Hello,

I'd like to get pure spiro out of my aldactone caps. I thought that this might work:

1) Solve my spiro tabs in ethanol (98% or 99%)
[QUESTION: How much ethanol should I use for every 100mg tab of aldactone?)
2) Once solved shake it so that it completely mixes
3) Let it sit in order for the fillers to precipitate
4) Filter the solution using a coffe filter
5) Allow it to evaporate until you have pure spiro powder (heating if necessary to accelerate evaporation)

Do you think I will lose a lot of spiro in the filtering process?
Do you think that the heating might screw spiro?

Thank you.
