Cocrystallization: Cutting Edge Tool for Physicochemical Modulation of Active Pharmaceutical Ingredients

Area of Science:

• Pharmaceutical Science
• Materials Science
• Chemical Engineering

Background:

• Cocrystallization modifies active pharmaceutical ingredient (API) physicochemical properties without altering therapeutic benefits.
• It's an integral part of drug development, yielding cocrystals with superior properties unobtainable by traditional methods.
• Cocrystals are solid materials with multiple components non-covalently bonded in a shared crystal lattice.

Purpose of the Study:

• To provide a comprehensive review of the cocrystallization technique.
• To discuss various synthesis approaches, mechanisms, and applications in drug delivery.
• To examine the regulatory perspective of cocrystal development.

Main Methods:

• Review of existing literature on cocrystallization.
• Analysis of synthesis strategies and mechanisms.
• Evaluation of cocrystal applications in drug delivery systems.
• Assessment of regulatory pathways for cocrystal approvals.

Main Results:

• Cocrystallization effectively modulates poor physicochemical properties of APIs, including solubility, permeability, and bioavailability.
• It offers solutions for poor mechanical properties and taste masking.
• Numerous cocrystal products have achieved regulatory approval and market entry, with others in clinical development.

Conclusions:

• Cocrystallization is a powerful and clinically relevant tool for pharmaceutical formulation.
• Continued research is inspired by the success and potential of cocrystals in improving drug delivery.
• The review covers background, synthesis, applications, and regulatory considerations for cocrystallization.
