Abstract: Most of the new drug candidates and present ones are lipophilic, which leads to low bioavailability.
Self-emulsifying drug delivery systems (SEDDS) have emerged as promising formulation
system for poorly water-soluble drug candidates. Over the last two decades, various such drug compounds
were used by researchers for the development of SEDDS. At present, many SEDDS formulations
are also available in the market. Though SEDDS offer many advantages but drawbacks like low
drug loading, few dosage form choices, difficulty in handling and storage led to the solidification of
this system by various methods. Solidification by spray drying technique offers a lot of advantages like
scalability and stability. This particular method is the focus of this review. Adsorbent carriers have the
most significant role in the fate of this formulation and its compatibility with the drug candidate. This
review addresses the advantages, method of development, spray drying specifications, and characterization
of S-SEDDS in detail. Furthermore, the prospect of turning spray-dried SEDDS into tablets by
punching which offers potential advantages of increased bioavailability and stability has also been
discussed.
