Duratia 90 mg contains Dapoxetine, which is primarily used to treat premature ejaculation (PE) rather than erectile dysfunction (ED). Dapoxetine is a selective serotonin reuptake inhibitor (SSRI), and it works by increasing serotonin levels in the nervous system, which helps delay ejaculation.

Dapoxetine can be used off-label for conditions other than PE because of its SSRI properties. Some potential off-label uses include:

1. Depression and Anxiety: Since Duratia 90 mg is an SSRI, it can potentially help in managing symptoms of depression and anxiety, similar to other SSRIs like fluoxetine or sertraline.
2. Social Anxiety Disorder: The medication might be used to help reduce the symptoms of social anxiety disorder, given its effects on serotonin levels.
3. Generalized Anxiety Disorder (GAD): Duratia 90 mg may help in managing GAD symptoms due to its impact on serotonin reuptake.

It's important to note that using Dapoxetine for off-label purposes should only be done under the supervision of a healthcare provider. They can assess the risks and benefits, monitor for side effects, and ensure that the medication is used safely and effectively for conditions other than its primary indication.
