Patient asks to make ' SPORTFLEX spray ' (indometacine) in a kind of oil form.

It is very difficult to answer your question with numerical values. Only oil is perhaps a bit greasy. I recommend using castor oil 30 to 50% and to loan up to 100% with ethanol. Castor oil is a solvent for indomethacin and is in itself soluble in ethanol. How much indomethacin is soluble in it, I don't know. Other you do not indicate what concentration of indomethacin you desire.
