Drug(s) or formulation(s) of drug(s) or dosage forms, which no longer have patent protection.
Technological process consisting of the application of a substance, which forms a layer (e.g, to protect the drug and/or the tablet, to mask taste, to control the rate of drug release (e.g., film coating, sugar coating).
Term that describes a solid of regular shape and the presence of three-dimensional order on the level of atomic dimensions, for a given molecule.
Reversal of coagulation or flocculation, i.e., the dispersion of aggregates to form a stable colloidal suspension or emulsion.
Substance that absorbs sufficient moisture from the atmosphere to dissolve itself.
Biologically active substance, which when biodistributed in the body is expected to modify one or more of its functions.
Sophisticated dosage form, which, by its construction, is able to modify/control the availability of the drug substance to the body by temporal or spatial considerations.
Substance that loses water to form a lower hydrate or becomes anhydrous spontaneously.
Sweet (often colored) dilute alcohol-based, “hydroalcoholic”, liquid used in the compounding of drugs to be taken by mouth in order to improve palatability.
Delivery of a generally sterile liquid medication into the body, or a vessel, tissue, or organ via syringe and needle.
The process of separating the lighter particles of a powder from the heavier ones by means of an up- ward-directed stream of fluid (gas or liquid).
Fluid colloidal dispersion system in which liquid droplets and/or liquid crystals are dispersed in a liquid.
Aggregates of colloidal dimensions (i.e., association of colloids) formed reversibly from amphiphile molecules.
Liquid intended for massaging into the skin.
Denotes a dispersed phase having a pronounced affinity for the dispersion medium.
Tendency of a substance to absorb water from the atmosphere.
Tablet, which does not contain a disintegrant and which is sucked to dissolve in the mouth to produce either a local (e.g., antiseptic) or systemic (e.g., vitamins) effect.
Release of a drug from a dosage form that it is not immediate (e.g., sustained release, retarded release, delayed-action preparations, controlled release, extended release, etc.).
Consists of several different layers that are compressed on top of each other, to form a single tablet composed of two or more layers.
Specific case of drug embedding in insoluble excipients (typically in a polymer) in order to achieve ex- tended release.
