 Barbiturates produce a wide
spectrum of central nervous system depression, from mild sedation to coma, and
have been used as sedatives, hypnotics, anesthetics, and anticonvulsants.
Barbiturates are classified as ultrashort, short, intermediate, and
long-acting. These drugs are primarily used for insomnia and preoperative
sedation daytime sedation and the treatment of seizure disorders. Veterinarians
use pentobarbital, a long-acting barbiturate, for anesthesia and euthanasia.
Barbiturates are common drugs of abuse taken orally or intravenously.
They produce symptoms similar to intoxication. Chronic use will develop
tolerance, physical dependence and psychological dependence on barbiturates.
Overdoses can cause profound shock, coma, or death.
Shorter acting
barbiturates (Allobarbital, Alphenal, Amobarbital, Aprobarbital, Butabarbital,
Butalbital, Butethal, Pentobarbital, Secobarbital) can be detected for only 1
to 4 days, while long-acting barbiturates (Barbital, Phenobarbital) can be
detected for 2 to 3 weeks. Normally the suggested detection period for the
Barbiturates in urine is 4 to 7 days.
The DRUGCHECK® Drug of Abuse
Test yields a positive result when the Barbiturates (Secobarbital) in urine
exceed 300 ng/mL. |
