The pharmacokinetics of amitriptyline in overdose have been reported not to fit conventional compartmental models. In this study, the dose-concentration-time relationships of amitriptyline in overdose were modeled with discriminant analysis, with an evolutionary heuristic search program, and with a decision-tree model based on the entropy of uncertainty of classification. The computer models al...
BACKGROUND Response and remission defined by cut-off values on the last observed depression severity score are commonly used as outcome criteria in clinical trials, but ignore the time course of symptomatic change and may lead to inefficient analyses. We explore alternative categorization of outcome by naturally occurring trajectories of symptom change. METHOD Growth mixture models were appli...
OBJECTIVE To study the efficacy and tolerability of amitriptyline and nortriptyline in a Brazilian population with fibromyalgia and to evaluate the instruments used to measure the efficacy of the treatment. METHODS A total of 118 fibromyalgia patients were randomly assigned to 3 groups: amitriptyline (AM, n = 40), nortriptyline (NOR, n =38) and placebo (PL, n = 40), and were blindly given 25 ...
We report a method for simultaneous measurement of five commonly used tricyclic antidepressant drugs (doxepin, desipramine, nortriptyline, imipramine, and amitriptyline) in serum by paired-ion high-performance liquid chromatography, with use of a reversed-phase column and ultraviolet detection at 254 nm. The drugs are extracted from 2 ml of serum at pH 14 into hexane/isoamyl alcohol (99/1 by vo...
BACKGROUND Osteoarthritis (OA) is a common cause of pain and disability. Currently available analgesics are often insufficiently effective or have unacceptable adverse effects. Tricyclic antidepressants may offer a useful centrally-acting analgesic. Nortriptyline is a readily-available, cheap and comparatively well-tolerated tricyclic antidepressant. METHODS/DESIGN We will conduct a parallel ...
Although the proportion of the adult population in the United States that smokes has decreased steadily, the rate of successful quit attempts is still low. Smokers develop nicotine dependence that resembles other addictions, and may require multiple attempts and long-term treatment to sustain abstinence. Currently available first-line agents for smoking cessation therapy include nicotine replac...
