Willink Pharma (绿叶制药, Luye Pharma) is a leading Chinese pharmaceutical company specializing in innovative drug delivery technologies and central nervous system therapeutics. Founded in 1994 and headquartered in Yantai, Shandong Province, China, Willink Pharma has developed a robust portfolio of extended-release formulations and transdermal delivery systems for the treatment of neurological and psychiatric disorders. The company's focus on advanced drug delivery, particularly its proprietary LypoBridge™ technology, positions it as a key player in China's evolving pharmaceutical landscape[rotigotine][1].
The company's Parkinson's disease program centers on rotigotine, a dopamine agonist delivered via transdermal patch, which provides continuous dopaminergic stimulation and addresses the significant challenge of motor complications in Parkinson's disease management. Willink Pharma's rotigotine product (marketed as Nourianz® in the US and Nupora® in China) represents one of the few locally-developed transdermal neurological therapies in China, demonstrating the company's commitment to addressing unmet medical needs through innovative delivery technologies.

Willink Pharma operates as part of China's rapidly expanding pharmaceutical sector, which has seen substantial growth over the past two decades. The company has established manufacturing facilities meeting international standards, with multiple facilities certified by US FDA, EU EMA, and Chinese NMPA. This manufacturing capability enables both domestic Chinese market supply and international export opportunities[chinese_biotech].
Parkinson's disease is the second most common neurodegenerative disorder globally, affecting approximately 10 million people worldwide. In China, the prevalence is substantial, with estimates suggesting over 3 million patients. The disease burden is expected to increase significantly as China's population ages, making effective therapies increasingly important[parkinson_treatment].
Parkinson's disease involves progressive degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to the characteristic motor symptoms:
The cardinal motor symptoms of Parkinson's disease include:
These symptoms result from progressive loss of dopaminergic neurons in the substantia nigra, which project to the striatum and regulate movement control[dopamine_agonists].
Parkinson's disease also involves numerous non-motor symptoms:
Long-term Parkinson's disease treatment is complicated by motor complications:

Willink Pharma's proprietary LypoBridge™ technology enables extended-release drug delivery through advanced formulation approaches:
The LypoBridge™ platform uses lipid-based delivery systems to control drug release:
This technology is particularly valuable for CNS drugs requiring consistent plasma concentrations to maintain therapeutic effect[extended_release][2].
LypoBridge™ offers several advantages:
Willink Pharma has developed advanced transdermal delivery capabilities:
Transdermal administration offers unique benefits:
