Doseringsschemes

Doseringsschemes, commonly referred to in English as dosing schedules or regimens, describe the planned plan for administering a therapeutic agent. A scheme specifies the amount of drug to be given, the route of administration, how often it is given, the duration of treatment, and any adjustments based on response or tolerability. The goal is to achieve effective drug levels while minimizing toxicity.

Key components of a dosing scheme include the dose (how much), the route (oral, intravenous, topical, etc.), the frequency (how often), and the duration (how long). Many schemes also include provisions for loading or starter doses, maintenance doses, and criteria for titration or adjustment, such as changes in response, side effects, or laboratory values. Adherence considerations and timing relative to meals or circadian rhythms may also be specified.

Doseringsschemes vary by context. Fixed regimens use the same dose and interval for all patients. Weight-based or body surface area dosing adjusts the dose to individual characteristics. Other schemes employ titration to reach a target effect, or intermittent/continuous approaches for drugs requiring steady exposure, such as infusions or depot formulations.

Implementation relies on pharmacokinetic and pharmacodynamic principles, patient factors (age, organ function, pregnancy), and potential interactions. Regular monitoring guides adjustments and detects adverse effects. Proper dosing schemes aim to optimize efficacy, reduce toxicity, and support patient adherence, while remaining adaptable to clinical changes.
