Dose regimen is the planned schedule for administering a drug to a patient. It specifies the amount of drug given, how often it is administered, and the duration of treatment. The aim is to keep drug levels within the therapeutic range while avoiding adverse effects.

A dose regimen typically includes:

• Dose size
• Dosing interval
• Duration of therapy
• Route of administration

Selection of an appropriate dose regimen is important for achieving therapeutic benefit. Incorrect dosing schedules may lead to treatment failure or drug toxicity, especially for medicines with a narrow therapeutic index.
