Nembutal (pentobarbital) belongs to the barbiturates class of drugs.
Barbiturates are central nervous system depressants that are also known as sedative-hypnotic drugs because, at low doses, they help to initiate sleep (sedative effects), and at higher doses, they can treat anxiety issues (hypnotic effects).
The main applications of Nembutal are as a short-term treatment for insomnia (most commonly used to help people fall asleep but not as effective in helping people stay asleep), anxiety treatment, as an anticonvulsant in emergency situations, and as a preanesthetic prior to surgery. The drug has also been used as a euthanasia drug for both animals and humans, including use in state executions of criminals. Any drug that can be used to euthanize animals or humans is obviously dangerous in large doses.
Slow and slurred speech; problems with motor coordination; a shuffling or staggering gate; problems with balance; decreases in breathing rate, heart rate, blood pressure, and body temperature; slowed rate of thought; problems with reasoning and logic; aggression; sedation and lethargy; and unconsciousness and/or coma are all symptoms of alcohol intoxication.
