Which property of Glycerine (Osmoglyn) makes it effective in aqueous humor reduction?

Glycerine, also known as Osmoglyn, is effective in reducing aqueous humor primarily due to its hypertonic nature. When administered, it creates a hypertonic environment in the plasma compared to the intraocular fluid. This osmotic gradient promotes the movement of water out of the aqueous humor, thereby decreasing the overall volume and pressure within the eye.

The hypertonic property means that glycerine has a greater concentration of solutes compared to the surrounding fluid, which draws water out of the body tissues and into the bloodstream. This mechanism is particularly useful in managing conditions such as glaucoma, where reducing intraocular pressure is essential.

While other properties such as anti-inflammatory, diuretic, and antiviral may contribute to the overall therapeutic effects of different medications, they do not directly relate to the mechanism by which glycerine effectively reduces aqueous humor. Thus, the hypertonic characteristic is the key reason for its effectiveness in this context.
