Our case shows that improvement of severe cognitive impairment in individual cases is possible. In our opinion, this underlines the necessity of a careful re-evaluation of the patient's symptoms at presentation and the course of the disease as well as a critical review of the prescribed medications.
Although tricyclic antidepressants (TCAs) have gained wide acceptance for use in the treatment of depression in pregnant women, their pharmacokinetics during pregnancy have been poorly characterized. The aim of the present study was to investigate the transplacental transfer of amitriptyline (AMI) and its main active metabolite nortriptyline (NOR) in isolated perfused human placenta.

These results suggest that nortriptyline is associated with significant symptomatic improvement in all areas of bereavement-related depression except continued intensity of grief after a median treatment interval of 6.4 weeks. This study indicates the need for a controlled clinical trial to determine the placebo response rate, the relapse rate after discontinuation of medication, and the value of combination therapy (using both pharmacotherapy and psychotherapy).

HPLC columns packed with 3 microm particle size HPLC Technology Techsphere SCX (propylsulfonic acid-modified) silica offer considerable advantages over 5 microm SCX packings in the analysis of basic drugs using 100% methanol eluents containing an ionic modifier such as ammonium perchlorate. The basic drugs studied included clozapine and norclozapine, olanzapine, quinine and quinidine, and amitriptyline, nortriptyline, imipramine and desipramine. The 3 microm column was not only more efficient for a given column length compared with 5 microm materials, but also elution times were less, a phenomenon observed in reversed-phase systems. The high efficiencies and excellent peak shapes obtained with the 3 microm SCX-modified packing together with the relatively low back-pressures attained show that such materials deserve serious consideration by laboratories involved in the analysis of basic drugs. Manufacturers should offer such packings as a matter of routine. Alternative ionic modifiers such as ammonium acetate are available for use with mass spectrometric detection if required.

First-line neuropathic pain drugs, including tricyclic antidepressants, are not always effective, and opioids have been recommended as second line. This trial evaluates a nortriptyline-morphine combination, compared with each monotherapy. In this randomized, double-blind crossover trial, patients with neuropathic pain were enrolled at 1 site between January 25, 2010, and May 22, 2014, and randomized in a 1:1:1 ratio using a balanced Latin square design to receive oral nortriptyline, morphine, and their combination. During each of three 6-week periods, doses were titrated toward maximal tolerated dose (MTD). The primary outcome was average daily pain at MTD, and secondary outcomes included other pain, mood and quality of life measures, and adverse effects. Sixty-two patients were screened, 52 enrolled, and 39 completed at least 2 treatment periods. Average daily pain (0-10) at baseline was 5.3 and at MTD was 2.6 for combination vs 3.1 for nortriptyline (P = 0.046) and 3.4 for morphine (P = 0.002). Brief Pain Inventory scores for average and present pain were also significantly lower for combination vs each monotherapy. Combination treatment resulted in moderate-severe constipation in 43% vs 46% with morphine (P = 0.82) and 5% with nortriptyline (P < 0.0001). Combination treatment resulted in moderate-severe dry mouth in 58% vs 49% with nortriptyline (P = 0.84) and 13% with morphine (P < 0.0001). This trial suggests superior efficacy of a nortriptyline-morphine combination over either monotherapy with constipation, dry mouth, and somnolence as the most frequent adverse effects.
Patients with major depressive disorder (MDD) may have significant differences in cholesterol levels compared with healthy controls. A previous study by our group reported that depressed patients with elevated cholesterol levels (>or=200 mg/dl) were significantly more likely to be nonresponders to fluoxetine treatment than depressed patients with nonelevated cholesterol levels. However, very little is known regarding cholesterol in patients with treatment-resistant depression (TRD). The purpose of this study was to compare cholesterol levels at baseline between depressed patients with and without TRD and to test whether cholesterol levels at baseline can predict clinical response in patients with TRD treated with open-label nortriptyline (NT).
The chromatographic behavior of protonated amines in reversed-phase liquid chromatography (RPLC) is influenced markedly by the identity of the mobile-phase anion. For example, retention factor values, k, obtained from protonated nordoxepin, nortriptyline, and amitriptyline increase almost 1 order of magnitude across the following series of anions employed as mobile-phase modifiers: H2PO4- < HCOO- < CH3SO3- < Cl- < NO3- < CF3COO- < BF4- < ClO4- < PF6-. Early eluting primary, secondary, and tertiary benzylamines are retained and resolved using BF4-, ClO4-, and PF6- but elute in or very near the void using all other mobile-phase anions tested. In contrast, a neutral hydrophobic marker, acenaphthene, shows no significant changes in retention with mobile-phase anion identity. Such large differences in amine retention with anion identity can be rationalized via both an ion-pairing model and the Hofmeister effect. Two key findings are reported. First, the dependence of amine retention on mobile-phase anion identity is attributed unambiguously to the Hofmeister effect and is quantified using a simple equation based solely on differences in the solvation of anions. Accurate prediction of k values from the excess chemical potential of anions in water suggests that anion-solvent interactions dominate the retention of amines in RPLC. Thus, controlling amine retention depends critically on judicious selection of mobile-phase anion (in addition to the usual experimental parameters such as organic modifier, temperature, pH, and stationary phase). Second, more lipophilic molecular anions can provide retention and tailing properties comparable to those obtained from traditional amphiphilic ion-pairing reagents such as octanesulfonate, but with the benefit of a superior gradient background and solubility at high concentrations of organic modifier.

