Hisamitsu: The Salonpas Patch on the World’s Aching Backs

TYO:4530

Reach for a medicated patch to soothe an aching back or shoulder almost anywhere in the world, and there’s a good chance it’s a Salonpas. Behind that humble adhesive patch is Hisamitsu, a Japanese company that turned mastery of delivering medicine through the skin into the world’s number-one over-the-counter pain-relief patch.

The world’s best-selling pain patch

Hisamitsu, whose roots stretch back to 1847, is the maker of Salonpas — recognized by Euromonitor as the brand with the world’s number-one market share in OTC topical analgesic patches for years running. The medicated patch, applied directly to a sore spot, delivers pain relief steadily through the skin, and Salonpas has become a global household name, increasingly visible on US pharmacy shelves and beyond.

Mastery of the patch

Hisamitsu’s real expertise is transdermal technology — the science of delivering drugs through the skin via patches. Doing it well requires precise control of adhesion, drug release, and skin comfort over hours of wear. That deep, specialized capability underpins Salonpas and a broader range of prescription and OTC patches, and it is far harder to replicate than a simple adhesive bandage. As the world ages and seeks non-pill pain relief, demand for trusted topical analgesics grows.

Why it matters for global partners and investors

• Investors get a focused consumer-health play on a globally trusted brand with steady demand and international expansion runway, especially in the US.
• Retail and pharmacy partners benefit from a category-leading, recognizable brand in OTC pain relief.
• The growth to watch is overseas expansion and the broader rise of transdermal drug delivery as a non-oral treatment route.
