🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by slowing down abnormal electrical signals in the brain. Primidone itself is active, and it is also converted in the body into phenobarbital and phenylethylmalonamide, both of which contribute to seizure control. These substances enhance the effect of GABA, a natural calming chemical in the brain, which reduces the spread of seizure activity.
