Nitroglycerin for Fissure & Hemorrhoid Pain
Anyone who has ever experienced a hemorrhoid or anal fissure knows how quickly the pain can take over your day. The throbbing. The sharp sting during a bowel movement. The fear of the next bowel movement. It’s a brutal cycle.
That’s why nitroglycerin cream has become such a widely used treatment. Though best known as a heart medication, nitroglycerin has a remarkable ability to reduce anorectal pain and help fissures heal — especially when compounded into a gentle topical cream.
Let’s explore what makes nitroglycerin so effective, what the research shows, and how it fits into Bummed’s Rapid Relief Cream.
Why Nitroglycerin Works: A Simple Explanation for a Not-So-Simple Pain
Anal fissures and hemorrhoids often refuse to heal because the internal anal sphincter becomes overly tight. This clamps down on the tiny blood vessels that deliver oxygen and nutrients to the area.
No blood flow means no healing.
Nitroglycerin interrupts this cycle by acting as a vasodilator, helping the sphincter muscle relax so blood can circulate normally again. With better blood flow comes less pain, less pressure, and a greater ability for the skin to repair itself.
One of the earliest and most referenced clinical trials on nitroglycerin, published in Diseases of the Colon & Rectum, documented how patients using a nitroglycerin ointment experienced dramatic reductions in pain and saw their fissures heal significantly faster. You can read a summary of that research here in this study on nitroglycerin for anal fissures.
This mechanism is why nitroglycerin tends to work not just on symptoms, but on the actual cause of anal fissure pain.
Why Nitroglycerin Is a Breakthrough Treatment
Over-the-counter creams tend to focus on numbing or soothing the skin. Nitroglycerin goes deeper by addressing muscle spasm and blood flow — the root issues that make fissures and painful hemorrhoids so stubborn.
Patients often report:
- Faster healing, thanks to improved circulation
- Significant pain reduction, especially during bowel movements
- Relief from spasms, allowing the area to finally calm down
These effects explain why nitroglycerin is a cornerstone ingredient in Bummed’s Rapid Relief Hemorrhoid & Fissure Rx Cream.
What Makes Rapid Relief Different
Bummed’s Rapid Relief Cream doesn’t rely on nitroglycerin alone. It blends additional soothing and therapeutic ingredients that work together to bring comfort quickly and keep it going.
Here’s how the formula works:
🎯 Lidocaine for fast, targeted numbing within seconds
⏰ Bupivacaine for longer-lasting pain control
⭐ Hydrocortisone to reduce inflammation and swelling
🌱 Aloe and emollients to calm and moisturize irritated skin
Together, these ingredients create a multi-layered effect: immediate relief, sustained comfort, and support for natural healing.
What the Research Says About Nitroglycerin
Clinical evidence consistently shows that nitroglycerin is highly effective for chronic anal fissures and hemorrhoids. In addition to the landmark 1995 study, more recent research reinforces its benefits.
A systematic review summarizing available trials highlights nitroglycerin’s ability to relax the sphincter, increase blood flow, and promote healing in a large percentage of patients. You can explore this data in this overview of topical nitroglycerin for fissures.
The science is clear. When blood flow increases, healing accelerates — and nitroglycerin excels at making that happen.
Who Should (and Should Not) Use Nitroglycerin
Nitroglycerin is powerful and fast-acting, but it’s not perfect for everyone.
People who tend to get migraines or frequent headaches may be more sensitive to nitroglycerin’s vasodilating effects. In those cases, clinicians may recommend:
- Diluting the cream with Aquaphor
- Using a smaller amount
- Switching to a gentler alternative like diltiazem or nifedipine
Nitroglycerin is not considered pregnancy-safe, so it is avoided in pregnant patients.
For those who are expecting, clinicians often turn to diltiazem instead, which has a gentler profile and is widely used off-label.
This is described in pregnancy safety resources such as this summary of calcium channel blocker use in pregnancy.
The Bottom Line
Nitroglycerin is more than a pain reliever, it’s a healing accelerator that addresses the underlying cause of fissure and hemorrhoid discomfort. By improving blood flow, reducing pressure, and alleviating pain, nitroglycerin helps the body heal more efficiently — so you can get back to living comfortably, faster.
