Isotonic Solution

An Isotonic Solution is a type of solution that has the same osmotic pressure as the cells or body fluids with which it is in contact. In simpler terms, the concentration of solutes (like salts or sugars) in the solution is equal to that of the body's cells, which means that it does not cause any water to move in or out of the cells. This balance makes isotonic solutions particularly useful for medical and emergency purposes, especially for hydration, irrigation, and eye care.

Eye Washes: Isotonic solutions are commonly used for eye irrigation because they match the body's natural tear composition, helping to wash out irritants or chemicals from the eye without causing further irritation or discomfort. For example, Eyesaline® is a buffered, isotonic saline solution commonly used in eyewash stations.
