The present invention relates to a nanosuspension formulation suitable for a progerinin drug, which is insoluble, and a preparation method therefor. Specifically, the progerinin nanosuspension according to the present invention is a vehicle composition for improving dispersive stability of a progerinin drug(a), which is insoluble, and employs hydroxypropylmethyl cellulose (HPMC)(b) or hydroxypropyl cellulose (HPC)(b'), TPGS(c) or sodium dioctyl succinate (DOSS)(c'), and potassium sorbate(d). A mixture thereof was subjected to wet-type ball milling in a Dyno-Mill chamber to prepare a white nanosuspension containing a progerinin drug with an average particle diameter of 100 nm to 300 nm. This nanosuspension exhibits uniform dispersibility of progerinin drug particles, minimal change in the size of drug particles even at low temperatures or severe environments, and excellent bioabsorption efficiency of the drug. Therefore, it can be widely used as an oral nanosuspension formulation to confirm the therapeutic effect of progeria.
