    摘要: Injectable Ivermectin solution is safely administrable to humans and animals used the disclosed technology. A macrocyclic lactone cyclodextrin complex which is completely dissolvable or dissolved in water in a ratio of at least 10-20 milligrams of the macrocyclic lactone complex per 5 milliliters of water. The macrocyclic lactone cyclodextrin complex is non-toxic, without using organic solvents, and in embodiments, formed by adding a surfactant to the macrocyclic lactone complex to water. The macrocyclic lactone cyclodextrin complex is Ivermectin or an Ivermectin derivative in some embodiments. The cyclodextrin complex is 2-hydroxypropyl-beta-cyclodextrin in some embodiments of the disclosed technology. The surfactant can be polysorbate 80 and is in a ratio of 0.01% to 25%, by weight, to said water. The water soluble complexes can be added to the water. The water-soluble complexes can have at least one of an anti-parasitic, anti-viral and anti-cancer complex.

    摘要: The present invention relates to a pharmaceutical formulation with enhanced stability of a fusion protein dimer comprising a modified IL-2 protein and a CD80 protein. The fusion protein dimer comprising an IL-2 protein and a CD80 protein can not only activate immune cells owing to IL-2, but also effectively regulate Treg cells owing to CD80. When the formulation according to the present invention is applied to a fusion protein dimer comprising an IL-2 protein and a CD80 protein, the stability of the fusion protein dimer is significantly increased, and it can be used as a liquid formulation. Accordingly, the commercial applicability of the fusion protein dimer can be increased.
