Amineptine hydrochloride is primarily used as an antidepressant, particularly in the treatment of major depressive disorder. It functions by enhancing the release of dopamine and inhibiting its reuptake, which helps improve mood and alleviate symptoms of depression. Due to its stimulating properties, it has also been prescribed to address fatigue and lack of energy often associated with depressive states. However, its use has been restricted or discontinued in many countries due to concerns about potential abuse and adverse effects, such as hepatotoxicity. In clinical settings, it was valued for its rapid onset of action compared to other antidepressants, making it effective for short-term relief in certain cases.
