This post contains short Pharmaceutics one-liners that help B.Pharm and D.Pharm students revise key topics in a simple way.

Usually water or low-molecular-weight alcohols or compounds, used in topical applications and in wet granulation, for the production of tablets.

moistening agents

Dosage form comprising several elements (e.g., microspheres or coated pellets) dif- fering in the rate of drug release.

multi compartment formulation

Consists of several different layers that are compressed on top of each other, to form a single tablet composed of two or more layers.

multilayer tablet

Device that disperses liquids to aerosols for therapeutic use by inhalation through a mask.

nebulizer

Greasy, semi-solid preparation for external application, often anhydrous, containing dissolved or dispersed medicaments.

ointment

Kinetic model, where the whole body is thought of as a single compartment in which a substance is dis- tributed rapidly, achieving an equilibrium between blood and tissue immediately.

one-compartment model

Time required to achieve the minimum effective plasma concentration following administration of the dosage form.

onset of drug action

Process of agglomeration that converts fine powders or granules of bulk drugs and excipients into small, free-flowing, spherical, or semi-spherical units, referred to as pellets.

pelletization

Science of preparation of drugs, dosage forms, and drug delivery systems taking into account the pharmacokinetics and pharmacodynamics of the drug as well as its physical and chemical properties.

pharmaceutics

#10

Solid material that exists at least in two different molecular arrangements, i.e., distinctly different crystal species.

polymorph

#11

Transition of a solid crystalline phase to another phase having the same chemical composition but a dif- ferent crystal structure.

polymorphic transition

#12

Existence of two or more different crystal structures for the same compound.

polymorphism

#13

Defined for powders used pharmaceutically, according to particle sizes. 

powder grades

#14

Dry solid material consisting of many, usually free flowing, fine particles.

powder

#15

Exploratory activity that begins early in pharmaceutics, involving studies designed to determine the compatibility of excipients with the active substance for a biopharmaceutical; physicochemical and bioanalytical investigation
