Hazard Information

General Description

Odorless white crystalline powder. Aqueous solutions are alkaline to litmus and phenolphthalein (pH approximately 9.3). Bitter taste. A narcotic.

Reactivity Profile

SODIUM PHENOBARBITAL(57-30-7) can react with strong oxidizing agents. Incompatible with ammonium salts and chloral hydrate. Also incompatible with acids and acidic substances .

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.

Fire Hazard

Flash point data for this chemical are not available; however, SODIUM PHENOBARBITAL is probably combustible.

Chemical Properties

Solution S is clear (2.2.1) and not more intensely coloured than reference solution Y7 (2.2.2, Method II).

Uses

Anticonvulsant; sedative-hypnotic.

Definition

ChEBI: A barbiturate that is the sodium salt of phenobarbital (barbituric acid substituted at C-5 by ethyl and phenyl groups).

Brand name

Luminal Sodium (Sterling Winthrop).

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.
