What type of mixture is an elixir?

An elixir is defined as a clear, sweetened hydroalcoholic liquid used for medicinal purposes. In the context of medication formulation, an elixir typically contains a drug dissolved in a solution that includes both alcohol and water. The presence of alcohol in the solvent not only helps to dissolve certain types of medications that may not be soluble in water alone, but it also acts as a preservative and can enhance the stability of the drug.

The correct answer highlights the essential role of the alcohol solvent in elixirs, differentiating them from other types of mixtures, such as tinctures or syrups, where the composition differs regarding the type and proportion of solvents used. Understanding the unique aspects of elixirs is crucial, especially in pharmacology and when preparing patient medication, as the solvent can influence the drug's bioavailability and effectiveness.
