[1]パロノセトロンまたはその薬学的に許容される塩と、ニコチン酸アミドを含有する、パロノセトロン含有液体組成物。
[2]ニコチン酸アミドを0.01〜40mg/mL含有する、[1]に記載のパロノセトロン含有液体組成物。
[3]ニコチン酸アミドを、パロノセトロン1質量部に対し、0.05〜250質量部含有する、[1]または[2]に記載のパロノセトロン含有液体組成物。
As a result of the study by the present inventors, it has been found that when nicotinamide is used as an additive, the stability of the palonosetron-containing liquid composition is excellent.
That is, the present invention has the following aspects.
