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...

CONTEXT Chronic tension-type headaches are characterized by near-daily headaches and often are difficult to manage in primary practice. Behavioral and pharmacological therapies each appear modestly effective, but data are lacking on their separate and combined effects. OBJECTIVE To evaluate the clinical efficacy of behavioral and pharmacological therapies, singly and combined, for chronic ten...

Despite the large number of elderly patients in nursing homes and the intensity of medication use there, few current data are available on patterns of medication use in this setting. We studied all medication use among 850 residents of 12 representative intermediate-care facilities in Massachusetts. Data on all prescriptions and patterns of actual use were recorded for all patients during one m...

PURPOSE To compare the effects of the antidepressant drugs duloxetine and amitriptyline on depressive behaviors in rats. METHODS Fifteen male Wistar rats were given systemic injections of duloxetine, amitriptyline or saline prior to a Forced Swimming Test (FST). Immobility and number of stops were measured. Data were analyzed by one-way ANOVA and Kruskall-Wallis. RESULTS Rats given injectio...

INTRODUCTION Melatonin has been studied in headache disorders. Amitriptyline is efficacious for migraine prevention, but its unfavourable side effect profile limits its use. METHODS A randomised, double-blind, placebo-controlled study was carried out. Men and women, aged 18-65 years, with migraine with or without aura, experiencing 2-8 attacks per month, were enrolled. After a 4-week baseline...

Cardiac toxicity is a frequent manifestation in amitriptyline overdose and is felt to be due, in part, to sodium channel blockade by the drug. Another agent with sodium channel blocking properties, diphenylhydantoin, has been used clinically to reverse cardiac conduction abnormalities induced by amitriptyline. This reversal of toxicity is believed to occur secondary to competition for the sodiu...

UNLABELLED We examined the effects of systemically administered gabapentin on flinching and biting/licking behaviors produced by 2.5% formalin in the rat, compared these with those of amitriptyline, and determined the effects of combinations of gabapentin with amitriptyline. Gabapentin produced a dose-related inhibition of Phase 2, but not Phase 1, flinching and biting/licking behaviors. In con...

AIMS Amitriptyline triggers the impairment of cognitive and motor functions and has been confirmed to have harmful effects on driving performance. Although interindividual differences in plasma concentration may cause variations in driving performance, the relationship between plasma amitriptyline concentration and its effect on driving performance has not been completely elucidated. Thus, the ...

Anti-inflammatory effects of antidepressants have been reported in some studies, but the mechanisms underlying these effects remain unknown. Amitriptyline, a tricyclic antidepressant, is widely used in the management of psychological disorders and various types of pain, including neuropathic pain or fibromyalgia. In our previous work, we found the role of supraspinal mechanisms in the anti-infl...

Amitriptyline is a classic tricyclic antidepressant (TCA) and has been used to treat the depression and anxiety of patients with cancer, but its relevance to cancer cell apoptosis is not known. In the present study, we demonstrated that amitriptyline inhibited cyclin D2 transactivation and displayed potential antimyeloma activity by inhibiting histone deacetylases (HDACs). Amitriptyline markedl...
