<unk> , also known as<unk>  Pentothal (a trademark of Abbott Laboratories),<unk> , thiopentone, or Trapanal (also a trademark), is a rapid-onset short-acting barbiturate general anesthetic. It is the thiobarbiturate analog of pentobarbital, and an analog of thiobarbital.<unk>  was a core medicine in the World Health Organization's List of Essential Medicines, but was supplanted by propofol. Despite this,<unk>  is listed as an acceptable alternative to propofol, depending on local availability and cost of these agents. It was previously the first of three drugs administered during most lethal injections in the United States, but the US manufacturer Hospira stopped manufacturing the drug and the European Union banned the export of the drug for this purpose. Although<unk>  abuse carries a dependency risk, its recreational use is rare.
