[7] Typically, long-term use is only recommended for pain due to cancer. [9] It may be used by mouth or by injection into a vein, muscle, or under the skin. [7]
Steady state is reached after about 5 × 12 = 60 hours. Pharmacokinetics (from Ancient Greek pharmakon "drug" and kinetikos "moving, putting in motion"; see chemical kinetics ), sometimes abbreviated as PK , is a branch of pharmacology dedicated to describing how the body affects a specific substance after administration.

Opioid-induced hyperalgesia (OIH) or opioid-induced abnormal pain sensitivity, also called paradoxical hyperalgesia, is an uncommon condition of generalized pain caused by the long-term use of high dosages of opioids [1] such as morphine, [2] oxycodone, [3] and methadone. [4] [5] OIH is not necessarily confined to the original affected site. [6]
The withdrawal symptoms associated with morphine addiction are usually experienced shortly before the time of the next scheduled dose, sometimes within as early as a few hours (usually 6 h to 12 h) after the last administration.

Based on a human abuse liability study, 50 mg of tapentadol produces comparable opioid effects to that of 4 mg of hydromorphone. Since 2009 the drug has been categorized in the US as a Schedule II Controlled Substance with ACSCN 9780; in 2014 it was allocated a 17,500 kg aggregate manufacturing quota.
This study also stated that this rate varied by region, agreeing with prior studies. [29] In 2024, a study evaluated the early results of the 2020 American Academy of Pediatrics guidelines for managing neonatal opioid withdrawal symptoms. [47] These guidelines proposed using non-pharmacological approaches as first line treatment. [29]
