Other cotherapies were taken by 26 patients: Selective Serotonin Reuptake Inhibitors (SSRIs) antidepressants (n = 10); immunosuppressive drugs (azathioprine, n = 7); antihypertensives (beta blocking agents and calcium antagonists, n = 7); drugs used for neuropathic pain (gabapentin, n = 2 and pregabalin, n = 1) and trigeminal neuralgia (carbamazepine, n = 2); mood stabilizers (sodium valproate, n = 1); antiparkinsonian drugs (n = 4); muscle relaxant drugs (n = 4); and non-selective blocker of several voltage-sensitive potassium channels (4-aminopyridine, n = 6). This evidence concerns the gene KCND2 and trigeminal neuralgia.
