PART 3 INDUSTRIAL PHARMACYUnit 11 Tablets (The Pharmaceutical Tablets Dosage Form)Role in TherapyThe oral route of drug administration is the most important method of administering drugs for systemic effects. Except in cases of Insulin therapy,the parenteral route is not routinely used for self-administration of medications. The topical route of administration has only recently been employed to deliver drugs to the body for systemic effects,with two classes of marketed products: Nitroglycerin硝酸甘油酯for the treatment of angina心绞痛and scopolamine莨菪胺for the treatment of motion sickness晕动病,指晕车、晕船等. Other drugs are certain to follow,but the topical route of administration is limited in its ability to allow effective drug absorption for systemic drug action. The parenteral route of administration is important in treating medical emergencies in which a subject is comatose昏迷的or cannot swallow,and in providing various types of maintenance therapy for hospitalized patients. Nevertheless,it is probable that at least 90 % of all drugs used to produce systemic effects are administered投药,给药by the oral route. When a new drug is discovered,one of the first questions a pharmaceutical company asks is whether or not drug can be effectively administered for its intended effect by the oral route. If it cannot,the drug is primarily relegated to被降级到administration in a hospital setting or physician's office. If patient self- administration cannot be achieved,the sales of the drug constitute only a small fraction of what the market would be otherwise. Of drugs that are administered orally,solid oral dosage forms represent the preferred class of product. The reasons for this preference are as follows. Tablets and capsules represent unit dosage forms in which one usual dose of the drug has been accurately placed. By comparison相比之下,liquid oral dosage forms,such as syrups,suspensions,emulsions,solutions,and elixirs,are usually designed to contain one dose of medication in 5 to 30 ml. The patient is then asked to measure his or her own medication using a teaspoon,第三部分工业药剂学第11单元药片(医药的片剂剂型)在治疗中的作用口服给药途径是通过给药获得全身作用效果中最重要的方法。

Unit 13 Sterile ProductsSterile ProductsSterile products are dosage forms of therapeutic agents that are free of viable microorganisms. Principally,these include parenteral,ophthalmic,irrigating preparations. Of these, and parenteral products are unique among dosage forms of drugs because they are injected through the skin or mucous membranes into internal body compartment. Thus,because they have circumvented the highly efficient first line of body defense,the skin and mucous membranes,they must be free from microbial contamination and from toxic components as well as possess an exceptionally high level of purity. All components and processes involved in the preparation of these products must be selected and designed to eliminate,as much as possible,contamination of all types,whether of physical,chemical,or microbiologic origin.Preparations for the eye, though not introduced into internal body cavities,are placed in contact with tissues that are very sensitive to contamination. Therefore,similar standards are required for ophthalmic preparations).Irrigating solutions are now also required to meet the same standards as parenteral solutions because during an irrigation procedure,substantial amounts of these solutions can enter the bloodstream directly through open blood vessels of wounds or abraded mucous membranes. Therefore,the characteristics and standards presented in this chapter for the production of large-volume parenteral solutions apply equally to irrigating solutions. Sterile products are most frequently solutions or suspensions,but may even be solid pellets for tissue implantation. The control of a process to minimize contamination for a small quantity of such a product can be achieved with relative ease. As the quantity of product increases,the problems of controlling the process to prevent contamination multiply. Therefore,the preparation of sterile products has become a highly specialized area in pharmaceutical processing. The standards established,the attitude of personnel,and the process control must be of a第13 单元无菌产品无菌产品无菌产品是不含微生物活体的治疗剂剂型,其主要包括非肠道用的、眼用的和冲洗用的制剂。
制药工程英语作文Pharmaceutical Engineering。
Pharmaceutical engineering is a branch of engineering that deals with the design, development, and production of drugs and pharmaceutical products. It is amultidisciplinary field that combines the principles of chemical engineering, biochemistry, and pharmacology. The objective of pharmaceutical engineering is to develop safe, effective, and affordable drugs that can be used to treat various diseases.The process of drug development begins with the identification of a potential drug target. This can be a protein, enzyme, or other biological molecule that is involved in the disease process. Once a target has been identified, researchers use various techniques to design and synthesize compounds that can interact with the target and modify its activity.The next step in drug development is preclinical testing. This involves testing the safety and efficacy of the drug in animal models. If the results of preclinical testing are promising, the drug can move on to clinical trials. Clinical trials are conducted in humans and are designed to test the safety and efficacy of the drug in a controlled setting.Pharmaceutical engineers are involved in all aspects of drug development, from the initial design and synthesis of compounds to the production and distribution of the final product. They work closely with chemists, biologists, and pharmacologists to develop new drugs and improve existing ones.One of the key challenges in pharmaceutical engineering is ensuring the safety and efficacy of drugs. This requires a thorough understanding of the biological processes involved in disease and the mechanisms of action of drugs. It also requires the use of advanced analytical techniques to monitor the quality and purity of drugs throughout the production process.Another challenge in pharmaceutical engineering is the cost of drug development. Developing a new drug can cost billions of dollars and take many years to complete. Pharmaceutical engineers must work to optimize the drug development process and reduce costs without compromising safety or efficacy.Despite these challenges, pharmaceutical engineering plays a critical role in improving human health. The development of new drugs has led to significant advances in the treatment of diseases such as cancer, HIV/AIDS, and Alzheimer's disease. With continued innovation and collaboration, pharmaceutical engineering will continue to make important contributions to the field of medicine.。

