Mechanisms Involved in Drug Entrapment and Release: Understanding the mechanisms of drug entrapment and release is crucial for optimizing the performance of microsponges in drug delivery applications.

Drug Entrapment: The process of drug encapsulation within microsponges can be achieved through several methods, including:

Solvent Evaporation: In this method, a solution containing the polymer and the drug is prepared. Upon evaporation of the solvent, microsponges are formed with the drug entrapped within their structure.

Coacervation: This involves the phase separation of the polymer solution, leading to the formation of microsponges. The drug can be incorporated into the coacervate, resulting in a stable encapsulation.

Spray-Drying: A solution of the polymer and drug is sprayed into a hot chamber, leading to rapid evaporation of the solvent and the formation of microsponges ⁷.

The choice of method influences not only the efficiency of drug loading but also the stability of the encapsulated drug, which is critical for maintaining its therapeutic efficacy.

Drug Release Mechanisms: The release of drugs from microsponges can occur through various mechanisms:

Diffusion: The primary mechanism by which drugs are released involves the diffusion of drug molecules from the core of the microsponges through the polymer matrix into the surrounding medium. The rate of diffusion is influenced by factors such as drug solubility, molecular weight, and the thickness of the polymer matrix.

Erosion: Over time, the polymer matrix can degrade or dissolve, resulting in the release of the encapsulated drug. This process can be influenced by environmental factors such as pH and temperature, making it important for achieving predictable release profiles.

Swelling: Upon contact with moisture, microsponges may absorb water and swell, creating channels that facilitate drug diffusion. This can enhance the release rate, particularly for hydrophilic drugs ⁷.

The interplay between these mechanisms allows for the design of microsponges that deliver drugs in a controlled and sustained manner, optimizing therapeutic effects while reducing the frequency of application.

Types of Active Ingredients Compatible with Microsponges: Microsponges are highly versatile and can accommodate a wide range of active ingredients, allowing for customized formulations based on the therapeutic needs of patients.

Hydrophilic Drugs: These are compounds that readily dissolve in water, typically requiring specific formulation strategies to ensure effective encapsulation and release.
