Formulation And Evaluation of Emulgel from Pongamia Oil

Topical administration of therapeutic agents offers numerous advantages over oral and intravenous methods, allowing for targeted drug delivery to specific anatomical sites within the body. Emulgel, innovative dual-controlled release systems formed by blending emulsions and gels, represent a promising approach in topical drug delivery. Emulsions, such as oil-in-water and water-in-oil formulations, and gels each possess unique properties conducive to drug delivery. Emulgel combine the benefits of both, providing enhanced skin permeation, easy removal, and adjustable viscosity and appearance. Incorporating hydrophobic drugs, Emulgel offer advantages in dermatology, including compatibility with various excipients, cost-effectiveness, and improved patient acceptability. Pongamia pinnata, commonly known as the Pongam tree, is a versatile plant with significant medicinal properties. Found abundantly in India and other regions, its various parts have been utilized in traditional medicine for treating diverse ailments such as cancer, skin disorders, and diarrhoea. Phytochemical analysis reveals the presence of several bioactive compounds, including flavonoids and fatty acids. Pharmacological studies demonstrate its anti-inflammatory, anti-diarrheal, anti-plasmodial, and antioxidant activities, indicating its potential in therapeutic applications. A novel Emulgel formulation containing karanjin was prepared using a method involving the dispersion of polymers in water, adjustment of pH, and the creation of aqueous and oil phases, followed by blending and evaluation. Evaluation parameters included patch tests for sensitivity, viscosity analysis, Spreadability assessment, pH testing, and inspection of physical appearance. The results demonstrate the feasibility and potential of the Emulgel formulation for topical drug delivery, offering enhanced properties.
