To study correlations between the concentrations, in serum, of amitriptyline and its most important metabolites with clinical response in patients, we developed a "high-performance" liquid-chromatographic method for routine determination of amitriptyline, nortriptyline, total 10-hydroxy-amitriptyline, desmethylnortriptyline, and E(trans)- and Z(cis)-10-hydroxynortriptyline. These compounds are ...

BACKGROUND Neuropathy is a common adverse effect of chemotherapy. The tricyclic antidepressant, amitriptyline, is a gold standard in the treatment of neuropathic pain. This double-blind, randomized placebo-controlled trial assessed the efficacy of amitriptyline to prevent chemotherapy-induced neuropathic symptoms. PATIENTS AND METHODS Patients without previous neuropathy, who started chemothe...

The aim of this study was to evaluate the anti-nociceptive effects of a low, sub-effective dose of amitriptyline, in combination with the different doses of ethanolic and aqueous extracts of Crocus sativus following sciatic nerve chronic constriction injury (CCI) in rats. Amitriptyline (3, 10 and 30 mg/kg, i.p.) and the extracts (25, 50 and 100 mg/kg, i.p.), were separately administered at the ...

OBJECTIVE This study was done to compare the effects of 6-week treatment with amitriptyline on hypothalamic-pituitary-adrenocortical (HPA) regulation in elderly depressed patients and age-matched comparison subjects. METHOD A combined dexamethasone-suppression/CRH-stimulation (dexamethasone/CRH) test was administered before initiation of amitriptyline treatment and at the end of weeks 1, 3, a...

BACKGROUND Amitriptyline is effective in relieving neuropathic pain. Its site of action is thought to be supraspinal and spinal, but a peripheral effect on fibers is also suggested. METHODS This double-blind study examined the effects of transcutaneous amitriptyline diluted in hydroalcoholic solution in healthy young male volunteers. Six treatments were randomly applied on different areas of ...

In Experiment 1, the effect of the administration of the antidepressant amitriptyline (30 mg/kg) for 21 days on the acquisition and consolidation of the inhibitory avoidance task was studied in male and female mice. In Experiment 2, it was evaluated whether amitriptyline administered after the consolidation of this task would block the memory retrieval. Anxiety and spontaneous activity in the e...

Selective serotonine reuptake inhibitors (SSRI) are believed to be less dangerous in the treatment of depressive disorder in comparison with tricyclic antidepressants (TCA) due to their relative lack of cardiotoxicity. Thus, we investigated the effect of citalopram (SSRI) on membrane electrophysiology in rat cardiomyocytes in tissue culture. The results were compared with those from amitriptyli...

The metamorphic response of pediveliger larvae of Mytilus galloprovincialis to the neurotransmitter blockers chlorpromazine, amitriptyline, rauwolscine, idazoxan, atenolol and butoxamine, and to tetraethylammonium chloride (TEA) was investigated through a series of bioassays. Chlorpromazine, amitriptyline and idazoxin inhibited larval metamorphosis induced by 10⁻⁴ M epinephrine. The concentrati...

The simple, accurate and precise absorption ratio method has been developed for the simultaneous estimation of amitriptyline HCl and perphenazine in combined tablet dosage form. The λmax of amitriptyline HCl and perphenazine were found to be 240.0 nm and 258.0 nm respectively. For the estimation by Q-analysis method, the λmax those selected were 240.0 nm and an isoabsorptive point for both the ...
