Spray drying is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas. Applications of Spray Drying include enhanced solubility and bioavailability of API, encapsulation, powders for inhalation and aseptic production. These spray dying applications produce Amorphous Spray Dried Dispersions, Nano composites, Aseptic products and excipients for food and pharmaceutical industries. Freund-Vector’s VSD-200 offers Amorphous Spray Dried Dispersions.
Amorphous Spray Dried Dispersions
Solid dispersion is defined as the dispersion of one or more active ingredients in an inert excipient or matrix (carrier), where the active ingredients could exist in finely crystalline, solubilized or amorphous state. (Sareen et al., 2012; Kapoor et al.,2012). Spray drying of API and carrier polymer which are dissolved in a common solvent, leads to the formation of homogeneous, stable dispersion of amorphous drug molecularly dispersed in polymer matrix.
The illustration below portrays the Freund-Vector Amorphous Spray Dried Dispersion process.
