非甾体抗炎药的新进展

<正> 近年来,越来越多的抗炎镇痛新药已经用于风湿病的治疗,这些药物临床作用的基础在于抑制前列腺素的合成,然而它们在不同的疾病中有不同的作用。由于它们精细的作用方式不尽相同,其药理作用和毒性也差异很大,特别是不同病人对不同的非甾体抗炎药(NSAID)有完全不同的反应。因此,试制多种药物以适应治疗的个体化,对各种病人寻求最有效的治疗方案是很有价值的,同时必须记住这些药物

非甾体抗炎药(NSAIDs)是临床上广泛应用的一类具有解热镇痛,大部分还有抗炎、抗风湿作用的药物.非甾体抗炎药的不良反应如消化道损害,肝肾损害发生率较高,针对这些不良发应开发了许多新的药物,如非甾体缓(控)释剂、非甾体和胃肠道保护剂的复方制剂、NO型非甾体药物等.近期研究还发现,非甾体抗炎药除了传统的治疗作用外,对阿尔茨海默病、早产、癌症等疾病均有预防或治疗作用,其临床应用不断扩展.本文就非甾体抗炎药的临床研究新进展作一综述.     

非甾体抗炎药物在骨性关节炎中的应用

骨性关节炎是老年人中常见、多发的慢性进行性骨关节疾病,主要临床表现为缓慢发展的可使活动受限的关节疼痛、僵硬和肿胀,严重的能导致关节功能障碍.非甾体抗炎药物是目前治疗骨性关节炎等关节炎性疾病的最常用药物,作用机制为抑制环氧化酶活性、阻断该酶催化花生四烯酸转化为炎性物质前列腺素,从而发挥止痛、消炎作用.非甾体抗炎药物分为非选择性环氧化酶抑制剂和选择性环氧化酶-2抑制剂两类,应用广泛,但也存在多种不良反应,故选择用药时要严格掌握适应证,合理用药.     

Upper gastrointestinal disorders induced by non-steroidal anti-inflammatory drugs

Aims: We examined the characteristics of upper gastrointestinal disorders induced by non-steroidal anti-inflammatory drugs (NSAIDs). Methodology: The questionnaire investigation was performed over a five year period. Results: A study was performed on 354 patients (161 men and 193 women with mean ages of 66.0 and 70.7 years, respectively) who developed NSAIDs associated upper GI disorders: 21 patients had AGML, 212 had gastric ulcer, 63 had duodenal ulcer, 17 had gastroduodenal ulcers and 41 other cases. About 75 % of patients received NSAIDs for orthopedic conditions. Sixty percent of gastric disorders induced by NSAIDs affected the antrum or angulus of the stomach. The incidence of disorders of the gastric antrum was significantly higher in women than in men whilst the incidence of disorders on the gastric angulus was significantly higher in men than in women (p < 0.05). The proportion of patients with abdominal pain was significantly lower in patients over 65 years old than in those under 65 years old, and the proportion of patients with hematemesis or melena was significantly higher in patients over 80 years old than in those under 80 years old (p < 0.05). The time taken to achieve the healing stage was significantly longer in patients with greater than 3 months NSAIDs ingestion compared to patients that had received NSAIDs for less than 3 months (p < 0.05). Conclusions: Patients 65 years old and over with continuous NSAIDs use had asymptomatic ulcers, and patients 80 years old and over had hemorrhagic ulcers.

An update on the efficacy of non-steroidal anti-inflammatory drugs in Alzheimer's disease

Several epidemiological studies suggest that long-term use of non-steroidal anti-inflammatory drugs (NSAIDs) may protect against Alzheimer's disease (AD), especially for patients carrying one or more ?4 allele of the apolipoprotein E. The biological mechanism of this protection is not completely understood and may involve inhibition of COX activity, inhibition of β-amyloid_1-42 (Aβ42) production and aggregation, inhibition of β-secretase activity, activation of PPAR-γ or stimulation of neurotrophin synthesis. Unfortunately, long-term, placebo-controlled clinical trials with both non-selective and COX-2 selective NSAIDs in AD patients produced negative results. A secondary prevention study with rofecoxib in patients with mild cognitive impairment and a primary prevention study with naproxen and celecoxib in elderly subjects with a family history of AD were also negative. All these failures have diminished the hope that NSAIDs could be beneficial in the treatment of AD. It is hypothesized that the chronic use of NSAIDs may be beneficial only in the normal brain by inhibiting the production of Aβ42. Once the Aβ deposition process has started, NSAIDs are no longer effective and may even be detrimental because of their inhibiting activity on activated microglia of the AD brain, which mediates Aβ clearance and activates compensatory hippocampal neurogenesis.     

结肠直肠癌和非甾类消炎药(英文)

Non-steroidal anti-inflammatory drugs ( NSAIDs) can prevent or reduce the occurrence of colorectal cancers . Anti-carcinogenic properties of NSAIDs have been demonstrated in epidemiological studies of humans and experimental animals. In addition, clinical studies of familial adenomatous polyposis and sporadic adenomas have demonstrated that NSAIDs induce regression of colorectal adenomas and prevent formation of these tumors. NSAIDs thus induce early disruption of the adenoma-carcinoma sequence and may mainly suppress subsequent cancer formation at adenoma stage. The mechanism of the anti-carcinogenic effect of these drugs is not known, but results of most studies support that cyclooxygenase-2 (an inducible isoform of prostaglandin synthetase, COX-2) is a major target of NSAIDs in this effect. Recent immunohistochemical studies have revealed that COX-2 is expressed not in tumor cells but in interstitial cells of colonic adenomas. Accordingly, NSAIDs may exhibit anti-carcinogenic property through the inh

Comparative study of anti-inflammatory activity of some branded generic and generic non-steroidal anti-inflammatory drugs

Generic drugs play a very important role in health care. A study was undertaken to ascertain the equality or inequality between generics and branded generics. NSAIDs are the most commonly used drugs. So these drugs were chosen for the study. Selected branded generic and generic products of ibuprofen, nimesulide, and diclofenac sodium were tested by oral administration of their suspensions to different groups of rats. Freshly prepared drug suspensions equivalent to doses of 40, 10, and 5?mg/kg of ibuprofen, nimesulide, and diclofenac sodium, respectively, were administered orally to the rats and anti-inflammatory activity was measured by the carrageenan-induced rat paw edema model employing Zeitlin’s apparatus to measure the paw thickness. Statistical analysis by t-test, of the activity at the point of maximum difference indicated that with respect to anti-inflammatory activity generic ibuprofen and generic diclofenac sodium are better than branded generic ibuprofen and branded generic diclofenac sodium, respectively, and generic nimesulide is similar to branded generic nimesulide. All the products studied meet the Pharmacopoeial requirements. Hence it may be concluded that branded generic and generic NSAIDs, tested in this study, are of the same efficacy and inter-changeability among branded generics, and switching between branded generics and generics would not result in any difference in efficacy.
