In the US the price ordinarily drops to about 40-50 % of the original. In Taiwan, however, the local companies that manufacture generic drugs after patents expire still ask for 80 % of the original prices. If this can be lowered to 40-60 %, the NHICSA estimates that NT $ 9.9-19.9 billion could be saved each year.
以美國而言，藥價會降到原來的 4 到 5 成；反觀台灣，過了專利期、由國內藥廠製造的「學名藥」仍索價達原藥價 8 成，若能降至原廠給付的 4 到 6 成，督保盟估計，一年至少可省下 99 億到 199 億元的支出。