药物合成知识提供了宝贵的刺激研发化学家以及。
有没有首选的所有药学活性化合物,也反应类型结构类型的首选。
这意味着几乎全部领域的有机和有机金属化学中的一部分也被覆盖。
不过,也有较大的起始原料和中间体数量较常用,所以它是非常有用的知道他们准备从初级品的可能性。
基于这个原因,它是在适当的地方,说明这本书的重要中间体,尤其是树。
后面这些中间体领导到数目庞大的代理商合成工艺中的关键化合物。
对于大多数的化学品是在涉及大量生产。
以类似的方式,这也是对工业芳香族化合物甲苯,苯酚和氯苯中间体为基础的真实。
另一个关键的化合物可能会显示在表格可在追踪syntheses.f交叉关系很有用除了实际的起始原料和中间体溶剂作为反应介质要求和通过再结晶纯化,两者。
常用的溶剂是甲醇,乙醇,异丙醇,丁醇,丙酮,醋酸乙酯,苯,甲苯和二甲苯。
在较小程度上乙醚,四氢呋喃,乙二醇醚,二甲基甲酰胺(DMF)和二甲基亚砜(DMSO)的使用在特殊的反应。
在较大的数额使用的试剂,不仅酸(盐酸,硫酸,硝酸,醋酸),而且无机和有机碱(氢氧化钠,氢氧化钾,碳酸钾,碳酸氢钠,氨,三乙胺,吡啶)。
进一步的辅助化学品包括活性炭和催化剂。
这些(如中间体)补充品都可以成为最终产品中杂质的来源。
1969年,世界卫生组织发表了`保障药品质量的论文中(WHO技术报告号418,1969,附录二,附录二是有关`适当的做法的赔偿和保障药品质量。
';号567,1975,附件1A)。
这已成为在此期间为'良好生产规范'或GMP规则众所周知的,现在应在这些药品生产服从。
它们构成的质量有关的药品生产证书互认的生产和检验的基础。
设施。
长期以来,美国药品管理局,美国食品和药物管理局(FDA)已发出的药品制剂类似于谁的规则规定,而且适用于这些严格。
向美国药物如成品者外,出口由FDA要求的生产设施进行定期检查。
5它可能只是在此指出,这种严格控制不仅适用于产品,而且对原材料(原辅料控制),同时还以中间体。
清楚。
对生产和储存方面的技术和设备必须符合卫生规定的条件。
由于只有少数的化合物,如乙酰水杨酸,对乙酰氨基酚和维生素,是在大量的准备,在实际生产中最需要的多用途(多产品)设施的地方。
特别小心,注意避免交叉通过什么可以按所使用的仪器良好的清洁影响其他产品的污染。
经过仔细的描述和所有储存的中间体和产品的定义是必要的。

5、药物研发(I)1、简介药品开发是一个非常复杂的过程,需要一个协调和沟通不同功能之间的群体广泛很大。
它是昂贵的,特别是在临床开发的后期阶段,在研究涉及的数百名病人。
据估计,目前约2.3亿美元(1987美元)的新药开发成本,并采取介于7和10多年的临床前开发阶段开始,首先市场(不包括监管滞后)。
药物开发是一项高风险业务,虽然利率不断上升,大约只有每十个新的化学研究在人类首次实体开展会不会成为一个产品。
作为候选药物的进步,通过发展'的失败降低风险hurdles'are克服前进的道路上。
失败的典型原因包括不可接受的毒性,缺乏有效性,或不能提供比其他竞争产品的优点(图1)损耗率的新化学实体(竞争性考试的)进入发展。
