Co-spray Drying Drugs with Aqueous Polymer Dispersions (APDs)-a Systematic Review.

Area of Science:

• Pharmaceutical Sciences
• Materials Science
• Chemical Engineering

Background:

• Aqueous colloidal dispersions of water-insoluble polymers (APDs) are advantageous due to their avoidance of organic solvents and efficient processing characteristics.
• APDs are widely used in pharmaceutical coating of tablets and multiparticulates via pan and fluidized-bed equipment.
• Co-spray drying presents an alternative processing method for APDs and drugs in aqueous systems.

Purpose of the Study:

• To systematically review the applications and potential of co-spray drying drugs with APDs.
• To highlight the advantages of co-spray drying for drug delivery systems.

Main Methods:

• Systematic review of published research articles.
• Analysis of co-spray drying processes involving APDs and drugs.

Main Results:

• Co-spray drying enables the one-step manufacture of capsule- and matrix-type microspheres.
• This method allows for controllable microsphere size and improved processing characteristics.
• The resulting microspheres are suitable for further formulation into various dosage forms.

Conclusions:

• Co-spray drying drugs with APDs is a promising technique in drug delivery.
• It offers a versatile and efficient approach for creating advanced drug delivery systems.
