- Duloxetine could be a potent inhibitor of neuronal serotonin and norepinephrine reuptake and a less potent inhibitor of dopamine reuptake. Duloxetine has no significant affinity for dopaminergic, adrenergic, cholinergic, histaminergic, opioid, glutamate, and GABA receptors. The antidepressant drug and pain inhibitory actions of duloxetine are believed to be associated with its potentiation of serotonergic and noradrenergic activity within the central nervous system. The mechanism of action of duloxetine in SUI has not been determined, however, is believed to be related to the potentiation of serotonin and norepinephrine activity within the spinal cord, that will increase urethral closure forces and thereby reduces involuntary urine loss.

- The suggested dose for treating depression is 20 or 30 mg twice daily or 60 mg once daily. Patients are also started with 30 mg once daily for one week before the dose is advanced to 60 mg daily.The suggested dose for anxiety disorder, pain associated with diabetic neuropathy, fibromyalgia, or chronic musculoskeletal pain is 60 mg daily. starting at 30 mg daily for one week before increasing to sixty mg daily might facilitate patients comply with the drug. there’s no proof that doses larger than 60 mg/day provide further advantages.