Nicotine addiction has been identified as the primary contributor to continued widespread tobacco use worldwide. Although the health benefits of smoking cessation are well publicized, few smokers successfully quit on a long-term basis. A number of pharmacological agents have been shown to approximately double long-term smoking cessation rates and have, therefore, been recommended as first-line therapy for the treatment of nicotine dependence in the clinical practice guidelines recently released by the Agency for Healthcare Research and Quality (AHRQ). These include the currently available dosage forms of nicotine replacement therapy (gum, patch, nasal spray, and inhaler) and bupropion. Other agents that have exhibited some efficacy in increasing smoking cessation rates are nortriptyline and clonidine. All pharmacological treatments are most effective in conjunction with behavioral therapy. Other approaches to treating tobacco use disorder now being investigated include additional ways to administer nicotine, a vaccine to prevent nicotine from crossing the blood-brain barrier, and agents that alter the metabolism of nicotine. This review summarizes the characteristics of nicotine addiction, reviews the pharmacological agents currently used to treat tobacco use disorder, and describes possible approaches to treat nicotine dependence in the future.

Specific examples were extracted for presentation where data on drug use in the elderly corresponded with pharmacogenetic information. Specific examples were selected to illustrate pharmacogenetic influences on medications of clinical significance in the elderly population including meperidine, tramadol, amitriptyline, nortriptyline, flecainide, and propafenone. These medications were identified as intersecting points in the Beers criteria and pharmacogenetic guidelines provided by the Clinical Pharmacogenetics Implementation Consortium and the Dutch Pharmacogenetics Working Group, or where mechanisms of pharmacogenetic influences were applicable.

