Also used in ammunition, but has declining use in paints, plumbing equipment and cable coverings because of its toxicity.
ChemistryCommon MedicalFbi filesGovernmental & MilitaryOrdnance SurveySciencePhenobarbital, a long-acting barbiturate, is a medication primarily used to treat seizures, including those associated with epilepsy. It works by depressing the central nervous system, leading to a sedative effect that can prevent the occurrence of seizures. Phenobarbital is also used as a sedative before surgeries and to relieve anxiety or insomnia, although its use for these purposes has declined with the development of safer alternatives. Despite its effectiveness, phenobarbital has a high potential for dependence and abuse, requiring careful management under medical supervision.
The drug's mechanism involves enhancing the action of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter in the brain, thereby reducing neuronal excitability. Phenobarbital's long half-life allows for once-daily dosing in the management of chronic conditions, but it also contributes to the risk of accumulation and toxicity. Monitoring of blood levels is essential to ensure therapeutic efficacy while minimizing adverse effects, such as drowsiness, confusion, and respiratory depression, especially in vulnerable populations like the elderly and those with liver impairment.
