Minaprine dihydrochloride is primarily used in the treatment of depressive disorders. It functions as an antidepressant by influencing the levels of certain neurotransmitters in the brain, particularly serotonin and dopamine, which play a key role in mood regulation. This helps alleviate symptoms of depression such as persistent sadness, lack of energy, and loss of interest in daily activities. Additionally, it has been studied for its potential neuroprotective effects, which could be beneficial in conditions involving neurodegeneration. Its application is typically under medical supervision to ensure appropriate dosing and to monitor for any side effects.
