Abstract:
An object of the present invention is to provide a microneedle array which is capable of suppressing aggregation of liposomes in a case where a water-soluble polymer is mixed with liposomes during production of the microneedle array and is capable of localizing a drug at a tip of a needle. According to the present invention, provided is a microneedle array including: a sheet; and a plurality of needles which are present on an upper surface of the sheet, in which each needle contains a water-soluble polymer, a drug, a liposome, and a salt, a zeta potential of the liposome is −10 mV or less, the zeta potential is a zeta potential of a liquid obtained by diluting the liposome to 0.1 mg/mL with 10 mmol/L of a phosphoric acid aqueous solution having a pH of 7, and a content of the salt in a portion of each needle which contains the liposome is 2.5 mmol/g or less.

Claim (Index 12):
The microneedle array according to  claim 1 ,\n wherein the salt is a salt containing at least one selected from the group consisting of a sodium ion, a potassium ion, an ammonium ion, a lithium ion, and a silver ion.
