Prescription Drug Use and Spending Report

Key Findings

• Overall prescription drug utilization declined as the average cost per prescription increased.
• Ten therapeutic classes of drugs, which include Immunosuppressants, Hormones & Synthetic Substances, and Cardiovascular Agents, accounted for over 90% of pharmacy expenditures each year.
• Immunosuppressants, a class of drugs that inhibit immune system activity and are used to treat autoimmune diseases, accounted for the largest portion of spending. The top three drugs by expenditures during the five-year period were Humira, Stelara, and Enbrel, all Immunosuppressants.
• The most frequently prescribed drugs (i.e., highest volume) during the five-year period were Atorvastatin Calcium and Lisinopril, both Cardiovascular Agents. Atorvastatin Calcium is used to treat high cholesterol and triglyceride levels to reduce the risk of heart and blood vessel problems; Lisinopril is used to treat high blood pressure and heart failure.
