“…NSAIDs according to their ability to inhibit the enzyme cyclooxygenase (COX-1 and 2) are: highly selective NSAIDs (COX-2 inhibitors) -Rofecoxib, Etodolac, Meloxicam, Nimesulid, Celecoxib; NSAIDs with lower COX selectivity -Diclofenac, Piroxicam, and NSAIDs with low COX selectivity -salicylates [14,15]. These drugs successfully suppress the mediators of inflammationmainly prostaglandins (PG), which are important for the occurrence of inflammation and pain: Ibuprofen, Etodolac, Ketoprofen, Ketorolac, Flurbiprofen, Tenoxicam, Meloxicam, Celecoxib and others [16,17,18]. Authors suggest that NSAIDs have an analgesic and an anti-inflammatory effect by reducing the synthesis of arachidonic acid metabolites prostaglandins (PGE2 and PGI2) and thromboxane's (TxA2 and TxB2).…”
