摘要:
The invention relates to the use of 5-alkylpyridazine derivatives of the formula ##STR1## in which R.sub.1 is a C.sub.1 -C.sub.4 alkyl group or a phenyl group and R.sub.2 and R.sub.3 independently are a C.sub.1 -C.sub.4 alkyl group, or R.sub.2 and R.sub.3, taken with the nitrogen atom to which they are bonded, form a morpholino group, or one of their pharmaceutically acceptable salts, for the preparation of pharmaceutical compositions for combating pathological conditions associated with a cortical cholinergic deficiency, especially for the treatment of degenerative syndromes associated with senescence.
