An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [1]
There are no clinical guidelines outlining the use and implementation of opioid rotation. However, this strategy is commonly used for these various situations: pain not controlled by current opioid, pain controlled but in the presence of intolerable adverse events, pain not controlled despite rapid increase in opioid dose, switching to utilize different alternative routes of administration, or ...
This is the list of Schedule II controlled substances in the United States as defined by the Controlled Substances Act. [1] The following findings are required, by section 202 of that Act, for substances to be placed in this schedule:
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.

Tapentadol is a novel opioid that displays high affinity and selectivity for the μ-opioid receptor; In a human liability pharmacology study conducted by the sponsor, it was found that tapentadol displays a high abuse potential similar to hydromorphone , a controlled substance with a similar risk of abuse, misuse and diversion; and
The Drug Addiction Treatment Act of 2000 (DATA 2000), Title XXXV, Section 3502 of the Children's Health Act, permits physicians who meet certain qualifications to treat opioid addiction with Schedule III, IV, and V narcotic medications that have been specifically approved by the Food and Drug Administration for that indication.
Opioid replacement therapy (ORT), also known as opioid substitution therapy (OST) or Medications for Opioid Use Disorder (MOUD), involves replacing an opioid, such as heroin. [ 112 ] [ 113 ] Commonly used drugs for ORT are methadone and buprenorphine/naloxone ( Suboxone ), which are taken under medical supervision. [ 113 ]
Butorphanol exhibits partial agonist and antagonist activity at the μ-opioid receptor, as well as partial agonist activity at the κ-opioid receptor (K i = 2.5 nM; EC 50 = 57 nM; E max = 57%). [ 8 ] [ 9 ] Stimulation of these receptors on central nervous system neurons causes an intracellular inhibition of adenylate cyclase , closing of influx ...
