Abstract

The invention relates to anti-keratitis konjac glucomannan eye drops and a preparation method thereof. The preparation method of the anti-keratitis konjac glucomannan eye drops comprises the following steps: preparing paraffin wax emulsion, preparing sol, preparing sol emulsion, preparing konjac glucomannan drug-carrying microspheres and preparing the anti-keratitis konjac glucomannan eye drops. According to the anti-keratitis konjac glucomannan eye drops, konjac glucomannan is used as a main raw material and a carrier; the gelling property, water-retaining property, water solubility and anti-keratitis property of the konjac glucomannan are utilized, and voriconazole, ofloxacin and doxycycline are added, so that the anti-keratitis effect is comprehensively expressed; and the anti-keratitis konjac glucomannan eye drops are used for treating fungal keratitis. The konjac glucomannan drug-carrying microspheres have stable performances, and have high bioavailability, good anti-keratitis performance, good water solubility and good anti-inflammatory performance. According to the anti-keratitis konjac glucomannan eye drops, the used materials are simple; and the anti-keratitis konjac glucomannan eye drops have the advantages of convenience for taking the materials, toxin and no harms, no secondary pollution and the like.

Description

technical field [0001] The invention relates to an eye drop and a preparation method thereof, in particular to an anti-keratitis konjac glucomannan eye drop and a preparation method thereof. Background technique [0002] Fungal keratitis is an infectious corneal disease caused by pathogenic fungi with a high blinding rate. So far, more than 70 kinds of fungi have been found to cause corneal infection. According to the different pathogenic roles of fungi in eye infections, they are divided into two categories: filamentous fungi and yeasts. With the widespread use of broad-spectrum anti-inflammatory drugs, glucocorticoids and antiviral drugs in clinical practice, the incidence of fungal keratitis in China has gradually increased, and the disease has become more serious. Voriconazole is an imidazole antifungal drug, which can change the permeability of fungal outer membrane by inhibiting the activity of bacteriochrome synthase, and exert an anti-keratitis effect in an all-rou...
