PURPOSE
Neuropathic corneal pain (NCP) is a recently acknowledged disease entity. However, there is no consensus in potential treatment strategies, particularly in patients with a centralized component of pain. This study aims to assess the efficacy and tolerability of the tricyclic antidepressant, nortriptyline, among NCP patients.
METHODS
Patients with clinically diagnosed NCP and a centralized component of pain, treated with oral nortriptyline, who had recorded pain scores as assessed by the ocular pain assessment survey at the first and last visit were included. Patients were excluded if they had any other ocular pathology that might result in pain or had less than 4 weeks of nortriptyline use. Demographics, time between visits, concomitant medications, systemic and ocular co-morbidities, duration of NCP, side effects, ocular pain scores, and quality of life (QoL) assessment were recorded.
RESULTS
Thirty patients with a mean age of 53.1 ± 18.5 were included. Male to female ratio was 8:22. Mean ocular pain in the past 24 h improved from 5.7 ± 2.1 to 3.6 ± 2.1 after 10.5 ± 9.1 months (p < 0.0001). Twelve patients (40.0%) had equal to or more than 50% improvement, 6 patients (20.0%) had 30-49% improvement, 6 patients (20.0%) had 1-29% improvement, 4 patients (13.3%) did not improve, while 2 patients (6.7%) reported increase in pain levels. Mean QoL improved from 6.0 ± 2.5 to 4.3 ± 2.4 (p = 0.019). Eight patients (26.6%) discontinued treatment due to persistent side effects, despite improvement by 22.4%.
CONCLUSION
Nortriptyline was effective in relieving NCP symptoms in patients with centralized component and insufficient response to other systemic and topical therapies who tolerated the drug for at least 4 weeks. Nortriptyline may be used in the management of patients with NCP.

Room tilt illusion (RTI) is a rare and transient perceptual disturbance in which an individual perceives their surroundings as having been rotated or tilted, usually at 90 or 180 degrees. Primarily linked with vestibular disorders and neurological lesions, this report details the only reported occurrence of the RTI phenomena in nortriptyline use for treatment-refractory depression. The patient developed RTI six days after starting the medication and the disturbance resolved after medication cessation. Although the mechanism behind such a phenomenon with medication use has not been elucidated, its etiology may rest on the effect of tricyclic antidepressants on the vestibulo-thalamo-cortical system and visual-vestibular integration. Clinicians should be aware of the potential for such a medication-induced perceptual disturbance, especially in the workup for more serious etiologies in elderly patients with co-morbidities.

Review
The prevalence of non-motor symptoms in Parkinson's disease (PD) is high. Depression varies from 20 to 50% of the PD patients, and is associated with increasing disability. The key characteristics of depression are anhedonia and low mood. The recommended scales for screening purposes are: HAM-D, BDI, HADS, MADRS and GDS. As for measurement of severity: HAM-D, MADRS, BDI and SDS. In cases with mild depression, non-pharmacological intervention is the treatment of choice. In moderate depression, antidepressants are required. The choice of an antidepressant should be based mainly on the comorbidities and unique features of the patient. Evidence for antidepressant effectiveness is seen mostly with amitriptyline and nortriptyline, but one should be cautious in elderly patients. Other antidepressants that can be prescribed are: citalopram, escitalopram, sertraline, bupropion, trazodone, venlafaxine, mirtazapine and duloxetin. The dopaminergic agonist pramipexole is a treatment option.

BACKGROUND
Although tinnitus has a prevalence between 20 and 42.8%, the currently recommended management for tinnitus, such as tinnitus support and psychologic therapies, are relatively time-consuming and expensive. Several new pharmacologic treatments designed for tinnitus patients without specific origin had been developed but their efficacy remains unclear.
METHODS
The current Network Meta-Analysis (NMA) of randomised controlled trials (RCTs) was conducted to evaluate the efficacy of different pharmacologic treatments for tinnitus management in tinnitus patients without specific or treatable origin (i.e. primary tinnitus). Databases were searched from inception to April 5, 2021. All network meta-analytic procedures were conducted under the frequentist model. We calculated the effect size of outcomes with different rating scales with standardized mean difference. PROSPERO registration: CRD42020177742.
FINDINGS
Overall, 36 RCTs were included with 2,761 participants. The main results revealed that pharmacologic interventions with brain-acting effect (for example, amitriptyline, acamprosate, and gabapentin) and those with anti-inflammation/anti-oxidant effect (for example, intra-tympanic dexamethasone injection plus oral melatonin) were associated with superior improvement in tinnitus severity and response rate compared to placebo/control. Oral amitriptyline were associated with the highest improvement in tinnitus severity and the fourth highest response rate. None of the investigated interventions was associated with different changes in quality of life compared to placebo/control. All the investigated treatments were associated with similar drop-out rate to placebo/control.
INTERPRETATION
The current NMA suggests a potential role for treatments with brain-acting effect (for example, amitriptyline, acamprosate, and gabapentin) or anti-inflammation/anti-oxidant effect (for example, intra-tympanic dexamethasone injection plus oral melatonin) as the preferable effective treatments for tinnitus without specific or treatable origin.

