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]
Hydrocodone is a highly selective full agonist of the μ-opioid receptor (MOR). [28] [54] [49] This is the main biological target of the endogenous opioid neuropeptide β-endorphin. [55] Hydrocodone has low affinity for the δ-opioid receptor (DOR) and the κ-opioid receptor (KOR), where it is an agonist similarly. [49]
The CDC Opioid Guidelines Calculator estimates a conversation rate of 50mg of tapentadol equaling 10 mg of oral oxycodone in terms of opioid receptor activation. [ 18 ] Common side effects include euphoria , constipation , nausea , vomiting , headaches, loss of appetite , drowsiness , dizziness , itching , dry mouth , and sweating . [ 19 ]

Vertex began researching the drug in the 2000s when overdoses were rocketing upward, principally driven by mass prescribing of opioid painkillers for common ailments like arthritis and back pain.
Morphine pharmaceuticals are subject to annual manufacturing quotas; in 2017 these quotas were 35.0 tonnes of production for sale, and 27.3 tonnes of production as an intermediate, or chemical precursor, for conversion into other drugs. [154] Morphine produced for use in extremely dilute formulations is excluded from the manufacturing quota.
According to a Cochrane review in 2013, extended-release morphine as an opioid replacement therapy for people with heroin addiction or dependence confers a possible reduction of opioid use and with fewer depressive symptoms but overall more adverse effects when compared to other forms of long-acting opioids. The length of time in treatment was ...
Most studies suggest that the majority (perhaps as much as 90%) of chronic opioid users develop hypogonadism. A 2015 systematic review and meta-analysis found that opioid therapy suppressed testosterone levels in men by about 165 ng/dL (5.7 nmol/L) on average, which was a reduction in testosterone level of almost 50%.