Insufficient data on the effectiveness and safety of any antidepressants therapies in Parkinson's disease are available on which to make recommendations for their use. Further large scale randomised controlled trials are urgently required in this area.
The performance of an enzyme immunoassay kit (EMIT) to diagnose intoxications with tricyclic antidepressants was compared with a high performance liquid chromatography (HPLC) technique in vitro and in vivo. The cut-off reference solution contained in the kit of nominally 1,140 nM nortriptyline varied from 1,250 to 1,600 nM. In vitro addition of antidepressants gave positive results (change in absorbance above the cut-off value) of approximately 1,100 nM for amitriptyline, imipramine, and desmethylimipramine and approximately 1,600 nM for clomipramine and desmethylclomipramine. In contrast, high concentrations of the tetracyclic antidepressant maprotiline (7,000 nM) and the bicyclic zimeldine (2,000 nM) gave negative results. False positive results were obtained with high concentrations of thioridazine (4,000 nM), chlorpromazine (300 nM), and alimemazine (trimeprazine) (5,000 nM). Of 51 patient samples, five gave readings above the cut-off value, consistent with a tricyclic antidepressant intoxication, but two of these were false positives as compared with the specific HPLC analysis. However, no false negative results were obtained with the EMIT. In conclusion, the EMIT kit is likely to detect intoxications with tricyclic antidepressants but miss intoxications with nontricyclic antidepressants. For a screening method, this is a serious drawback, since maprotiline and zimeldine together make up approximately 25% of the total of antidepressants used in Sweden. Users of the kit must also be aware that certain phenothiazines in high therapeutic doses or in intoxication cases could interfere with this test and might lead to the false diagnosis of intoxication with tricyclic antidepressants.
We identified cutoff values for the absolute mRNA measures that accurately predicted response probability on an individual basis, with positive predictive values and specificity for nonresponders of 100% in both samples (negative predictive value=82% to 85%, sensitivity=52% to 61%). Using network analysis, we identified different clusters of targets for these 2 cytokines, with Macrophage Migration Inhibitory Factor interacting predominantly with pathways involved in neurogenesis, neuroplasticity, and cell proliferation, and interleukin-1β interacting predominantly with pathways involved in the inflammasome complex, oxidative stress, and neurodegeneration.
Minimal brain dysfunction is a neurodevelopmental disorder which can be found in nearly 20% of school children. It is characterized by evidences of immaturity involving control of activity, emotions, and behavior, and by specific learning disabilities involving the communicating skills needed in reading, writing, and mathematics. The prime deficits in the classroom are an inability to maintain attention and concentration and an inability to skillfully blend the auditory and visual functions essential in language performance. Medical evaluation will reveal many of the "soft signs" of neurologic involvement, and educational appraisal will indicate a wide scatter in testing scores with a marked discrepancy between evaluated potential and actual classroom achievement. Remedial efforts directed at early detection, relief from pressure and unjust punishment or ridicule from parents and teachers, and adjustment of the educational environment with consideration of the child's individual talents, combined with the judicious use of medications to prolong attention span and improve neurodevelopmental maturity, hold promise of improving the lot of most involved children. There are valid indications that expansion of such programs can do much to prevent these youngsters from developing severe personality maladjustment and delinquent behavior, as well as emotional illness in later life.

Longitudinal latent class analysis was applied in a secondary analysis of data obtained from the Genome-Based Therapeutic Drugs for Depression (GENDEP) study. In the GENDEP trial, conducted in 9 European academic psychiatry centers from July 2004 to June 2008, 811 treatment-seeking adult subjects with DSM-IV major depression received escitalopram or nortriptyline for 12 weeks. Montgomery-Asberg Depression Rating Scale measurements were taken weekly. The secondary analysis reported in this article was conducted in 2010.
Standardized psychotherapy and pharmacotherapy are effective for patients with major depression with and without a generalized anxiety disorder. However, the longer time to recovery for the former group and lack of response to these treatments by patients with lifetime panic disorder suggest that primary care physicians should carefully assess history of anxiety disorder among depressed patients so as to select a proper intervention.
Antidepressants, especially tricyclic agents (TCAs), are increasingly used in geriatric patients since depression is a common mood disorder in the elderly and the size of elderly population is increasing. Notwithstanding the importance of kinetics to better use of drugs, its study in the elderly (regarding TCAs) is not sufficiently developed. The present paper briefly reviews the available data on amitriptyline, nortriptyline, protriptyline, imipramine, desipramine and clomipramine kinetics in the elderly.

