Since 1959, Thomas Engineering has dedicated itself to excellence in the design and manufacturing of pharmaceutical tablets. Other methods include fluidized bed coating, dry coating, but the most widely used method in the pharmaceutical and nutraceutical industry today is that of film coating. Process parameters to observe during when setting up coating machines and during the coating process: How to Make Your Own Tablets - Free eBook. India. The coating of OSD in pharmaceuticals has been practised since time immemorial. • Excessive pan speed in coating process - Reduce pan speed • Spray rate too low - Increase spray rate ... Ankur Choudhary is India's first professional pharmaceutical blogger, author and founder of Pharmaceutical Guidelines, a widely-read pharmaceutical blog since 2008. Current Good Manufacturing Practice (cGMP) and the demands of the regulatory authorities worldwide require utmost care not only in the equipment used in the preparation of tablets to be coated and the coating operation but also in the design of manufacturing facilities, the selection of materials used in their construction, their layout. enhances mechanical properties (abrasion & compressibility), improves aesthetic appeal (Texture, appearance, odour and taste), and. Oral Solid Dosages constitute a significant portion of medicine manufacturing due to patient’s adherence to recommended treatments, efficiencies in drug manufacturing and high-precision dosage. Ideally, the spray pattern must meet the tablet surface and cover almost the entire tablet bed. With the 4-port gun, three ports are for air and one for liquid, and these allow for the independent control of activation pressure, atomization pressure and spray width. There are three common atomizer gun types – 2-port, 3-port and 4-port. Sun Coating Company provides many different coating processes to the pharmaceutical industry. © 2020 LFA Machines Oxford LTD. All Rights Reserved. The guns should be adjusted if there is a variation of more than 10% in spray rate between each of the guns. If the guns are too close, the spray width would be narrow resulting to non-uniform coating. Spray guns within the drum are then activated to create a fine mist of coating solution that dries as soon as it reaches the surface of the tablets. To get the required spray width, it is important to optimize the gun-to-gun distance and the gun-to-bed distance. The coating process begins with the preparation of a suspension that consists of the coating formulation (primarily solid ingredients) and a liquid solvent which is water, alcohol or an organic solvent. Film-coating technology has gone through various modifications to meet the demand of the pharma industry. Automatic coaters are used for all kinds of coatings; they can be equipped with a remote control panel, a dehumidifier, and dust collectors. Nowadays, pharmaceutical film coating represents a significant process step in the pharmaceutical industry. of solvent-free coating in the pharmaceutical industry [11]. PHARMACEUTICAL MANUFACTURING 2. The automated controlled process parameters. Bohle design for … The drug release profile can be modified and or controlled. Also, required is an air handling unit and dust collector, and the associated controls. These are heated in a stream of flowing air and time allowed for dust to settle and a steady temperature of the outlet air to be reached (typically 40 to 46°C). Sugar Coating is largely borrowed from the confectionery industry which had developed this technique and is still widely used today. The coating application is through a physical deposition process, i.e. The use of pharma grade pigments or shining materials to the coating ingredients can increase the elegance or aesthetic value of the drug. Our equipment includes Auto Coater, Fluid Bed Processor and Fluid Bed Coater that is designed to meet all the critical process parameters and achieve the end product quality parameters. Several spray guns may be located in the coating drum and each one of them must be set up properly. However, high negative pressures must be avoided to ensure that some spray is not lost via the air exhaust port. tablets, capsules and syrups in modern times. In essence, this blog on Pharmaceutical Coating discusses the need and the process carried out for coating. This layer is in the range of 20 to 200 μm in thickness, or around 1 to 9% of the initial weight of the tablet. In 2011, L.B. Tablet coating is a common pharmaceutical technique of applying a thin polymer-based film to a tablet or a granule containing active pharmaceutical ingredients (APIs). A wide variety of pharmaceutical products, including pellets, granules, capsules, powders, and crystals are often coated. High Efficiency Tablet Film Coating Machine In Pharmaceutical Industry . These granules or core tablets are coated using soluble cellulose materials. The main reasons why tablet coating is used in the pharmaceutical industry are; Masking: the color, odor or taste of the tablet; Contamination: Reduces cross contamination; Easy swallowing: encapsulating the tablet with a smooth surface; Protecting: to enhance the expiration date; Release of the drug: The control the release of the drug in the human body Coating Technology S.r.l. Film-coating formulations usually contain the following components: Particle/ Granule or pellet coating is a thin layer of a substance that is placed around a core particle, granules or pellets. The selection of instruments to measure the appropriate parameters; how the coating process may be optimized and the process scaled-up to control the coating of production size batches successfully. Do you recollect having a medication prescribed by your doctor that tastes sweet at first and later on leaves a bitter taste in the mouth or a lump in the throat for a couple of minutes after gulping it down? film coating resulting from the spraying and subsequent drying of solutions or dispersions. Also, it was not until the mid-twentieth century that colours became an essential addition to the coating in the pharma industry. To avoid issues caused by non optimal loading of the coating pan, manufacturers often use a multi-pan approach where different drum sizes are used to accommodate different batch sizes. Film coating has evolved with time, keeping pace with demands of the pharma industry. Medications have transformed from “only” medicinal ingredients during ancient Egpyt to acquiring various shapes, sizes, i.e. 3. By checking the first 3 to 5 batches in this way, the rotation speed of the peristaltic pump can be verified. For the best experience on our site, be sure to turn on Javascript in your browser. This alteration allowed for more solution or film coating to evaporate in less time. The coating itself can serve several functions – it can strengthen the tablet, control the release of active ingredients, improve its taste, provide colour, make it easier to package and handle, and protect it from moisture. Disruption of spray rate, for example, will often produce defective tablets. It also allows embossing or printing on the tablet. This type of pump allows for accurate control of rate which depends only on the tubing size used in the pump and the speed of rotation of the pump. Management of Coating Processes is affected through an ascending range of Automation and Controls. Balancing both spray rates and drying conditions to achieve good coating process efficiency (typically > 90% and ideally > 95%). In recent years, a novel low molecular weight hypromellose (hypromellose 2906, VLV hypromellose) was developed to improve tablet-coating process and lower costs in the pharmaceutical industry.

