Overview on Emulgel and their marketed Formulations

Abstract

Background: Emulgel is a topical preparation prepared by the mixture of an emulsion and a gel. Emulgel is considered as one of the most important topical delivery systems because it consists of two release control systems, i.e., a gel and an emulsion. The primary intention of this new topical delivery system is to deliver hydrophobic drugs into systemic circulation through the skin. By applying a suitable statistical design, different grades of emulgel can be prepared. There are various favorable properties. Therefore, emulgel is considered as the most conventional system available in the market over other topical drug delivery systems. Objectives: In the present work an attempt was made to prepare emulgel of garlic oil and ajwain oil for enhancing its topical delivery. Material and Method: Emulgel formulation was characterized by various parameters like pH, viscosity, spredability, Extrudability, microbiological Assay.
