It possesses the below-mentioned constitution, the solution for injection of ipamorerin and the transportation liquid: a) At 0.001% - 20% quantity ipamorerin which is solubilized, by approximately 2 mol equivalent acetic acids (ipamorerinjiasetato) and b) at least on the basis of the weight of the free base of ipamorerin with 3, at the same time, the water which is sufficient in order the mol excessive acid at the quantity which is sufficient in order to give the pH under 7 (is desirable and combination aid, and d of 0.1% - 30% one or more) to make 100% acetic acid), with in c) case (however, all percentages are based on the gross weight of the solution).下記の組成を有する、イパモレリンの注射用および輸液用の溶液:a)イパモレリンの遊離塩基の重量に基づいて0.001%~20%の量での、およそ2モル当量の酢酸によって可溶化されたイパモレリン(イパモレリンジアセタート)、b)少なくとも3で、かつ、7未満のpHを与えるために十分な量でのモル過剰の酸(好ましくは酢酸)、c)場合により0.1%~30%の1つ以上の配合助剤、および、d)100%にするために十分な水(ただし、すべての百分率は溶液の総重量に基づく)。
