Asthma is an inflammatory disease characterized by airway hyperresponsiveness, airway remodeling, and airway inflammation. In recent years, the prevalence of asthma has been increasing steadily and the pathogenesis of asthma varies from person to person. Due to poor compliance or resistance, existing drugs cannot achieve the desired therapeutic effect. Therefore, developing or screening asthma therapeutic drugs with high curative effects, low toxicity, and strong specificity is very urgent. Duloxetine HCl (DUX) is a selective serotonin and norepinephrine reuptake inhibitor, and it was mainly used to treat depression, osteoarthritis, and neuropathic pain. It was also reported that DUX has potential anti-infection, anti-inflammation, analgesic, antioxidative, and other pharmacological effects. However, whether DUX has some effects on asthma remains unknown. In order to investigate it, a series of ex vivo and in vivo experiments, including biological tension tests, patch clamp, histopathological analysis, lung function detection, oxidative stress enzyme activity detection, and molecular biology experiments, were designed in this study. We found that DUX can not only relax high potassium or ACh precontracted tracheal smooth muscle by regulating L-type voltage-dependent Ca channel (L-VDCC) and nonselective cation channel (NSCC) ion channels but also alleviate asthma symptoms through anti-inflammatory and antioxidative response regulated by PI3K/AKT/mTOR and Nrf2/HO-1 signaling pathways. Our data suggests that DUX is expected to become a potential new drug for relieving or treating asthma.

Review
BACKGROUND
Although a large variety of antidepressants agents (AD) with different mechanisms of action are available, no significant differences in efficacy and safety have been shown. However, there have been few attempts to incorporate data on subjective experiences under different AD.
METHOD
We conducted a qualitative and quantitative analysis of the posts from the website www.askapatient.com from different AD. We reviewed a random sample of 1000 posts.
RESULT
After applying the inclusion and exclusion criteria, we included a final sample of 450 posts, 50 on each of the most used AD: sertraline, citalopram, paroxetine, escitalopram, fluoxetine, venlafaxine, duloxetine, mirtazapine, and bupropion. Bupropion, citalopram, and venlafaxine had the higher overall satisfaction ratings. Sertraline, paroxetine, and fluoxetine had high reports of emotional blunting, while bupropion very few. Overall satisfaction with AD treatment was inversely associated with the presence of the following side-effects: suicidality, irritability, emotional blunting, cognitive disturbances, and withdrawal symptoms. After adjusting for confounders, only emotional blunting was shown to be more frequently reported by users of serotonergic agents, as compared to non-serotoninergic agents.
CONCLUSION
This research points out that the subjective experience of patients under treatment should be taken into consideration when selecting an AD as differences between agents were evident. In contrast to the more frequent treatment decisions, users might prefer receiving a non-serotoninergic agent over a serotonergic one due to their lower propensity to produce emotional blunting.

Meta-Analysis
OBJECTIVE
The aim was to evaluate the efficacy and safety of duloxetine for postoperative recovery after total knee arthroplasty.
METHODS
The following electronic databases were searched for eligible trials: PubMed, EMBASE, Web of Science, Cochrane Library, VIP, Wanfang Data, and China National Knowledge Infrastructure (CNKI). The search was performed from the inception dates to 10 August 2022. Data extraction and quality assessment were performed by two independent reviewers. Standard mean differences or mean differences with 95% CIs for pooled data were calculated. The primary outcomes were pain, physical function, and analgesic consumption. Secondary outcomes included range of motion (ROM) of the knee, depression, and mental health.
RESULTS
This meta-analysis included 11 studies, reporting on a total of 1019 patients. Results of analyses indicated that duloxetine showed a statistically significant reduction in pain at rest at 3 days, 1 week, 2, and 6 weeks and pain on movement at 5 days, 1 week, 2, 4, 6, and 8 weeks. However, there was no statistical significance in pain at rest and on movement at 24 h, 12 weeks, 6 months, and 12 months. Additionally, duloxetine had a significant improvement in physical function, ROM of the knee at 6 weeks, and emotional function (depression and mental health). Moreover, the cumulative opioid consumption at 24 h in the duloxetine groups was lower than in the control groups. But there was no statistical significance for the cumulative opioid consumption over 7 days between the duloxetine groups and controls.
CONCLUSIONS
In conclusion, duloxetine might reduce pain mainly over a time span of 3 days-8 weeks and lower cumulative opioid consumption within 24 h. In addition, it improved physical function, ROM of the knee with a time span of 1-6 weeks and emotional function (depression and mental health).

