Pharmaceutical Cocrystal: An Antique and Multifaceted Approach

Area of Science:

• Pharmaceutical Science
• Materials Science
• Drug Delivery

Background:

• Pharmaceutical cocrystals represent an innovative strategy to modify the physicochemical and mechanical characteristics of drug substances.
• Cocrystals are formed by combining an active pharmaceutical ingredient (API) with a pharmaceutically acceptable coformer.
• They are utilized to overcome challenges related to drug solubility, dissolution rates, mechanical properties, and overall stability.

Purpose of the Study:

• To provide a comprehensive overview of pharmaceutical cocrystal technology.
• To discuss the preparation, characterization, and regulatory considerations (USFDA) for cocrystals.
• To explore the application of Hansen solubility parameters in predicting cocrystal formation and the impact of cocrystals on drug properties and pharmacokinetics.

Main Methods:

• Review of existing literature on pharmaceutical cocrystals.
• Discussion of cocrystal preparation and characterization techniques.
• Analysis of the influence of cocrystals on drug solubility, pH dependence, and pharmacokinetic profiles, including drug-drug cocrystals and novel coformers like aerosil 200.

Main Results:

• Pharmaceutical cocrystals demonstrate the capability to fine-tune the physicochemical and mechanical properties of drug substances.
• Cocrystallization offers opportunities for creating patentable inventions.
• The therapeutic efficacy of drugs can potentially be enhanced through the development of drug-drug cocrystals.

Conclusions:
