Description

Trolamine salicylate is an organic compound or a salt formed between triethanolamine and salicylic acid. Triethanolamine neutralizes the acidity of the salicylic acid. It is a topical analgesic used for temporary relief of minor pain associated with arthritis, simple backache, muscle strains, sprains, and bruises. Unlike other topical analgesics, trolamine salicylate has no distinct odor which improves patient acceptability 2. It also displays low systemic absorption upon dermal or topical administration 3 and has low skin irritant properties 4. As with other salicylates, trolamine salicylate is an inhibitor of cyclo-oxygenase (COX) enzymes with no reported selectivity towards a specific enzyme isoform. Trolamine salicylate serves as an active ingredient in topical over-the-counter products for temporary management of mild to moderate muscular and joint pains.

Pharmacology

Indication

Indicated for the temporary relief of aches, and pains of muscles and joints associated with backache, lumbago, strains, bruises, sprains and arthritic or rheumatic pain, pain of tendons and ligaments 6.

Pharmacodynamics

Trolamine salicylate is a salicylate that inhibits cyclo-oxygenase (COX) enzymes responsible for generating pro-inflammatory factors such as to induce pain and inflammation. It is thought to mediate its analgesic effect through inhibition of COX-2 enzyme, which is an induced enzyme responsible for inflammatory responses and pain in muscle and joint disorders. By inhibiting fatty acid COX enzyme, trolamine salicylate inhibits the production of prostaglandins and thromboxanes in inflammatory cells involved in generating pain and inflammation 5. It thereby works to temporarily reduce mild to moderate pain. In subjects with muscle soreness from exercise, administration of topical trolamine salicylate was associated with reduced duration and severity of muscule soreness compared to placebo 2. In subjects with osteoarthritis in hands, trolamine salicylate cream was shown to be effective in achieving temporary relief of minor pain and stiffness 1.

Mechanism of action

Inflammation and tissue damage in different conditions including arthritis, bursitis, joint disorder, bruises, and strains or sprains of muscle origin, induce mild to moderate pain and are associated with increase prostaglandin synthesis 5. This is thought to be a result of COX-2 enzyme induction. COX-2 is induced in inflammatory cells in case of cell injury, infection or activation from inflammatory cytokines such as interleukin (IL)-1 and tumor necrosis factor (TNF)-α. Upon activation, COX-2 produces prostanoid mediators of inflammation such as prostaglandins and thromboxanes 5. Trolamine salicylate mediates its analgesic effect by inhibiting the production of inflammatory mediators that sensitize nociceptive nerve endings and generate pain 5.
