Duratia 90 mg is not a sildenafil (ED) medication. It does not treat erectile dysfunction the way drugs like sildenafil do. Instead:  What Duratia 90 mg actually is It is a prescription medicine whose active ingredient is dapoxetine — not sildenafil. Dapoxetine belongs to a class called selective serotonin reuptake inhibitors (SSRIs).   What Duratia is used for Duratia 90 mg is used to treat premature ***** (PE) in men. It helps increase the time to ***** and control over *****, but it does not improve erections or treat erectile dysfunction.   How it works Dapoxetine boosts serotonin levels in the brain, which can delay the ejaculatory reflex — helping men last longer during *****.  Not for Erectile Dysfunction Erectile dysfunction (ED) medications such as sildenafil, tadalafil, or vardenafil work differently: they increase blood flow to the ***** to help achieve and maintain an erection. Duratia (dapoxetine) does not have this effect and will not help if the main issue is difficulty getting or keeping an erection.   When a doctor may prescribe it A healthcare provider may suggest Duratia if premature ***** is diagnosed as the main concern. If erectile difficulties are present, your doctor might choose a different class of medicine (e.g., sildenafil or tadalafil). Always consult a doctor before starting or combining treatments.
