Local anaesthetics preferentially bind to costs of sildenafil in the inactive state and prevent them from opening again. This is similar to the mechanism of action of some antiepileptic drugs. Moreover, like antiepileptic drugs, local anaesthetics show вuse dependenceв in that they preferentially block neurons that are transmitting impulses at high frequency (as pain sensory neurons do).
