The Salonpas Pain Relief Patch and Salonpas Arthritis Pain patches are manufactured using what Hisamitsu calls "comfort stretch" technology that provides effective pain relief while allowing patients to maintain daily activities and, an alternative for those who prefer to avoid the use of oral OTC pain-relief medication for minor aches and pains. The company differentiates its products from oral medications because the active ingredients in Salonpas patches are absorbed through the skin and go directly to the site of the pain.
FDA approval
In February 2008 the FDA approved a New Drug Application covering Salonpas Pain Relief Patch and Salonpas Arthritis Pain, topical pain-relieving patches. These patches contain recognized analgesic ingredients called counterirritants, which when applied to the skin, diminish pain signals under areas to which they are administered. To date, the Salonpas Pain Relief Patch and Salonpas Arthritis Pain patch are the only external analgesic patches subject to an approved NDA and sold into the over-the-counter health care market. The effectiveness of the Salonpas Pain Relief Patch and Salonpas Arthritis Pain patch have been established in a randomized controlled trial that was performed by Hisamitsu employees. The study, which was published in 2010, involved 208 adults with mild to moderate muscle strain. In the study, the Salonpas patch was found to provide significantly greater pain relief compared to a placebo patch, and the rates of adverse events were similar in the Salonpas and placebo groups.
