Development and Challenges of Diclofenac-Based Novel Therapeutics: Targeting Cancer and Complex Diseases. Cancers (Basel) 2022; 14:cancers14184385. [PMID: 36139546 PMCID: PMC9496891 DOI: 10.3390/cancers14184385] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2022] [Revised: 09/05/2022] [Accepted: 09/06/2022] [Indexed: 11/17/2022] Open
Abstract
Simple Summary Diclofenac is a widely used drug for its anti-inflammatory and pain alleviating properties. This review summarizes the current understanding about the drug diclofenac. The potential applications of diclofenac beyond its well-known anti-inflammatory properties for other diseases such as cancer are discussed, along with existing limitations. Abstract Diclofenac is a highly prescribed non-steroidal anti-inflammatory drug (NSAID) that relieves inflammation, pain, fever, and aches, used at different doses depending on clinical conditions. This drug inhibits cyclooxygenase-1 and cyclooxygenase-2 enzymes, which are responsible for the generation of prostaglandin synthesis. To improve current diclofenac-based therapies, we require new molecular systematic therapeutic approaches to reduce complex multifactorial effects. However, the critical challenge that appears with diclofenac and other drugs of the same class is their side effects, such as signs of stomach injuries, kidney problems, cardiovascular issues, hepatic issues, and diarrhea. In this article, we discuss why defining diclofenac-based mechanisms, pharmacological features, and its medicinal properties are needed to direct future drug development against neurodegeneration and imperfect ageing and to improve cancer therapy. In addition, we describe various advance molecular mechanisms and fundamental aspects linked with diclofenac which can strengthen and enable the better designing of new derivatives of diclofenac to overcome critical challenges and improve their applications.

Abstract
Given the current demographic changes there are an increasing number of elderly and very elderly patients in outpatient and inpatient care. Elderly and very elderly patients often suffer from pain and musculoskeletal conditions are a common cause of pain in the elderly. An effective pain management should not be withheld from elderly patients with rheumatic diseases. Untreated pain in elderly patients leads to functional impairment and immobility. In addition, the quality of life of patients is negatively affected and can lead to a loss of autonomy and/or social withdrawal. The treatment of elderly and very elderly patients is particularly challenging. There are special features that need to be considered in the choice of treatment. Altered pain presentation, comorbidities, nonadherence, polypharmacy and side effects of pain medications require a critical risk-benefit assessment and ongoing treatment monitoring of this special group of patients.

Abstract
OBJECTIVE To observe the efficacy and safety of oral sanhuangwuji powder, anti-rheumatic drugs (ARDs), and ginger-partitioned acupoint stimulation at zusanli (ST 36) on the treatment of rheumatoid arthritis (RA) complicated by peptic ulcer. METHODS This prospective randomized controlled study included 180 eligible inpatients and outpatients randomly assigned to an ARD treatment (n.= 60), ginger-partitioned stimulation (n = 60), or combination treatment (n = 60). Patients assigned to the ARD group were given oral celecoxib, methotrexate, and esomeprazole. Patients assigned to the ginger-partitioned stimulation group were given ginger-partitioned acupoint stimulation at zusanli (ST 36) in addition to the ARDs. Patients in the combination treatment group were given oral sanhuangwuji powder, ginger-partitioned acupoint stimulation at susanli (ST 36), and ARDs. All patients were followed up for 2 months to evaluate clinical effects and safety. The study was registered in the World Health Organization database at the General Hospital of Chengdu Military Area Command Chinese People's Liberation Army (ChiCTR-TCC12002824). RESULTS The combination treatment group had significantly greater improvements in RA symptoms, laboratory outcomes, and gastrointestinal symptom scores, compared with the other groups (P < 0.05). The peptic ulcer healing rate in the combination treatment group was significantly greater than that in the ARD treatment group (χ2= 16.875, P < 0.05) and the ginger-partitioned stimulation group (χ2= 6.171, P < 0.05). CONCLUSION Combination treatment with ginger-partitioned acupoint stimulation at zusanli (ST 36), oral sanhuangwuji powder, and ARDs had a better clinical effect for RA with complicated peptic ulcer, compared with ARD treatmentalone or in combination with ginger-partitioned acupoint stimulation.

