Isotonic vs. Isosmotic: Know the Difference
By Shumaila Saeed || Published on January 14, 2024
Isotonic solutions have equal solute concentration and osmotic pressure as another solution, while Isosmotic solutions have equal osmotic pressure regardless of solute composition.
Key Differences
Isotonic solutions maintain the same solute concentration as another solution, preventing cellular osmotic imbalance. Isosmotic solutions, despite similar osmotic pressures, may differ in solute composition.

In Isotonic conditions, cells neither swell nor shrink due to osmosis, maintaining cellular integrity. Isosmotic conditions imply equal osmotic pressures but do not guarantee identical solute types or concentrations.

Isotonic
(physiology) Of or involving muscular contraction against resistance in which the length of the muscle changes. Antonym is isometric. Isotonic movements are either concentric (working muscle shortens) or eccentric (working muscle lengthens). See also Wikipedia:Isotonic (exercise physiology)

Isotonic
Having an osmotic pressure (tonicity) equal to that of a reference solution; - of aqueous solutions. Contrasting with hypotonic and hypertonic. See hypertonic.
A knowledge of the colligative properties of solutions . . . is essential for one to understand fully the principles involved in rendering intravenous solutions isotonic with blood serum, or opthalmic solutions isotonic with lachrymal fluid. Solutions thus adjusted produce less shock and much less irritation than those which are hypotonic or hypertonic, and present-day practise recognizes the desirability of making the necessary adjustments whenever possible.
