Description

technical field [0001] The invention relates to medicines in the medical field, in particular to a small-capacity fluconazole injection with broad-spectrum antifungal effects and a preparation method thereof. Background technique [0002] Fluconazole (C 13 h 12 f 2 N 6 O) is a white crystalline powder, easily soluble in alcohol and slightly soluble in water. It is recorded in the Chinese Pharmacopoeia 2000 edition. It is a new type of triazole antifungal drug with broad-spectrum antifungal effect and can selectively inhibit Sterol synthesis by fungi, highly selective for inhibition of fungal cytochrome P-450-dependent enzymes. It has a good antibacterial effect on Cryptococcus and Candida in vivo and in vitro, and is the first choice for clinical antifungal infection. Because AIDS patients have low immunity and their mucous membranes are particularly susceptible to fungal infection, the drug can also be used as an adjuvant treatment for AIDS. [0003] Because of the ra...
