A film coating is a thin polymer-based coat that is typically sprayed onto solid pharmaceutical dosage forms, such as tablets, capsules, pellets or granules.Film coating can impact both its appearance and its pharmacokinetics making it an essential process in making the final drug product.
Coating polymer material coated around core. Deposition of liquid polymer coating around core by polymer adsorbed at the interface formed between core material and vehicle phase. Rigidization of coating: coating material is immiscible in vehicle phase and is made rigid. This is done by thermal, cross-linking, or dissolution techniques.
Pharmaceutical 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.
There are two types of coating machines used in the pharmaceutical industry: coating pans and automatic coaters. [14] Coating pans are used mostly to sugar coat pellets. Automatic coaters are used for all kinds of coatings; they can be equipped with a remote control panel, a dehumidifier, and dust collectors.
Sputter coating in scanning electron microscopy is a sputter deposition process [clarification needed] to cover a specimen with a thin layer of conducting material, typically a metal, such as a gold/palladium (Au/Pd) alloy. A conductive coating is needed to prevent charging of a specimen with an electron beam in conventional SEM mode (high ...
Capsule fill weight is a critical attribute in encapsulation and various real-time fill weight monitoring techniques such as near-infrared spectroscopy (NIR) and vibrational spectroscopy are used, as well as in-line weight checks, to ensure product quality. [7]
An enteric coating is a polymer barrier applied to oral medication that prevents its dissolution or disintegration in the gastric environment. [1] This helps by either protecting drugs from the acidity of the stomach, the stomach from the detrimental effects of the drug, or to release the drug after the stomach (usually in the upper tract of the intestine). [2]
Drug packaging (or pharmaceutical packaging) is process of packing pharmaceutical preparations for distribution, and the physical packaging in which they are stored.
