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.
