In 2014, a new hepatitis C drug came to market, an innovative treatment offering a cure for a disease that desperately needed one. The price tag: about $84,000 for a 12-week course of treatment, enough to make it the most expensive prescription drug in America.

In the medical world, the halls of insurance offices nationwide and even our nation’s Capitol, all hell broke loose.

The drug, Gilead Sciences Inc.’s Sovaldi GILD, +0.54% remains the most expensive drug in America today, topping a list compiled by drug price comparison website GoodRx. Second on the list is its sister drug Harvoni, which combines Sovaldi with another drug.
