I have came up with a kickass idea to quickly produce a large amount of relatively safe (pure) oxycodone HCl injection fluid, as long as you have a large number of these specific pills.
Here in Canada we have a 10 mg IR oxycodone HCl tablet called Supeudol. The thing that's so special about these tabs is that they have ONLY 4 inactive ingredients and they are fucking tiny!! even for 10mg tabs so that tells me that they contain a very small amount of the inactive ingredients that they do have. The ingredients are as follows:
dibasic calcium phosphate
I did my homework and none of these excipients are soluble in water! So, When I got a large quantity of these tabs I put 100 in a beaker and then covered them with 15 mL of distilled water. I used 15 mL because the solubility is 1 gram/ 100mg of oxycodone HCl will disoolve in 10 ml of water to create a saturated solution, so I rekoned to use an extra 5 mL just in case and also it made the injection solution more dilute/safe. So after these tablets sat in the water for a while and completely dissolved (it wouldn't hurt to use a glass stir rod) I poured the entire contents of the beaker into a funnel with a filter paper within it thats positioned above another beaker/ ampoule whatever you want to use to store the solution in. So after it drains what you'll have left is filter paper with all the water insoluble excipients and an ampoule filled with 15 mL of filtered oxycodone HCl solution that is probably cleaner then some solutions some people here inject! The strenght will be 66.66mg per cc/mL so be careful!
I posted this to demonstrate how easy it would be to make an injectable solution that can last many uses as long as it is properly sealed from bacteria/microbes! This method can easily be scaled to suit the amount of available tabs and I guess could be used for any tablets as long as they contain NO water soluble excipients so do your homework before trying!
Edit: Evaporating the solution would also reveals to us pretty much completely pure oxycodone HCl powder, although I'm not quit sure yet what use this could be to use other then something to show off to your friends.
