Upon attempting to design a pharmaceutical preparation by mixing minoxidil with a general thickening agent during a process for considering a minoxidil-containing composition for an agent for external use in which dripping is inhibited, it was discovered that the pharmaceutical preparation would have sediments or would cloud and that a sufficient viscosity of the pharmaceutical preparation could not be obtained. The minoxidil-containing composition for an agent for external use of the present invention is characterized by containing minoxidil (a), a hydroxypropyl cellulose and hypromellose (b), ethanol (c), and water (d). Said composition is clear and has a good feel upon use, and dripping of the composition is inhibited.已知於抑制液體滴下之含有敏諾西代(minoxidil)之外用劑組成物之檢討過程，摻混敏諾西代(minoxidil)與一般黏稠劑，嘗試製劑設計時，製劑發生沈澱物或混濁，進而不能得到充份的製劑黏性。含有(a)敏諾西代(minoxidil)、(b)羥丙基纖維素及甲基羥丙基纖維素(hypromellose)、(c)乙醇、及(d)水為特徵之本發明之含有敏諾西代(minoxidil)之外用劑組成物係可抑制液體滴下之澄清且使用感良好之含有敏諾西代(minoxidil)之外用劑組成物。
