It is estimated that 75,000 to 90,000 people in the US have PAH (half of them undiagnosed). The annual costs for various FDA approved drugs for the treatment of PAH is provided below.Interesting that there is such a huge range. Gilead claims that their drug has lower liver toxicity than rivals. Revatio (which actually is just re-branded Viagra) is the cheapest option. Given that the other drugs are priced much higher, Pharmalyst is guessing that it probably is not as effective - let me know if that is not the case because then then this sort of range in pricing can not be easily explained.
PS: Of late, several visitors have found Pharmalyst by typing phrases like "rivaroxaban sales forecast" or "apixaban peak sales" in their Google searches. Pharmalyst has been researching these products and guesstimates of sales will be the subject of a forthcoming post. Stay tuned.
