It belongs to the group of medicines known as tricyclic antidepressants or “mood elevators.” Tricyclic antidepressants block the passage of stimulant chemicals norepinephrine and/or serotonin – in and out of nerve endings, producing a tranquillizing or sedative effect. They also counteract the effects of the neurotransmitter acetylcholine.
Such medicines work by causing long-term changes in the way nerve endings release specific neurotransmitters, that are responsible for the transmission of nerve signals. Tricyclic antidepressants can elevate mood, increase physical activity and mental alertness, and improve appetite and sleep patterns after 2-4 weeks of use.
The medicine is prescribed for:
• Relieve of mental depression

The medication gradually relieves, but does not cure, symptoms of depression.
