Description
Curator's Comment: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/8447840 | https://www.drugs.com/uk/dosulepin-capsules-25mg-leaflet.html | https://www.ncbi.nlm.nih.gov/pubmed/9408183

cis-Dosulepin is a stereoisomer of Dothiepin (trade name Prothiaden, Dothep, Thaden, and Dopress; Dosulepin (INN, BAN) a tricyclic antidepressant that is used in several European and South Asian countries, as well as Australia, South Africa, and New Zealand. Dosulepin is used for the treatment of the major depressive disorder and neuropathic pain. Dosulepin is only Therapeutic Goods Administration and Medicines and Healthcare products Regulatory Agency approved for the treatment of the major depressive disorder. Dothiepin is not used in the United States. The central action of cis-dosulepin was compared with that of its antidepressant stereoisomer trans-dosulepin, cis-dosulepin exerted weaker anti-reserpine, anti-tetrabenazine, and 3H-5-HT (serotonin) uptake inhibiting actions than trans-dosulepin, but cis-dosulepin's inhibition of 3H-dopamine and 3H-norepinephrine uptake was slightly more potent than that of trans-dosulepin. On the other hand, cis-dosulepin exhibited extremely potent anticholinergic action in oxotremorine induced tremor, isolated ileum and the 3H-quinuclidinyl benzilate binding test. It also showed potent apomorphine enhancing the action and shortened the period of immobility in the forced swimming test in animals.
