Washington Prescription Drug Program (WPDP)

We ensure the value of prescription drug purchasing by the state.

The Washington Prescription Drug Program provides prescription drug oversight for the residents of Washington.

Goals

Our goal is to make sure Washington prescription drug consumers get healthier medications at lower prices. We do this through the following two methods: 

  • Our evidence-based preferred drug selection process for the Washington Preferred Drug List (PDL).
  • Pooled purchasing through ArrayRx Solutions, formerly the Northwest Prescription Drug Consortium.
