A Legacy of Healing: Six Decades of Pharmaceutical Excellence
[INQ. NO. 2504C19] SINSIN PAS, a name that has become synonymous with external pain relief products in Korea, represents the flagship product line of SINSIN Pharm, a pioneering pharmaceutical company established in September 1959.
Founded with the core mission of “Pain Care for the Peoples,” SINSIN Pharm has dedicated over six decades to developing effective pain relief solutions through its specialized Transdermal Drug Delivery System (TDDS) technology.

This dedication has earned the company the honorable title of “Prestigious Manufacturer of the Patch” in the pharmaceutical industry. SINSIN Pharm’s expertise in external medications has allowed it to build a strong market presence, with its SINSIN PAS pain relief patches commanding an impressive 95% market share in Korea.
The company’s commitment to innovation is evident in its extensive product development history. Since its founding, SINSIN Pharm has continuously expanded its product range beyond basic plasters to include specialized patches, hydro gel treatments, cataplasm gel patches, wound care products, and various other external medications.
This product diversification has enabled the company to address multiple healthcare needs while maintaining its focus on pain management solutions.
SINSIN Pharm made history in 1971 by becoming the first Korean pharmaceutical company to export finished pharmaceutical products. This achievement marked the beginning of its global expansion, which now spans over 30 countries across North America, Central and South America, Europe, Middle East, Central Asia, East and South Asia, and Africa.
Notable international customers include major pharmacy chains such as CVS and Walgreen in the USA, Boots Group in the UK, and A.S Watson globally.
Research and Technology Innovation
At the heart of SINSIN Pharm’s success lies its Central Research Center, which serves as the birthplace of the company’s advanced TDDS technology. The research center focuses on developing next-generation drug pipelines that improve medication compliance through innovative delivery methods.
The company’s newest technological advancement is a dual-TDDS that combines the benefits of traditional patches and microneedles with microparticles. This innovative approach allows for the effective loading of poorly soluble drugs, providing both immediate and continuous absorption into the body.
This technology overcomes the lag time issue common in conventional patches, making it applicable to a wider range of therapeutic areas.
Through this research facility, SINSIN Pharm is expanding its development beyond pain management into various medical fields including treatments for dementia, insomnia, urinary incontinence, and rheumatism for both specialty and general medicine markets.

Quality Manufacturing and Global Standards
SINSIN Pharm’s manufacturing excellence is centered at its Sejong Factory, which spans 22,452 square meters and houses two production buildings, an administration building, and subsidiary facilities. The factory operates under strict Good Manufacturing Practice (GMP) certifications, ensuring that all products meet the highest safety and quality standards.

The company also maintains ISO 9001 & ISO 13485 certifications, further demonstrating its commitment to quality management systems. These certifications, along with various CE marks for products like hydro gel pain patches and hydro colloid bands, have facilitated the company’s international expansion.
SINSIN Pharm’s quality policy emphasizes customer satisfaction through superior product quality and service. The company implements comprehensive monitoring at all production stages, from raw material processing to finished product distribution, to ensure consistent quality across its entire product line.
With a legacy spanning over 60 years, SINSIN Pharm continues to advance pain management and healthcare solutions while expanding its global footprint. The company remains committed to its founding principles while embracing innovation, making it a trusted name in pharmaceutical products both in Korea and international markets.
