Public concern over the safety of generic drugs was further exacerbated by a Congressional investigation into bribery at the FDA by generics companies that found pervasive corruption; the investigation had been spurred by the generics company Mylan, which had hired private investigators based on its beliefs that competitors were getting unfair advantages in getting their generics approved.Mylan itself developed a version of a triamterene/hydrochlorothiazide combination drug after the Dyazide patent expired, and used a different, more stable formulation as well as different dosages of each active ingredient (50 mg hydrochlorothiazide and 75 mg triamterene, compared with Dyazides 25 mg hydrochlorothiazide and 50 mg triamterene) so it had to get approval as a new drug, as opposed to a generic; their product was called Maxzide and was approved in 1984. The higher dose allowed once per day dosing, which Mylan and its marketing partner, Lederle, believed would help it compete against Dyazide, which had $210M in sales in 1983.Mylans patents on the drug were declared invalid in court, and its marketing exclusivity expired in 1987, prompting a rush of generic competition and litigation by two of them, American Therapeutics Inc. and Vitarine Pharmaceuticals, with the FDA. Vitarine, along with Par Pharmaceutical, were two of the companies that Mylan had targeted in its investigation into corruption and it turned out that Par and Vitarine had each used Mylans Maxzide to obtain its bioequivalence data, leading both companies to withdraw its generic competitor to Mylans product. Generics eventually entered the market.
