An elixir is a sweet liquid used for medical purposes, to be taken orally and intended to cure one's illness.[1] When used as a pharmaceutical preparation, an elixir contains at least one active ingredient designed to be taken orally.
Etymology
The word was introduced in late Middle English, through Latin from the Arabic Шаблон:Lang (Шаблон:Transl), which in turn is the Arabization of the Ancient Greek Шаблон:Lang (Шаблон:Transl) Шаблон:Gloss (from Шаблон:Lang (Шаблон:Transl) Шаблон:Gloss).[1] For centuries, elixir primarily meant an ingredient used in alchemy, either referring to a liquid which purportedly converts lead to gold, or a substance or liquid which is believed to cure all ills and give eternal life.
Types
Non-medicated elixirs
These are used as solvents or vehicles for the preparation of medicated elixirs. Active ingredients are dissolved in a 15–50% by volume solution of ethyl alcohol:
- aromatic elixirs (USP)
- isoalcoholic elixirs (NF)
- compound benzaldehyde elixirs (NF)
Medicated elixirs
These include:
- antihistaminic elixirs used against allergy, such as chlorpheniramine maleate (USP) or diphenhydramine HCl
- sedative and hypnotic elixirs, the former to induce drowsiness, the latter to induce sleep
- pediatric elixirs such as chloral hydrate
- expectorant elixirs used to facilitate productive cough (i.e. cough with sputum), such as terpin hydrate
East Asian vitamin drinks
Daily non-alcoholic non-caffeinated 'vitamin drinks' have been popular in East Asia since the 1950s, with Oronamin from Otsuka Pharmaceutical perhaps the market leader. Packaged in brown light-proof bottles, these drinks have the reputation of being enjoyed by old men and other health-conscious individuals. Counterparts exist in South Korea and China.
Western energy drinks typically have caffeine and are targeted at a younger demographic, with colorful labels and printed claims of increased athletic/daily performance.

Composition
An elixir is a hydro-alcoholic solution of at least one active ingredient. The alcohol is mainly used to:
- Solubilize the active ingredient(s) and some excipients
- Retard the crystallization of sugar
- Preserve the finished product
- Provide a sharpness to the taste
- Aid in masking the unpleasant taste of the active ingredient(s)
- Enhance the flavor.
The lowest alcoholic quantity that will dissolve completely the active ingredient(s) and give a clear solution is generally chosen. High concentrations of alcohol give burning taste to the final product.
An elixir may also contain the following excipients:
- Sugar and/or sugar substitutes like the sugar polyols glycerol and sorbitol.
- Preservatives like parabens and benzoates and antioxidants like butylated hydroxytoluene (BHT) and sodium metabisulfite.
- Buffering agents
- Chelating agents like sodium ethylenediaminetetraacetic acid (EDTA)
- Flavoring agents and flavor enhancers
- Coloring agents
Storage
Elixirs should only be stored in a tightly closed, light resistant container away from direct heat and sunlight.
