How it works

From the US prescribing label for the same active substance (PERAMPANEL). It describes the substance, not this exact product.

Perampanel is a non-competitive antagonist of the ionotropic α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) glutamate receptor on post-synaptic neurons.

Glutamate is the primary excitatory neurotransmitter in the central nervous system and is implicated in a number of neurological disorders caused by neuronal over excitation.

The shape is a standard model drawn from the two times above, not a measurement. How fast a medicine acts and wears off also depends on the dose, the form and the person.
How the body breaks it down

Perampanel is extensively metabolized via primary oxidation and sequential glucuronidation.

With food

Co-administration of perampanel tablet with a high fat meal had no impact on the total exposure (AUC 0 to inf ) of perampanel and reduced the peak plasma concentration (C max ) of perampanel by 11% to 40%.
