Many commonly used pharmaceutical agents have been found to inhibit bacterial growth in vitro. Determinations of antimicrobial concentrations in sera of patients taking nonrecognized antibacterial agents could possibly be altered if bioassay systems are utilized for the determinations. We therefore attempted to determine the in vitro effect of commonly used drugs on bioassay indicator organisms...

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...

PURPOSE AND METHODS Cognitive behavior therapy (CBT) constitutes the basis of smoking cessation programs. Quitting rates are usually increased by the concomitant use of CBT and pharmacotherapy. There are studies showing the efficacy of bupropion and nortriptyline compared to placebo, but there is just one published comparison between these drugs, unfortunately with low power to detect significa...

The protective potential of nortriptyline has been reported in a few experimental models of brain ischemia, both in vivo and in vitro. However, the detailed molecular mechanisms of the protective action of the drug are still unresolved. The aim of the present study was to determine whether treatment with low or medium concentrations of nortriptyline (0.1-10 μM) might have an effect on cPLA₂ pro...

OBJECTIVE The authors examined the rate of response to the combination of nortriptyline and interpersonal psychotherapy for acute and continuation treatment of elderly patients with recurrent major depression. METHOD The subjects were 73 elderly patients, 61 of whom completed treatment. Nortriptyline steady-state blood levels were maintained at 80-120 ng/ml, and interpersonal psychotherapy wa...

The metabolism of nortriptyline was studied in vitro using cDNA-expressed human cytochrome P450 isozymes 1A2, 3A4, 2C19, and 2D6, CYP2D6 was the sole isozyme mediating hydroxylation of nortriptyline, the quantitatively most important metabolic pathway, and only (E)-10-OH-nortriptyline was formed. CYP2D6, 2C19, and 1A2, mentioned in decreasing order of significance, mediated the demethylation re...

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 a...

Corticosteroid insensitivity represents a major barrier to the treatment of chronic obstructive pulmonary disease (COPD) and severe asthma. It is caused by oxidative stress, leading to reduced histone deacetylase-2 (HDAC2) function through activation of phosphoinositide-3-kinase(PI3K ). The tricyclic antidepressant nortriptyline has been identified in high-throughput screens as an agent that in...

The Effect of Sertreline Versus Nortriptyline on Quality Life and Depression After Stroke:A Randomized Double-Blind Controlled Study

BACKGROUND Depression is a common psychiatric disorder worldwide, including in Iran, and is estimated to affect 10%-15% of the population. Antidepressant drugs can have multiple side effects, so a good choice of drug is important for successful treatment. This study compared the efficacy of nortriptyline with that of fluoxetine in the treatment of patients with major depressive disorder and ass...
