With 止痛贴 gaining popularity in the global healthcare market, OEM clients are seeking ways to develop effective, safe, and export-ready products. This guide walks you through the essentials of dosage forms, ingredient selection, and international compliance for a competitive OEM strategy.

✅ 1. Choosing the Right Dosage Form

Each patch type offers unique benefits and fits specific markets:

• Hydrogel-based: Cooling, breathable—preferred in Japan and Southeast Asia.

• Rubber plaster (traditional): High adhesion and warming effect, suited for chronic pain relief.

• Self-heating patches: Use iron powder to generate warmth and stimulate circulation.

• Non-woven coated types: Affordable and mass-producible, popular in Europe and North America.

Select based on end-user habits and regional preferences.

🌿 2. Ingredient Strategy for Noticeable Relief

An effective formula should deliver quick results and user comfort:

• Pain relief actives: Capsaicin, methyl salicylate, 薄荷醇.

• Herbal blends: Mugwort, angelica, dong quai—good for TCM-style products.

• Soothing agents: Lavender, tea tree—enhance sensory and emotional experience.

For Western markets, label claims like “NSAID-free” and “botanical-based” boost appeal.

🌍 3. Export Compliance & Documentation

• U.S.: Most pain patches fall under OTC monograph regulations by the FDA.

• EU: Require MDR compliance and CE certification with strong labeling accuracy.

• Japan/Korea: Expect rigorous patch tests and INCI-compliant ingredient lists.

OEM factories should have GMP and ISO13485 certifications to meet global expectations.
