Dry formulations are particularly well suited to formulating sensitive biological materials, and are required for use with modern drug delivery technologies.
Destructive enzymes, and chemical species are rendered immobile and harmless, by being fixed in the solid state following drying. Freeze drying, in particular is less damaging to labile bioproducts than other drying methods as it is performed at lower temperatures, also, processing in the absence of oxygen prevents oxidative reactions.
一.Preservation
Drying results increased shelf life, and a tremendous reduction in weight and volume. Further details of the effect of drying on product preservation can be found by clicking。
二.Inhalable Drugs
Dry particle formulations, such as those produced by spray drying, and SEDS, are required for emerging technologies which enable the delivery of drugs via the lungs, further details can be obtained by clicking。
三.Transdermal Delivery
Delivering drugs directly through the skin is particularly suitable for DNA vaccines。
