Special Issue "Pharmaceutical Solid Forms: From Crystal Structure to Formulation".

Area of Science:

• Pharmaceutical Sciences
• Drug Development
• Materials Science

Background:

• Significant effort is needed to transition a therapeutic molecule from discovery to a viable drug product.
• The structural characteristics of an active pharmaceutical ingredient (API) are fundamental to its successful formulation.
• Early-stage structural elucidation of APIs is often underestimated in the drug development pipeline.

Discussion:

• This Special Issue emphasizes the importance of pre-formulation structural characterization of APIs.
• Investigating API solid-state properties, polymorphism, and degradation pathways is vital.
• Connecting molecular structure to macroscopic formulation behavior is a key challenge.

Key Insights:

• Proactive structural analysis of APIs mitigates formulation risks and development delays.
• Knowledge of API structure informs excipient selection and manufacturing process design.
• Robust characterization ensures API stability, bioavailability, and therapeutic efficacy.

Outlook:

• Future research should focus on advanced analytical techniques for rapid API structural assessment.
• Integrating computational modeling with experimental data can predict formulation outcomes.
• Standardizing pre-formulation characterization protocols will accelerate drug development timelines.
