coating process in pharmaceutical industry

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). High Efficiency Tablet Film Coating Machine In Pharmaceutical Industry . Automatic coaters are used for all kinds of coatings; they can be equipped with a remote control panel, a dehumidifier, and dust collectors. Mixing efficiency of the coating pan also decreases with partially loaded pans, requiring an increased rotation speed of the coating drum. The only control available for a 2-port gun is the pressure of air on the one port. Most often these are atomizers that use compressed air to atomize the coating solution or suspension. The drug release profile can be modified and or controlled. Subscribe to our blog to receive all updates directly in your mailbox. 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. 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. enhances mechanical properties (abrasion & compressibility), improves aesthetic appeal (Texture, appearance, odour and taste), and. There are three common atomizer gun types – 2-port, 3-port and 4-port. 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. This risk can be mitigated by coating to contain one of the two or by coating a pellet previously compressed into a core. 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. Sun Coating Company provides many different coating processes to the pharmaceutical industry. What is pharmaceutical manufacturing • it is the process of industrial scale synthesis of pharmaceutical drug by pharmaceutical companies. Film Coating Process In The Pharmaceutical Industry The coating process is important step in the manufacture of modern pharmaceutical tablets. The modification is effective with osmotic release oral delivery systems, enteric (delayed-release) or sustained-release coating. In 2011, L.B. 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. In essence, this blog on Pharmaceutical Coating discusses the need and the process carried out for coating. The following are the process parameters to be monitored, validated and set for a product to get quality products with maximum yield. 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. leads to an improvement in the overall flowability. It also allows embossing or printing on the tablet. Originally, the coating process was performed in solid coating pans. During the coating process, the pressure in the drum should always be less than the inlet air pressure. Your email address will not be published. There are two types of coating machines used in the pharmaceutical industry: coating pans and automatic coaters. 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. 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. The film coating process begins with the loading of a batch of tablets into the coating drum. 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. 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. They include. offers protection from unstable or reactive substances, affecting through the air, humidity light and oxidation etc. Peristaltic pumps are very easy to clean and tubes can be changed easily, to minimize cross contamination between different coating materials. A customer-oriented conception of our machines & facilities is as naturally as a strict compliance with current GMP design requirements & … 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 pharmaceutical coating can be applied to a wide range of Solid Oral Dosage forms including tablets, granules, crystals, powdersor pellets. It is important therefore to keep a check on the pressure within the drum during a coating operation.

At the start of operations, the spray rate should be checked for each gun and recorded. Contact Us sales@suncoating.com 734-453-0822 By checking the first 3 to 5 batches in this way, the rotation speed of the peristaltic pump can be verified. 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. The coating of OSD in pharmaceuticals has been practised since time immemorial. 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? This usually takes about 15 minutes. Senior Citizens and children find it difficult to swallow or gulp some oral dosage forms. We started with our precision tablet press tooling, but since then, we’ve grown into a global presence for supplying tablet coating equipment.We’ve become an industry leader in tablet coating systems by never being satisfied and always reaching for higher quality. 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. Sugar coating was one of the earliest methods developed to coat tablets and is still practised for some products, especially confectionery. We are all for the automated coating systems with 21 CFR part 11 compliance. To get the required spray width, it is important to optimize the gun-to-gun distance and the gun-to-bed distance. The first requirement during the coating process is that the coating suspension must be distributed evenly on the tablet bed. 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. produces controlled and sustained release, thereby improving the drug dissolution.

Film coating has evolved with time, keeping pace with demands of the pharma industry. 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. • 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. However, it is very capital intensive and requires a massive facility for production. Depending on the application, a humidifier or dehumidifier may also be necessary. Milling, granulation, coating, and tablet pressing are all potential parts of the process. 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). This results in wastage of the coating material and may lead to other problems such as picking and sticking. Do defects occur when the drum is first loaded or when rotated? Quality by design approach was explored to optimize the tablet coating process using Opadry®, an optimized one step film coating system. Risk of interaction between two incompatible substances.

The “RECIPE” can be automated based on operations with different user levels such as operators, Supervisor and Manager. 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. Different Active Pharmaceutical Ingredients and (excipients) have different tastes or odour, some may be mildly bitter, yet some of them may be very bitter. 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. 3. This field is for validation purposes and should be left unchanged. Drum loading—when tablets are first loaded, check broken, capped or chipped tablets. Please use the form below to get in touch. 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. At the same time, a positive pressure in the drum must also be avoided as this may cause contamination of the environment when the drum door is opened due to the release of dust particles and hot air, both of which are prohibited by GMP. 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 sugar-coating process involves a skilled manipulative operation and could last for 3 – 5 days. Nowadays, pharmaceutical film coating represents a significant process step in the pharmaceutical industry. Balancing both spray rates and drying conditions to achieve good coating process efficiency (typically > 90% and ideally > 95%). PHARMACEUTICAL MANUFACTURING 2. © Fabtech Technologies International Ltd. If the guns are too close, the spray width would be narrow resulting to non-uniform coating. The pharmaceutical coating can be applied to a wide range of Solid Oral Dosage forms including tablets, granules, crystals, powdersor pellets. However, high negative pressures must be avoided to ensure that some spray is not lost via the air exhaust port. This article describes the essential process steps and equipment required for film coating tablets. During the coating process, the pan must be fully or optimally loaded to prevent air from going straight to the bed to the exhaust duct, and thereby waste of energy and reducing drying efficiency. Tablet Flowing Issues Troubleshooting Guide. Sugar Coating is largely borrowed from the confectionery industry which had developed this technique and is still widely used today. 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. 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. 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. Coating pans are used mostly to sugar coat pellets. The coating process involves an iterative application of sucrose based solution to the tablet within the coating pan.
