d) water.
15. The method of claim 1 , wherein the liquid pharmaceutical composition consists essentially of:
a) desmopressin acetate in an amount of about 0.05 mg/ml;
b) sodium benzoate in an amount of about 0.285% w/v;
c) benzoic acid in an amount of about 0.034% w/v; and
d) water.
16. The method of claim 1 , wherein the liquid pharmaceutical composition consists of:
a) desmopressin acetate in an amount of about 0.05 mg/ml;
b) sodium benzoate in an amount of about 0.285% w/v;
c) benzoic acid in an amount of about 0.034% w/v; and
d) water.
17. The method of claim 1 , wherein the liquid pharmaceutical composition is ready-to-use without dilution or addition of any further components to the liquid pharmaceutical composition.
18. The method of claim 1 , wherein the liquid pharmaceutical composition contains no more than 5% wt of total impurities and not more than 1% wt of each of the following impurities: [Asp 5 ]desmopressin, [Glu 4 ]desmopressin, [Gly 9 OH]desmopressin, [L-Arg 8 ] desmopressin, [Gln 4 (Acm)]desmopressin, [Asn 5 (Acm)]desmopressin, and [Gly 9 N(CH3) 2 ]desmopressin after stored at 40° C.±2° C. and 75±5% RH humidity for 6 months, wherein an amount of impurities is determined according to high-performance liquid chromatography (HPLC) method.
