Dosage Regimen: Fixed Dose01:01

Dosage Regimen: Fixed Dose

Fixed-dose regimens are a common approach to administer drugs to achieve and maintain desired levels of the drug in the body. In this dosing strategy, a specific amount of medication is given at regular intervals, often multiple times a day, to ensure a consistent drug concentration in the bloodstream.
Fixed-dose regimens can be used for various routes of administration, including intravenous (IV) injections and oral medications. For IV administration, a predetermined amount of the drug is...
Dosage Regimen: Individualization01:24

Dosage Regimen: Individualization

Individualization in dosing regimens is the customization of medication doses for individual patients. Its necessity arises from the goal of maximizing therapeutic benefits while minimizing risks. This approach is pivotal because human responses to drugs can vary widely; what is effective for one person may be inadequate or excessive for another. Interpatient (intersubject) variability refers to differences in drug responses between individuals, while intrapatient (intrasubject) variability...

Dose Size and Dosing Frequency: Determination Methods

Determining the optimal dose size and dosing frequency in pharmacotherapy is crucial for achieving therapeutic effectiveness while minimizing adverse effects. This article explores the methodologies employed in determining these parameters, focusing on their significance and interplay to tailor dosing regimens.Dose Size: Dose size refers to the amount of a drug administered in a single dose. It is determined based on the drug's pharmacodynamics and pharmacokinetics properties and...
Determination of Multiple Dosing Parameters: Loading and Maintenance Doses01:25

Determination of Multiple Dosing Parameters: Loading and Maintenance Doses

A loading dose is an essential pharmacological strategy to rapidly achieve the target plasma drug concentration necessary for an immediate therapeutic effect. This approach is especially critical for drugs characterized by slow absorption or extended half-lives, where delaying therapeutic plasma levels could compromise treatment outcomes. By administering a loading dose, clinicians ensure a prompt onset of drug action, even for agents with complex pharmacokinetic profiles.Achieving steady-state...
Rational Dosage Regimen: Maintenance Dose and Loading Dose01:24

Rational Dosage Regimen: Maintenance Dose and Loading Dose

A rational dosage regimen considers a drug's pharmacokinetics, including its absorption, distribution, metabolism, and elimination from the body. By understanding these factors, the appropriate dosage can be determined, and the dosing schedule can be designed to achieve and maintain the desired therapeutic effect while minimizing adverse effects.
In most cases, drugs are administered repetitively or infused continuously to maintain a steady-state concentration in the body. At a steady state,...
Drug Dosing in Renal Diseases: Dose Adjustments Based on Drug Clearance and Elimination Rate Constant01:25

Drug Dosing in Renal Diseases: Dose Adjustments Based on Drug Clearance and Elimination Rate Constant

In patients with renal disease, dosage adjustments are necessary to maintain therapeutic plasma drug concentrations and prevent toxicity or subtherapeutic exposure. Renal impairment alters drug pharmacokinetics, especially in conditions like uremia, where changes such as prolonged elimination half-life and altered apparent volume of distribution can significantly affect drug disposition. These changes require careful modification of the dosing regimen to achieve the desired clinical...

Summary

Dose standardization for expensive anticancer drugs was assessed. Standardized rounded doses (SRD) were proposed for six of nine drugs, improving productivity and organization in cancer centers.

Area of Science:

  • Oncology
  • Pharmacoeconomics
  • Healthcare Management

Background:

  • Traditional body size-based dosing for anticancer drugs faces criticism.
  • Alternative strategies like flat-fixed dosing are under consideration but not widely adopted.
  • Dose standardization offers a rational approach to chemotherapy dose calculation.

Purpose of the Study:

  • To assess the dose standardization of expensive anticancer drugs.
  • To evaluate the quality and economic benefits of dose standardization.
  • To develop a new method for dose standardization based on prescription and economic criteria.

Main Methods:

  • A novel dose standardization method, derived from dose-banding, was developed.
  • Feasibility was studied in two French cancer centers (Institut Curie and Hôpital Saint-Louis).
  • Nine candidate drugs were selected, and standardized rounded doses (SRD) were proposed using theoretical and practical approaches.

Main Results:

  • Standardized rounded doses (SRD) were successfully proposed for six out of nine selected drugs.
  • The proposed SRD were implemented with the agreement of medical staff.
  • SRD were rounded to the nearest vial size or combined from available strengths, facilitating practical application.

Conclusions:

  • Dose standardization aids in optimizing productivity within hospital pharmacy preparation units.
  • Implementation of SRD improves the overall organization of chemotherapy preparation processes.
  • This approach offers a practical solution for rationalizing expensive anticancer drug dosing.
