Description: Pentobarbital (US English) or pentobarbitone (UK English) is a short-acting barbiturate that was first synthesized in 1928. Pentobarbital can occur as both a free acid and salts such as sodium and calcium. The free acid is only slightly soluble in water and ethanol.

One brand name for this drug is Nembutal, coined by Dr. John S. Lundy, who started using it in 1930, from the structural formula of the sodium salt—Na (sodium) + ethyl + methyl + butyl + al (common suffix for barbiturates).

The drug is owned and manufactured by the Danish pharmaceutical company Lundbeck. In the United States, the drug has been used for executions of humans, but this usage is forbidden by the owner and manufacturer of the drug, that refuses to sell it to customers likely to use it for this purpose, in accordance with Danish law and European human rights law that forbid the death penalty.
