Abstract: Disclosed are a sustained release solid formulation comprising a drug, for example, oxycodone or its pharmaceutically acceptable salt, in a water-insoluble matrix, which comprises a wax type excipient and copovidone, and thus, has increased compressibility and fluidity and reduced adhesiveness, and a method of preparing the same.

Abstract: A inhibition method of target mRNA expression includes: (a) obtaining binding energy of a double combination section on a dsRNA sequence of all combination comprising complementary nucleotides to a random target mRNA; (b) dividing the binding energy into four sections on the dsRNA sequence of each combination to obtain a difference of the mean binding energy between each section and convert into a score of a relative combination energy pattern; (c) selecting siRNA whose inhibition efficiency to target mRNA is expected to be high by applying the converted score to the dsRNA sequence with other factors that affect the efficiency of siRNA; and (d) inhibiting target mRNA expression using the selected siRNA.
