A lecithin organogel ("LO") operates as a transdermal pharmaceutical delivery composition. In particular, the lecithin organogel comprises an internal oil phase containing oil-in-water ("O/W") and water-in-oil ("W/O") emulsifiers, and an aqueous phase comprising inorganic and organic hydrocolloids. The lecithin organogel may contain up to 80% additive ingredients, including biocompatible surfactants, nonpolar solvents, saturated fatty alcohols, moisturizers, preservatives or antimicrobials, and chelating agents.
