• To provide insights into designing advanced drug delivery systems using polymer-derived coacervates.

Main Methods:

• Review of literature focusing on structural design parameters (polymer concentration, structure, ratio, chain length).
• Analysis of environmental factors (salt, pH, temperature) influencing coacervate formation.
• Evaluation of various coacervate architectures (micelles, vesicles, gels) for drug delivery applications.

Main Results:

• Structural design factors are primary determinants of coacervate architecture, leading to diverse forms like micelles, vesicles, and gels.
• Coacervate architecture significantly modulates drug stability, release kinetics, and delivery efficiency.
• Tailoring coacervate structure enables optimization for various administration routes (oral, transdermal, invasive).

Conclusions:

• Understanding polymer structure-property relationships is key to designing effective coacervate drug delivery systems.
• Tunable coacervate architectures facilitate targeted and controlled drug release for enhanced therapeutic outcomes.
• This approach holds promise for advancing precision medicine through optimized drug delivery.
