STEP 2: Overview of Good Manufacturing Practice (10 minutes) • The first World health organization (WHO) drafts text on good manufacturing practices (GMP) was prepared in 1967 by a group of consultants at the request of the Twentieth World Health Assembly. • In 1969, when the World Health Assembly recommended the first version of the WHO Certification Scheme on the Quality of Pharmaceutical Products Moving in International Commerce, it accepted at the same time the GMP text as an integral part of the Scheme. • The guide to GMP shall be used as a standard to justify GMP status, which constitutes one of the elements of the WHO Certification Scheme on the Quality of Pharmaceutical Products Moving in International Commerce, through the assessment of applications for manufacturing authorizations and as a basis for the inspection of manufacturing facilities. • It may also be used as training material for government drug inspectors, as well as for production, quality control and quality assurance personnel in the industry. STEP 3: Definition of Good Manufacturing Practices (5 minutes) • Good Manufacturing Practices o Good Manufacturing Practice is that part of Quality Assurance which ensures that pharmaceutical products are consistently produced and controlled to the quality standards appropriate to their intended use and as required by the marketing authorization or product specification. QUALITY ASSURANCE Good Manufacturing Practices QUALITY CONTROL (GMP) 2 PST 05207 Quality Assurance of Pharmaceutical Products NTA Level 5 Semester 2 STEP 4: Principles of GMP (30 minutes) Activity: Brainstorming (5 minutes) ASK students to brainstorm on the following question • What are the principles of GMP?

The basic principles /essential elements are: o Quality assurance o Good manufacturing practices for pharmaceutical products o Sanitation and hygiene o Qualification and validation o Complaints o Product recalls o Contract production and analysis o Self-inspection and quality audits o Personnel o Training o Personal hygiene o Premises o Equipment o Materials o Documentation o Good practices in production o Good practices in quality control 3 PST 05207 Quality Assurance of Pharmaceutical Products NTA Level 5 Semester 2 STEP 5: Importance of GMP in pharmaceutical manufacturing (60minutes) Activity: Buzzing (10 minutes) ASK students to pair up and buzz on the following question for 2 minutes •What are the importances of GMP in pharmaceutical manufacturing? ALLOW few pairs to respond and let other pairs to add on points not mentioned WRITE their response on the flip chart/board CLARIFY and SUMMARIZE by using the content below • Manufacture of pharmaceutical products involve operations of purchase of materials, production, quality control, release, storage, shipment of finished products and the related controls. Such operations need to be carried out according to Good Manufacturing Practices (GMP) that forms an important part of a comprehensive system of quality assurance. Adherence to GMP ensures that pharmaceutical products are manufactured to meet quality standards required for their intended use. • Good manufacturing practice is that part of quality assurance which ensures that products are consistently produced and controlled to the quality standards appropriate to their intended use and as required by the marketing authorization. • GMP is aimed primarily at diminishing the risks inherent in any pharmaceutical production. • Such risks are essentially of two types: cross-contamination (in particular of unexpected contaminants) and mix-ups (confusion) caused by, for example, false labels being put on containers. It is required that: o All manufacturing processes are clearly defined, systematically reviewed in the light of experience, and shown to be capable of consistently manufacturing pharmaceutical products of the required quality that comply with their specifications; o Qualification and validation are performed. o All necessary resources are provided, including ,  Appropriately qualified and trained personnel.  Adequate premises and space.  Suitable equipment and services.  Appropriate materials, containers and labels  Approved procedures and instructions.  Suitable storage and transport.  Adequate personnel, laboratories and equipment for in- process o Instructions and procedures are written in clear and unambiguous language specifically applicable to the facilities provided. 4 PST 05207 Quality Assurance of Pharmaceutical Products NTA Level 5 Semester 2 o Operators are trained to carry out procedures correctly. o Records covering manufacture and distribution, which enable the complete history of a batch to be traced, are retained in a comprehensible and accessible form. o The proper storage and distribution of the products minimizes any risk to their quality. o A system

