MUMBAI: WPP’s wholly-owned operating company Grey Healthcare Group has acquired a minority stake in US based PARx Solutions, Inc.

PARx has built a platform designed to support physicians and pharmacies as they manage prescription prior authorization requirements that are put in place by payers for an increasing number of branded prescription drugs.

The company’s web-based portal helps physicians and pharmacies manage prior authorization requirement for prescriptions in a streamlined, user-friendly manner, thereby allowing more patients to receive the medications that their physicians have prescribed. The company is headquartered in Burlington, MA, with offices in Louisville, KY, and San Jose, CA, and was founded in 2008.

This investment continues WPP's strategy of investing in digital and important markets such as the US.