World J Gastroenterol 2014; 20:10504-10511. [PMID: 25132768 PMCID: PMC4130859 DOI: 10.3748/wjg.v20.i30.10504] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2014] [Revised: 02/28/2014] [Accepted: 04/23/2014] [Indexed: 02/06/2023] Open
Abstract
AIM: To calculate the proportion of potentially preventable hospitalizations due to peptic ulcer disease (PUD), erosive gastritis (EG) or duodenitis (ED).
METHODS: Retrospective cohort study using ICD-10 codes to identify all patients with upper gastrointestinal hemorrhage secondary to endoscopically proven PUD, EG or ED during the period from March 2007 to October 2010 in three major metropolitan hospitals in Melbourne, Australia. Patients were divided into “high risk” (those who would benefit from gastroprotection) and “not high risk” groups as defined by established guidelines. Mean Rockall score, transfusion requirement, length of stay, rebleeding rates, need for surgery and in-hospital mortality was compared between “high risk” and “not high risk” groups. Within the “high risk” group, those on gastroprotection and those with no gastroprotection were also compared.
RESULTS: Five hundred and seven patients were included for analysis of which 174 were classified as high risk. Median values of complete Rockall Score (5 vs 4, P = 0.002) and length of stay (5 d vs 4 d, P = 0.04) were higher in the high risk group but in-hospital mortality was lower (0.6% vs 3.9%, P = 0.03). 130 out of the 174 patients in the high risk group were not taking recommended gastroprotective therapy prior to hospitalization. Past history of PUD (OR = 3.7, P = 0.006) and clopidogrel use (OR = 3.2, P = 0.007) significantly predicted prescription of gastroprotective therapy. Using proton pump inhibitor protection rates of 50%-85% from published studies, an estimation of 13% to 22% of the total number of the hospitalizations due to PUD or EG/ED related bleeding may have been preventable.
CONCLUSION: Up to one fifth of all hospitalizations for bleeding secondary to PUD or EG/ED are potentially preventable.

Abstract
BACKGROUND & AIMS We established a working group to examine the burden of atherothrombotic and musculoskeletal diseases in Asia and made recommendations for safer prescribing of nonsteroidal anti-inflammatory drugs (NSAIDs) and low-dose aspirin. METHODS By using a modified Delphi process, consensus was reached among 12 multidisciplinary experts from Asia. Statements were developed by the steering committee after a literature review, modified, and then approved through 3 rounds of anonymous voting by using a 6-point scale from A+ (strongly agree) to D+ (strongly disagree). Agreement (A+/A) by ≥ 80% of panelists was defined a priori as consensus. RESULTS We identified unique aspects of atherothrombotic and musculoskeletal diseases in Asia. Asia has a lower prevalence of degenerative arthritis and coronary artery disease than Western countries. The age-adjusted mortality of coronary artery disease is lower in Asia; cerebrovascular accident has higher mortality than coronary artery disease. Ischemia has replaced hemorrhage as the predominant pattern of cerebrovascular accident. Low-dose aspirin use is less prevalent in Asia than in Western countries. Traditional Chinese medicine and mucoprotective agents are commonly used in Asia, but their efficacy is not established. For Asian populations, little is known about complications of the lower gastrointestinal tract from use of NSAIDs and underutilization of gastroprotective agents. Our recommendations for preventing ulcer bleeding among users of these drugs who are at high risk for these complications were largely derived from Asian studies and are similar to Western guidelines. CONCLUSIONS By using an evidence-based, multidisciplinary approach, we have identified unique aspects of musculoskeletal and atherothrombotic diseases and strategies for preventing NSAID-related and low-dose aspirin-related gastrointestinal toxicity in Asia.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most commonly prescribed agents for rheumatic disorders such as osteoarthritis (OA), rheumatoid arthritis (RA) and ankylosing spondylitis (AS). Despite the known association between NSAID use and gastropathy, however, only around one-third of patients at risk of NSAID-induced gastrointestinal toxicity receive adequate gastroprotection, and as many as 44% of these patients are non-adherent. We review the co-prescription of proton pump inhibitors (PPIs) for the prevention of NSAID-induced gastropathy, with a particular focus on the first fixed-dose NSAID/PPI formulation: ketoprofen/omeprazole modified-release capsules. The ketoprofen/omeprazole fixed-dose combination is available in doses of 100 mg/20 mg, 150 mg/20 mg or 200 mg/20 mg as a single capsule for once-daily administration. Ketoprofen monotherapy has been shown to be generally equivalent to other NSAIDs when used in the treatment of OA. In RA, ketoprofen has demonstrated equivalent efficacy to diclofenac, indometacin, piroxicam, aceclofenac, phenylbutazone, naproxen and flurbiprofen. Studies comparing ketoprofen with ibuprofen and sulindac in patients with RA have, in general, favoured ketoprofen. Studies in AS have generally reported similar efficacy between ketoprofen and phenylbutazone and pirprofen. Prophylaxis with omeprazole is effective for the prevention of gastroduodenal ulcers, maintenance of remission and alleviation of dyspeptic symptoms in NSAID recipients. Omeprazole is well tolerated, and adverse events are generally gastrointestinal in nature. The fixed-dose combination of ketoprofen and omeprazole has demonstrated bioequivalence to the respective monotherapies. The incidence of digestive symptoms and the need for dose reduction was reported to be lower with the combination than with its components. Ketoprofen/omeprazole modified-release capsules are the first fixed-dose NSAID/PPI formulation to be approved. This formulation ensures compliance with the gastroprotective prophylaxis, as whenever the NSAID is taken, the PPI is co-administered. Additionally, the once-daily formulation has the potential to improve adherence to anti-inflammatory therapy.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) confer a gastrointestinal (GI) side effect profile and concerns regarding adverse cardiovascular effects have emerged associated with considerable morbidity and mortality. NSAIDs are highly effective in treating pain and inflammation, but it is well recognized that these agents are associated with substantial gastrointestinal toxicity. Cyclo-oxygenase-2 inhibitors may also reduce the risk for gastrointestinal events, although they may increase cardiovascular adverse events. The selection of an appropriate analgesic or anti-inflammatory agent with or without gastroprotective therapy should be individualized.

