The invention relates to a
Ziconotide temperature-sensitive
nasal spray, which comprises a
solvent, and
Ziconotide, a first matrix, a second matrix, an absorption
enhancer, a pH buffer
system and a polypeptide stabilizer dispersed in the
solvent, the first matrix is
poloxamer 407, and the second matrix is
poloxamer 188; the temperature-sensitive
nasal spray comprises the following components in percentage by
mass: 5%-20% of the first substrate, 0-5% of the second substrate, 0.01%-10% of the absorption
enhancer, and the balance of the temperature-sensitive
nasal spray, the pH buffer
system is an
acetic acid-acetate
system or a
lactic acid-lactate system. The
ziconotide temperature-sensitive nasal spray can form a good spray form through a nasal spray device, the
viscosity has a temperature-sensitive characteristic, and the
ziconotide temperature-sensitive nasal spray is not easy to lose and has good stability.
