Methadone 11-20 immunoglobulin lambda variable 2-18 Homo sapiens 93-101 24117196-3 2014 Considering the common assumption that an inhibition of the cardiac Na+ channel Na(v)1.5, is the primary mechanism for local anaesthetic (LA)-induced cardiotoxicity, we hypothesized that methadone has LA-like properties leading to a modulation of Na(v)1.5 channels. Methadone 187-196 immunoglobulin lambda variable 2-18 Homo sapiens 80-88 24117196-3 2014 Considering the common assumption that an inhibition of the cardiac Na+ channel Na(v)1.5, is the primary mechanism for local anaesthetic (LA)-induced cardiotoxicity, we hypothesized that methadone has LA-like properties leading to a modulation of Na(v)1.5 channels. Methadone 187-196 immunoglobulin lambda variable 2-18 Homo sapiens 247-255 24117196-4 2014 EXPERIMENTAL APPROACH: The whole-cell patch clamp technique was applied to investigate the effects of methadone on wild-type and mutant human Na(v)1.5 channels expressed in HEK293 cells. Methadone 102-111 immunoglobulin lambda variable 2-18 Homo sapiens 142-150 24117196-6 2014 KEY RESULTS: Methadone inhibited Na(v)1.5 channels in a state-dependent manner, that is, tonic block was stronger with inactivated channels than with resting channels and a use-dependent block at 10 Hz. Methadone 13-22 immunoglobulin lambda variable 2-18 Homo sapiens 33-41 24117196-10 2014 CONCLUSIONS AND IMPLICATIONS: Methadone interacted with the LA-binding site to inhibit Na(v)1.5 channels.
