Erectile dysfunction (ED) is a common condition affecting men, often linked to aging and multifactorial causes. Oral sildenafil offers a promising, effective, and well-tolerated treatment option for men with ED.

Area of Science:

  • Urology
  • Andrology
  • Pharmacology

Background:

  • Erectile dysfunction (ED) is a prevalent condition impacting men's quality of life, with prevalence increasing with age.
  • ED is multifactorial, stemming from organic and/or psychological causes, including impaired nitric oxide production.
  • Current treatments like intracavernous injections have limited patient acceptance.

Purpose of the Study:

  • To review the pathophysiology of ED and discuss emerging therapeutic strategies.
  • To highlight the efficacy and tolerability of new oral agents for ED treatment.
  • To evaluate sildenafil as a promising treatment for ED.

Main Methods:

  • Review of recent advances in understanding ED pathophysiology.
  • Analysis of available and emerging therapeutic options for ED.

  • Focus on the mechanism of action and clinical application of oral sildenafil.

    • Main Results:

    • Nitric oxide deficiency is a key factor in ED.
    • Oral agents like sildenafil and intraurethral prostaglandin-E1 improve treatment acceptability.
    • Sildenafil, a phosphodiesterase type-5 inhibitor, effectively increases penile response to sexual stimulation.

    Conclusions:

    • Oral sildenafil (25-100 mg) is an effective and well-tolerated treatment for ED of unknown etiology.
    • Newer oral and intraurethral therapies enhance patient acceptance for ED management.
    • Addressing underlying endocrine disorders is crucial for specific ED cases.
