This application relates to the field of veterinary drug technology, and discloses a transdermal absorption-enhancing ointment and its preparation process. The ointment components include white petrolatum, anhydrous lanolin, caprylic / capric triglycerides, hydrophobic fumed silica, and a highly fluid active permeation-enhancing phase. The permeation-enhancing phase contains active drugs and soybean lecithin, which self-assemble to form an inverse micelle aggregate.
