The primary purpose of reconciling drug usage during a study is to ensure compliance with the protocol. This step is vital in clinical research as it involves comparing the amount of study drug dispensed to participants with the amount returned or accounted for.

Ensuring compliance is crucial for the validity of the study findings, as discrepancies in drug administration could lead to biased results or misinterpretations regarding the efficacy or safety of the treatment being investigated.

Compliance verification aids in maintaining the integrity of the trial and supports reliable data collection.
