请教给位大神中试批,验证批,和之后实际生产批批量及设备,试验地点的问题? 我公司现准备报一个6类的片剂,GMP车间过了GMP的设备最小生产量是60kg,为了成本考虑,我中试只想做个几公斤。看了网上大神些说的中试和验证批是可以合到一起的,但是我中试做几公斤的话用的设备只能是小型的设备,不可能是生产用的过了GMP的设备的。那问题就出来了: 1、这样的中试是不是可以不用在GMP车间或者符合GMP的环境下做? 2、这个中试出来的产品是不是不能用来同步验证,也就是中试和验证是不是不能合到一起? 3、验证是必须在GMP车间使用过了GMP的生产设备生产吗或者说必须跟以后生产使用相同的设备吗?那样的话我的验证批批量就太大了 4、这样的中试可以用来做稳定性数据么?还是用验证批做稳定性数据?查看更多 11个回答 . 20人已关注

求纳米级介孔二氧化硅合成方面的解疑? 各位师兄师姐你们好,我想合成水合粒径在200nm以下的MSN,这是我现在采用的方法,原先师兄也是用的这个方法,合成的水合粒径在140nm这样,可是我重复不出来,而且越做越差,因为这位师兄已经毕业有几年了,很多细节都想不起来了,所以希望论坛里的各位大牛可以帮我看一看。 实验方法:将0.96 g 十六烷基三甲基溴化铵 (CTAB)溶解在480 ml H2O中,加入3.5 ml 2M NaOH,80°C下搅拌30 min,然后加入4.67 g正 硅酸乙酯 (TEOS),将此 混合物 在80°C下搅拌2 h,将所得产物离心(7000rpm,10min),用H2O洗涤3次,乙醇洗涤3次,在乙醇-浓盐酸体系中回流5h,重复两次去除模板剂,最后在50℃真空干燥收产物。 ①我慢慢注意到TEOS的滴加速度好像挺重要的,原先我是很慢很慢的滴加,大概在30min加完,可是测得粒径都是微米级的了,最近的一次改为快速滴加 大概6min加完,粒径降到了400nm,我在想要不要把TEOS的滴加速度再加快呢?? ②搅拌速度应该要多快,我之前用的600rpm,得到的产物是白色沉淀,然后用了900rpm(大于900的话容器里会产生大量泡沫),得到的白色产物悬浮在液面上方,这样的话正常吗? ③师兄师姐你们还能看出来我的实验哪里还有问题,或者细节方面需要注意吗? 我知道大家都很忙,能注意到我的问题就很不容易了,路过的师兄师姐伸出援手,我不胜感激!!! 最后祝大家研究生涯能少遇到一些麻烦,mmp 太心累了(我金币好像就这么多了 对不起)查看更多 10个回答 . 10人已关注

China’s Pharmaceutical Future – Both Complex and Growing? China’s Pharmaceutical Future – Both Complex and Growing Posted on June 5, 2015 by FDA Voice By: Howard Sklamberg, Richard Moscicki, M.D., and Alonza Cruse A visit to any one of the cities we visited on this trip – Shanghai, Nanjing and Beijing – would leave anyone marveling at the scale and trajectory of modern China. But it’s not just the sheer size of the population we were struck by. Rather, it was the seemingly tireless dedication to modernity that provided an almost palpable affirmation of what we already knew: that China — its skylines dotted with construction cranes and landscapes crisscrossed by high speed bullet trains — is inextricably connected with our own country’s economy, and increasingly with our agency’s ever-expanding regulatory mission. Howard Sklamberg Howard Sklamberg, FDA’s Deputy Commissioner for Global Regulatory Operations and Policy We traveled to China for a few reasons. First, we wanted to gain more on-the-ground insight into how its drug industry works. We also wanted to offer some helpful perspective to Chinese regulators and drug companies about the Food and Drug Administration Safety and Innovation Act (FDASIA), which passed three years ago and is in the process of being fully implemented. In part, the law gave the FDA new authorities to ensure the safety of the global drug supply chain, in which China plays an enormous part. How enormous? After the United States, China ranks second for the number of FDA-registered drug establishments that the agency regulates, and is the sixth largest provider of drugs and biologics to the U.S. Our itinerary also included a meeting with the Chinese Food and Drug Administration (CFDA) and a tour of a Chinese pharmaceutical manufacturing plant. And if you asked us what the most important by-product of our trip has been, it was these face-to-face conversations with our Chinese counterparts. Specifically, we discussed the responsibilities of firms in the global drug supply chain. These days, the drugs we have in our medicine chests may seemingly come from one company, but the ingredients in them may actually come from numerous companies and countries. China is a major provider of many of the active ingredients in finished drug products Americans rely on every day. Dr. Richard Moscicki Richard Moscicki, M.D., FDA’s Deputy Director, Center for Drug Evaluation and Research We had productive discussions with the Chinese about how seriously we are committed to making sure that everyone in the drug supply chain – from the companies that make the active ingredients to those that provide the packaging –shares in this collective commitment to quality. As we did when we spoke with our counterparts in India, we stressed that we apply the same quality and data integrity standards to all countries shipping drug ingredients into the United States. We delivered the same message to a huge crowd of students at an event hosted by China’s Pharmaceutical University in Nanjing. In our remarks, we set forth our expectations for the delivery of drug quality, saying: “…ideally, our approach will complement the baseline, legal requirement of compliance with the higher bar of firms’ self-interest in being recognized for providing quality products and engaging in a different way with FDA.” While in Nanjing, we had productive discussions with students and stakeholders about FDASIA, quality in contract manufacturing, inspections, regulatory science, and expedited approval pathways that FDA is using to accelerate the process for making novel drugs available to patients. Additionally, we toured a Chinese pharmaceutical facility and met with CFDA to discuss the revision of China’s Drug Administration Law, our own FDASIA implementation, regulatory science matters, as well as continued collaborative activities. We also had a productive roundtable discussion with leaders from 17 prominent Chinese pharmaceutical companies. We addressed pharmaceutical quality, data integrity, and the approval process for generic and innovator drugs. Alonza Cruse Alonza Cruse, FDA’s Acting Director, Pharmaceutical Quality Program, Office of Regulatory Affairs As China’s role on the global stage expands, FDA has significantly increased drug and medical device inspections there, but we need to continue to strengthen our efforts. The Office of Regulatory Affairs and our China office have managed a large number of pharmaceutical inspections. The FDA’s office in China has also strengthened relationships with regulators and helped expand the country’s expertise in regulatory operations. And we have worked with industry and academia to explain our regulations and analyze trends and events that might affect the safety of FDA-regulated products exported from China to the U.S. Given the volume of U.S. trade with China, we are working to expand our presence there to significantly increase the number of inspections we conduct. Staffing increases will allow FDA to enhance its training efforts and technical collaboration with Chinese regulators, industry and others. In fact, in November 2014, we signed a Memorandum of Understanding with the Chinese government that expands our cooperation and will facilitate those staffing increases. FDA’s priorities in China match its global priorities: we work to ensure the safety and efficacy of FDA-regulated products. China’s size and relentlessly expanding economy have an increasingly significant impact on the products that Americans consume, particularly pharmaceuticals. We trust our trip to China added to the growing collaboration between FDA and our counterpart agencies there, ensuring the safety of the pharmaceutical products exchanged between our two nations.
