Pentothal
Pentothal is an intravenous anesthetic, considered a member of the short acting barbiturates (Pentothal, Brevital, and Surital.) Pentothal was the first short acting and is the prototype for all others. Ernest Volwiler and Donalee Tabern came up with Pentothal (1936) when they were seeking an anesthetic which could be injected directly into the bloodstream.
