Acute use (1–3 days) yields a potency about 1.5× stronger than that of morphine and chronic use (7 days+) yields a potency about 2.5 to 5× that of morphine. Similarly, the effect of tramadol increases after consecutive dosing due to the accumulation of its active metabolite and an increase of the oral bioavailability in chronic use.
After a dose of conventional (immediate-release) oral oxycodone, the onset of action is 10 to 30 minutes, [10] [8] and peak plasma levels of the drug are attained within roughly 30 to 60 minutes; [10] [8] [73] in contrast, after a dose of OxyContin (an oral controlled-release formulation), peak plasma levels of oxycodone occur in about three ...
Oxymorphone (sold under the brand names Numorphan and Opana among others) is a highly potent opioid analgesic indicated for treatment of severe pain. Pain relief after injection begins after about 5–10 minutes, after oral administration it begins after about 30 minutes, and lasts about 3–4 hours for immediate-release tablets and 12 hours for extended-release tablets.

The age-adjusted drug poisoning death rate involving heroin doubled from 0.7 to 1.4 deaths per 100,000 people between 1999 and 2011 and then continued to increase to 4.1 in 2015. [192] The third wave of overdose deaths began in 2013, related to synthetic opioids, particularly illicitly produced fentanyl. [ 190 ]
Oxycodone/naloxone was released in 2014 in the United States, [5] in 2006 in Germany, and has been available in some other European countries since 2009. In the United Kingdom, the 10 mg oxycodone / 5 mg naloxone and 20 mg / 10 mg strengths were approved in December 2008, and the 40 mg / 20 mg and 5 mg / 10 mg strengths received approval in ...
The manufacturers in the UK claim it is twice as potent as morphine, but in reality studies show a range, with an average of 1.5, ie oxycodone is 1.5 - 2 times as potent as morphine. Diacetylmorphine (heroin) is slightly more potent than morphine, but the difference is small and it is likely that oxycodone is a little more potent than ...
