  • Publication number: 20230405034
    Abstract: The present invention relates to a formulation of Ivermectin in soft capsules. In particular, the present invention relates to a formulation of Ivermectin in soft capsules which allows proper absorption in water, allowing the drug to be consumed at any time. Ivermectin, as an insoluble active ingredient, according to the invention, can be formulated in a liquid solution without compromising its stability and without creating impurities to form a suitable soft gelatin capsule. Therefore, the invention comprises a formulation comprising Ivermectin in a lipid medium which includes a surfactant in combination with an oily solvent, a co-surfactant and an oxidant, to form a soft capsule comprising a collagen coating, a plasticiser and gelatin. The field of the invention relates to improving the bioavailability of insoluble drugs such as Ivermectin for delivery in oral soft gelatin capsule forms.
