Dimetacrine is primarily used as an antidepressant in the treatment of mood disorders. It works by inhibiting the reuptake of neurotransmitters like norepinephrine and serotonin, helping to balance mood and alleviate symptoms of depression. Additionally, it has been explored for its potential in managing anxiety and other related mental health conditions. Due to its pharmacological properties, it is often prescribed when other antidepressant treatments have not been effective. However, its use is carefully monitored due to potential side effects and interactions with other medications.
