Poor Aqueous Soluble Drugs; Challenges and Solution to Overcome with Self-Emulsification Systems: A Systemic Review

Fat-based treatment delivery systems have shown great potential in considering the delivery of moderately soluble drugs only. The limited solubility of these molecules in water makes oral lipid-loving medications very difficult. Since, when it comes to oral administration of slightly water-soluble drugs, methods of delivery of fat-based drugs have shown an excessive amount of potential. The solubility phase, which may be a problem that limits the oral absorption rate of insufficiently soluble drugs in water, is eliminated when the drugs are pre-dissolved in oils, surfactants, lipid mixtures and surfactants. The choice of lipid excipients and the dosage form greatly affect the biopharmaceutical aspects of drug absorption and distribution in both the laboratory and In-vivo because oils differ not only in their structures and physicochemical appearance but also in their digestion and absorption pathway. SMEDDS or micro emulsifying auto emulsifying drug delivery systems have gained recognition for their ability to improve the solubility and bioavailability of easily insoluble drugs. In the current action, the micro- self-emulsifying drug delivery system (SMEDDS) has been developed to increase oral bioavailability and solubility rate for both lipophilic and hydrophilic drugs. The goal of the project is to develop a precisely optimized self-emulsifying drug delivery system (SMEDDS) poorly water-soluble drug. A preliminary screening was executed to identify the best mix of several excipients for the formulation. The significance of numerous independent variables on dependent (response) variables was examined using a 32 execute factorial design. Oil concentration and Smix ratio were the independent variables and dependent variables, which include emulsification time (s), drop size (nm), polydispersity index , and zeta potential (mV), studied in the current work.
