About

Phenobarbital is a barbiturate medication primarily used as an anticonvulsant for the long-term management of various seizure disorders, including generalized tonic-clonic and partial seizures. It works by enhancing the inhibitory effects of the neurotransmitter GABA in the central nervous system, leading to neuronal stabilization and a reduction in seizure activity. Phenobarbital also possesses sedative and hypnotic properties, which can be beneficial in some contexts but also contribute to its side effect profile.

Due to its potential for dependence, sedation, and significant drug interactions, phenobarbital is typically reserved for cases where newer antiepileptic drugs are ineffective or contraindicated, and its use requires careful monitoring of plasma levels and patient response.
