Term Description

Hair analysis provides a longer surveillance window for drug use than other methods because hair retains drugs longer (weeks or months, compared with days detectable in blood or urine). Collecting hair specimens also is less invasive than urine or blood sampling. Drawbacks for hair analysis include expense, and environmental contamination of the specimen. Tricyclic antidepressants tested for are: amitriptyline, nortriptyline, amoxapine, clomipramine, norclomipramine, désipramine, doxepine, imipramine, maprotiline, and trimipramine.

LP14735-2   Tricyclic antidepressants
Tricyclic antidepressants get their name from their three ringed molecular structure. The primary use of tricyclic antidepressants is to treat depression as well as neuralgic pain, chronic pain, and migraine prophylaxis. In children, tricyclic antidepressants are used to treat enuresis, obsessive-compulsive disorder, attention deficit hyperactivity disorder, school phobia, and separation anxiety. These drugs are are taken orally and are absorbed by the liver and then excreted through the kidneys. Tricyclic antidepressants block the absorption of neurotransmitters at nerve terminals, which makes the neurotransmitters more available in the brain.
