2## X.sub.2 represents N or ##STR3## provided that X.sub.1 and X.sub.2 are different from each other; R.sub.1 and R.sub.2 being --(CH.sub.2).sub.n OH wherein n is 1 to 4 or ##STR4## represents a saturated heterocycle with 5 or 6 groupings containing one nitrogen atom as heteroatom, substituted in 3 or 4 position for example by (CH.sub.2).sub.m OR.sub.6 where R.sub.6 is H or an acyl radical or an amido radical; to a process for preparing said compounds; and to the drugs containing said compounds active in particular on the central nervous system.

the compounds with a phenyl ring in the 6-position of the pyridazine ring exhibited appreciable anticonvulsant activity. Furthermore, a 4-hydroxypiperidine side chain in the 3-position of the pyridazine ring appeared essential for anticonvulsant activity. Substituting the phenyl ring with a Cl in the 2-position led to a substantial increase of activity; disubstituting the phenyl ring with a Cl in the
