Pharmaceutical companies Wyeth and Pfizer Inc. were sued by Nevada''s attorney general for alleged deceptive trade practices in selling four hormone therapy drugs, according to the Associated Press. The lawsuit filed Tuesday in Clark County District Court in Las Vegas contends that Nevada consumers and doctors were misled about the safety and efficacy of Premarin, Prempro and Premphase, sold by Wyeth, and Pfizer''s Provera. The suit contends that Wyeth and Pfizer intentionally minimized the risks and exaggerated the benefits of their hormone therapy drugs, resulting in over-prescribing and a dramatic increase in hormone-positive breast cancers in post-menopausal women. The state is working with two private law firms that have been litigating similar cases for several years. One of those cases led to a $58 million award that Wyeth was ordered to pay three Nevada women who claimed that Prempro caused their breast cancer. Wyeth appealed that verdict.
