What is NOT one of the four types of medication dosing?

Population-based dosing is not typically classified as one of the standard types of medication dosing in the context of chemotherapy and other treatments. The four main types of medication dosing primarily include fixed doses, weight-based doses, and body surface area (BSA) doses.

Fixed doses refer to a set amount of medication administered regardless of patient-specific factors. Weight-based doses involve calculating the medication dosage based on the patient's body weight, which is particularly common in pediatric patients and certain adult treatments to ensure accuracy in dosing based on size.

Body surface area dosing takes into account the total surface area of the patient, which can provide a more tailored approach for medications that have a broad therapeutic range or are impacted heavily by the patient’s size.

In contrast, population-based dosing would generally mean calculating a dose based on studies and data from a broad population rather than individual characteristics, which does not fit into the established categories used to ensure accuracy and safety in medication administration.