Review
The aim of this study was to discuss the therapeutic substances used to treat nicotine addiction, not registered in Poland. This paper presents the results of the latest clinical trials and the possibility of their use in the treatment of nicotine addiction. The first two discussed drugs clonidine and nortriptyline are recommended by clinical practice guidelines AHRQ (Agency for Healthcare Research and Quality) as the substance of the second line in the fight against addiction. Nortriptyline belongs to tricyclic antidepressants. Its mechanism of action is the inhibition of the reuptake of norepinephrine. It is suggested as the antagonist of activity of nicotinic receptors. The results confirm its efficacy in the treatment of nicotine addiction, but many side effects limit its use. Clonidine acts presumably by inhibition of sympathetic hyperactivity characteristic of symptoms associated with nicotine rehab. The remaining compounds under discussion, such as: venlafaxine, fluoxetine, moclobemide and rimonabant, are not registered in any country with an indication to use in the treatment of nicotine addiction, however, due to the mechanism in which they act, the possibility of their use in the treatment of this disease is considered. The possibility of using anxiolytics such as: buspirone, diazepam, meprobamate and beta-blockers: metoprolol and oxprenolol is also considered in order to treat the anxiety appearing as one of the symptoms of abstinence. An interesting proposal to combat nicotine addiction are vaccines--NicVAX, CYT002-NicQb and TA-NIC. Currently, they are in clinical phase I and II of their development. Their operation would be based on the induction of specific antibodies that bind nicotine in the plasma, thus prevent it reaching the nicotinic receptors. Preliminary results confirm the possible positive effects in the prevention and treatment of nicotine addiction.

Randomized Controlled Trial
OBJECTIVE
There is limited evidence that adding an antidepressant to electroconvulsive therapy (ECT), compared with ECT monotherapy, improves outcomes. We aimed to determine whether the addition of nortriptyline to ECT enhances its efficacy and prevents post-ECT relapse.
METHODS
We conducted a randomized, double-blind, placebo-controlled trial (RCT). Patients with major depressive disorder and an indication for ECT received either nortriptyline or placebo during a bilateral ECT course. Outcome measures were mean decrease in Hamilton Rating Scale for Depression (HRSD) score, response, remission, and time to response and remission. Patients who attained remission participated in a 1-year follow-up study with open-label nortriptyline. Outcome measures were relapse and time to relapse.
RESULTS
We included 47 patients in the RCT. In the nortriptyline group, 83% showed response, 74% attained remission, and the mean decrease in HRSD score was 21.6 points. In the placebo group these figures were, respectively, 81% (p = 0.945), 73% (p = 0.928) and 20.7 points (p = 0.748). Thirty-one patients participated in the follow-up study. In patients who had received nortriptyline during the RCT, 47% relapsed at a mean of 34.2 weeks. Patients who had received placebo showed similar treatment results. In both study phases, no statistically significant differences between the nortriptyline and the placebo group were found.
CONCLUSION
In our sample of severely depressed patients who were often medication resistant and suffering from psychotic depression, the addition of nortriptyline to ECT did not enhance its efficacy or prevent post-ECT relapse. Encouragingly, even in these patients ECT was highly effective and relapse rates were relatively low.

Review
Depression in Parkinson's disease (PD) is common, and it appears to worsen the motor and cognitive progression of the disease, and limits the patient's quality of life. In this paper, we review the pharmacotherapy of depression in people with PD. We find that evidence is sparse when it comes to this patient population. There is some evidence that older tricyclic antidepressants (nortriptyline and desipramine) may be effective in this population. There is also growing evidence that newer antidepressants like paroxetine and venlafaxine may be effective. We will also review a number of other promising medication treatments. What is apparent is the need for more research identifying the most effective medications for treating depression in this population. We provide recommendations that fall in line with current evidence-based practice for managing depression in the general population. Also, we suggest that collaborative models of depression care may be a promising approach to support the identification and effective treatment of those with PD also suffering from depressive disorders.