Coating is a process by which an essentially dry, outer layer of coating material is applied to the surface of a dosage form in order to confer specific benefits that broadly ranges from facilitating product identification to modifying drug release from the dosage form. Current pharmaceutical coating processes use coating pans, of a broad range of designs, made from stainless steel, where drying of the product being coated is achieved by means of a supply of heated air, and moisture and dust-laden air is removed from the vicinity of … Drum loading—when tablets are first loaded, check broken, capped or chipped tablets. Most coating processes take place for drug stability improvement, drug release modification and taste masking. This article describes the essential process steps and equipment required for film coating tablets. The technologies include Microencapsulation, top spray and bottom spray (tangential or Wurster coating). Tablet Flowing Issues Troubleshooting Guide. The spray rate can be monitored by checking the usage of coating solution (e.g., following the weight change of a reservoir with time). The spray rate or supply rate of coating solution is usually controlled using peristaltic pumps. Risk of interaction between two incompatible substances. Gun nozzles – must be kept clean and free of product build-up. With a 3-port system, the atomization and spray activation pressures can be controlled independently which allows the spray width to be controlled. Most often these are atomizers that use compressed air to atomize the coating solution or suspension. It is important therefore to keep a check on the pressure within the drum during a coating operation. Compression coating is similar to the tablet technology, where the core or coated tablets are surrounded by compressible excipients, which prevents the drug incompatibilities and protects the drug from environmental factors like light, humidity and oxidation. Increasing the amount of coating applied to allow better and more consistent tablet coverage. Though the stages differ from one manufacturer to another, a typical sugar-coating process involves the following steps: Sealing; Subcoating; Smoothing (or Grossing) Colouring/ Colour coating; Polishing (or Glossing) Printing; Sugar coats are often shiny and highly coloured. The pharmaceutical coating can be applied to a wide range of Solid Oral Dosage forms including tablets, granules, crystals, powdersor pellets. The results of this analysis revealed that, when it comes to tablet coating in pharmaceutical industry, the option of pollution preventing by modifying the design of the process represents a general approach that provides huge benefits both in terms of cost-effectiveness and waste/environmental impact minimization. Our experts are on hand to offer you advice on the different pharmaceutical coating processes and deliver the best solution for your specific coating application. Sugar coating was one of the earliest methods developed to coat tablets and is still practised for some products, especially confectionery. Although this pharmaceutical process has been around for almost a century yet, it continues to be a crucial aspect of the modern medicine making process with advanced machinery and technologies. Spray Rate – Film Coating Process Monitoring the spray delivery rate, is crucial especially in aqueous film coating as variations in the spray rate during the coating process can lead to several problems, such as picking and sticking, orange peeling and frosting.and erosion, all of which are caused by over-wetting of the tablets. For the best experience on our site, be sure to turn on Javascript in your browser. Reducing coating solids to facilitate more even coating distribution. The process of sugar-coating involves. The following are the process parameters to be monitored, validated and set for a product to get quality products with maximum yield. Do defects occur when the drum is first loaded or when rotated? Bohle introduced KOCO ®, the first semi-continuous coater for the pharmaceutical industry, to the market.The KOCO ® is designed as a semi-continuous coater and stands out for its high throughput. Developed continuously in the last decades, coating technology originally derived from dragée pan processing. The time taken to achieve this can range from a few minutes to several hours and is governed by the particular characteristics of the coating material, as well as the process parameters such as drum speed, temperature, pressure and spray rate. The coating process involves an iterative application of sucrose based solution to the tablet within the coating pan. However, this coating technique is not as popular in the pharmaceutical industry as it was once, due to the laborious procedure and long process time, a requirement of skilled and trained personnel, and the inability to emboss, print or label the tablet and increases the size and weight of the tablet. The pharmaceutical coating can be applied to a wide range of Solid Oral Dosage forms including tablets, granules, crystals, powdersor pellets. Coating is a process by which the outer covering of a tablet is layered or coated with a substance that offers competent benefits over the uncoated variety. Pharmaceutical Manufacturing Steps In continuous manufacturing, raw materials and energy feed into the system at a constant rate, and at the same time, a continual extraction of output products is achieved. Drug manufacturing is the process of industrial-scale synthesis of pharmaceutical drugs as part of the pharmaceutical industry.The process of drug manufacturing can be broken down into a series of unit operations, such as milling, granulation, coating, tablet pressing, and others. To