An excipient is a substance formulated alongside the active ingredient of a medication.They may be used to enhance the active ingredient’s therapeutic properties; to facilitate drug absorption; to reduce viscosity; to enhance solubility; to improve long-term stabilization (preventing denaturation and aggregation during the expected shelf life); or to add bulk to solid formulations that have ...
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. Coatings are necessary for tablets that have an unpleasant taste, and a smoother finish makes large tablets easier ...
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]
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.
In addition to its use in ophthalmic liquids, hypromellose has been used as an excipient in oral tablet and capsule formulations, where, depending on the grade, it functions as controlled release agent to delay the release of a medicinal compound into the digestive tract. [15] It is also used as a binder [16] and as a component of tablet coatings.
Cellulose acetate phthalate (CAP), also known as cellacefate and cellulosi acetas phthalas, is a commonly used polymer phthalate in the formulation of pharmaceuticals, such as the enteric coating of tablets or capsules and for controlled release formulations.
Macrogol is used as an excipient in pharmaceutical products. [6] Lower-molecular-weight variants are used as solvents in oral liquids and soft capsules, whereas solid variants are used as ointment bases, tablet binders, film coatings, and lubricants. [23] For example, PEG-2000 is one of the excipients in the Moderna COVID-19 vaccine. [24] [25]
Special coatings can make the tablet resistant to the stomach acids such that it only disintegrates in the duodenum, jejunum and colon as a result of enzyme action or alkaline pH. Pills can be coated with sugar, varnish, or wax to disguise the taste. Pharmaceutical ingredients such as APIs can also be coated with a ResonantAcoustic mixer for ...