A multicenter, double-blind, randomized, controlled phase III clinical trial of chicken type II collagen in rheumatoid arthritis. Arthritis Res Ther 2009; 11:R180. [PMID: 19951408 PMCID: PMC3003530 DOI: 10.1186/ar2870] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2009] [Revised: 09/29/2009] [Accepted: 12/01/2009] [Indexed: 11/19/2022] Open
Abstract
Introduction Chicken type II collagen (CCII) is a protein extracted from the cartilage of chicken breast and exhibits intriguing possibilities for the treatment of autoimmune diseases by inducing oral tolerance. A 24-week, double-blind, double-dummy, randomized, methotrexate (MTX)-controlled study was conducted to evaluate the efficacy and safety of CCII in the treatment of rheumatoid arthritis (RA). Methods Five hundred three RA patients were included in the study. Patients received either 0.1 mg daily of CCII (n = 326) or 10 mg once a week of MTX (n = 177) for 24 weeks. Each patient was evaluated for pain, morning stiffness, tender joint count, swollen joint count, health assessment questionnaire (HAQ), assessments by investigator and patient, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) by using the standard tools at baseline (week 0) and at weeks 12 and 24. Additionally, rheumatoid factor (RF) was evaluated at weeks 0 and 24. Measurement of a battery of biochemical parameters in serum, hematological parameters, and urine analysis was performed to evaluate the safety of CCII. Results Four hundred fifty-four patients (94.43%) completed the 24-week follow-up. In both groups, there were decreases in pain, morning stiffness, tender joint count, swollen joint count, HAQ, and assessments by investigator and patient, and all differences were statistically significant. In the MTX group, ESR and CRP decreased. RF did not change in either group. At 24 weeks, 41.55% of patients in the CCII group and 57.86% in the MTX group met the American College of Rheumatology 20% improvement criteria (ACR-20) and 16.89% and 30.82%, respectively, met the ACR 50% improvement criteria (ACR-50). Both response rates for ACR-20 and ACR-50 in the CCII group were lower than those of the MTX group, and this difference was statistically significant (P < 0.05). The DAS28 (disease activity score using 28 joint counts) values of the two treatment groups were calculated, and there was a statistically significant difference between the two treatment groups (P < 0.05). Gastrointestinal complaints were common in both groups, but there were fewer and milder side effects in the CCII group than in the MTX group. The incidence of adverse events between the two groups was statistically significant (P < 0.05). Conclusions CCII is effective in the treatment of RA and is safe for human consumption. CCII exerts its beneficial effects by controlling inflammatory responses through inducing oral tolerance in RA patients. Trials Registration Clinical trial registration number: ChiCTR-TRC-00000093.