STEP 2: Overview of GMP Components (5 minutes) • Good manufacturing practice (GMP) is a vital component of quality assurance which helps to ensure that pharmaceutical products are consistently produced with the quality standards appropriate for their intended use • GMP defines quality measures for both production and quality control and defines general measures to ensure that processes necessary for production and testing are clearly defined , validated reviewed and documented and that the personnel, premises and material are suitable for the production of pharmaceuticals and biological including vaccines. STEP 3: Components of GMP (20 minutes) The following are components of GMP: • Premises of good design, which are regularly monitored. • Equipment of appropriate design and which are well maintained. • Personnel who are well trained and motivated. • Quality control of raw materials. • Quality control of finished products • Written procedures & other documentation • Packaging and labelling control. STEP 4: General Premise Requirements (80 minutes) Activity: Brainstorming (5minutes) ASK students to brainstorm on the following question for 5 minutes • What is a premise as in regards to GMP? ALLOW students to brain storm for 5minutes WRITE their response on the flip chart/board CLARIFY and SUMMARIZE by using the content below 8 PST 05207 Quality Assurance of Pharmaceutical Products NTA Level 5 Semester 2 • By definition Premises include land, buildings, structures, basements and vessels and in relation to any building includes a part of a building and any cartilage, forecourt, yard, or place of storage used in connection with building or part of that building; and in relation to ''vessel'', means ship, boat, air craft, and includes a carriage or receptacle of any kind, whether open or closed. (TFDC Act 2003). • Premises requirements: o The land and buildings where the manufacturing operations are located must contribute towards the quality of the products. They do this by avoiding the risks of contamination, permitting effective cleaning and maintenance, minimizing the build- up of dirt and dust and preventing quality defects. . o The geography of the chosen location can have a considerable impact upon the design of facilities. Is the location subject to earthquake hazards? Does it experience flooding regularly – during the monsoon season? What precautions need to be taken regarding continuity of supply of services? o The climate of the area is also important. If the company will be handling, for example, gelatine capsules then humidity are of great concern. If the company has a lot of goods requiring temperature or humidity controls in transport, and the goods have to sit on the dockside for weeks waiting for a boat to arrive, there may be a problem with the quality of the products. The company may need to rent temperature-controlled storage. If it does, how will it check the quality of that storage? • The factory may have to seek some expensive design solutions to overcome the problems that arise. Does the process make a lot of noise, for example? If it does and the location is close to neighbours, then the company may be forced into expensive soundproofing. • The neighbourhood is also important. If the company is to be located next to a steel mill then the design precautions that it will have to take, and the level of maintenance that it will have to undertake, will be very different than if it is in a rural setting. If the neighbours change, the company will need to take appropriate measures to handle the situation correctly. • The company is also required to take measures that prevent the factory polluting the surrounding area with product or by-products from its manufacturing processes. • A site inspection is useful before building commences to ensure that the area is suitable for the construction of a pharmaceutical factory • How do we achieve good conditions in the factory? o The layout and design of premises must aim to minimize the risk of errors and permit effective cleaning and maintenance in order to avoid cross-contamination, build-up of dust or dirt, and, in general, any adverse effect on the quality of products. o Premises should be carefully maintained, and it should be ensured that repair and maintenance operations do not present any hazard to the quality of products. o Electrical supply, lighting, temperature, humidity and ventilation should be appropriate and such that they do not adversely affect, directly or indirectly, either the pharmaceutical products during their manufacture and storage, or the accurate functioning of equipment. 9 PST 05207 Quality Assurance of Pharmaceutical Products NTA Level 5 Semester 2 o Premises should be designed to ensure the logical flow of materials and personnel corresponding to the sequence of the operations and to the requisite cleanliness levels. o Interior

STEP 2: General Possible Issues Related to Personnel in GMP ( 35 minutes) Activity: Buzzing (5 minutes) ASK students to pair up and buzz on the following question for 2 minutes • What are general possible issues related to personnel in GMP? ALLOW few pairs to respond and let other pairs to add on points not mentioned WRITE their response on the flip chart/board CLARIFY and SUMMARIZE by using the content below • The general possible issues related to personnel in GMP are: o In a company the issues will be around a lack of skills and resources to comply with all the requirements of GMP:  Limited staff numbers may mean that people are under pressure to perform. They may be trying to do too much. There may be a lack of deputies during times of illness or holidays.  Recruited staff may have inadequate qualifications.  Recruited staff may have inadequate experience or experience in an inappropriate area. Sometimes the owner recruits relatives who are inadequately qualified or experienced.  The owner may interfere with quality decisions, particularly if orders are required urgently or are very valuable. Senior staff may have difficulty in combating this, since it may cost them their jobs.  Smaller companies may have no means to develop training materials to educate their staff in the requirements of GMP. They do not become members of the local manufacturers‟ association because of cost. They do not then have access to training programmes that are available through the association.  