PharmDE

PharmDE evaluates drug–excipient compatibility and predicts incompatibility risks to support pharmaceutical pre‑formulation and Quality by Design (QbD) assessments.

Key Features:

• Comprehensive incompatibility database: Contains 532 data items extracted from 228 peer‑reviewed articles.
• Interaction rules: Implements 60 interaction rules derived from knowledge and formulation research experiences.
• Rule‑based incompatibility risk prediction: Uses the interaction rules to generate incompatibility risk evaluations.
• Similarity search data matching: Employs similarity search techniques to match and retrieve related incompatibility data.
• Database searching (Basic Search): Supports direct searches within the curated incompatibility database.
• Drug incompatibility risk evaluation: Provides systematic evaluation of incompatibility risk between specific drugs and excipients.
• Formulation incompatibility risk evaluation: Assesses overall incompatibility risk within a given formulation.

Scientific Applications:

• Drug–excipient compatibility evaluation: Identification and assessment of potential incompatibilities between active pharmaceutical ingredients and excipients.
• Pharmaceutical pre‑formulation and formulation design: Informing pre‑formulation decisions and formulation risk assessment based on curated evidence and rule inference.
• Quality by Design (QbD) risk assessment: Supporting QbD workflows by evaluating physicochemical property interactions and interaction risks.
• Literature-based evidence synthesis: Consolidation of scattered drug‑excipient incompatibility data from scientific literature for formulation research.

Methodology:

An AI‑based rule‑driven expert system integrates a curated database of 532 data items from 228 articles with 60 interaction rules and applies database searching, similarity search techniques, and rule‑based incompatibility risk prediction.
