Levomethadone provides a lower affinity, with an IC50 of ~29 μM in the hERG channel.[sixty one] Methadone is additionally acknowledged to block the Nav1.5 voltage-gated Na+ channel (SCN5A) with an IC50 of ~10 μM, which is analogous into the neighborhood anesthetic bupivacaine.

Plasma concentrations of methadone in recovering addicts can achieve four μM during therapy, Hence the actions of methadone at equally the hERG potassium channel plus the Nav1.five sodium channel are maybe clinically related in making cardiac side effects.[61] This also suggests that levomethadone just isn't totally free of cardiac toxicity.