Subsidiaries of multinational companies may claim that company procedures or standards take precedence over local legislation. If this is claimed, it will be most unusual since all multinationals require local companies to conform first to local legislation. It will be worth exploring with the company what benefits are obtained by not conforming to local legislation.  Large organizations often move people around through promotion, training, recruitment or relocation. In so doing they can lose sight of the requirements of GMP. Managers can be promoted into positions for which they are not qualified or experienced. 14 PST 05207 Quality Assurance of Pharmaceutical Products NTA Level 5 Semester 2  Companies may not keep adequate training records even though people are apparently undergoing training.  As with small companies, large companies may have personnel policies that penalize people. The problem is that if people are not going to be paid when sick or injured, they may work on under circumstances that create a risk to the product. STEP 3: General Principles Related to Personnel in GMP ( 30 minutes) The following are principles related to personnel in GMP: • For successful and good quality pharmaceutical production, it is essential to have people with sufficient knowledge and experience to undertake the work. They must have the authority and the means to do that work, and there must be enough of them available to carry out tasks effectively. • It is most important that the people that are recruited are selected from a group that can meet the requirements. • It is not recommended to recruit people to work in manufacturing areas if they are unable to read the instructions for their safety and for product quality. A medical examination should be included during the recruitment processes. Operators working with cytotoxic products may need blood tests at the time of recruitment and at six monthly intervals thereafter. • Operators who will work on visual inspection processes should also undertake an eye test at the time of recruitment with a regular check on a periodic basis afterwards. • A major and most common problem is that of insufficient people available to do the work. It is of little value having just one person well qualified and experienced, with no backup staff. What then happens in the case of sickness or holiday? This can be a very difficult area, and one which is harder for smaller companies than a multinational company or similar. • Another issue that often surfaces is the employment of a well-qualified, but inexperienced person to manage, for example, quality. An illustration of this is the recruitment by the owner of a small company of a relative — who is newly qualified, but completely inexperienced to run a laboratory or manufacturing area. • The duties incumbent upon any one individual should not be so extensive that he/she cannot cope, resulting in a risk to quality of the product. • Staff must have a clear job description which tells them

STEP 2: Definition of Pharmaceutical Raw Materials (15 minutes). Pharmaceutical raw materials generally are substrates or elements which are used for manufacturing different types of drugs, and basically categorized into three major types which are: Raw Material of API: Any substance or mixture of substances intended to be used in the manufacture of a pharmaceutical dosage form and that, when so used, becomes an active ingredient of that pharmaceutical dosage form. Such substances are intended to furnish pharmacological activity or other direct effect in the diagnosis, cure, mitigation, treatment, or prevention of disease or to affect the structure and function of the body. Main thing is that Accuracy and Precision are must for the raw materials which is used for making the API. Raw Material of Expedients: is a substance formulated alongside the active ingredient of a medication, included for the purpose of long-term stabilization, bulking up solid formulations that contain potent active ingredients in small amounts (thus often referred to as "bulking agents", "fillers", or "diluents"), or to confer a therapeutic enhancement on the active ingredient in the final dosage form, such as facilitating drug absorption, reducing viscosity, or enhancing solubility. Excipients can also be useful in the manufacturing process, to aid in the handling of the active substance concerned such as by facilitating powder flowability or non- stick properties, in addition to aiding in vitro stability such as prevention of denaturation or aggregation over the expected shelf life. The selection of appropriate excipients also depends upon the route of administration and the dosage form, as well as the active ingredient and other factors Raw Material of Packaging: Raw material which is used in making most of the packaging involve plastic & polymers, glass, paper, aluminum foil and paper boards 21 PST 05207 Quality Assurance of Pharmaceutical Products NTA Level 5 Semester 2 STEP3:Types of Raw Materials Used in Pharmaceutical Manufacturing (50 minutes) Activity: Small Group Discussion ( 10 minutes) DIVIDE students into manageable groups ASK students to discuss in groups on the following questions • What are major types of raw materials used in pharmaceutical manufacturing? ALLOW students to discuss for 5 minutes ALLOW groups to present for 5 minutes CLARIFY and SUMMARIZE by using the contents below The major types of raw materials used in pharmaceutical manufacturing are • Active pharmaceutical ingredient-(API), • excipients and • Packaging materials as shown in step two of this lecture. The following are some of pharmaceutical excipients commonly used in pharmaceutical manufacturing of solid dosage forms. TABLE ONE (1) EXCIPIENTS used in solid dosage forms.

