What is the purpose of the WHO Drug Dictionary?

The purpose of the WHO Drug Dictionary is to classify drug names into common preferred terms. This classification serves to create a standardized vocabulary that can be consistently used across different clinical trial contexts and international borders. By providing a common reference point for drug names, the dictionary aids in the clear and unambiguous identification of medications, which is crucial for the integrity of clinical data and communication among researchers, healthcare providers, and regulatory authorities.

Standardizing drug terminology helps in minimizing confusion that may arise from the use of different brand names or generic names for the same drug, which can vary by country or region. This consistency is vital in clinical trials, ensuring that data collected is comparable and manageable, ultimately facilitating the review process for drug safety and efficacy by regulatory bodies.

The other options do not describe the primary function of the WHO Drug Dictionary. Although recommendations for treatments, standardization of clinical trial procedures, and the approval of new drug applications are critical components of drug development and clinical research, they fall outside the scope of what the WHO Drug Dictionary directly addresses.
