This invention relates to a method of treating disorders responsive to the blockade of sodium ion channels using novel 2-substituted bicyclic benzoheterocyclic compounds of Formula I, or a pharmaceutically-acceptable salt or solvate thereof, wherein X is -NH-, -N= or -S-, Y is oxygen or sulfur, and n, p, R1, R2, R3 and R4 are defined in the specification. The invention is also directed to the use of compounds of Formula I for the treatment of neuronal damage following global or focal ischemia, for the treatment or prevention of neurodegenerative conditions such as amyotrophic lateral sclerosis (ALS), and for the treatment, prevention or amelioration of acute or chronic pain, neuropathic pain or surgical pain, as antitinnitus agents, as anticonvulsants, and as antimanic depressants, as local anesthetics, as antiarrhythmics and for the treatment or prevention of diabetic neuropathy.

La présente invention concerne un procédé de traitement de troubles sensibles au blocage de canaux sodiques à l'aide de composés benzohétérocycliques bicycliques substitués en 2 de formule I, un sel pharmaceutiquement acceptable ou un solvate. Dans la formule I, X représente -NH-, -N=; ou -S-, Y représente oxygène ou soufre, et n, p, R¿1?, R¿2?, R¿3? et R¿4? sont tels que définis dans la description. L'invention concerne également l'utilisation de composés de formule I pour le traitement de lésions neuronales consécutives à une ischémie générale ou focale, pour le traitement ou la prévention de maladies neurodégénératives telles que la sclérose latérale amyotrophique (ALS), et pour le traitement, la prévention ou l'atténuation de la douleur aiguë ou chronique, de la douleur neuropathique ou de la douleur chirurgicale, en tant qu'agents anti-acouphènes, en tant qu'anticonvulsivants, et antidépresseurs antimaniaques, en tant qu'anesthésiques locaux, en tant qu'antiarhythmiques et pour le traitement ou la prévention de la neuropathie diabétique.
