Duratia 90 mg (which contains dapoxetine) is specifically designed to treat premature ejaculation (PE), rather than erectile dysfunction (ED). While it helps men with PE by delaying ejaculation and improving control during sexual activity, it does not directly address the underlying causes of ED.
If ED is related to relationship issues, such as stress, anxiety, or emotional factors, the effectiveness of Duratia 90 mg may be limited in terms of improving erectile function. However, addressing relationship issues is a crucial component in managing ED. Here's how Duratia might still be relevant:

1. Psychological Factors: Relationship issues can contribute to both ED and PE. If anxiety or stress about sexual performance is contributing to premature ejaculation, Duratia may help by improving control over ejaculation, potentially reducing performance anxiety in the short term. This may, in turn, improve the overall sexual experience and help with confidence.
   
2. Combination Therapy: If ED is also present alongside PE, a treatment plan that addresses both conditions may be more effective. Medications like sildenafil (Viagra) or tadalafil (Cialis) could be used to treat ED, while Duratia targets premature ejaculation. However, it’s important to consult with a healthcare provider to determine the best approach.
   
3. Communication and Counseling: In many cases, relationship issues contributing to ED can be helped with open communication, therapy, or counseling. A mental health professional or sex therapist could help address the emotional or psychological factors causing sexual dysfunction, improving both ED and PE.
   

While Duratia 90 mg may not directly treat erectile dysfunction related to relationship issues, it can be helpful for premature ejaculation that may coexist with ED. For comprehensive treatment, discussing both issues with a doctor and exploring appropriate therapies would be beneficial.