Review
BACKGROUND
Duloxetine and amitriptyline are antidepressants used in the treatment of fibromyalgia. In published systematic reviews, there is no agreement about which drug is more effective and safer. This study aimed to compare evidence of the efficacy and safety of duloxetine compared with amitriptyline in the treatment of adult patients with fibromyalgia. This work contributes to guiding clinicians on the use of duloxetine or amitriptyline for the treatment of fibromyalgia and provides information for public health decision-makers.
METHODS
Overview of systematic reviews of clinical trials comparing duloxetine and amitriptyline in the treatment of fibromyalgia. The reviews were screened in Cochrane, PubMed, EMBASE, and SRDR with no restrictions on language and year of publication, considering that the research was conducted in July 2018 and updated until May 2020. The selection was based on the following criteria: adult patients with a diagnosis of fibromyalgia treated with duloxetine or amitriptyline, comparing the efficacy and safety in pain, fatigue, sleep, and mood disorder symptoms and quality of life, in addition to the acceptability of these antidepressants. The methodological quality and strength of evidence were assessed using the AMSTAR and GRADE instruments.
RESULTS
Eight systematic reviews were selected. Amitriptyline had low evidence for pain, moderate evidence for sleep and fatigue, and high evidence for quality of life. Duloxetine had high quality of evidence in patients with mood disorders. With low evidence, duloxetine has higher acceptability, but is safer in older patients, while amitriptyline is safer for non-elderly individuals.
CONCLUSION
Both antidepressants are effective in the treatment of fibromyalgia, differing according to the patient's symptoms and profile.

Journal of the American Veterinary... Nov 2019To describe abnormal clinical signs following duloxetine ingestion in dogs.
OBJECTIVE
To describe abnormal clinical signs following duloxetine ingestion in dogs.
ANIMALS
364 client-owned dogs that ingested duloxetine.
PROCEDURES
The American Society for the Prevention of Cruelty to Animals, Animal Poison Control Center electronic database was searched for records of dogs with duloxetine ingestion between January 2012 and December 2016. Data collected included age, body weight, breed, duloxetine exposure and dose, clinical signs, and overall outcome. Clinical signs were categorized as either neurologic, digestive, cardiovascular, respiratory, or metabolic and endocrine. Outcomes were categorized as no clinical signs, fully recovered, died, or unknown.
RESULTS
Clinical signs developed in 55 of the 364 (15.1%) dogs with known ingestion of duloxetine. The most common clinical signs were lethargy (22/55 [40%]), mydriasis (18/55 [33%]), vomiting (11/55 [20%]), and trembling (6/55 [11%]). Dogs that ingested an estimated dose of duloxetine ≥ 20 mg/kg (9.1 mg/lb) were more likely to have had abnormal clinical signs than were dogs that ingested < 20 mg/kg.
CONCLUSIONS AND CLINICAL RELEVANCE
Findings indicated that most dogs in the present study did not have clinical signs associated with ingestion of duloxetine and that development of clinical signs varied by individual dog. Further information is needed to determine toxic dose ranges for duloxetine ingestion in dogs. ( 2019;255:1161-1166).

Randomized Controlled Trial
OBJECTIVES
Fibromyalgia (FM) is characterised by a form of debilitating pain that is unresponsive to standard analgesics. The aim of this study was to evaluate the efficacy of supplementing ongoing pregabalin (PGB) and duloxetine (DLX) treatment with palmitoylethanolamide (PEA) and acetyl-L-carnitine (ALC) for 24 weeks in FM patients.
METHODS
After undergoing three months of stable treatment with DLX+PGB, FM patients were randomised to continue the same treatment (Group 1) or to add PEA 600 mg b.i.d + ALC 500 mg b.i.d. (Group 2) for a further 12 weeks. Every two weeks throughout the study, cumulative disease severity was estimated using the Widespread Pain Index (WPI) as the primary outcome measure; the secondary outcomes were the fortnightly scores of the patient-completed revised Fibromyalgia Impact Questionnaire (FIQR) and the modified Fibromyalgia Assessment Status (FASmod) questionnaire. All three measures were expressed as time-integrated area under the curve (AUC) values.
RESULTS
One hundred and thirty (91.5%) of the initial 142 FM patients completed the study: 68 patients in Group 1 and 62 in Group 2. Twenty-four weeks after randomisation, the Group 2 patients showed additional significant improvements in all three outcome measures. Although there was some fluctuation in both groups during the study period, the AUC values of the WPI scores steadily decreased in Group 2 (p=0.048), which also showed better outcomes in terms of the AUC values of the FIQR (p=0.033) and FASmod scores (p=0.017).
CONCLUSIONS
This is the first randomised controlled study demonstrating the effectiveness of the adding on therapy of PEA+ALC to DLX+PGB in FM patients.

