Chemical Structure

Phenobarbital, also known by its brand names such as Luminal, is a barbiturate derivative. Its chemical formula is C12H12N2O3. The structure consists of a barbituric acid core, which is a six-membered ring containing nitrogen and oxygen atoms. This core is modified with phenyl and ethyl groups, contributing to its pharmacological properties.

Phenobarbital Mechanism of Action

Phenobarbital works by enhancing the activity of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits brain activity. By binding to the GABA receptor, Phenobarbital increases the flow of chloride ions into neurons, making them less excitable. This action helps to control seizures and produce a calming effect.
