- drugs produce their effects by interacting with specific molecular targets in the body
- the effects of drugs are determined by their chemical - structures and alterations of the structure of a drug are likely to affect its action
- there is a definite relationship between the amount or dose of a drug and its effect.

- Chemical name (e.g. acetylsalicylic acid)
