Abstract
Spray drying is the
most widely used techniqueintended for drying of pharmaceutical products as
well as manufacturing of powder with desired
characteristics.It is a continuous
operation in which almost any pumpable liquid can be converted into a free
flowing powder. Considering uniformity of formed particles and well-control on particle size, spray drying is efficiently applicable in the drug delivery systems. This
method has found to be a potential way for systematic delivery of therapeutic
peptides, proteins and also antibiotics. Methods: In this study, the procedures and aplications of spray drying were
reviewed and the effect of diffirent affecting parameters was explained. Results:
Spray drying is extensively used to dry heat sensitive products like
enzymes and proteins with minimum loss on activity and produce drugs with
improved solubility as well as drying of
nanoparticles, microencapsulation, granulation and coating beyond its
well-known background on drying of liquids