The melanin-concentrating hormone (MCH) is a peptidergic neuromodulator synthesized by neurons of the lateral sector of the posterior hypothalamus and zona incerta. MCHergic neurons project throughout the central nervous system, including areas such as the dorsal (DR) and median (MR) raphe nuclei, which are involved in the control of sleep and mood. Major Depression (MD) is a prevalent psychiatric disease diagnosed on the basis of symptomatic criteria such as sadness or melancholia, guilt, irritability, and anhedonia. A short REM sleep latency (i.e., the interval between sleep onset and the first REM sleep period), as well as an increase in the duration of REM sleep and the density of rapid-eye movements during this state, are considered important biological markers of depression. The fact that the greatest firing rate of MCHergic neurons occurs during REM sleep and that optogenetic stimulation of these neurons induces sleep, tends to indicate that MCH plays a critical role in the generation and maintenance of sleep, especially REM sleep. In addition, the acute microinjection of MCH into the DR promotes REM sleep, while immunoneutralization of this peptide within the DR decreases the time spent in this state. Moreover, microinjections of MCH into either the DR or MR promote a depressive-like behavior. In the DR, this effect is prevented by the systemic administration of antidepressant drugs (either fluoxetine or nortriptyline) and blocked by the intra-DR microinjection of a specific MCH receptor antagonist. Using electrophysiological and microdialysis techniques we demonstrated also that MCH decreases the activity of serotonergic DR neurons. Therefore, there are substantive experimental data suggesting that the MCHergic system plays a role in the control of REM sleep and, in addition, in the pathophysiology of depression. Consequently, in the present report, we summarize and evaluate the current data and hypotheses related to the role of MCH in REM sleep and MD.
It is not possible to draw any clear conclusions about the effectiveness of antidepressants given immediately postpartum in preventing postnatal depression and, therefore, cannot be recommended for prophylaxis of postnatal depression, due to the lack of clear evidence. Larger trials are needed which also include comparisons of antidepressant drugs with other prophylactic treatments to reflect clinical practice, and examine adverse effects for the foetus and infant, as well as assess womens' attitudes to the use of antidepressants at this time.

The neuropsychiatry of Parkinson's disease (PD) and its correlates are reviewed. Dementia occurs in up to 30% and can be treated with cholinesterase inhibitors. Cognitive impairments involve executive, visuospatial, attentional, and memory dysfunctions. Apathy may respond to dopamine agonists or cholines-terase inhibitors. Cognitive impairment, psychosis, and depression predict quality of life. Visual hallucinations and paranoia are common, and respond to low dose clozapine. Depression is common and predicts caregiver burden and depression. The best data suggest the efficacy of nortriptyline and the safety of SSRIs. Anxiety disorders occur in 40% of patients, especially off-period panic attacks and specific phobias. Bromazepam has proven useful for anxiety in PD, but buspirone has only diminished drug-induced dyskinesias to date. Sleep disorders occur in up to 94% of patients. Insomnia is common and is treated by dopaminergic agent dose reduction, nocturnal dosing, treatment of depression, or use of short half-lived hypnotics, depending on etiology. Parasomnias include REM behavior disorder and vivid dreams and nightmares. Excessive daytime somnolence occurs in at least 15% of patients. Sleep attacks are common and patients should be warned about driving when taking dopamine agonists. Sexual disorders occur in most patients. Paraphilias are associated with dopamine agonists, and clozapine may be useful in their treatment. Surgical therapies are associated with a wide variety of neuropsychiatric features, and vigilance for suicide attempts with subthalamic nucleus stimulation seems warranted. Neuropsychiatric disorders are important determinants of quality of life and caregiver burden in PD. More clinical research is needed to establish effective treatments.

Increases in suicidal ideation were associated with depression severity and decreased during antidepressant treatment. In men, treatment with escitalopram is associated with lower risk of suicidal ideation compared to nortriptyline. Clinicians should remain alert to suicidal ideation beyond the initial weeks of antidepressant treatment.

In geriatric patients with recurrent major depression, maintenance treatment with nortriptyline or IPT is superior to placebo in preventing or delaying recurrence. Combined treatment using both appears to be the optimal clinical strategy in preserving recovery.
This study was designed to evaluate the comparative efficacy and safety of sertraline and nortriptyline for the treatment of major depressive disorder in older adults.
