solvent

Meaning of solvent: A solvent is a liquid capable of dissolving another substance to form a uniform solution, a role relevant in pharmacy, laboratory work, and toxicology.

Definition of solvent

A solvent is a liquid substance capable of dissolving another substance, called a solute, to form a uniform mixture known as a solution. Water is among the most common solvents used in medicine and pharmacy, though other liquids serve as solvents for substances that do not dissolve well in water.

In pharmacy, the choice of solvent used to prepare a medication can affect how the drug is absorbed, stored, and administered. In toxicology and occupational health, certain industrial solvents are relevant because exposure to them, particularly in poorly ventilated settings, can affect the nervous system, skin, or other organs depending on the specific chemical and level of exposure.

The properties of a given solvent, including how readily it evaporates and how well it dissolves particular substances, determine which applications it is best suited for.

Used in a sentence

The patient's occupational history included regular exposure to industrial solvents in a poorly ventilated workspace.

Good to know

Occupational exposure to industrial solvents is evaluated differently from the therapeutic use of a solvent in a medication, since the health effects of a solvent depend heavily on the specific chemical, the route and duration of exposure, and its concentration.
