Hvorvidt virkningsmekanismen for AVONEX i MS sker via de samme kanaler som de biologiske virkninger, der er beskrevet herover, vides ikke, da patofysiologien for MS ikke er velbeskrevet.
Whether the mechanism of action of AVONEX in MS is mediated by the same pathway as the biological effects described above is not known because the pathophysiology of MS is not well established.
