Compound sodium chloride eye drops

Abstract

The invention discloses compound sodium chloride eye drops comprising the components of: sodium chloride, potassium chloride, sodium bicarbonate, hydroxypropylmethyl cellulose, an antiseptic of ethylparaben, and a solvent of water. According to the compound sodium chloride eye drops provided by the invention, a proper amount of hydroxypropylmethyl cellulose is used for regulating the viscosity, and ethylparaben is adopted as the antiseptic, such that the viscosity is appropriate, and a preservative effect is stable. The eye drops have properties similar to those of human body's own tear secretion. With the eye drops, moisture can be supplemented for eyes, eye surface can be moisturized, and a mucinous water-absorbent solution is formed and covered on the surface of eyes, such that eyes can be protected, and patient symptoms can be ameliorated. The eye drops can be used for effectively relieving and treating xerophthalmia.

Description

technical field [0001] The invention belongs to the technical field of medicines, and relates to an artificial tear, in particular to a compound sodium chloride eye drop. Background technique [0002] Tears are an innate protective mechanism of human beings. It contains lysozyme to reduce the damage of infection or other harmful substances on the surface of the eyeball to a certain extent. In addition, it can keep the corneal surface smooth and produce clear vision, and form a thin tear film on the corneal epithelium to continuously moisten and lubricate the eyeball, making the eyes feel comfortable. [0003] Keratoconjunctivitis sicca (also known as dry eye) is one of the most common diseases in ophthalmology clinics. The main symptoms are foreign body sensation, burning sensation and general eye discomfort. These discomforts are typically described as a scraping sensation, dry eyes, pain, grittiness, stinging or burning. [0004] In recent years, supplementing artificia...

AI Technical Summary

Problems solved by technology

[0005] However, the residence time of artificial tears known in the prior art on the cornea is relatively short

Therefore, it is necessary to apply the artificial tear treatment agent at regular intervals on the eyes as the case may be, which is too cumbersome and uncomfortable for the patient. Some gel-like therapeutic agents are difficult to provide sufficient oxygen to the cornea. In addition, the osmotic pressure, pH value, viscosity, and electrolyte concentration of existing artificial tears are different from those of human tears. Use will lead to the loss or destruction of the lipid layer of the ocular surface, which may further aggravate "dry eye patients with abnormal lipid layer"
