Combination Methyl Salicylate and Menthol

There are very limited published clinical data on the use of MS in conjunction with menthol, despite the widespread use of this analgesic combination. In a placebo-controlled trial, an occlusive topical patch containing 10% MS and 3% l-menthol (Salonpas/Hisamitsu America) was found to produce significantly greater pain relief (40%) after initial application compared with placebo in adults with mild-to-moderate muscle strain. Pain relief was present during the 8 hours in which the patch was in contact with the skin; after removal of the patch, pain control dissipated. Salonpas patches are the first and only topically applied medication to receive FDA approval for the temporary relief of mild-to-moderate aches and pains of muscles and joints associated with arthritis, back pain, strains, bruises, and sprains.[14] Side effects in the active treatment group were comparable with those seen in patients who had received the placebo patch.[46]
