Pharmaceutical Investigations: Drug-Specific Problems Create Substantial Obstacles (First Part)
In the realm of clinical trials, ensuring the safety and integrity of investigational drugs is of paramount importance. However, challenges persist in the nomenclature, labeling, and packaging of these drugs, potentially leading to errors and compromising participant safety.
One such issue is the difficulty in accessing necessary information from multi-language paper labels attached to investigational drug containers. The strong adhesive and numerous pages can make it hard for trial participants or staff to find the information they need (Figures 8 and 9).
Another problem is the lack of lot numbers on investigational drug labels, hindering the tracking of drug identity, expired products, recalls, and adverse drug reactions. This omission can cause confusion and make it difficult to maintain accountability (Missing lot numbers).
Investigational drugs are often identified using a number preceded by an abbreviation of the sponsoring company's name. However, some labels include error-prone abbreviations or dose designations, such as U for units or trailing zeros (1.0 mg) (Unsafe abbreviations and dose expressions).
Moreover, those working on new drug development, product manufacturing, and protocols for clinical trials are not always well-versed in medication error-prevention principles. This lack of knowledge can contribute to mistakes in the handling, storage, and administration of investigational drugs.
Sponsors may not relabel oral products with updated expiration dates based on retesting, potentially leading to confusion about the expiration status of dispensed products (Missing expiration dates).
To address these issues, several strategies can be implemented. Firstly, a standardized nomenclature should be used, ensuring that the names for investigational drugs are clear, unique, and easy to understand. Adherence to established guidelines or regulations for drug naming is also crucial for maintaining consistency across trials.
Secondly, comprehensive labeling is essential. All necessary information, such as the drug name, dosage, and any relevant warnings or instructions, should be included on the label. The labels must also be clear and easy to read to prevent errors by trial participants or staff.
Thirdly, proper packaging is vital. Distinctive packaging that is easy to differentiate from commercial products can prevent accidental use outside the trial. Tamper-evident packaging can also enhance safety and prevent unauthorized access.
Fourthly, centralized management systems, such as digital tracking systems, can improve drug administration efficiency and safety by minimizing errors and ensuring compliance with trial protocols.
Fifthly, training and education are key. All staff involved in the trial should be educated on the proper handling, storage, and administration of investigational drugs. Participants should also be informed about the drugs they are using, including any risks or side effects to watch for.
Lastly, continuous monitoring and review are necessary. Regular inspections of drug storage facilities and trial sites should be conducted to ensure compliance with safety protocols. Robust systems for reporting adverse events and suspected unexpected serious adverse reactions should also be in place to ensure timely responses to safety issues.
By implementing these strategies, clinical trials can enhance the safety of investigational drugs, reduce errors, and protect participants. It is a collective responsibility to ensure the highest standards of safety and integrity in clinical trials, safeguarding the health and wellbeing of all involved.
