This invention relates to a liquid preparation containing a solution, which has a water content of from 10 to 80%, and an active ingredient coated with a coating material comprising a water-soluble cellulose derivative. The liquid preparation can stably retain the water-unstable active ingredient in it and at the same time, can mask its unpleasant taste and/or smell, and is usable as drug, quasi-drug, cosmetic, food or the like. |
