Generic Drug Competition Lowers Prices: FDA Analysis
A new FDA analysis based on two sources shows that greater generic drug competition is linked to lower generic drug prices. An FDA statement says the analysis updates and expands on a 2005 analysis and includes two different sources of wholesale drug prices. It looked at all drug products that had generic entry between 2015 and 2017 and showed that as competition increases, generic drug prices decline, the statement says.
For products with a single generic producer, the generic average manufacturer prices (AMP) reported to the Centers for Medicare and Medicaid Services was 39% lower than the branded drug price before generic competition, compared to a 31% reduction using invoice-based drug prices.
With two competitors, AMP data show generic prices are 54% lower than the branded drug before generic competition, compared to a 44% reduction using invoice-based prices. And with four competitors, AMP data show generic prices are 79% less than the branded price before generic drug entry, compared to a 73% reduction using invoice-based prices.
With six or more competitors, generic prices using both AMP and invoice-based drug prices show reductions of more than 95% compared to branded prices before generic entry.
