Abstract

Insights

Standardized terms for medication review activities were developed to improve research consistency. This international taxonomy will help compare medication review services and their impact effectively.

Area of Science:

  • Pharmacology
  • Health Services Research
  • Clinical Pharmacy

Background:

  • Medication review (MR) is a critical process for assessing drug safety and effectiveness.
  • Inconsistent terminology in MR research hinders comparisons between studies and understanding of service impact.

Purpose of the Study:

  • To establish an international taxonomy of standardized terms and activity definitions for medication reviews.

Main Methods:

  • A three-stage Delphi consensus study involving international medication review experts.
  • Systematic review to identify MR activity terms, followed by expert rating and feedback on a Likert scale.
  • Consensus defined as 75% panel agreement, with iterative refinement of definitions based on feedback.

Main Results:

  • Seven experts from four countries participated.
  • Consensus was reached on terms including 'Medication' as a descriptor.
  • Key MR activity terms agreed upon: discontinue medication, start medication, dose increase, dose decrease, dosage form change, medication safety and efficacy monitor, and Educate.

Conclusions:

  • A standardized set of medication review activity terms and definitions has been selected for global adoption.
  • This standardization will enable meaningful comparisons of process evaluations across diverse settings in future MR research.

Drug Nomenclature01:17

Drug Nomenclature

During the development of a new pharmaceutical, the manufacturer initially assigns a code name to the drug. Once approved, the drug receives a United States Adopted Name (USAN)—a generic, nonproprietary designation. Upon being listed in the United States Pharmacopeia, this nonproprietary name becomes the drug's official name. Additionally, the manufacturer assigns a proprietary name or trademark, which serves as the brand name under which the drug is marketed. It is worth noting that...

Drug Regulation01:25

Drug Regulation

Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...

Drug Classes and Categories01:25

Drug Classes and Categories

Drugs can be classified according to their chemical composition or their intended therapeutic application. For instance, anti-infective agents that possess the ability to eliminate pathogens or suppress their growth and reproduction can be grouped based on the organisms they target or their chemical structure. Furthermore, drugs can be divided into prescription, nonprescription, or controlled substances. Prescription medications, such as antibiotics, require oversight from a licensed healthcare...

Drug Administration and Therapy Phases: Overview

Drugs, the chemical agents used in diagnosing, treating, or preventing diseases, undergo a four-phase process of development: pharmaceutic, pharmacokinetics, pharmacodynamics, and therapeutic.
The pharmaceutical phase focuses on leveraging the physicochemical properties of the drug to design and manufacture an effective product. Variants include orally administered tablets or capsules, topical creams or ointments, and parenteral-delivery solutions or emulsions.
The pharmacokinetic phase...

Drug Dosage Regimen: Overview01:15

Drug Dosage Regimen: Overview

A drug dosage regimen describes the specific instructions and schedule for administering a drug to a patient. It considers factors such as drug dosage, frequency, route of administration, and duration of treatment. Designing an appropriate dosage regimen for a patient aims to achieve a target drug concentration at the site of action.
Typically, the starting dose and dosing interval are guided by the manufacturer's recommendations based on clinical trials conducted during and after drug...

Prescription, Nonprescription and Orphan Drugs

Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...
