An Innovative Approach as Self-Emulsifying Drug Delivery System for Phytoconstituents

Abstract

In recent years, herbal drugs have flourished as the method of rehabilitation of choice in numerous parts of the world and most of populations consider them as alternative conventional medicaments. However, most of the herbal drugs show poor solubility and bioavailability, which ultimately leads to diminished efficacy and frequency of administration. Consequently, self-emulsifying drug delivery system has been highlighted for poor water-soluble herbal medicaments. Self-emulsifying drug delivery system is an isotropic mixture of phytoconstituents, oil, surfactant, and cosurfactant, and subsequent to oral administration spontaneously endures self-emulsification and forms without emulsion as soon as it comes in contact gastric fluid. Most of the researchers and industrialists are attracted towards this novel and emerging technology as it offers various advantages. The chapter focuses on the mechanism of self-emulsifying, benefits of herbal SEDDS, factors affecting herbal SEDDS with formulation and characterisation of it.
