[交流] Purdue Pharma:如何让一个药独占市场30年? 已有5人参与

盐酸羟考酮是一种常用镇痛药物,通过激动μ阿片受体,缓解中度至重度疼痛。

Purdue Pharma的控释处方于1996年上市,商品名为OxyContin。但这种控释片必须整片服下,如果掰开嚼碎或研磨药片会导致羟考酮的快速释放,患者长期使用会产生耐药性和成瘾性。

2010年,Purdue耗资1亿美元,又推出了所谓的耐挤压新处方,能够降低成瘾性。

2012年OxyContin在美国的销售额达到26.95亿美元(数据来自drugs.com),成为最畅销的成瘾性药物。

2013年4月16日,OxyContin控释处方专利到期(US5508042),FDA也在这一天宣布,不再批准原版的OxyContin仿制药,因为原版的成瘾性太严重。

这样,Purdue依靠新处方专利可以保护至2025年,成功实现独占市场30年。

摘录几个网友的评论:
ralphos: The more profitable you make it to sell and traffic the more abuse there will be. It is self fulfilling.

Merv69: Why is the FDA concerned with safeguarding the patent on OxyContin? Simple answer to make the drug, safer and affordable…crush resistant generic. If Purdue can make it, the generic makers can as well. Besides, there will always be available routes for abuse. What about plain oxycodone? You can still crush that. People are already going that route, same with the new generic Opana ER, its not crush proof like the brand is, so this is the first time in pharmaceutical history people are actually seeking out the generic version.

CentristCoyote: As if more proof was needed that Big Pharma has the government in their back pocket. You’re a fool if you think this will actually help anything except the profit margins of the company that has the patent. And it will make the drug more expensive for a lot longer, for people who legitimately need it for chronic pain.

不知耐挤压的新处方具体是何意思, 指很坚硬,砸不碎?

IT is harder to crush and so harder to abuse.
