Mean recovery of alcohol from the synthetic elixir was 98.6%. Determination of alcohol Concentration Elixirs usually contain 5-40% alcohol. Patients should be warned against taking any preparations which contain alcohol. To prepare an elixir, the optimal concentration of alcohol is approximately A. The plants have been carefully chosen to create effects similar to alcohol, helping you to relax and unwind, but with none of the negative downsides or after-effects. The alcoholic contents in elixir vary from 5% to 40%. In addition to active drug, they usually contain flavouring and colouring agents to improve patient acceptance. Determination of alcohol:The alcohol concentration in elixir is in range of 5-40% and it is determined using HPLC or UV spectrophotometer. The mean coefficient of variation for alcohol for all samples analyzed was less than 1.4%. Small amounts of alcohol may trigger an alcoholic relapse.

Content uniformity test: Same as in syrup. Phenobarbital Elixir - Clinical Pharmacology. Register, Oxford University Press is a department of the University of Oxford. Identification tests for dexamethasone by thin-layer chromatography, infrared spectroscopy, and relative LC retention times, as well as the gas chromatographic determination of alcohol in the elixirs were also collaboratively studied. Don't already have an Oxford Academic account? All Right Reserved. A normal phase liquid chromatographic method for the determination of dexamethasone in bulk drugs and elixirs was collaboratively studied by 6 laboratories. The proportion of alcohol in elixirs varies widely because the individual components of the elixirs have different water and alcohol solubility characteristics. Aqueous and alcoholic elixirs versus aromatic elixirs † Clyde M. Snow. At a mean concentration … Identification tests for dexamethasone by thin-layer chromatography, infrared spectroscopy, and relative LC retention times, as well as the gas chromatographic determination of alcohol in the elixirs were also collaboratively studied.
