Dothiepin (Dosulepin; Dothep) is an antidepressant agent with sedative/anxiolytic activity. Dothiepin is an inhibitor preferring of noradrenaline uptake than serotonin uptake. Dothiepin facilitates noradrenergic neurotransmission via inhibiting the neuronal uptake. Dothiepin is also an antagonist of histamine H1-receptor without cardiotoxicity. Dothiepin exhibits significant analgesic activity in psychogenic facial pain，idiopathic fibromyalgia syndrome or rheumatoid arthritis[1].