Review
BACKGROUND
Antidepressants are widely used to treat chronic neuropathic pain (pain due to nerve damage), usually in doses below those at which they exert antidepressant effects. An earlier review that included all antidepressants for neuropathic pain is being replaced by new reviews of individual drugs examining individual neuropathic pain conditions.Nortriptyline is a tricyclic antidepressant that is occasionally used for treating neuropathic pain, and is recommended in European, UK, and USA guidelines.
OBJECTIVES
To assess the analgesic efficacy and associated adverse events of nortriptyline for chronic neuropathic pain in adults.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and EMBASE from inception to 7 January 2015, and the reference lists of retrieved papers and other reviews. We also searched two clinical trials databases for ongoing or unpublished studies.
SELECTION CRITERIA
We included randomised, double-blind studies of at least two weeks' duration comparing nortriptyline with placebo or another active treatment in chronic neuropathic pain. Participants were adults aged 18 years and over. We included only full journal publication articles and clinical trial summaries.
DATA COLLECTION AND ANALYSIS
Two review authors independently extracted efficacy and adverse event data, and examined issues of study quality. We considered the evidence using three tiers. First tier evidence derived from data meeting current best standards and subject to minimal risk of bias (outcome equivalent to substantial pain intensity reduction, intention-to-treat analysis without imputation for dropouts; at least 200 participants in the comparison, 8 to 12 weeks' duration, parallel design); second tier evidence from data that failed to meet one or more of these criteria and were considered at some risk of bias but with adequate numbers in the comparison; and third tier evidence from data involving small numbers of participants that was considered very likely to be biased or used outcomes of limited clinical utility, or both.We planned to calculate risk ratio (RR) and numbers needed to treat for an additional beneficial outcome (NNT) and harmful outcome (NNH) using standard methods expected by The Cochrane Collaboration.
MAIN RESULTS
We included six studies treating 310 participants (mean or median age 49 to 64 years) with various neuropathic pain conditions. Five studies used a cross-over design, and one used a parallel-group design; 272 participants were randomised to treatment with nortriptyline, 145 to placebo, 94 to gabapentin, 56 to gabapentin plus nortriptyline, 55 to morphine, 55 to morphine plus nortriptyline, 39 to chlorimipramine, and 33 to amitriptyline. Treatment periods lasted from three to eight weeks. All studies had one or more sources of potential major bias.No study provided first or second tier evidence for any outcome. Only one study reported our primary outcome of people with at least 50% reduction in pain. There was no indication that either nortriptyline or gabapentin was more effective in postherpetic neuralgia (very low quality evidence). Two studies reported the number of people with at least moderate pain relief, and one reported the number who were satisfied with their pain relief and had tolerable adverse effects. We considered these outcomes to be equivalent to our other primary outcome of Patient Global Impression of Change (PGIC) much or very much improved.We could not pool data, but third tier evidence in individual studies indicated similar efficacy to other active interventions (gabapentin, morphine, chlorimipramine, and amitriptyline), and to placebo in the conditions studied (very low quality evidence). Adverse event reporting was inconsistent and fragmented. More participants reported adverse events with nortriptyline than with placebo, similar numbers with nortriptyline and other antidepressants (amitriptyline and chlorimipramine) and gabapentin, and slightly more with morphine (very low quality evidence). No study reported any serious adverse events or deaths.
AUTHORS' CONCLUSIONS
We found little evidence to support the use of nortriptyline to treat the neuropathic pain conditions included in this review. There were no studies in the treatment of trigeminal neuralgia. The studies were methodologically flawed, largely due to small size, and potentially subject to major bias. The results of this review do not support the use of nortriptyline as a first line treatment. Effective medicines with much greater supportive evidence are available, such as duloxetine and pregabalin.

Gastroenterology and Hepatology From... 2023In the current clinical trial study, the potency of mirtazapine and nortriptyline was compared in patients with Functional Dyspepsia (FD) who had anxiety or depression.
AIM
In the current clinical trial study, the potency of mirtazapine and nortriptyline was compared in patients with Functional Dyspepsia (FD) who had anxiety or depression.
BACKGROUND
FD usually accompanies other psychosocial disorders. According to previous studies, among these disorders, anxiety and depression have the most correlation.
METHODS
This randomized clinical trial was organized in Taleghani hospital (Tehran, Iran). In two parallel groups, 42 patients were treated for 12 weeks, with 22 patients receiving 7.5 mg of mirtazapine and 20 patients receiving 25 mg of nortriptyline per day. To gain robust results, the patients with a positive history of antidepressant therapy, organic diseases, alcohol abuse, pregnancy, and major psychiatric disorders were excluded from the study. The subjects were examined by three questionnaires, including Nepean and Hamilton questionnaires. The patients were asked to answer the questions three times during the study: once before the onset of the treatment, second during the treatment, and third at the end of the treatment.
RESULTS
Based on Gastrointestinal (GI) manifestations, mirtazapine, in comparison to nortriptyline could significantly suppress the signs and symptoms of FD, including epigastric pains (P=0.02), belching (P=0.004), and bloating (P=0.01). Although the results from the use of mirtazapine compared to the use of nortriptyline (P=0.002) showed a lower mean depression score on the Hamilton questionnaire, no significant differences were found between the effects of these drugs on the anxiety scale of patients (P=0.091).
CONCLUSION
Mirtazapine is more effective for GI symptoms related to gastric emptying. Considering the level of anxiety, mirtazapine, compared to nortriptyline, revealed better outcomes in FD patients suffering from depression.
