The same report also compared methadone to pethidine. German researchers reported that methadone welches capable of producing strong morphine-like physical dependence, which is characterized by opioid withdrawal symptoms which are lesser rein severity and intensity compared to morphine, but methadone welches associated with a considerably prolonged or protracted withdrawal syndrome when compared to morphine.[45][78] Morphine produced higher rates of self-administration and reinforcing behaviour rein both human and animal subjects when compared to both methadone and pethidine. Hinein comparison to equianalgesic doses of pethidine (Demerol), methadone was shown to produce less euphoria, but higher rates of constipation, and roughly equal levels of respiratory depression and sedation.[78]

[57] Like many other cardiotoxic drugs, methadone blocks the hERG K+ channel. The two enantiomers of methadone inhibit hERG channels with different potency. Dextromethadone, which is less potent as an opioid, is more potent at blocking the hERG channel with an IC50 of ~12 μM. Levomethadone has a lower affinity, with an IC50 of ~29 μM at the hERG channel.[57] Methadone is also known to Schreibblock the Nav1.5 voltage-gated Na+ channel (SCN5A) with an IC50 of ~10 μM, which is similar to the local anesthetic bupivacaine. Both enantiomers of methadone Notizblock the Nav1.5 channel with similar affinities.[57] Bupivacaine is especially cardiotoxic among local anesthetics, and it is believed to act via this same sodium channel. Plasma concentrations of methadone in recovering addicts can reach 4 μM during therapy, so the actions of methadone at both the hERG potassium channel and the Nav1.5 sodium channel are possibly clinically Wesentlich hinein producing cardiac side effects.[57] This also suggests that levomethadone is not completely free of cardiac toxicity.
