Method of action

Method of action

Duloxetine and venlafaxine are both medications that belong to a class of drugs known as serotonin-norepinephrine reuptake inhibitors (SNRIs). These medications work by increasing the levels of the neurotransmitters serotonin and norepinephrine in the brain. Serotonin is involved in regulating mood, while norepinephrine plays a role in controlling emotions and stress responses.

By inhibiting the reuptake of these neurotransmitters, duloxetine and venlafaxine help to restore the balance of chemicals in the brain, which can improve mood, reduce anxiety, and control pain symptoms. This mechanism of action is believed to be responsible for the therapeutic effects of these medications in treating conditions such as depression, anxiety disorders, and chronic pain.
