醫(yī)藥中間體報(bào)價

2017/10/17 17:05:30  作者:騰準(zhǔn)&思域


 

醫(yī)藥中間體,是一些用于藥品合成工藝過程中的一些化工原料或化工產(chǎn)品。

        隨著我國食品藥品監(jiān)管體制的完善健全,外資制藥企業(yè)在中國的業(yè)務(wù)開拓將越來越無法如過去般行使“綠燈特權(quán)”,意味著外資制藥企業(yè)在中國今以后無論申請臨床前的備案或者請示批準(zhǔn)等過程中,也要按規(guī)則“排隊(duì)”的“集體減速”。

       研究預(yù)測:這一切也預(yù)示著中國民族醫(yī)藥產(chǎn)業(yè)正迎來前所未有的,稍縱即逝的短暫“機(jī)遇期”。中國制藥產(chǎn)業(yè)必須抓住這一歷史性機(jī)遇,改變中國制藥研發(fā)企業(yè)博而不專和生產(chǎn)企業(yè)大而不強(qiáng)的局面。預(yù)期未來8年內(nèi)制藥研發(fā)和生產(chǎn)同時達(dá)到兩個戰(zhàn)略目標(biāo):1.仿制藥趕超印度;2.創(chuàng)新藥縮短與歐美發(fā)達(dá)國家差距,甚至局部和部分趕超。為時機(jī)成熟全面趕超創(chuàng)造先決條件和鑄就穩(wěn)固。

  我們收錄了約170個“專利懸崖”的原料藥及部分暢銷原料藥的產(chǎn)品信息、合成路線及對應(yīng)的醫(yī)藥中間體,希望對中國和世界仿制藥的發(fā)展起到一定的推動作用。
