Treatment Summary

Tadalafil is a medication used to treat erectile dysfunction, pulmonary arterial hypertension, and enlarged prostate. It was approved by the FDA in 2003 for erectile dysfunction and 2009 for pulmonary arterial hypertension. Tadalafil is more selective than other similar drugs, such as sildenafil, and has a longer half-life which makes it suitable for chronic daily dosing in the treatment of pulmonary arterial hypertension.

Effectiveness

How Tadalafil Affects Patients

Tadalafil helps treat erectile dysfunction by increasing blood flow to the penis. It also helps reduce blood pressure in the blood vessels of the lungs for people with PAH and may help reduce the size of the prostate and related urinary symptoms in people with BPH. It is less likely to cause visual side effects than other drugs that help treat ED.

How Tadalafil works in the body

Tadalafil is an effective drug for treating erectile dysfunction, pulmonary arterial hypertension, and benign prostatic hyperplasia. It works by increasing the signaling of nitric oxide and cyclic guanosine monophosphate (cGMP) in the body. This signaling relaxes smooth muscle cells, allowing blood to flow more freely and produce an erection. In pulmonary arterial hypertension, tadalafil relaxes the muscles of the arteries, reducing pressure and easing symptoms. In benign prostatic hyperplasia, it reduces inflammation and tissue remodeling, which can help improve urinary flow. Tadalafil has a

Tadalafil for Inability to have an Erection

For a tiny weekly price, I've been getting more erections than ever before. It's fantastic to feel healthy and happy again. If you're considering this treatment, I say go for it!

Tadalafil for Inability to have an Erection

I'm so glad that Johnny Depp is the new face of Tadalafil / Cialis. It's great that somebody with such a high profile is willing to talk about ED openly. I hope this helps normalize the conversation around erectile dysfunction and lets people know that there are treatments available.

Tadalafil for Inability to have an Erection

This drug has been helping me for a while now. It's the best because it doesn't cause headaches like other drugs do. Once I took it, I remained hard for up to four days. I've even recommended it to friends—it really is the best.

Tadalafil for Enlarged Prostate

I took 5mg daily for BPH but stopped after a week because the severe back and leg pain, calf tightness, and reflux at night were too many side effects. It worked to address the mild symptoms I had but at too high of a cost.

Tadalafil for Inability to have an Erection

I would not recommend this product to anyone. I was taking 10 mg before they boosted it up to 20 mg because it wasn't working properly and let me tell you, this is the worst medicine I have ever taken for treatment. It caused me more pain than anything in my joints, muscles, back, legs, shoulders - everywhere. They should really take this off the market; it's not worth the price or the pain.

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

How long does tadalafil last after taking?

"Tadalafil lasts for up to 36 hours, which is longer than other PDE5 inhibitors."

Answered by AI

What happens after taking tadalafil?

"By controlling the enzyme, tadalafil helps to maintain an erection by increasing blood flow to the penis after the penis is stroked. Without physical action to the penis, such as that occurring during sexual intercourse, tadalafil will not work to cause an erection."

Answered by AI

What are the dangers of tadalafil?

"The following symptoms may be experienced: arm, back, or jaw pain; chest pain, discomfort, tightness, or heaviness; cold sweats; faintness or lightheadedness when getting up suddenly from a lying or sitting position; fast or irregular heartbeat; increased erection; pain or discomfort in the arms, jaw, back, or neck; pounding in the ears."

What does tadalafil do for a man?

"Tadalafil is a prescription medication used to treat erectile dysfunction, enlarged prostate, and high blood pressure in the lungs."

Exparel/Bupivacaine Mixture for Postoperative Pain in Erectile Dysfunction Surgery

Male
Winston-Salem, NC

The inflatable penile prosthesis (IPP) is the gold standard for surgical management of erectile dysfunction (ED) and there is no consensus on the best postoperative pain management regimen. In the wake of the opioid epidemic, postoperative pain management is heavily scrutinized. The National Institute of Health estimated over 81,000 individuals died following overdose of any opioids in 2022 alone; of these, over 14,000 deaths were linked to prescription opioids. Thus, strategies to minimize postoperative pain should not only improve patient experience but also lessen the need to escalate to opioid usage.

SAFE Technique for Erectile Dysfunction

18+
Male
New York, NY

Robotic-assisted radical prostatectomy (RALP) has become the standard of care in the management of localized prostate cancer. However, post-prostatectomy erectile dysfunction (ED) and urinary incontinence still pose a challenge that adversely affects the patient's quality of life. Hydrodissection (HD) was introduced in 1987 in the medical field and it was tested for the first time during a retropubic radical prostatectomy back in 2005. Since then, research has indicated an improvement in erectile function results, presumably because of a less traumatic neural dissection and a decreased risk of neuropraxia. In an effort to achieve a balance between oncological excision and functional preservation, prostate surgery is evolving to incorporate intraoperative real-time evaluation of extracapsular extension. Recently, a micro-ultrasound operating at 29 MHz has been introduced. It provides a resolution down to 70 μ to assess the glandular pattern and cellular density of the prostatic tissue. Given the experience in more than a thousand cases with this technology, and the growing literature showing promising results in the detection and staging of prostate cancer; the researchers decided to implement this tool as guidance for hydrodissection of the layers of the lateral prostatic fascia. Robotic-Assisted Laparoscopic Prostatectomy and SAFE (Saline assisted fascial engorgement) nerve preservation guided by Microultrasound (MUS) is a prospective randomized controlled trial designed to evaluate the impact of normal saline solution hydrodissection (HD) on erectile function outcomes after RALP. This innovative approach consists of a transrectal ultrasound-guided HD using a high-resolution Microultrasound (MUS) (ExactVu micro-ultrasound, Exact Imaging, Markham, Canada). The technique will be applied to those patients who undergo grade 1, 2, or 3 NS approach taking into account the grading system proposed by Tewari et al. The hypothesis is that the SAFE technique could minimize the risk of a traumatic neurovascular bundle dissection while assessing the prostatic capsule integrity with a high-resolution MUS. The researchers also hypothesize that the use of SAFE along with RALP will optimize the post-surgery recovery of erectile function.

Optilume vs Rezum for Enlarged Prostate

18+
Male
Montréal, Canada

Lower urinary symptoms (LUTS) affect older men and their frequency and severity increase with age. According to Berry et al., the histological diagnosis of benign prostatic hyperplasia (BPH) increases from 25% in the group age between 40 to 49 years to 80% in the group age between 70 to 79 years (1). However, this hyperplasia can lead to a bladder outlet obstruction (BOO) secondary to benign prostatic enlargement (BPE), causing storage and voiding symptoms, associated with a considerable impairment of the quality of life (2). Surgical therapy of BPH has continuously evolved in recent years. The current gold standard for the endoscopic treatment of BPH is the transurethral resection of the prostate (TURP). Other innovative techniques were developed including Urolift, transurethral laser enucleation (holmium, thulium) and Aquablation therapy. One of the latest technologies for the management of BPH are Optilume BPH Catheter System (Optilume®, Urotronic Inc, Minneapolis, USA) and Rezum Water Vapor Therapy (Rezum System, Bostocn Scientific, Marlborough, MA). The purpose of the present study is to compare between patient experience, symptom relief and functional improvement when using the Optilume BPH Catheter System (Optilume®, Urotronic Inc, Minneapolis, USA) and Rezum Water Vapor Therapy (Rezum System, Boston Scientific, Marlborough, MA).
