Problems solved by technology

[0009] Yet solution is because its residence time in affected part is few, and drug action time is short, and curative effect is poor; Milk / ointment adopts oily base, has greasy feeling, is difficult to clean, and patient is inconvenient to use, and milk / ointment adopts more generally. Dispersed system, easy to stratify during storage, which affects the use and efficacy; and suppositories are easy to deteriorate due to the matrix, easy to deform at high temperature, poor retention in the vagina, and short drug action time, making it difficult to release all the drugs. There is a foreign body sensation, easy to damage the vaginal mucosa, easy to contaminate clothes after use, etc., and the use and efficacy of drugs are also seriously affected
[0010] At present, there is no report about ciclopirox olamine gel and its preparation method
