Description and Uses

Primidone is chemically and structurally similar to phenobarbital with the exception that the carbonyl group on C2 is replaced by a methylene group. This modification leads to the production of a drug with strong anticonvulsant properties without expressed soporific effects.

Primidone is an Anticonvulsant.
