Eye drops containing a partial peptide of an insulin-like groth factor I (FGLM) and a tetrapeptide (SSSR)

摘要

The purpose of this invention is to maximize the efficacy of, minimize the incidence of adverse effects from, and improve the storage stability of eye drops that contain: a peptide (SSSR), the amino acid sequence of which is represented by Ser-Ser-Ser-Arg, or a pharmacologically-permitted salt thereof; and a peptide (FGLM), the amino acid sequence of which is represented by Phe-Gly-Leu-Met-NH2, or a pharmacologically-permitted salt thereof. The concentration ratio between the SSSR or pharmacologically-permitted salt thereof and the FGLM or pharmacologically-permitted salt thereof is between 1/15 and 1/50. The concentration of the SSSR or pharmacologically-permitted salt thereof is between 0.001% and 0.3% (w/v) and the concentration of the FGLM or pharmacologically-permitted salt thereof is between 0.015% and 1.5% (w/v). The pH of the eye drops is maintained between 2.5 and 6.5.
