Dexamethasone is poorly water-soluble. its solubility could be improved by using a co-solvent, such as ethanol. to minimise the ethanol content in an oral formulation, optimal water/ethanol mixtures should be used. dexamethasone elixir usp contains 5.00% of ethanol. calculate the solubility parameter of the mixed solvent in this formulation.
how to solve this?
