Prodrug can be injected or snorted after soaking 5 minutes in white vinegar with pinch of salt, one potassium chloride dietary supplement and a few drops of betadine.
Yep, that was exactly what the FDA said to Kempharm when they requested an abuse deterrent label for their prodrug, Apadaz. If you know of any pro-drug opioids that actually work as intended and are abuse-deterrent, please share.
So by the standards you describe, a drug should be described as having overdose protection if there is no change for the first 7 tabs and a mild reduction in plasma conc if an 8th tab is taken. Got it. Good luck with your investment.
