Well sort of. As Adam Fein has noted, most generic drug price increases are a response to shortages, of which we have way too many. In most cases, the price increases can be blamed on drug shortages. "For example, the NADAC per unit for doxycycline hyclate (100 mg tab) increased from 5.6 cents to $3.65 (+6,351%). The increase is most likely due to a nationwide shortage. I presume there’s also an active gray market, as in generic injectables. For context, see Drug Shortages and Gray Market Profiteering."
And the retail price, once again, is not the real price. Again, Adam (drug)channels Mr. Spock in his logical analysis of the gap between retail and acquisition cost.
Adam's columns on pricing are more educational and authoratative than the turgid reports from some members of Congress.
