(EN) The present invention relates to therapeutically active azabicyclic compounds of formula (I) or the quaternized form thereof, a method of preparing the same and to pharmaceutical or veterinary compositions comprising the compounds. The novel compounds are useful in treating a disease in the central nervous system caused by malfunctioning of the muscarinic cholinergic system.(FR) L'invention concerne des composés azabicycliques de formule (I), actifs sur le plan thérapeutiques, ou la forme quaternarisée de ceux-ci. Elle porte aussi sur un procédé de préparation desdits composée et de compositions pharmaceutiques ou vétérinaires comprenant les composés. Ces nouveaux composés sont utiles dans le traitement d'une maladie localisée dans le système nerveux central et induite par un dysfonctionnement du système cholinergique et muscarinique.
