Treatment Summary

Alprostadil is a drug naturally produced by the body that causes blood vessels to widen, increasing the amount of blood flowing to certain areas. In infants, it is used to prevent closure of the ductus arteriosus, a blood vessel that helps to provide oxygen and nutrients to the fetus. In adults, it is used to treat erectile dysfunction due to a variety of causes.

Effectiveness

How Alprostadil Affects Patients

Alprostadil (prostaglandin E1) is a natural substance that can widen the blood vessels and increase blood flow. In adults, this leads to increased blood flow in the penis, causing it to become stiff. In infants, it can help increase the amount of blood going to either the lungs or the rest of the body.

How Alprostadil works in the body

Alprostadil increases blood flow in infants in multiple ways. It prevents the closure of a blood vessel connecting the pulmonary artery and aorta, allowing blood to flow through it. It also relaxes the smooth muscle of the corpora cavernosa and cavernosal arteries, allowing more blood to enter the penis and causing it to swell and become rigid. These effects create increased pulmonary or systemic blood flow, increased oxygen supply to tissues, improved renal perfusion and increased systemic blood flow to the lower body.

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

Is alprostadil still available?

"Alprostadil is a medication that is prescribed to men who suffer from erectile dysfunction. It is not available over the counter."

Answered by AI

Where do you inject alprostadil?

"To give the injection, insert the needle into the penis until almost all of the metal part is inside. Do not inject the medicine just under the skin, at the top or head of the penis, or at the base of the penis near the scrotum or testes. Avoid injecting into any blood vessels that you can see."

Answered by AI

What is the side effect of alprostadil?

"Some common side effects of using a penis pump are: mild pain in your penis, urethra, or testicles; redness of the penis; or warmth or burning in your urethra."

Answered by AI

What is the drug alprostadil used for?

"Alprostadil is an injection used to treat erectile dysfunction in males. It is a vasodilator, meaning it increases blood flow by expanding blood vessels. This increased blood flow to the penis causes an erection."

Exparel/Bupivacaine Mixture for Postoperative Pain in Erectile Dysfunction Surgery

18+
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.

Ibuprofen for Patent Ductus Arteriosus

< 18
All Sexes
Hamilton, Canada

Newborns born early are at risk for a serious health problem called patent ductus arteriosus (PDA). PDA is a passageway between heart and lung that can cause life-threatening complications such as bleeding in the brain or even death if it remains open and large. When closure of PDA is needed, doctors make every attempt to do it as soon as possible. Ibuprofen is the best drug to close the PDA, but it only works for 50% of small newborns. The investigators have shown before that small newborns handle ibuprofen differently and the amount of active ibuprofen that reaches their blood can be very unpredictable. Studies have shown if enough ibuprofen reaches the body, it can close the PDA. Therefore the investigators designed this study to see whether it is possible to give each newborn the right amount of ibuprofen that their body needs to close the PDA. The investigators will compare two ways to give ibuprofen in a small number of newborns: 1 - standard amount of ibuprofen to everyone, which is the usual care or 2 - ibuprofen doses that will be changed based on how much active ibuprofen has reached the body and how well the newborn's PDA is closing. The investigators will then compare the number of PDAs closed in each group and closely monitor any possible challenges for this new practice. By doing this project, the goals can be summarized as below: A. Primary goal: To determine if it is feasible to successfully run a larger study in the future. B. Secondary goals 1. To assess how well and how safely the personalized (MIPD) method works, using a tool called WAPPS-PDA to guide dosing. 2. To compare the effectiveness and safety of the personalized method with standard ibuprofen dosing. 3. To identify drug levels in the blood (Cmin, AUC0-24, AUC0-72) that are associated with complete, partial, or no response to treatment.

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.
