Problems solved by technology

The reason is that while reducing IOP, these drugs can also reduce the blood flow of visual organs such as the retina and cause poor nutrient supply, thereby reducing visual function.
Like timolol eye drops in the treatment, there will also be side effects of slowing down the heart rate

Abstract

An eyedrops of kakonein for preventing and treating glaucoma contains kakonein, cosolvent, antioxidizing agent, metal complex, osmotic pressure regulator, antiseptic, pH regulator, and distilled water. Its advantages are high curative effect, low by-effect, and protecting vision.

Description

technical field [0001] The invention belongs to the field of medicines, in particular to a puerarin eye drop. Background technique [0002] Glaucoma is one of the common geriatric diseases, and about 2% of people over the age of 40 suffer from this disease. With the aging of the population, the incidence rate increases year by year. Although glaucoma can be treated surgically, drug prevention and treatment is still one of the important means. Some glaucoma drugs currently on the market usually only lower intraocular pressure (IOP). Therefore, after the patient is given the drug, although symptoms such as headache are alleviated due to the reduction of IOP, the visual acuity continues to decline. The reason is that while reducing IOP, these drugs can also reduce the blood flow of the retina and other visual organs, resulting in poor nutrient supply, thereby reducing visual function. Like timolol eye drops in the treatment, there will be a side effec...
