    摘要: This invention relates to a depot formulation comprising a biodegradable silica hydrogel composite incorporating a nucleotide or nucleoside analogue reverse transcriptase inhibitor, wherein the silica hydrogel composite is obtainable by mixing silica particles comprising said nucleotide or nucleoside analogue reverse transcriptase inhibitor and having a maximum diameter of ≤1 000 μm, as such or as a suspension, with silica sol wherein the hydrogel composite is non-flowing and structurally stable when stored at rest and shear-thinning when shear stress is applied by injection. The present invention also relates to use of the depot formulation for treatment of chronic viral infections and prevention of chronic viral reinfection. The present invention further relates to a prefilled syringes comprising said depot formulation.

    摘要: A method for producing a flowing silica composition including a sol-gel transfer, where redispersion is carried out. The redispersion includes adding, after having reached gel point of the sol-gel transfer, liquid into the gel formed by the sol-gel transfer, and the addition being made within a sufficiently short time period after reaching the gel point, to result, after mixing of the gel and the liquid, in a rheologically homogenous flowing silica composition, which is and remains injectable as such, or by short stirring
