Purdue Pharma:如何讓一個(gè)藥獨(dú)占市場(chǎng)30年? 已有5人參與
|
|
鹽酸羥考酮是一種常用鎮(zhèn)痛藥物,通過激動(dòng)μ阿片受體,緩解中度至重度疼痛。 Purdue Pharma的控釋處方于1996年上市,商品名為OxyContin。但這種控釋片必須整片服下,如果掰開嚼碎或研磨藥片會(huì)導(dǎo)致羥考酮的快速釋放,患者長(zhǎng)期使用會(huì)產(chǎn)生耐藥性和成癮性。 2010年,Purdue耗資1億美元,又推出了所謂的耐擠壓新處方,能夠降低成癮性。 2012年OxyContin在美國的銷售額達(dá)到26.95億美元(數(shù)據(jù)來自drugs.com),成為最暢銷的成癮性藥物。 2013年4月16日,OxyContin控釋處方專利到期(US5508042),F(xiàn)DA也在這一天宣布,不再批準(zhǔn)原版的OxyContin仿制藥,因?yàn)樵娴某砂a性太嚴(yán)重。 這樣,Purdue依靠新處方專利可以保護(hù)至2025年,成功實(shí)現(xiàn)獨(dú)占市場(chǎng)30年。 摘錄幾個(gè)網(wǎng)友的評(píng)論: 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. [ Last edited by 癡夢(mèng)瀟湘 on 2013-4-17 at 17:07 ] |
