Nitrofurantoin was discovered in the 50s, and generic versions are widely available. But this particular change is more complex. First, the manufacturer is producing an oral suspension, which is substantially more expensive than equivalent generic tablet formations. Second, the price increase seems to have come about due to a shortage in supply, in turn due to unspecified "new rules on impurities from the FDA". So I guess there's some argument that a limited number of suppliers in the market has pushed up the cost. But the drug is still 3-4 times more expensive than the equivalent oral formulation in the UK, so the definite impression here is "absolutely shameful price-gouging".
