Sildenafil is an effective treatment for erectile dysfunction in men across various conditions. Careful consideration of risks, benefits, and patient-specific factors is crucial for its prescription.

Area of Science:

  • Pharmacology
  • Urology
  • Cardiology

Background:

  • Sildenafil citrate, approved in 1998, is widely used for erectile dysfunction (ED).
  • Recent research has enhanced understanding of sildenafil's efficacy, safety, contraindications, and drug interactions.
  • Expanded knowledge includes its application in specific patient groups.

Purpose of the Study:

  • To review recent studies on sildenafil's efficacy and safety in treating erectile dysfunction.
  • To examine adverse effects, drug interactions, and socioeconomic factors of sildenafil use.
  • To focus on sildenafil's effectiveness in specific patient populations, including those with prostate cancer, diabetes, heart disease, spinal cord injuries, and neurologic disorders.

Main Methods:

  • Searched MEDLINE, PREMEDLINE, and International Pharmaceutical Abstracts for literature from January 1999 to August 2000.

  • Included clinical studies, case reports, commentaries, and editorials on sildenafil, Viagra, and erectile dysfunction.
  • Focused on identifying efficacy, safety, and interaction data.

    • Main Results:

    • Sildenafil is effective for ED in men with conditions like diabetes, neurologic disorders, and post-prostatectomy/radiation.
    • It shows limited efficacy in women, except for SSRI-associated sexual dysfunction.
    • Sildenafil has an acceptable safety profile, but risks exist for patients with cardiovascular disease or those on nitrates. Drug interactions with CYP3A4 inhibitors can increase toxicity.

    Conclusions:

    • Sildenafil is a highly effective first-line therapy for male erectile dysfunction.
    • Prescribing decisions should weigh cost-benefit, patient access, and insurance coverage.
    • Further research and clinical judgment are essential for optimal patient management.
