Can both cyclooxygenase-1 (COX-1) and COX-2 medications be combined for patients with osteoarthritis (OA) pain not relieved by high doses of either group alone? What would be a recommended starting combination and doses? Response from Robert Terkeltaub, MD COX-2-selective inhibitor drugs were...
COX-2dogmalignant melanomaIn order to evaluate the potential value of non-steroidal anti-inflammatory drugs (NSAIDs) in the treatment ofcanine malignant melanoma, expression of cyclooxygenase (COX)-1 and COX-2 was determined in 20 cutaneous, nine oral and two ocular malignant melanomas, and in...
皮考布洛芬: 一种COX-1抑制剂、COX-2抑制剂药物,由Torii Pharmaceutical Co., Ltd. (Torii Pharmaceutical Co., Ltd.)公司最早进行研发,目前全球最高研发状态为批准上市,作用机制: COX-1抑制剂(环氧化酶-1抑制剂),COX-2抑制剂(环氧化酶-2抑制剂),治疗领域: 免疫系统疾病
所以只要抑制了COX2酶的活性就可以抑制自生免疫导致的局部炎症(至少是部分)。所以可以说COX2的抑制剂是直接作用于AS这个疾病本身的,并且可以说抑制炎症就是保护关键,同时抑制炎症也是缓解疼痛,所以说很多人就简单的把AS里用的COX2抑制剂认为是“止痛药”!!!然而由于人体中有两种COX酶,一种是COX1,一种是COX2,...
——总说:解热镇痛抗炎药(antipyretic-analgesic and anti-inflammatory drugs)= 非甾体抗炎药(non-steroidal anti-inflammatory drugs,NSAIDs):其为一类具有解热、镇痛,而且大多数还有抗炎、抗风湿作用的药物。其临床效果是:解热镇痛抗炎+抗风湿。并且,本类药物中所有的品种都具有其中的“解热”效果和“镇痛”效果...
Non-steroidal anti-inflammatory drugs (NSAIDs) inhibit the actions of COX by both competitive binding to the arachidonate site and irreversible acetylation of the enzyme (Smith, 1989). At least two isoforms of COX exist, namely COX-1 and COX-2. The so-called housekeeping enzyme COX-1, ...

Aspirin (Acetylsalicylic Acid) 是一种 COX 抑制剂,抑制 COX1 和 COX2 (IC50=5/210 μg/mL),具有选择性、不可逆性和口服活性。Aspirin 也是一种组蛋白去乙酰化酶抑制剂,可上调细胞周期阻滞蛋白 p21。Aspirin 具有抗炎、解热镇痛、抗血小板聚集能多种活性。
所以,对于当前存在或既往发生过胃溃疡或穿孔患者,推荐选择性 COX-2 抑制剂。 选择性 COX-2 抑制剂对 COX-2 和 COX-1 的抑制活性调节在一定的范围内,在消除炎症的同时,维持前列腺素 I2(PGI2)和TXA2之间功能的平衡。 图源:作者...
