Tinctures are...

• A. Alcoholic preparations of a soluble drug, usually from plant source; may contain water.
• B. Aqueous solutions of insoluble solids.
• C. Solid dosage forms for topical use.
• D. Gaseous preparations for inhalation.

Answer: (A)

Tinctures are alcoholic extracts. They are liquid preparations created by extracting a drug, usually plant material, with alcohol (ethanol) or a hydroalcoholic solvent. The active constituents must be soluble in the alcohol, and water may be present in the final product to aid extraction or dissolve some components. This makes tinctures distinct from other forms: they are not aqueous suspensions of insoluble solids, not solid dosage forms for topical use like creams, and not gaseous inhalation products. Examples include plant-derived tinctures where the plant material has been macerated or percolated in alcohol to yield a concentrated liquid extract.
