What does amytal mean?
Amytal is the proprietary trade name for amobarbital, a barbiturate introduced in the early twentieth century and widely used as a sedative and hypnotic. Like other barbiturates, it depresses the central nervous system, producing drowsiness, relief of anxiety, and sleep at appropriate doses. The drug was commonly dispensed as tablets for insomnia and, in its soluble sodium salt form known as sodium Amytal, given by injection. That injectable form gained particular notoriety in mid-century psychiatry, where 'Amytal interviews' were used to encourage patients to surface repressed memories, earning the drug a popular reputation as a 'truth serum' — a reputation its unreliable results never fully justified. As safer alternatives such as benzodiazepines emerged, barbiturates including Amytal fell out of routine medical use, and the word now appears chiefly in medical literature, accounts of twentieth-century psychiatry, and discussions of controlled substances. It remains a recognizable example of how a brand name can become shorthand for an entire class of drugs.
nounA proprietary name for amobarbital, a barbiturate drug used as a sedative and hypnotic to induce sleep and calm anxiety.
- As a trademarked pharmaceutical name: the barbiturate amobarbital, prescribed as a short-acting sedative and hypnotic.
- By extension, the term is associated with 'sodium Amytal', an injectable form historically used in psychiatric 'narcosynthesis' and popularly dubbed a truth serum.
"The physician prescribed a small dose of Amytal to help the patient sleep before the procedure."
"The anaesthetist administered sodium Amytal to induce a calm, sleep-like state before the examination."
"Mid-century psychiatrists sometimes used Amytal interviews to help patients recall traumatic memories, though the technique later fell out of favour."
As a branded drug name, Amytal is normally treated as a mass noun referring to the substance; a plural form would only appear informally when counting individual tablets or doses.
"The old prescription bottle still held two Amytals from decades past."
In the mid-20th century, psychiatrists used injections of sodium Amytal — the so-called 'truth serum' — believing it could unlock repressed memories; the results proved far less reliable than the movies suggested.

Etymology of amytal
Amytal was coined as a commercial brand name by the American pharmaceutical firm Eli Lilly, combining 'amyl' — the five-carbon alkyl group derived from the Greek 'amylon' (starch), which also gives us 'amylase' and 'amyloid' — with '-tal', a suffix borrowed from the earlier barbiturate name Barbital. The name thus encodes the drug's chemistry: amobarbital contains an amyl group attached to the barbituric acid core. It entered use in the 1920s and became especially familiar through its sodium salt, sodium Amytal.
How amytal is actually used
Amytal is a proprietary (brand) name rather than a common dictionary word, so it appears mainly in medical, pharmacological, and historical contexts. In modern clinical writing the generic name amobarbital is preferred; the capitalized form 'Amytal' signals its status as a trademark. Because barbiturates are now largely superseded by safer drugs, references today are often historical.
Easily confused with amytal
Amobarbital is the generic drug name, while Amytal is the original brand name under which that same drug was marketed.
Amyl refers to the five-carbon chemical group whose name partly forms 'Amytal'; it is not itself a drug.
