Ether can be used as a cosolvent in oral administration elixirs.

Explanation:
Using ether as a cosolvent in oral elixirs is not acceptable. Diethyl ether is extremely flammable and volatile, posing serious safety hazards during manufacturing, storage, and dispensing. It can leave residual solvent in the finished product, which is tightly regulated because of toxicity and potential CNS effects. Ether also tends to be immiscible with water or create unstable, multi-phase systems in hydroalcoholic formulations, and it can impart an unpleasant odor or taste. For these reasons, ether is avoided in oral dosage forms, and safer alternatives like ethanol, glycerin, or propylene glycol are used instead.