AIM
As few randomized clinical trials have verified the efficacy of selective and norepinephrine reuptake inhibitors in IBS, the current study made an inclusive comparison between them, and their effectiveness in IBS-C was proven.
BACKGROUND
Irritable bowel syndrome with constipation (IBS-C) is a functional bowel disorder characterized by changes in bowel movements and abdominal pain in the absence of identifiable structural abnormalities. Despite much progress in the treatment of other types of IBS, limited treatments are available for IBS-C.
METHODS
The study population comprised 182 IBS-C patients who were randomly divided into 3 groups according to treatment type. One group was given 20 mg of dicyclomine and fluoxetine, the second group received dicyclomine along with duloxetine hydrochloride, and the third group received dicyclomine only for two months. The severity of symptoms was recorded by questionnaire at the beginning and end of the treatment.
RESULTS
The average age and BMI of the patients were 28.5 ± 5.2 years and 25.2 ± 2.4 kg/m2, respectively. Duloxetine was more effective than fluoxetine in reducing flatulence (=0.043), abdominal pain intensity (≤0.046), and duration (≤0.003), in increasing the quality of life (≤0.046), and the frequency of fecal excretion in patients (≤0.004).
CONCLUSION
Based on the study findings, fluoxetine and duloxetine had greater therapeutic effects on all symptoms of IBD than dicyclomine, with duloxetine, specifically, being more effective than fluoxetine. Further studies on larger groups are suggested to determine the best dosage and identify any potential side effects of these drugs.

Meta-Analysis
BACKGROUND
Duloxetine, a serotonin-norepinephrine dual reuptake inhibitor, may improve analgesia after total joint arthroplasty (TJA). However, there is still no consensus on its effectiveness and safety. We conducted the meta-analysis to investigate the analgesic effect and safety of duloxetine for the treatment of patients received total knee or hip arthroplasty.
METHODS
Pubmed, Cochrane Central Registry for Clinical Trials, Embase, OVID, Web of Science, and Google Scholar were searched using a predetermined search strategy from inception to September 21, 2022. Only randomized controlled trials of duloxetine in treatment of patients after total knee or hip arthroplasty were included. Data collection and extraction, quality assessment, and data analyses were performed according to the Cochrane standards.
RESULTS
A total of 8 randomized controlled trials with 739 patients were included in the literature review of postoperative pain and adverse effects. The result of meta-analysis showed statistically significant lower opioid requirement with duloxetine (P < .05) for the different postoperative period. Duloxetine group had significant reductions in visual analog score for the 24-hour (walking: WMD = -0.98; 95% confidence interval [CI] = -1.69 to -0.26, P = .007; resting: WMD = -1.06; 95%CI = -1.85 to -0.27, P = .008) and 1-week (walking: WMD = -0.96; 95%CI = -1.42 to -0.50, P < .001; resting: WMD = -0.69; 95%CI = -1.22 to -0.16, P = .01); knee injury and osteoarthritis outcome score over 3-month (WMD = 2.94; 95%CI = -0.30 to 6.18, P = .008) and complication (odds ratio = 4.74; 95%CI = 0.23 to 96.56, P = .01) postoperative period compared with the control group. However, no difference on numeric rating scale (P > .05) for the different postoperative period; visual analog score (P > .05) for the 6-week or 3-month and knee injury and osteoarthritis outcome score (P > .05) for the 6-week postoperative period. Furthermore, it did not increase the incidence of adverse effects (odds ratio = 0.87; 95%CI = 0.72 to 1.05, P = .15).
CONCLUSION
Duloxetine could decrease the opioids consumption and relieve early postoperative pain without increasing the risk of adverse medication effects in patients undergoing total knee or hip arthroplasty. Considering the ongoing opioid epidemic, duloxetine could act as a good supplement in multimodal pain management protocol for patients undergoing total joint arthroplasty.
