Comparative evaluation of drug interaction publications--1976

Area of Science:

• Pharmacology
• Drug Safety
• Information Science

Background:

• Accurate drug interaction information is crucial for patient safety and effective pharmacotherapy.
• Numerous reference books exist to guide healthcare professionals in identifying potential drug interactions.
• The comparative utility and comprehensiveness of these resources require systematic evaluation.

Purpose of the Study:

• To assess the usefulness of key drug interaction reference books for retrieving and applying critical information.
• To determine if reviewed publications provide sufficient data to confirm suspected drug interactions.
• To evaluate the general format and features of each reference resource.

Main Methods:

• A systematic review of prominent drug interaction reference books was conducted.
• Twenty specific drug combinations with known or suspected interactions were analyzed.
• Each book was assessed for the inclusion of necessary information to verify interactions and for overall usability.

Main Results:

• The American Pharmaceutical Association's Evaluations of Drug Interactions and Hansten's Drug Interactions were highly rated across all criteria.
• Stockley's Drug Interactions and their Mechanisms was found to be comprehensive and authoritative, closely following the top-rated references.
• Cohen's Drug Interactions, Gant's Drug Interaction Index, and Hartshorn's Handbook of Drug Interactions were considered valuable supplementary resources for verifying less common interactions.

Conclusions:

• The American Pharmaceutical Association's and Hansten's references are primary resources for reliable drug interaction data.
• Stockley's provides a strong, authoritative alternative or supplement.
• Other reviewed handbooks serve as useful secondary checks for clinical suspicion.
