Although tricyclic antidepressant (TCA) blockade of cardiac Na+ channels is appreciated, actions on neuronal Na+ channels are less clear. Therefore, the effects of TCAs (amitriptyline, doxepin and desipramine) as well as trazdone and fluoxetine on voltage-gated Na+ current (INa) were examined in bovine adrenal chromaffin cells using the whole-cell patch-clamp method. Amitriptyline produced conc...

BACKGROUND In the present study, we examined clinical and laser-evoked potentials (LEP) features in two groups of chronic tension-type headache (CTTH) patients treated with two different approaches: intra-oral appliance of prosthesis, aiming to reduce muscular tenderness, and 10 mg daily amitriptyline. METHODS Eighteen patients with diagnosed CTTH participated in this open label, controlled s...

The cerebral pathology in a case of tricyclic antidepressant overdose by amitriptyline is described. A review of the literature of similar cases is summarized. The relation of the cerebral lesions to the development of a hypertensive episode possibly induced by amitriptyline is discussed.

Recently, both clinical and animal studies demonstrated neuronal and glial plasticity to be important for the therapeutic action of antidepressants. Antidepressants increase glial cell line-derived neurotrophic factor (GDNF) production through monoamine-independent protein-tyrosine kinase, extracellular signal-regulated kinase (ERK), and cAMP responsive element-binding protein (CREB) activation...

OBJECTIVE To compare three antidepressant drugs from different classes used in treating moderate-to-severe major depressive disorder (MDD) in Colombian adults. METHODS Based on expert input, a decision-tree model was adapted for Colombia to analyze data over 6 months from the government-payer perspective. The cost-effectiveness of amitriptyline, fluoxetine, and venlafaxine was determined. The...

Recently, both clinical and animal studies demonstrated neuronal and glial plasticity to be important for the therapeutic action of antidepressants. Antidepressants increase glial cell line-derived neurotrophic factor (GDNF) production through monoamine-independent protein tyrosine kinase (PTK), extracellular signal-regulated kinase (ERK) and cAMP responsive element binding protein (CREB) activ...

Recent studies show that neuronal and glial plasticity are important for therapeutic action of antidepressants. We previously reported that antidepressants increase glial cell line-derived neurotrophic factor (GDNF) production in rat C6 glioma cells (C6 cells). Here, we found that amitriptyline, a tricyclic antidepressant, increased both GDNF mRNA expression and release, which were selectively ...

OBJECTIVES Postural tremor is a regularly encountered side effect of amitriptyline which can be strong enough to cause discontinuation of therapy. The aim was to characterise amitriptyline induced tremor and to assess if the central or reflex component of physiological tremor was modulated by this drug. METHODS The postural hand tremor was measured in 15 patients on a clinical rating scale, b...

of amitriptyline is reported.The disease process was accompanied by noticeable loss of lung compliance, and a gross diffusion defect at alveolar level. It seems unlikely that the course was that of an aspiration or bronchopneumonia, and clinically and pathologically it resembled the changes seen in surfactant deficiency. It is suggested that amitriptyline in overdosage may interfere with the pr...

OBJECTIVE The aim of this experimental study was to investigate whether hypertonic saline or sodium bicarbonate administration prevented the development of cardiotoxicity in rats that received toxic doses of amitriptyline. METHOD Thirty-six Sprague Dawley rats were used in the study. The animals were divided into six groups. Group 1 received toxic doses of i.p. amitriptyline. Groups 2 and 3 t...
