Having a linear scale, distortion of your curve as a consequence of tolerance advancement is well seen. Even so, given that the dose-reaction curve is often presented utilizing a logarithmic dose scale, this has also been adopted below.

Definition: Posology is usually a branch of clinical science that offers with the dose or quantity of drugs administered to the affected person to acquire the desired pharmacological action.
