Water for injection is generally made by distillation or reverse osmosis. [5] It should contain less than a mg of elements other than water per 100 ml. [5] Versions with agents that stop bacterial growth are also available. [5] In the UK, some hospitals offer subcutaneous injections of water directly for treating back pain in labour.
D50 – 50% dextrose in water; The percentage is a mass concentration, so a 5% glucose/dextrose solution contains 50 g/L of glucose/dextrose (5 g per 100 ml). This usage is imprecise but widely used, as discussed at Mass concentration (chemistry) § Usage in biology. Glucose provides energy 4 kcal/gram, so a 5% glucose solution provides 0.2 ...
[18 F]Fluorodeoxyglucose (), or fluorodeoxyglucose F 18 (USAN and USP), also commonly called fluorodeoxyglucose and abbreviated [18 F]FDG, 2-[18 F]FDG or FDG, is a radiopharmaceutical, specifically a radiotracer, used in the medical imaging modality positron emission tomography (PET).
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Clearance of a substance is sometimes expressed as the inverse of the time constant that describes its removal rate from the body divided by its volume of distribution (or total body water). In steady-state, it is defined as the mass generation rate of a substance (which equals the mass removal rate) divided by its concentration in the blood .
The definition of the topical route of administration sometimes states that both the application location and the pharmacodynamic effect thereof is local. [ 3 ] In other cases, topical is defined as applied to a localized area of the body or to the surface of a body part regardless of the location of the effect.
The USP Controlled Room Temperature is a series of United States Pharmacopeia guidelines for the storage of pharmaceuticals; [1] the relevant omnibus standard is USP 797. [2] [3] Although 100% compliance remains challenging for any given facility, [4] the larger protocol may be regarded as constituting a form of clean room [5] which is included in a suite of best practices.
In the pharmaceutical industry, drug dissolution testing is routinely used to provide critical in vitro drug release information for both quality control purposes, i.e., to assess batch-to-batch consistency of solid oral dosage forms such as tablets, and drug development, i.e., to predict in vivo drug release profiles.
