Dysesthetic pain following traumatic myelopathy is characterized by diffuse burning and tingling sensations distal to the level of spinal injury. The dysesthetic pain syndrome (DPS) can compromise performance of functional abilities and inhibit participation in rehabilitation programs. Recent laboratory evidence suggests that antidepressant medications with selective inhibition of serotonin reu...

Hypothesis: Common amphiphilic drug molecules often have a more rigid nonpolar part than conventional surfactants. The rigidity is expected to influence the self-assembling properties and possibly give rise aggregation patterns different from that of regular Experiments: We investigated hydrochloride salts adiphenine (ADP), pavatrine (PVT), amitriptyline (AMT) at concentrations up 50 wt% using ...

Neurotrophins, the cognate ligands for the Trk receptors, are homodimers and induce Trk dimerization through a symmetric bivalent mechanism. We report here that amitriptyline, an antidepressant drug, directly binds TrkA and TrkB and triggers their dimerization and activation. Amitriptyline, but not any other tricyclic or selective serotonin reuptake inhibitor antidepressants, promotes TrkA auto...

BACKGROUND This study explores the underlying mechanism of the antiinflammatory effect of amitriptyline in chronic morphine-infused rats. METHODS Male Wistar rats were implanted with two intrathecal catheters. One catheter was for the continuous infusion of saline, amitriptyline (15 microg/h), morphine (15 microg/h), p38 mitogen-activated protein kinase inhibitor SB203580 (0.5 microg/h), morp...

BACKGROUND Amitriptyline is an important cause of mortality due to its cardiovascular toxicity. AIMS To investigate the changes in levels of cardiac S100b protein on amitriptyline-induced cardiotoxicity and also to examine the correlation between amitriptyline-induced cardiotoxic effects and cardiac S100b protein in an isolated rat heart model. STUDY DESIGN Animal experimentation, isolated ...

OBJECTIVE The present study was designed to further investigate the effect of amitriptyline, a classical tricyclic antidepressant, on carrageenan-induced paw edema in rats. METHODS First, amitriptyline was administered intraperitoneally (i.p.) at doses of 20, 40 and 80 mg kg-1, 30 min before subplantar injection of carrageenan. Second, amitriptyline was given intracerebroventriculary or intra...

The objective of this study was to assess the efficacy and safety of amitriptyline as a treatment of FM. A comprehensive computerized search in Medline (Pubmed), EMBASE and The Cochrane Library was performed. Randomized controlled trials (RCTs) comparing amitriptyline vs placebo in adult patients suffering from FM were identified, the methodological quality was assessed and the results of the m...

Depressive disorders are more common among persons with chronic diseases such as inflammatory bowel disease and anti-inflammatory effect of some antidepressants such as amitriptyline has been reported. Acetic acid colitis was induced in both reserpinised (depressed) and non-reserpinised (normal) rats. Reserpinised groups received reserpine (6 mg/kg, i.p.) one hour prior to colitis induction. Th...

A novel electrochemical sensor was proposed for the determination of amitriptyline based on the copper oxide (CuO) nanoparticles modified graphite screen-printed electrode. CuO nanoparticles were used to enhance the surface area of the electrode and then improve the sensitivity of the electrochemical sensor. Amitriptyline electrochemical response characteristics of the modified electrode in a p...
