Emulsomes: new lipidic carriers for drug delivery with special mention to brain drug transport

Abstract

Abstract Background Emulsomes are a type of lipid-based nanoparticle that consists of a solid lipid core surrounded by a phospholipid bilayer and have shown promise as drug delivery systems for a variety of applications. The major advantageous aspect of employing lipid-based carriers is their ability to enhance the solubility and bioavailability of poorly water-soluble drugs, mandatorily in case of intranasal drug delivery. These structures have portrayed significant ability to encapsulate drug with poor water solubility and low oral bioavailability, further leading to a completely enhanced drug delivery systems for achieving stability and controlled release of drug. The selection of lipid components and their physiochemical properties can be tailored to optimize drug solubility, blood brain barrier permeability, and enhanced targeting. Main body of abstract Intranasal drug delivery systems offer several advantages over other routes of administration. Intranasal delivery of drugs can provide rapid and efficient absorption into the bloodstream, bypassing first-pass metabolism in the liver and potentially reducing the risk of systemic side effects. Nasal mucosa comprises of dense network of blood vessels, that allow much enhanced rapid drug absorption and direct systemic delivery once the medication is being insufflated through the nasal route. Emulsomes can be used to encapsulate a wide range of drugs, including hydrophobic compounds that are difficult to formulate using traditional delivery methods. By incorporating targeting ligands or other components into the emulsome structure, it is possible to create formulations that are highly selective for specific tissues or cells. The characterization parameters majorly particle size, zeta potential, and encapsulation efficiency play a significant role while demonstrating the effectiveness of emulsome formulation and further its nasal route of administration. Therefore, by assessing and evaluating the parameters, researchers could effectively gain insights into the quality, stability, and enhanced therapeutic effects of emulsome drug carrier, leading to impactful information which would help in future intranasal emulsome preparation preparations, optimization and ensuring the overall effectiveness of the drug delivery systems. Short conclusion This review discusses the idea of emulsomes drug delivery systems, reviews the effectiveness of emulsomes for the delivery of small molecules, and pays particular attention to its structural and formulation design including benefits of intranasal emulsome delivery with recent advancements, stability aspects, and various considerations related to drug delivery and comprising of future prospects.