Abstract
PURPOSE The objective was to evaluate the use of German health insurance claims data on medications over the last 10 years by a review of published studies. METHODS PubMed and Scopus were searched for relevant studies published in 1998 through 2007. RESULTS A total of 70 studies were included. Use of these data increased from 32 reports (45.7%) between 1998 and 2005 to 38 (54.3%) over the last 2 years (2006-2007). Over half of the studies (57.1%; n = 40) were written in English and the most frequent research types were health service utilization (51.4%; n = 36) and cost analyses (18.6%; n = 13). In most of the studies (65.7%; n = 46), medication data were linked with other health care utilization claims (e.g. hospitalization data and physicians' outpatient services). Data validity was not taken into consideration in 40.6% (n = 13) of the 32 studies that also analysed hospitalization or physicians' outpatient diagnoses. CONCLUSIONS German health insurance medication claims data were increasingly used for research purposes over the last 10 years. Especially methodological and validation studies are clearly needed.

Abstract
The association between NSAIDs and the presence of upper gastrointestinal (GI) complications is well established. Evidence that acid aggravates NSAID-induced injury provides a rationale for minimizing such damage by acid suppression. Proton pump inhibitors (PPIs) appear to be very effective in treating NSAID-related dyspepsia, and also in healing gastric and duodenal ulcers in patients continuing to receive the NSAID. An analysis of data from comparative studies of PPIs versus ranitidine, misoprostol and sucralfate shows a therapeutic advantage in favour of the PPI. Several studies now confirm the efficacy of co-therapy with PPIs in the short- and long-term prevention of NSAID-induced upper GI injury. PPIs are more effective than histamine H(2)-receptor antagonists at standard dosages in reducing the risk of gastric and duodenal ulcer, and are superior to misoprostol in preventing duodenal but not gastric lesions. However, when balancing effectiveness and tolerance, PPIs may be considered the treatment of choice in the short- and long-term prevention of NSAID-related mucosal lesions. To date, there are only a few published articles dealing with the role of PPIs in the prevention of upper GI complications. Recent epidemiological and interventional studies provide some evidence that PPIs are of benefit. However, more controlled studies using clinical outcomes are needed to establish the best management strategy (PPIs combined with traditional NSAIDs or with cyclo-oxygenase-2 selective inhibitors) especially in patients with multiple risk factors, in patients using concomitant low-dose aspirin, corticosteroids or anticoagulants (high risk group), or in patients with a history of ulcer complications (very high risk group). Furthermore, it should be underlined that Helicobacter pylori infection positively interacts with the gastroprotective effect of PPIs; therefore, the true efficacy of these drugs in preventing NSAID-related ulcer complications should be reassessed without the confounding influence of this microorganism.

Abstract
BACKGROUND & AIMS The primary strategies to reduce the risk of serious gastropathy caused by traditional nonsteroidal anti-inflammatory drugs (NSAIDs) are use of a coxib or concurrent use of a proton pump inhibitor or double-dose histamine-2 receptor antagonist. However, the relative clinical effectiveness of these therapeutic alternatives is understudied. METHODS We studied peptic ulcer hospitalizations in a cohort of Tennessee Medicaid enrollees between 1996 and 2004. To decrease potential "channeling" bias, the study included only new episodes of prescribed NSAID or coxib use and controlled for multiple baseline risk factors for upper gastrointestinal disease. There were 234,010 and 48,710 new episodes of NSAID and coxib use, respectively, with 363,037 person-years of follow-up and 1223 peptic ulcer hospitalizations. RESULTS Current users of NSAIDs with no gastroprotective cotherapy had an adjusted incidence of peptic ulcer hospitalizations of 5.65 per 1000 person-years, 2.76 (95% confidence interval, 2.35-3.23) times greater than that for persons not currently using either NSAIDs or coxibs. This risk was reduced by 39% (16%-56%, 95% CI) for current users of NSAIDs with gastroprotective cotherapy and 40% (23%-54%) for current users of coxibs without such cotherapy. Concurrent users of NSAIDs and proton pump inhibitors had a 54% (27%-72%) risk reduction, very similar to the 50% (27%-66%) reduction for concurrent users of proton pump inhibitors and coxibs. CONCLUSIONS These findings suggest that coprescribing a proton pump inhibitor with an NSAID is as effective as use of a coxib for reducing the risk of NSAID-induced gastropathy.
