Mianserin

Mianserin is an atypical antidepressant medication used primarily to treat depressive disorders. It works by balancing chemicals in the brain that influence mood and emotional state. Mianserin may also be used off-label for conditions like anxiety and insomnia, particularly in older adults due to its sedative properties.

Uses of Mianserin

• Treatment of major depressive disorder
• Management of depressive symptoms in anxiety disorders
• Off-label use in insomnia and chronic pain management

How it works

Mianserin acts by blocking alpha-2 adrenergic receptors and certain serotonin receptors (5-HT2), increasing the release of norepinephrine and serotonin in the brain. These neurotransmitters help regulate mood and emotional stability.

Benefits
