Abstract

The invention provides a voriconazole suppository and a preparation method and application thereof. The suppository comprises an effective dose of voriconazole, a dispersion carrier and a matrix, wherein the matrix comprises a forming agent, an emulsifying agent and a suspension aid agent. The preparation method comprises the following steps of: dissolving or dispersing voriconazole in the dispersion carrier, and uniformly mixing with the molten matrix to obtain the suppository; or adding the dispersion carrier into the molten matrix, and adding the voriconazole powder and the suspension aid agent, and uniformly mixing to obtain the suppository. The voriconazole suppository is applied to rectal or gynecological cavity administration and to the therapy for local or whole-body deep fungus infection. The invention provides a safe and effective cavity or rectal administration drug form which avoids the first-pass effect of liver, directly reaches the focus, reduces the medicine dosage, isparticularly suitable for the therapy for local deep fungus infection in gynecological cavity, pelvic cavity, accessory and the like, and ensures little side effect and good curative effect.

Description

technical field [0001] The invention relates to a voriconazole suppository, a preparation method and application thereof. Background technique [0002] Due to the widespread use of antibiotics, the symbiotic relationship between bacteria and fungi has been destroyed. Various immunosuppressants, corticosteroids, and radiation therapy have reduced the body's resistance to fungi. Major surgery, organ transplantation, and AIDS that seriously damage the body's immune function The spread of infection will damage the body's immune system, significantly increasing the rate of deep fungal infection and its mortality. Therefore, effective control and treatment of fungal infections has important clinical significance. About 80 kinds of antifungal drugs have been used clinically so far. Among them, azole antifungal drugs are developing the most rapidly. Because of their good curative effect, low toxicity, oral administration and good tolerance, they are the main force of antifungal tr...
