Beijing Med-Pharm Corp., Plymouth Meeting, is acquiring a minority stake in a Chinese manufacturer of primarily over-the-counter medicines, Sunstone Pharmaceutical Co. Ltd. in Tangshan, Hebei Province.

The alliance extends Beijing Med-Pharm's reach in China because Sunstone has a sales force already promoting to doctors and retail pharmacies. Sunstone products in women's health and pediatrics are the product lines that Beijing Med-Pharm already distributes in China to hospitals.

Currently, Beijing Med-Pharm, a marketing and distribution company, helps U.S. and Western drug companies sell their medicines in China. In the future, Beijing Med-Pharm will be able to help companies manufacture in China, through the joint venture with Sunstone which has manufacturing capabilities.
