Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to an isoconazole nitrate lipid nanoparticle cream and a preparation method thereof. Background technique [0002] Skin fungal infection is the abbreviation of a large class of infectious diseases such as skin, mucous membranes, hair and nails caused by fungi. This disease belongs to common disease and frequently-occurring disease, and the crowd prevalence rate can be as high as more than 20% in hot and humid areas. Research shows that the overall dermatology drug market ranks ninth in the global drug market, with a market size of US$11 billion. In my country, the incidence rate of skin diseases is very high. According to relevant statistics, the national total prevalence rate is 1.23%, that is, about 16 million people suffer from various degrees of skin diseases. [0003] There are many kinds of pathogenic bacteria that cause skin fungal infections. According to the different ...
