Abstract

To investigate generic drug price levels in Korea, we conducted a cross-national drug price comparison. Also, it was investigated whether the price level could differ when the price comparison method was changed. Parma Price Information (PPI) and Ministry of Health, Labor and Welfare (MHLW) official gazettes were used for 14 European countries and Japan respectively. Bilateral comparisons with 15 countries were conducted for the top 23 molecules based on health insurance claims data. As a result, the price level of generic drugs in Korea was slightly different depending on the method, but it was overall higher than that of comparison countries. The weighted average price of generics was similar to that of the brand, and none of the launch date, the market share, and the number of competing items appear to affet the drug price level. This study has demonstrated the sensitivity of cross-national drug price comparisons to the methods used, including comparison countries, weights, and price type.
