Core Functions of Crisaborole

Crisaborole is a non-steroidal topical ointment primarily indicated for the treatment of mild-to-moderate atopic dermatitis (eczema) in patients aged 2 years and older. Its therapeutic effect is mediated through selective inhibition of phosphodiesterase-4 (PDE-4), an enzyme responsible for promoting inflammatory responses. By suppressing PDE-4 activity, Crisaborole reduces the release of pro-inflammatory cytokines, thereby alleviating skin inflammation, pruritus, and erythema. Notably, it avoids the adverse effects associated with corticosteroids, such as skin atrophy, making it a safer long-term option for pediatric and adult populations.

The advantage of Sinoway’s Crisaborole

1. Cost and Production Efficiency:

China’s globally competitive active pharmaceutical ingredient (API) supply chain and economies of scale enable significant cost reductions, enhancing affordability and accessibility.Besides, robust pharmaceutical and chemical infrastructure accelerates localized production of generic versions, streamlining time-to-market.

2. Technological and Quality Standards

Chinese manufacturers adhere to stringent bioequivalence assessments and international certifications, ensuring parity with originator drugs in quality and efficacy. Meanwhile, adoption of sustainable synthesis technologies optimizes Crisaborole production while minimizing environmental impact.

3. Market Potential and Patient Base

The world’s vast eczema patient population (over 30 million) and growing parental preference for non-steroidal therapies position Crisaborole as a high-growth segment in dermatology.
