《哈奇-瓦克斯曼法案》激励制药商对即将失去专利保护的现有产品进行重新配制,以扩大营销专营权并维持高价格。抗抑郁药的重新配制尤其常见。为了确定抗抑郁药物重新配方的使用是否带来益处,我们检查了谁使用重新配方,并比较了重新配方使用者和原始配方使用者的用药持续时间和接受符合指南的药物治疗持续时间的可能性。我们发现一些抗抑郁药使用者亚组受益的证据,尽管不同配方的益处各不相同。
The Hatch-Waxman Act provides pharmaceutical manufacturers an incentive to introduce reformulations of existing products about to lose patent protection in order to extend marketing exclusivity and maintain high prices. Antidepressant reformulations are particularly common. To determine whether antidepressant reformulation use confers benefits, we examine who uses reformulations, and compare medication continuation and the likelihood of receiving guideline-consistent pharmacotherapy duration among reformulation and original formulation users. We find some evidence of benefit for subgroups of antidepressant users, although benefits vary across reformulations.
