Abstract

The invention relates to a perampanel freeze-dried oral disintegrating tablet and a preparation method thereof. The perampanel freeze-dried oral disintegrating tablet comprises, by weight, 1-20 parts of a framework propping agent, 1-50 parts of an adhesive, 0.1-8 parts of a freeze drying protection agent and 2-12 parts of perampanel. The perampanel freeze-dried oral disintegrating tablet is convenient for patients to take and improves the medicine taking compliance of epilepsy patients, and the preparation method has the advantages of simplicity and short time.

Description

technical field [0001] The invention relates to the field of oral preparations, in particular to perampanel orally disintegrating tablets and a preparation method thereof, more specifically to perampanel freeze-dried orally disintegrating tablets and a preparation method thereof. Background technique [0002] Partial seizures are also called focal epileptic seizures. The initial clinical and EEG changes suggest that some neurons in the cerebral hemisphere are first activated, followed by synchronous rapid discharges, which rapidly spread to the surrounding normal brain areas, resulting in a series of electrophysiological and neurological disorders. Neurochemical changes leading to neuronal energy depletion and decreased metabolism automatically terminate seizures. [0003] Perampanel is a noncompetitive amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA) glutamate receptor antagonist indicated for the treatment of 12-year-olds and 12-year-olds patients with partial-o...
