In pharmacokinetics, the '''rate of infusion''' (or '''dosing rate''') refers not just to the rate at which a drug is administered, but the desired rate at which a drug ''should'' be administered to achieve a steady state of a fixed dose which has been demonstrated to be therapeutically effective.

It can be calculated as the steady-state concentration in the plasma multiplied by the clearance:
