These variables may include the particle size distribution (including aggregates or lumps of material), particle shape (spheres, rods, cubes, plates, and irregular), presence of moisture (or other volatile compounds), particle surface properties (roughness, cohesion), and powder flow properties. After a couple of bad experiences, we now walk away from prospective clients who are penny wise and pound foolish. During this, the reagent A that is added is exposed to a much higher stoichiometric amount of reagent B until it is all added, and this imbalance can lead to reagent A prematurely reacting, and subsequent products to also react with the huge excess of reagent B. Those detailed steps include dates and times for starting and completing each significant step, including weighing of all raw materials and intermediates; identification (initials) of the operator(s) who performed each step and the name of the person who checked and verified these operations. For powder-based continuous processes, it is critical to feed powders consistently and accurately into subsequent unit operations of the process line, as feeding is typically the first unit operation. Jumping right to production before validating the processes opens us to having to fix something that should have been addressed earlier – when it would have been easier, faster and less costly. portalId: '690896', Free PDF. [1], Whether to add organic solvent into aqueous solvent, or vice versa, becomes important on the industrial scale. checks on materials, pre- treatments, sequence for adding materials, critical process parameters (time, temp etc.) The MBR also includes any in-process controls (with their limits) and records the actual results (when executed) as well as any sampling with test results recorded; all packaging materials, labeling and storage conditions are defined and listed; the expected yield of relevant intermediates and the final product; and the actual product yield obtained; and any deviation from the instructions is noted and recorded. Finally, master batch records must be well written, with clear, concise and accurate language that conveys the technical and procedural information necessary to ensure consistent manufacturing of drug substance that meets all safety, efficacy and quality requirements. Continuous pharmaceutical manufacturing offers potential flexibility, quality, and economic advantages over batch processing, both in process development and manufacturing for the pharmaceutical sector.

To formulate tablets that are bioavailable according to indication requirements. 3. Drug manufacturing is the process of industrial-scale synthesis of pharmaceutical drugs as part of the pharmaceutical industry. Current Good Manufacturing Processes (cGMP) require that not only incoming raw materials but all in-process materials be tested for identity, strength, quality, and purity throughout the manufacturing process. The MBR lists all the equipment that is to be used with safeguards to ensure the equipment is suitable for use. Finally, lower temperatures can result in crusting of reagents, intermediates, and byproducts to the reaction vessel over time, which will impact the purity of the product. The primary processing stage focuses primarily on the development of active ingredients of the drug. The MBR is part of the required documentation for compliance with Good manufacturing practices in order to conform to the ICH “Guidance for Industry, Q7 Good Manufacturing Practice Guidance for Active Pharmaceutical Ingredients” as well as EudraLex – Volume 4 Good manufacturing practice (GMP) Guidelines for the European Union. Managing data as paper-based process is not only longwinded, but is prone to errors. [2] Feeders have been designed to achieve performance reliability, feed rate accuracy, and minimal disturbances. [1], In continuous manufacturing, input raw materials and energy are fed into the system at a constant rate, and at the same time, a constant extraction of output products is achieved. A short summary of this paper. This can only be done with the input of Research & Development, Safety & Environmental, Manufacturing, Engineering, Quality Control and Quality Assurance.

