Preferred Drug Lists (PDLs) combined with a prior authorization program can effectively cut pharmacy program costs without negatively affecting patient health, as long as the PDLs are based on clinical, evidence-based judgments and non-preferred medications can still be prescribed in a timely manner when necessary. Particularly when combined with the economic leverage of a large purchasing pool, PDLs are a proven strategy to maintain state pharmacy assistance program benefits, including Medicaid, while keeping cost increases below typical double-digit annual figures. NLARx is working with state legislators to craft appropriate PDLs that are based on clinical judgments and involve a minimum of red tape for both patients and medical providers.
