Oxycodone HCl is the generic form of OxyContin, which has become one of the more frequently abused drugs. OxyContin is a timed-release formulation which provides a stable level of pain relief for 12 hours. When OxyContin is abused, it is generally crushed, then snorted or injected, releasing a dangerous level of oxycodone into the system all at once. Besides this, the additional danger with injecting OxyContin is that the oxycodone is bound in an insoluble matrix of polymers. When injected, this matrix is both a foreign substance which can trigger an inflammatory response, and, since there is a limit to how finely drug abusers grind their pills, a swarm of little chunks let loose into the circulatory system, just custom-made to plug up an arteriole somewhere important (like in the brain..).
