The abbreviation 'elix.' corresponds to which term?

• A. Litre
• B. Elixir
• C. Compound
• D. Microgram

Answer: (B)

Elix. denotes a medicinal liquid dosage form called an elixir. An elixir is a sweetened hydroalcoholic solution intended for oral use; the alcohol helps dissolve certain drugs and acts as a preservative, while the added sugar and flavoring make it palatable. This specific dosage form distinction is why elix. is the correct term. The other options are not dosage forms: litre is a unit of volume, microgram is a unit of mass, and compound is a general term for a chemical substance, not a presentation for administration.
