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]
The therapeutic index (TI; also referred to as therapeutic ratio) is a quantitative measurement of the relative safety of a drug with regard to risk of overdose.It is a comparison of the amount of a therapeutic agent that causes toxicity to the amount that causes the therapeutic effect. [1]
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
For the first time in two decades, the Food and Drug Administration (FDA) has approved a new class of medication that provides an alternative to addictive opioids for patients looking to manage ...
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 ...
Studies in more than 870 patients with acute pain due to foot and abdominal surgeries showed Vertex's drug provided more relief than a dummy pill but didn't outperform a common opioid ...
However, since opioid antagonists also block the beneficial effects of opioid analgesics, they are generally useful only for treating overdose, with use of opioid antagonists alongside opioid analgesics to reduce side effects, requiring careful dose titration and often being poorly effective at doses low enough to allow analgesia to be maintained.
Cessation of dosing with morphine creates the prototypical opioid withdrawal syndrome, which, unlike that of barbiturates, benzodiazepines, alcohol, or sedative-hypnotics, is not fatal by itself in otherwise healthy people. Acute morphine withdrawal, along with that of any other opioid, proceeds through a number of stages.
