This is a list of abbreviations used in medical prescriptions, including hospital orders (the patient-directed part of which is referred to as sig codes). This list does not include abbreviations for pharmaceuticals or drug name suffixes such as CD, CR, ER, XT (See Time release technology § List of abbreviations for those).
A structural analog, also known as a chemical analog or simply an analog, is a compound having a structure similar to that of another compound, but differing from it in respect to a certain component. [1] [2] [3] It can differ in one or more atoms, functional groups, or substructures, which are replaced with other atoms, groups, or ...
Abbreviations of weights and measures are pronounced using the expansion of the unit (mg = "milligram") and chemical symbols using the chemical expansion (NaCl = "sodium chloride"). Some initialisms deriving from Latin may be pronounced either as letters ( qid = "cue eye dee") or using the English expansion ( qid = "four times a day").

Nor is written directly in front of the stem name, without a hyphen between, unless there is another prefix after nor (for example α-).
The antiviral drug aciclovir (bottom), a nucleoside analogue that functions by mimicking guanosine (top) Nucleoside analogues are structural analogues of a nucleoside, which normally contain a nucleobase and a sugar. Nucleotide analogues are analogues of a nucleotide, which normally has one to three phosphates linked to a nucleoside.
Functional analogs are not necessarily structural analogs with a similar chemical structure. [1] An example of pharmacological functional analogs are morphine , heroin and fentanyl , which have the same mechanism of action, but fentanyl is structurally quite different from the other two with significant variance in dosage.
