Abstract: The present invention relates to a formulation of Ivermectin in oral solution which allows proper absorption, enabling the drug to be consumed at any time. In particular, the oral lipid composition is designed with the appropriate selection of a medium-chain triglyceride oil, a hydrophilic cosolvent and an antioxidant, so as to influence the absorption/digestibility of the poorly water-soluble active ingredient and facilitate bioavailability and bioactivity for the administration of the oral solution in drops. The formulation includes Ivermectin in a lipid medium including a cosolvent and an antioxidant in combination with an oily solvent to form an oral solution for administration in drops. The field of the invention is related to improving the bioavailability of insoluble drugs such as Ivermectin for administration in oral drop forms based mainly on lipids without compromising stability or creating impurities.

Abstract: A resonant column device configured to perform a resonant column test on a specimen and measure an angular deformation of the specimen. The resonant column device has a housing mounted on a base, a specimen container within the housing, a cell wall surrounding the specimen container, a load frame within the housing with a support bar above the specimen container, a torque motor suspended from the support bar with a plurality of springs, and a laser deformation sensor within the housing outside of the specimen container. The specimen container is configured to hold the specimen during testing. The cell wall is configured to fluidly isolate the specimen container from an interior volume of the housing. The torque motor is configured to apply a torsional harmonic load to the specimen, and the laser deformation sensor is configured to measure an angular deformation of the specimen.
