Elixirs acquiring higher share of Liquor have to have sweetening agent apart from sucrose because sucrose is a little soluble.
Both equally phases with the planning may possibly independent but are quickly mixed by shaking. The preparing is entirely stable to present a homogeneous dose when taken just after suitable shaking.
