Barbiturates are commonly divided into groups based on the onset and duration of their action. The intermediate and short-acting barbiturates are the categories most commonly abused, most notably Seconal (secobarbital) and Tuinal (secobarbital with amobarbital). Long-acting barbiturates have an onset of action of 30 to 60 minutes and a duration of action of 6 to 8 hours.
Examples of long-acting barbiturates are phenobarbital and barbital. Their slow onset of action discourages their abuse.
The intermediate-acting barbiturates have an onset of action of 15 to 30 minutes and a duration of action of 4 to 6 hours.
Examples of intermediate-acting barbiturates are amobarbital, butabarbital, and Tuinal.
The short-acting barbiturates have an onset of action of 10 to 15 minutes and have a duration of action of 2 to 4 hours.
Examples of short-acting barbiturates are secobarbital and pentobarbital.
The ultra-short-acting barbiturates have an onset of action of 0 to 45 seconds and a duration of action 15 minutes to 3 hours. These are barbiturates used as anesthetics. Their effects are generally felt within one minute of intravenous administration.
Examples of ultra short-acting barbiturates are thiopenthal sodium, hexobarbital, and methohexital. The rapid onset and brief duration of action practically precludes the use of ultra-short-acting barbiturates in the street environment.
Concern about the addiction potential of barbiturates and the ever-increasing numbers of fatalities associated with them led to the development of alternative medications.
Barbiturates can be detected in urine drug testing from 2 to 10 days. Depending on usage.
