Sildenafil for Erectile Dysfunction
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine how different formulations of sildenafil, a medication for erectile dysfunction, are absorbed and tolerated when taken with food. Researchers seek to discover if the new liquid versions, Hezkue and Hezkue Turbo, function differently compared to traditional pills and chewables. Healthy men without serious health issues and with normal kidney function may qualify. Participants will help assess the safety of the new formulations and how they compare to existing products. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants a chance to contribute to early-stage development.
Will I have to stop taking my current medications?
You may need to stop taking certain medications before joining the trial. Specifically, you cannot use CYP450 enzyme inhibitors within 14 days, CYP450 enzyme inducers or St. John's Wort within 28 days, or certain heart and blood pressure medications within 14 days of dosing.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
A previous study tested new versions of sildenafil, called Hezkue and Hezkue Turbo, to assess their safety. The study showed that these versions are generally well-tolerated by healthy adult men. The research focused on how the body absorbs these versions and their overall safety.
For existing sildenafil products, long-term studies have shown they are safe and effective for treating erectile dysfunction (ED) in men. These products have been widely used, with well-documented safety for both short- and long-term use.
Regarding the combination of sildenafil with another drug, tadalafil, studies suggest this combination is generally safe. However, this conclusion is based on past research, and individual experiences may vary.
Overall, these treatments are considered safe, but participants should discuss any concerns with their healthcare provider before joining a clinical trial.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments for erectile dysfunction because they introduce innovative formulations of sildenafil. Unlike traditional tablets, the Hezkue formulations offer a liquid form of sildenafil citrate, potentially allowing for faster absorption and quicker onset of action. Additionally, the trial explores the combination of sildenafil with tadalafil in chewable form, which could enhance efficacy and provide a more convenient dosing option. These unique delivery methods could offer significant advantages over standard pill formats, making the treatments potentially more effective and user-friendly.
What evidence suggests that this trial's treatments could be effective for erectile dysfunction?
Research shows that sildenafil effectively treats erectile dysfunction (ED). Studies indicate that about 82% of men using sildenafil can successfully have intercourse, with 75% succeeding most of the time. In this trial, one group of participants will receive Hezkue or Hezkue Turbo, new liquid versions of sildenafil that may be absorbed faster than regular tablets. Early research suggests these liquids might work more quickly. Another group will receive commercially available sildenafil products, including tablets or sildenafil + tadalafil combination chewables. Studies suggest that products combining sildenafil and tadalafil can improve erectile function, especially in severe cases. Overall, sildenafil has a strong history of helping men with ED.16789
