But the drug itself dissolves pretty well in ethanol and a little acetone.
From a patent:
“Surprisingly, the roxithromycin solubility in methanol is low in comparison to other common alcohols, namely ethanol and isopropyl alcohol, or even to other common organic solvents such as acetone.”
Your combination of ethanol and PPG should do well IMHO. What you are seeing is probably the filler.
