Effects of Amitriptyline for the Treatment of Pain on Driving Performance and Cognition.

2014-07-24 14:27:34 | BioPortfolio


The acute and subchronic effects of amitriptyline were compared to placebo in a double-blind crossover randomized study on driving ability and driving-related skills in chronic neuropathic pain patients.It was hypothesized that nocturnally administered 25 mg amitriptyline might affect driving performance negatively after acute, but not after subchronic treatment.


The present study was designed to determine the effects of nocturnally administered 25 mg amitriptyline, compared to placebo, after single (Day 1, acute effects) and repeated (Day 15, subchronic effects) administration on driving performance in neuropathic pain patients. In addition to the on-the-road driving test, laboratory tests measuring driving-related skills were administered. Moreover, effects of amitriptlyine on an attentional capacity task were tested using Event-Related Potentials (ERPs). It was hypothesized that nocturnally administered 25 mg amitriptyline might affect driving performance negatively after acute, but not after subchronic treatment.

Medical and Biotech [MESH] Definitions

A widely distributed purinergic P2X receptor subtype that plays a role in pain sensation. P2X4 receptors found on MICROGLIA cells may also play a role in the mediation of allodynia-related NEUROPATHIC PAIN.

Tricyclic antidepressant with anticholinergic and sedative properties. It appears to prevent the re-uptake of norepinephrine and serotonin at nerve terminals, thus potentiating the action of these neurotransmitters. Amitriptyline also appears to antagonize cholinergic and alpha-1 adrenergic responses to bioactive amines.

Acute or chronic pain in the lumbar or sacral regions, which may be associated with musculo-ligamentous SPRAINS AND STRAINS; INTERVERTEBRAL DISK DISPLACEMENT; and other conditions.

Facilities providing diagnostic, therapeutic, and palliative services for patients with severe chronic pain. These may be free-standing clinics or hospital-based and serve ambulatory or inpatient populations. The approach is usually multidisciplinary. These clinics are often referred to as "acute pain services". (From Br Med Bull 1991 Jul;47(3):762-85)

Acute or chronic pain located in the posterior regions of the THORAX; LUMBOSACRAL REGION; or the adjacent regions.
