Abstract
BACKGROUND: Generic competition is a vital health policy tool used in regulating the pharmaceutical market. Drug group HMG-CoA reductase (3-hydroxy-3-methyl-glutaryl-coenzyme-A reductase) inhibitors, widely known as "statins," was the first drug group in Hungary in which generic prescriptions became mandatory. Our aim is to analyze the changes in the retail and wholesale margins through the generic competition regarding "statins". METHODS: Data was derived from the nationwide pharmaceutical database of the Hungarian National Health Insurance Fund Administration, the only health care financing agency in Hungary. We observed the turnover data regarding the HMG-CoA-reductase inhibitor "statins" from 2010 through 2019. As the drugs under review have a fixed price point in Hungary, we effectively calculated the margins. RESULTS: In 2010, the consumer expenditure of statins was 30.7 billion HUF ($148 million), which decreased by 59%, to 12.5 billion HUF ($42.9 million) in 2019. In 2010, the annual health insurance reimbursement of statins was 23.7 billion HUF ($114 million), which underwent a 63% decrease to 8.6 billion HUF ($29.7 million) in 2019. In 2010, the DOT turnover was 287 million days, and it increased to above 346 million days for 2019, which reflects a 20% increase over the past nine years. The monthly retail margins decreased from 334 million HUF ($1.6 million), (January, 2010) to 176 million HUF ($0.61 million), (December, 2019). The monthly wholesale margins decreased from 96.3 million HUF ($0.46 million), (January, 2010) to 41.4 million HUF ($0.14 million), (December, 2019). The most significant downturn in margins was due to the introduction of the first two blind bids. The combined DOT turnover in reference to the examined 43 products consistently increased. CONCLUSIONS: The decline in retail and wholesale margin and in health insurance expenditures was largely due to a reduction in the consumer price of generic medicines. DOT turnover of statins also increased significantly.
