Description

Caramiphen is a muscarinic M1 acetylcholine receptor antagonist, which was used for the treatment of Parkinson Disease and cough, but then there using were discontinued. Caramiphen is also used in local anesthesia, and effect could be achieved through the suppression of voltage-gated Na⁺ currents.

It was investigated the effect of caramiphen (300uM) on voltage-gated sodium channels in differentiated neuronal NG108-15 cells. Caramiphen exhibited a milder state-dependence of block (IC₅₀ of 52.1 and 99.5 µM at holding potentials of -70 and -100 mV, respectively).