STEP 2: Definition of Documentation Terms (15minutes) Batch (or lot): A defined quantity of starting material, packaging material, or product processed in a single process or series of processes so that it is expected to be homogeneous. It may sometimes be necessary to divide a batch into a number of sub-batches, which are later brought together to form a final homogeneous batch. In the case of terminal sterilization, the batch size is determined by the capacity of the autoclave. In continuous manufacture, the batch must correspond to a defined fraction of the production, characterized by its intended homogeneity. The batch size can be defined either as a fixed quantity or as the amount produced in a fixed time interval. “Manufacturing” includes all operations of receipt of materials, production, packaging, repackaging, labelling, relabeling, quality control, release, storage and distribution of APIs and the related controls Master Formula: A document or set of documents specifying the starting materials with their quantities and the packaging materials, together with a description of the procedures and precautions required to produce a specified quantity of a finished product as well as the processing instructions, including the in-process controls. Master Record: A document or set of documents that serve as a basis for the batch documentation (blank batch record). ALCOA+ A commonly used acronym for „Attributable, Legible, Contemporaneous, Original and Accurate‟ which puts additional emphasis on the attributes being „Complete, Consistent, Enduring and Available‟– qualities which are implicit in the basic ALCOA principles. Backup: A backup means a copy of one or more electronic files created as an alternative in case the original data or system are lost or become unusable. Computerized System: A computerized system can create, modify, maintain, archive, retrieve or transmit electronic records. A computerized system consists of hardware, software and network components which together fulfill certain functionalities. They can also be defined as a logical entity, partially or entirely controlled by computer but may also include some equipment, utilities, sensors and actuators along with the governing procedures. Examples of such a system are Building Management System (BMS), Automated Manufacturing/Laboratory System, Document Management System, 32 PST 05207 Quality Assurance of Pharmaceutical Products NTA Level 5 Semester 2 Criterion Meaning Attributable Attributable‟ means information is captured in the record such that it is uniquely identified as executed by the originator of the data (e.g., a person and/or a computer system). Legible The terms „legible‟, „traceable‟ and „permanent‟ refer to the requirements that data are readable, understandable and allow a clear picture of the sequencing of steps or events in the record Contemporaneous is the process of documentation (on paper or electronically) at the time of the occurrence of an activity Original Original‟ data includes the first capture or capture at source of data or information and all subsequent data required to fully reconstruct the conduct of the GxP activity Accurate Accurate‟ means that data are correct, truthful, valid and reliable. complete „Complete‟ means that all data from analysis, including any data generated before a problem is observed, data generated after repeating part or all of the work, or re-analysis performed on the sample are contained in the data record Consistent „ means that all elements of the analysis, such as the sequence of events, follow on and data files are date-stamped (all processes) and time stamped (when using a hybrid or electronic system) in the expected order and such data are contained in the record. Enduring Enduring‟ means that all data have been recorded on authorized media which can be preserved for a period of time, e.g., laboratory notebooks, numbered worksheets, for which there is accountability, or electronic media. Data recorded on scrap paper or any other media which can be discarded later, e.g., backs of envelopes, laboratory coat sleeves or Post‑It notes, etc. are not considered enduring. Available Available‟ means that the complete collection of records can be accessed or retrieved for review and audit or inspection over the lifetime of the record 33 PST 05207 Quality Assurance of Pharmaceutical Products NTA Level 5 Semester 2 STEP 3: Good Documentation Practices (GDocP) (25 minutes) Activity: Buzzing (5minutes) ASK students to pair up and buzz on the following questions for 5 minutes • What is a good documentation practice?
