FDA godkänner första läkemedlet som angriper orsaken till narkolepsi

Den amerikanska läkemedelsmyndigheten FDA har godkänt en ny tablettbehandling som är den första att inrikta sig mot de bakomliggande orsakerna till narkolepsi typ 1.

Godkännandet gäller Orzeyful (oveporexton), som utvecklats av Takeda.

Narkolepsi typ 1 orsakas av en autoimmun reaktion som förstör de nervceller i hypotalamus som producerar orexin, ett signalämne som reglerar vakenhet och sömn. Följden kan bli sömnattacker, kataplexi – plötslig muskelsvaghet – hallucinationer, och sömnparalys.
