Usage

Uses

1. Used in Medical Applications:
Phenobarbital sodium is used as an anticonvulsant and sedative-hypnotic for the treatment of various conditions such as seizures, anxiety, and insomnia. It helps in controlling the electrical activity in the brain, leading to a calming effect.
2. Used in Research and Laboratory Settings:
Phenobarbital sodium is used to anesthetize mice for inducing ischemia-reperfusion injury, which is a common procedure in medical research.
3. Used as a Positive Control in Bioluminescent Yeast Bioreporters (BLYAS) Assay:
Phenobarbital sodium is used as a positive control for the activation of the constitutive androstane receptor (CAR) in bioluminescent yeast bioreporters, which are used to study the effects of various compounds on gene expression.
4. Used in Pharmaceutical Industry:
Phenobarbital sodium is used under the brand name Luminal Sodium (Sterling Winthrop) in the pharmaceutical industry for the production of medications that target the central nervous system.

Air & Water Reactions

Hygroscopic. May be sensitive to prolonged exposure to air. Water soluble. Aqueous solutions are unstable, but may be kept at or below 50°F for a few days.

Reactivity Profile

Phenobarbital sodium can react with strong oxidizing agents. Incompatible with ammonium salts and chloral hydrate. Also incompatible with acids and acidic substances .

Fire Hazard

Flash point data for Phenobarbital sodium are not available; however, Phenobarbital sodium is probably combustible.

Biochem/physiol Actions

Phenobarbital, a substituted barbituric acid is an antileptic drug and is not easily eliminated from circulation. It hyperpolarizes the synaptic neuronal membranes by favoring the activation of neuronal postsynaptic GABAA?receptors by γ aminobutyric acid (GABA). Phenobarbital is also effective in treating neonatal seizures and status epilepticus.

Safety Profile

Confirmed carcinogen with experimental carcinogenic, neoplastigenic, tumorigenic, and teratogenic data. Poison by ingestion, intravenous, intraperitoneal, intraduodenal, and subcutaneous routes. Human systemic effects by ingestion: nausea or vomiting and coma. Experimental reproductive effects. Mutation data reported. Used to treat epilepsy, as a hypnotic and sedative. When heated to decomposition it emits toxic fumes of NOx and NazO. See also BARBITURATES
