Think of Voltaren® Gel as “ibuprofen in a gel.” (It’s actually diclofenac, but ibuprofen is a much more familiar drug name in North America, where the product is still fairly new, and available only with a prescription in the US.) It’s a topical anti-inflammatory medication,NSAID“Non-steroidal anti-inflammatory drug,” usually pronounced “en-sed.” and FDA-approved to treat osteoarthritis in “joints amenable to topical treatment, such as the knees and those of the hands.” The evidence shows that it “provides clinically meaningful analgesia.”1 This is an appealing treatment idea that actually works reasonably well: what a pleasure to be able to say that!2
Schematic showing that when a cell membrane is injured the arachidonic acid pathway is activated to initiate the local inflammatory response through the production of prostaglandins, thromboxanes, and leukotrienes. Their activation requires the enzymes COX and LOX. The NSAIDs can block COX action and thereby prevent the formation of the COX-derived inflammatory mediators. 5-HPETE = 5-hydroperoxyeicosatetraenoic acid; LTC4 = leukotriene C4; PGE2 = prostaglandin E2; PGF2 = prostaglandin F2; PGI2 = prostacyclin; TXA2 = thromboxane.
About “tendinitis” versus “tendonitis”: Both spellings are considered acceptable these days, but the first is technically correct and more formal, while the second is an old misspelling that has only achieved respectability through popular use. The word is based on the Latin “tendo” which has a genitive singular form of tendinis, and a combining form that is therefore tendin. (Source: Stedmans Electronic Medical Dictionary.) BACK TO TEXT
