Uses

 Butisol (125-40-6) has short duration of action compared to other barbiturates and a particularly fast onset of effects, which makes it useful for certain applications such as relieving anxiety before surgical procedures and treating severe insomnia; however, it is now rarely used because its relatively dangerous particularly when combined with alcohol, although it is still prescribed in South American countries and some Eastern European.

Safety Profile

Poison by ingestion, intravenous, intraperitoneal, and subcutaneous routes. A central nervous system depressant. When heated to decomposition it emits toxic fumes of NOx. See also BARBITURATES.

Specification

 Butisol (125-40-6) is a prescription barbiturate sleep aid, and also can be called Butabarbitone ; Secbutabarbital ; Secbubarbital ; Secbutobarbitone and butabarbital .Its intermediate duration of action gives butabarbital an abuse potential slightly lower than Secobarbital.It is also sold in combination with belladonna alkaloids under the brand name Butibel. This product contains a low dose of butabarbital combined with a standardised mix of belladonna alkaloids and is used as an antispasmodic taken to relieve cramping and spasms of the stomach and intestines. They have been used to decrease the amount of acid formed in the stomach. Another similar product is Donnatal , which contains belladonna alkaloids combined with phenobarbital.
