Top 10 drugs by volume and cost to government

The latest issue of Australian Prescriber listsused in Australia and shows there is an emerging challenge of funding new and expensive drugs.

The lists show the top 10 drugs by daily dose, prescription counts and cost to government.

The most costly drug used in Australia is adalimumab (an immune-system-modifying medicine prescribed for rheumatoid arthritis and Crohn's disease). It cost taxpayers over $300 million in 2014–15.

This is the first time in 20 years that statins (for lowering cholesterol) have not topped the list of most costly drugs to government. Although atorvastatin dropped out of the top 10 by cost to government, it still topped the lists for daily dose and prescription counts.
