Assuming your drug is water soluble I don't think any rpm (or rather g) can separate it from the drug from the water... There need to be a density difference and unsolubility

Ajit Seshadri

Certain add-on is possible to fix, colloids duly grouped and removed as floater, or settler matters.

If this is evident in pre-process then heavier sludges may be removed by CF separation done @ 5000rpm+

Well wishes
