Tablet coating is a new type of drug designed to be more effective and beneficial. The film coating process can be widely used in tablets, pills and granules, especially for traditional Chinese medicine tablets with strong hygroscopicity, easy cracking and mottled, showing its superiority. Compared with sugar coating, film coating mainly has the following advantages:
1. Good quality. Since the film-forming agent and most auxiliary additives are polymer materials with excellent physical and chemical properties, the film-coated tablets can not only be moisture-proof, light-proof, taste-masking, and wear-resistant, but also not easy to mildew and disintegrate. The dissolution rate, bioavailability and validity period of drugs greatly expand the countries and regions where drugs can be sold, and effectively promote the export of drugs, especially Chinese patent medicines.
2. Less weight gain. The weight of the tablet core is only increased by 2% to 4%, while the sugar-coated tablet (the main excipient is the talc that has been eliminated abroad) can often increase the weight of the tablet core by 50% to 100%.
3. Fast drying. The coating operation time is short, generally only 2 to 3 hours, and the sugar coating generally takes 16 hours. It is easy to operate and easy to master, especially for Chinese and Western medicines that are easily damaged by high temperature.
4. The image is beautiful. The film is beautiful in shape, bright in color, fresh in logo and vivid in image. The drug core can adopt various flat and curved shapes, and the company's trademark and logo can be directly punched on the drug core, which is still clear and obvious after wrapping the film coating, which can not only improve the corporate image, but also play an anti-counterfeiting role.
KimaCell HPMC is widely used for the tablet coating across countries, is water-soluble and soluble in solvents mixtures. Used primarily for storage and protection of tablets and pellets, Hypromellose HPMC, a nonionic, does not react with APIs, but works compatibly with such additives as colorants, lubricants, plasticizers, and opacifiers.
KimaCell HPMC improves printability that would facilitate the logo-making process, making the tablets distinctive.
