in different aspects of tablet coating. They tumble on a rotating drum while a coating liquid (solution, dispersion, or melt) sprays through nozzles onto their surface. Tablets that are compressed are coated with sugar layer and may be colored or uncolored depending on the tablet’s purpose. Tablet coating is one of the oldest pharmaceutical processes still is existence. Tablet coating machines are used to coat the surface of tablets with a thin coating of film. Basic principles involved in tablet coating Tablet coating is the application of coating composition to moving bed of tablets with An electrostatic dry coating process based on a liquid pan coater was developed for enteric coating of tablets with Eudragit® L 100-55. Tablet coating machine. enteric coating and enteric polymers. They tumble on a rotating drum while a coating liquid (solution, dispersion, or melt) sprays through nozzles onto their surface. This is a defect where the coating peels away from the. The process involves spraying of a solution of polymer. Tablet 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 over uncoated variety. This video explains sugar coating of pharmaceutical tablets. A limit on the water level for the coated tablet was also set at NMT 1.8% w/w to ensure that any water picked up by the tablets during coating was removed.Effectiveness of this coating approach to achieve acceptably low water level in the coated tablets is shown in Fig. RESEARCH AND REVIEWS: JOURNAL OF PHARMACY AND PHARMACEUTICAL SCIENCES Techniques of Tablet Coating: Concepts and Advancements: A Comprehensive Review, Tablet Coating techniques: Concepts and recent trends, RECENT ADVANCEMENT IN TABLET COATING TECHNOLOGY, Tablet coating Industry point view-A comprehensive view, Processing technologies for pharmaceutical tablets: A review, Appraisal on: Tablet coating and its outcome with complementary sprouting technology. Scuffing of Film-coated Tablets Scuffing of Film-coated Tablets Scuffing involves the generation of gray-to-black marks on the surface of white (or lightly colored) film-coated tablets, thought to be an abrasion interaction between titanium dioxide in the coating and the stainless steel pan walls Tablet is most commonly used pharmaceutical dosage form which has ease of administration. To enhance ease of swallowing large dose forms. Tablet film coating is a common but critical process providing various functionalities to tablets, thereby meeting diverse clinical needs and increasing the value of oral solid dosage forms. Tablet coating increase the cost of formulation. The advantages of tablet coating are taste masking, odor masking, physical and chemical protection, protection of the drug from the gastric environment etc. Tablet film coating is a common but critical process providing various functionalities to tablets, thereby meeting diverse clinical needs and increasing the value of oral solid dosage forms. Appraisal On : Tablet Coating and Its Outcome with Complementary Film coating of pharmaceutical dosage forms, such as tablets and pellets, can be used to tailor the drug release profile. An ideal tablet should be free from any visual defect or functional defect. It also provides good appearance to tablets. air, moisture and light) in order to improve stability. The amount of coating on the surface of a tablet is critical to the effectiveness of the oral dosage form. The optimized dry powder coating method produces capsules with smooth surface, correct coating uniformity and release profile that are corresponding to that of the tablet cores. Tablet coating is the application of a coating composition in a moving bed of tablets with the concurrent use of heated air to facilitate the evaporating of the solvent and with the intention of conferring benefits and properties to the dosage form over the uncoated variety. Int J Pharm. Any film-coating formulation consist mostly of a polymer, colorant, plasticizer, and solvent (or vehicle). Tablet coatings must be stable and strong enough to survive the handling of the tablet, must not make tablets stick together during the coating process, and must follow the fine contours of embossed characters or logos on tablets.