To formulate tablets that are chemically and physically stable over a long period of time. We would much rather use the time allotted efficiently, and move on to the next project. In recent years, there has been discussion of value manufacturing technology innovations (batch vs. continuous manufacture, PAT, QBA, QBD) for active pharmaceutical ingredients (API) and formulations. The cost to cool a typical reactor to this temperature is large, and the viscosity of the reagents typically also increases as the temperature lowers, leading to difficult mixing. The manufacturing steps contain the design conception, withdrawal, dispensation, manufacture, alteration, liberation, packaging and storage. Download PDF Package. If you cut corners or have a sloppy MBR, you will wind up with other, bigger problems. 3.5. This is an opportunity for the sponsor’s team and the CMO team to get comfortable working together. Because they had a tight budget, they asked us to just put it into GMP production with very minimal assessment. And the delays often have a cascading effect on other aspects of development. Production and Process Controls: Overview of CGMP Regulations and Regulatory Expectations Presenters: Vibhakar Shah, Ph.D., Consumer Safety Officer Office of Policy for Pharmaceutical … According to a report by Zenith Technologies, data scientists spend around 60 to 80 per cent of their time analyzing data before they gain any insights. When adding organic solvent to aqueous, stoichiometry must be considered again as the excess of water could hydrolyze organic compounds in only mildly acid base conditions. Download Full PDF Package. GMP guidelines were developed for good reason and ensure that sound and efficient processes are followed for the success of a pharmaceutical project, as well as to ensure its efficacy and safety. Handbook of Pharmaceutical Manufacturing Formulations: Over-the-Counter Products ... the process of ob-taining the information may be cumbersome, ... 12. Without solid, analytical methods, you can’t determine if what you have is good or bad – but sometimes people try to cut back on analytics. If you feel like you can’t trust your outsourcing partner, you should identify concrete examples of why you don’t trust them. 37.6 Conclusion. While a laboratory may use dry ice as a cooling agent for reaction selectivity, this process gets complicated on an industrial scale. Pharmaceuticals made using continuous manufacturing are moved nonstop within a single facility, eliminating hold times between steps. While biotech in general is doing well, there’s always pressure on biotechs to use their funds more efficiently and productively. By law, pharmaceutical manufacturers must identify and verify all incoming materials. Therefore, one of the main challenges for the control of a continuous pharmaceutical manufacturing plant resides in obtaining a continuous stream from raw materials to product while being able to respond to process disturbances, which is left for further research. Ashley John, New Jersey Institute of Technology, Newark, New Jersey, Analytical and Computational Methods and Examples for Designing and Controlling Total Quality Management Pharmaceutical Manufacturing Systems. This can take three days, yet we’ve heard some other CMOs can spend two weeks to clean and validate fixed equipment. PDF. [3][4], In the pharmaceutical industry, a wide range of excipients may be blended together with the active pharmaceutical ingredient to create the final blend used to manufacture the solid dosage form. They tend to cut corners that are counterproductive and result in additional costs and delays – the opposite of what they had intended. “Process Systems Engineering for Pharmaceutical Manufacturing” is an ambitious reference comprising 24 chapters covering process systems engineering (PSE) methods and case studies of interest to engineers working in pharmaceutical process development, model development, process simulation, process optimisation and supply-chain or enterprise optimisation. When it turned out that their material didn’t meet regulatory standards, our Quality Assurance (QA) team would not release the material — which is the right decision — and we had to go back and do additional work just to get the material ready to be released. Expanded details on critical steps in the manufacturing processes provided but to keep the size of the book man- Org. In an even wider scope, the location of your chemical plant can play a role in the ambient temperature of your reaction vessel. The main different between small-scale and large-scale GMP manufacturing is the equipment used. [7], Hot melt extrusion is utilized in pharmaceutical solid oral dose processing to enable delivery of drugs with poor solubility and bioavailability. Rahul Goud. Our scientists typically work on more projects in one year than many sponsors work on in several years. Sponsors who don’t like to take advice and counsel often end up costing themselves more by trying to cut the wrong corners or pursuing the wrong solutions. We’ve seen some projects that, during the scaling-up period, find impurities that were not present in smaller quantities. The process of bringing a new product to market can seem long and daunting, and might be enough to put you off getting started. The process involves the application of heat, pressure and agitation to mix materials together and 'extrude' them through a die. that are needed for the manufacture of the intermediate or API. It’s cheaper in the long run. Before and during GMP manufacturing is never the time to cut corners to save costs, because that strategy often comes with a heavy price. Pharmaceutical Industry Nani Masters. That took an additional six weeks, and resulted in a lower yield – at a cost of more than $200,000. The pharmaceutical manufacturing unit follows a series of steps to produce effective medicines. It's an exciting field! Deadline pressure can cause people to miss steps or cut corners. Process … PDF. To formulate tablets that are uniform in weight and in drug content. If the problem is intractable or if the outsourcer is unwilling to make changes then it might be time to make a change. The process performance is heavily dependent on stability of the material flowrate. Material is fed through an assembly line of fully integrated technologies, which saves time and reduces the likelihood of human error. READ PAPER. On the industrial scale, adding a large amount of reagent A to reagent B may take time. There are a number of reasons for this, including increasing homogeneity and dosage uniformity, increasing bioavailability, and increasing the solubility of the drug compound. To formulate tablets that are strong and hard to withstand mechanical shock encountered during manufacturing, packing, shipping, dispensing and use. On the other hand, the worst projects usually stem from a lack of trust: from sponsors who don’t trust their outsourcing partner, and from our team not trusting the sponsor to make the right decisions. 4. During the drug manufacturing process, milling is often required in order to reduce the average particle size in a drug powder. 2. A lack of trust makes a complex project even more challenging. In addition to the engineer, our QA team validates the raw materials, specifications, and purification levels as well as the step-by- step approach to the manufacturing to ensure consistency across different batches before it can go into the GMP manufacturing lab. There are a number of challenges that the industry faces in order to transition towards more competitive, systematic and efficient manufacturing. Unit Opera- tions are determined by what manufacturing steps are needed to combine the active ingredient with other needed ingredients to make a quality finished product. Milling, granulation, coating, and tablet pressing are all potential parts of the process.

For example, a client once came to us with a substance that had been developed in another lab. PDF. There’s a lot of pressure for companies with limited funding, especially those run by business people, to try to save money at every step of the way – perhaps by going with the cheapest bid or skimping on some prep work or analytics. The present invention provides for methods of manufacturing a pharmaceutical composition comprising selecting one or more than one starting material to make a liquid active pharmaceutical ingredient; and using the liquid active pharmaceutical ingredient to make a pharmaceutical composition. The Costs of GMP: Cutting the Wrong Corners, Mistakes & Sloppy Master Batch Records Page 3 of 3. Granulation prevents the "demixing" of components in the mixture, by creating a granule which contains all of the components in their required proportions, improves flow characteristics of powders (because small particles do not flow well), and improves compaction properties for tablet formation. These two units are primary processing stage and the secondary processing step. The Evolving State of Continuous Processing in Pharmaceutical API Manufacturing: A Survey of Pharmaceutical Companies and Contract Manufacturing Organizations. An essential component for modern pharmaceutical manufacturing is clean, relevant and accurate data.
