1. a homogeneous mixture of one or more substances (solutes) dispersed molecularly in a sufficient quantity of dissolving medium (solvent).
2. in pharmacology, a liquid preparation of one or more soluble chemical substances, which are usually dissolved in water. For names of specific solutions, see under the name.

aqueous solution one in which water is used as the solvent.
BCG solution an aqueous suspension of bacille Calmette-Guérin for instillation into the bladder to activate the immune system in treatment of superficial bladder cancers. It reduces the risk of a subsequent bladder cancer developing, although the exact mechanism of action is unknown.
buffer solution one that resists appreciable change in its hydrogen ion concentration (pH) when acid or alkali is added to it.
colloid solution (colloidal solution) imprecise term for colloid (def. 3).
hyperbaric solution one having a greater specific gravity than a standard of reference.
hypertonic solution one having an osmotic pressure greater than that of a standard of reference.
hypobaric solution one having a specific gravity less than that of a standard of reference.
hypotonic solution one having an osmotic pressure less than that of a standard of reference.
isobaric solution a solution having the same specific gravity as a standard of reference.
isotonic solution one having an osmotic pressure the same as that of a standard of reference.
molar solution a solution in which each liter contains 1 mole of the dissolved substance; designated 1 M. The concentration of other solutions may be expressed in relation to that of molar solutions as tenth-molar (0.1 M), etc.
normal solution a solution in which each liter contains 1 equivalent weight of the dissolved substance; designated 1 N.
ophthalmic solution a sterile solution, free from foreign particles, for instillation into the eye.
saturated solution one in which the solvent has taken up all of the dissolved substance that it can hold in solution.
sclerosing solution one containing an irritant substance (sclerosing agent) that will cause obliteration of a space, as in sclerotherapy.
standard solution one that contains in each liter a definitely stated amount of reagent; usually expressed in terms of normality (equivalent weights of solute per liter of solution) or molarity (moles of solute per liter of solution).
supersaturated solution an unstable solution containing more of the solute than it can permanently hold.
volumetric solution one that contains a specific quantity of solvent per stated unit of volume.

isotonic solution

A solution that has a concentration of electrolytes, nonelectrolytes, or both that will exert osmotic pressure equivalent to that of the solution with which it is being compared. Either 0.16 molar sodium chloride solution (approx. 0.95% salt in water) or 0.3 molar nonelectrolyte solution is approx. isotonic with human red blood cells. Synonym: balanced solution

The integration of productive failure strategy for the buffered and isotonic solutions section of Pharmaceutics I, the focus of this study, followed several steps, aligned with effective strategies for failure-based activities (Tawfik, Rong, & Choi, 2015) for both their pilot and full implementation.
Since administration of a hypertonic should lead to recruitment of extravascular fluids into the vascular compartment, HSS seems likely to produce a more rapid response and marked hemodynamic effects than isotonic solutions (Bleul et al., 2007; Leal et al., 2012) with a small-volume @ 4 mL/kg BW.
The exercise is followed by a series of questions to help students understand the concept of hypotonic, hypertonic, and isotonic solutions. To further explore the concept of tonicity, students may carry out an extension exercise with potato strips and a 20% NaC1 solution to understand how the presence of a cell wall in plants affects their response to a hypertonic solution.
