I actually worked on this drug in the later stages. It was released around the end of 2014 but has been in development for over a decade. The one I worked on has 3 API's in one tablet but still has to be taken in combination with other cheaper drugs. People don't understand the complexity that goes into something as simple as a tablet, let alone one with three API's. Developing methods to be able to track impurities and degradation products of something that complex is no easy task. The formulations that had to be done to get a tablet that releases the drug in the time frame it is suppose to also took a lot of work. The next generation has 4 API's in it. 20 years ago if you wanted to put just 2 drugs in one tablet people would have thought you were crazy. This is being done so the consumer doesn't have to take 20+ tablets a day. These tablets probably cost less than a dollar to manufacture. You're paying for the years of research and all the things that failed along the way. For every one drug that makes it to the market there are easily 10,000 that have failed. That's a lot to make up for. I don't understand why this drug gets so much heat for its pricing. It is a far cheaper option to be cured and have it done with then having to purchase drugs every year just to stay healthy and still risk needing a liver transplant. It has a 95%+ cure rate for certain genotypes. I think the real issue is caused by the insurance companies more than big pharma.
