tidepressants, a group of drugs widely used for treating depressive diseases. Its chemical structure is shown in Fig. 1. Most existing methods for the determination of nortriptyline in bulk, pharmaceutical formulations and biological samples have been reviewed. Among other methods described for the assay of this drug are direct UV-spectrophotometry, derivatives spectrophotometry, fluorimetry an...
Spectrophotometric and electrochemical studies were successfully used in quantitative analysis of Amitriptyline Hydrochloride (ATH) and Nortriptyline Hydrochloride (NTH). Conductometric titration were carried out in equeous solution using iodide and dopamine and serotonine as titrant. Two new methods using spectrophotometry are dascribed for the determination of (ATH) and (NTH) with potassium b...
A sensitive and specific HPLC method has been developed for the assay of amlodipine in human plasma. The assay involves derivatization with 4-chloro-7-nitrobenzofurazan (NBD-Cl), solid-phase extraction on a silica column and isocratic reversed-phase chromatography with fluorescence detection. Nortriptyline hydrochloride was used as an internal standard. The assay was linear over the concentrati...
We demonstrated the effect of nortriptyline, a tricyclic antidepressant drug and serotonin reuptake inhibitor, on voltage-dependent K+ (Kv) channels in freshly isolated rabbit coronary arterial smooth muscle cells using a whole-cell patch clamp technique. Nortriptyline inhibited Kv currents in a concentration-dependent manner, with an apparent IC50 value of 2.86±0.52 µM and a Hill coefficient o...
OBJECTIVE To test the efficacy of nortriptyline plus nicotine replacement therapy compared with placebo plus nicotine replacement therapy for smoking cessation. DESIGN Pragmatic randomised controlled trial. SETTING National Health Service stop smoking service clinics. PARTICIPANTS 901 people trying to stop smoking. INTERVENTIONS Participants chose their nicotine replacement product, inc...
background: the negative symptoms of schizophrenia remain a major clinical challenge. nortriptyline is a serotonin and noradrenalin reuptake inhibitor and belongs to secondary amine tricycles. the aim of this study is to evaluate the effect of nortriptyline on the negative symptoms of schizophrenia. methods: this study is a six-week randomized placebo-control trial of nortriptyline or placebo...
