2. Adjective. (context: of a medical solution) Having the same concentration of solutes as human blood. ¹

3. Adjective. (context: of two muscles) having equal tension ¹

4. Adjective. (physiology) Of or involving muscular contraction against resistance in which the length of the muscle changes. Antonym is isometric.

Medical Definition of Isotonic

1. A biological term denoting a solution in which body cells can be bathed without a net flow of water across the semipermeable cell membrane. Also, denoting a solution having the same tonicity as some other solution with which it is compared, such as physiologic salt solution and the blood serum.
