Classifications of Drugs:
There are several classifications based on various characteristics of drugs:
- by chemical structure;
- origin (natural, synthetic and mineral);
- by pharmacological groups - the most common classification in Ukraine, based on the drug effect on the human body;
- nosological classification – based on classification of diseases for which treatment is used.
Medications can be classified according to their use or function, the system that they treat and their chemical makeup. For example, they can be classified according to system, as follows:
respiratory medications
cardiac medications
nervous system medications, etc.
They can also be classified according to their function or use. For example, they can be classified as below:
nonsteroidal anti-inflammatory medications
narcotic analgesics
antidepressants, etc.
Lastly they can be classified according to their chemical makeup. Examples include:
aminoglycosides
estrogens
opioids, etc.
Most of the medications within a classification group, like alpha-adrenergic blockers, are quite similar although they are not identical. Classification systems enable us to identify the similarities and differences among a large number of medications within and outside of a particular classification.
