Coating powder, also known as film coating premix, is the raw material used for film coating. It is a premix in which various ingredients are scientifically and rationally matched, and some ingredients are pretreated and fully mixed.
Function of coating powder: film coating reduces the friction of tablets, making it easier for patients to swallow, and is suitable for surface coating of large tablets or capsules.
① Improve the appearance of drugs: solid preparations such as tablets and pills can be wrapped with a smooth coat to make the surface of the drug smoother, more delicate and beautiful, and improve patients' medication compliance.
② Mask the smell and taste of drugs: the coating film can effectively isolate the bitterness and odor of the drug, improve the medication experience, and is particularly suitable for antibiotics and vitamin preparations with strong taste.
③ Control drug release: by adjusting the thickness of the coating film or adding functional excipients, sustained release, controlled release or enteric effect can be achieved, so that the drug is released at a specific location or at a specific time, improving the efficacy of the drug, and is used for sustained-release tablets, enteric-coated capsules, and extended-release preparations.
④ Protect drugs: The coating film can isolate air and moisture to prevent drug decomposition or oxidation, such as acting as a protective coating for light-sensitive drugs and drugs that are susceptible to moisture.
