Patent ID: 8865654

Claim:
An eye drop comprising (i) an acetate of a peptide having an amino acid sequence represented by Ser-Ser-Ser-Arg and (ii) a hydrochloride of a peptide having an amino acid sequence represented by Phe-Gly-Leu-Met-NH 2 , wherein (a) a concentration ratio of the acetate of a peptide having an amino acid sequence represented by Ser-Ser-Ser-Arg to the hydrochloride of a peptide having an amino acid sequence represented by Phe-Gly-Leu-Met-NH 2 is 1/15 to 1/50; (b) the acetate of a peptide having an amino acid sequence represented by Ser-Ser-Ser-Arg has a concentration of 0.001 to 0.3% (w/v); (c) the hydrochloride of a peptide having an amino acid sequence represented by Phe-Gly-Leu-Met-NH 2 has a concentration of 0.015 to 1.5% (w/v); and (d) the eye drop has a pH of 2.5 to 6.5.
