Pharmacology

Pharmacology is a branch of science about medicinal substances, called
pharmaceuticals, or simply "drugs". The field encompases drug composition,
drug properties, interactions, toxicology, and desirable effects that can be
used in therapy of diseases.

Greek : pharmacon - drug, logos - science.

Medication drugs have to be approved by drug regulatory authorities. This
field is called regulatory affairs. The International Conference on
Harmonisation works in the standardisation for this.

There are various classification systems for medicinal products including
ATC classification.
