Dosulepin hydrochlorideProduct ingredient for Dosulepin

Dosulepin (INN, BAN) formerly known as dothiepin (USAN), is a tricyclic antidepressant with anxiolytic properties that is used in several European and South Asian countries, as well as Australia, South Africa, and New Zealand. It is not FDA-approved due to low therpeutic index and significant toxicity in overdose. Dosulepin inhibits the reuptake of biogenic amines, increasing available neurotransmitter levels at the synaptic cleft. The use of dosulepsin is only recommended in patients who are intolerant or unresponsive to alternative antidepressant therapies. Dosulepsin is a thio derivative of Amitriptyline with a similar efficacy to that of Amitriptyline, and also exhibits anticholinergic, antihistamine and central sedative properties ⁸. Its hydrochloride form is a common active ingredient in different drug formulations.
