With our expertise in spray drying technology, we offer tailored formulation development services to help you achieve optimal drug solubility and bioavailability.

What is SDD?

Spray drying is a technique widely used in the pharmaceutical industry to convert liquid formulations into dry powders. It involves atomizing a liquid feed solution into a fine mist and drying it rapidly by applying hot air. The result is a dry powder with enhanced stability, improved processability, and increased surface area.

Spray-dried dispersion (SDD) refers to a specific type of formulation produced by spray drying in which the active pharmaceutical ingredient (API) is dispersed in a polymeric matrix or carrier material. SDDs are commonly used to enhance the solubility and dissolution rate of difficult-to-solubilize drugs, resulting in improved bioavailability and therapeutic efficacy.
