metapramine profile

Metapramine is a tricyclic antidepressant (TCA) with a chemical structure similar to imipramine. It was synthesized in the 1960s and was initially marketed as an antidepressant. It is believed to exert its antidepressant effects by inhibiting the reuptake of serotonin and norepinephrine in the brain. However, metapramine has been found to have significant side effects, including anticholinergic effects, sedation, and cardiovascular problems. Consequently, its use as an antidepressant has largely been discontinued. Some studies have investigated its potential use in treating other conditions, such as chronic pain and anxiety disorders, but further research is needed. Metapramine continues to be studied due to its unique chemical structure and its potential for therapeutic applications in specific patient populations. It is also used in the synthesis of other tricyclic antidepressants.'
