U-47700: Difference between revisions

Line 65:

Tolerance to many of the effects of U-47700 [[Time to full tolerance::develops with prolonged and repeated use]]. The rate at which this occurs develops at different rates for different effects, with tolerance to the constipation-inducing effects developing particularly slowly for instance. This results in users having to administer increasingly large doses to achieve the same effects. After that, it takes about [[Time to half tolerance::3 - 7 days]] for the tolerance to be reduced to half and [[Time to zero tolerance::1 - 2 weeks]] to be back at baseline (in the absence of further consumption). U-47700 presents cross-tolerance with [[Cross-tolerance::all other [[opioids]]]], meaning that after the consumption of U-47700 all [[opioid]]s will have a reduced effect.

The risk of fatal opioid overdoses rise sharply after a period of cessation and [[relapse]], largely because of reduced tolerance.<ref>Why Heroin Relapse Often Ends In Death - Lauren F Friedman (Business Insider) | http://www.businessinsider.com.au/philip-seymour-hoffman-overdose-2014-2</ref> To account for this lack of tolerance, it is safer to only dose a fraction of one's usual [[dosage]] if relapsing. It has also been found that the environment one is in can play a role in opioid tolerance. In one scientific study, rats with the same history of heroin administration were significantly more likely to die after receiving their dose in an environment not associated with the drug in contrast to a familiar environment.<ref>Siegel, S., Hinson, R., Krank, M., & McCully, J.