do this spraying guns are used. The cause of this difficulty may be due to tablet size and possibly bitter taste of the drug. Required fields are marked *, 717, Janki Centre, Off Veera Desai Road Andheri (W), Mumbai 400053. The film coating process begins with the loading of a batch of tablets into the coating drum. Pharmaceutical industry and unit process 1. The coating process is important step in the manufacture of modern pharmaceutical tablets. Quality by design approach was explored to optimize the tablet coating process using Opadry®, an optimized one step film coating system. Mixing efficiency of the coating pan also decreases with partially loaded pans, requiring an increased rotation speed of the coating drum. A customer-oriented conception of our machines & facilities is as naturally as a strict compliance with current GMP design requirements & … Although this pharmaceutical process has been around for almost a century yet, it continues to be a crucial aspect of the modern medicine making process with advanced machinery and technologies. Conversely, if the guns and the spray widths are too wide, there would be overlap of spray area – some spray may hit non targeted areas such as the door or drum wall. This is important especially for functional such as enteric coatings where increased rotation can cause edge wear on the tablets leading to failure during disintegration tests. This is a predictable scenario in many households where kids dislike taking medicines due to its awful taste. Senior Citizens and children find it difficult to swallow or gulp some oral dosage forms. At the same time, the process machine is based on the proven patented L.B. The coating process is important step in the manufacture of modern pharmaceutical tablets. Product Description . The first requirement during the coating process is that the coating suspension must be distributed evenly on the tablet bed. In context with these criteria, our specific process know-how for mixing, processing & coating systems is the basis of innovative systems for the pharmaceutical industry. This risk can be mitigated by coating to contain one of the two or by coating a pellet previously compressed into a core. The secret of film coating is very similar to spray-painting – it is best to spray lightly and evenly so that successive thin coatings are allowed to build up to create a robust dense layer on the surface of the tablet. Please use the form below to get in touch. During the coating process, the pressure in the drum should always be less than the inlet air pressure. The coating itself can serve several functions – it can strengthen the tablet, control the release of active ingredients, improve its taste, provide colour, make it easier to package and handle, and protect it from moisture. A process where a thin polymer-based layer having a thickness between 20 and 100 µm is applied to the OSD which may be a tablet, granules or pellets is called film coating. The coating itself can serve several function – it can strengthen the tablet, control the release of active ingredients, improve its taste, provide colour, make it easier to package and handle, and protect it from moisture. Coating pans are used mostly to sugar coat pellets. This results in wastage of the coating material and may lead to other problems such as picking and sticking. There are two types of coating machines used in the pharmaceutical industry: coating pans and automatic coaters. As the water or solvent evaporates from the mist, it leaves the solids behind to form a thin film. It is a single-stage process that is faster and increases the tablet weight marginally by only 2-3% in comparison with the sugar coating process, which results in an addition of 60 to 80% additional weight. What is pharmaceutical manufacturing • it is the process of industrial scale synthesis of pharmaceutical drug by pharmaceutical companies. Then, manufacturers introduced side-vented perforated coating drums. We are all for the automated coating systems with 21 CFR part 11 compliance. This unpleasant taste or odour can be taken care off by adding film-forming agents, taste-masking agents, flavouring agents, along with the coating ingredients. They include.

Before starting the spraying process, it is important to set up the guns correctly and carry out validation of the sprays to make sure that there is a minimum variation between the guns. JavaScript seems to be disabled in your browser. Listing of Alarms, warnings & safety interlocks expected with specific and immediate action such as cycle stop, operator alert etc. The use of stabilizers added to the coating ingredients help to protect drugs from light sensitivity, moisture and drugs that degrade due to atmospheric oxidation. The modern coating pan is usually a perforated rotating drum that is housed within a cabinet. The cabinet provides the means of controlling the environment within the drum i.e., temperature and pressure, air flow rate and rotational speed of the drum. Monitoring the spray delivery rate, is crucial especially in aqueous film coating as variations in the spray rate during the coating process can lead to several problems, such as picking and sticking, orange peeling and frosting.and erosion, all of which are caused by over-wetting of the tablets. Originally, the coating process was performed in solid coating pans. Different uses that include trays, tables, rollers, sealing tools and molds. Milling, granulation, coating, and tablet pressing are all potential parts of the process. The coloured API migrates easily to stain the patient’s clothes and hands. The modification is effective with osmotic release oral delivery systems, enteric (delayed-release) or sustained-release coating.
