What is Zelnorm
TegaserodThe Generic name of this drug
Treatment SummaryZelnorm is a medication developed by Novartis that was first approved by the FDA in 2002 to treat irritable bowel syndrome with constipation (IBS-C). In 2007, due to concerns of potential cardiovascular risks, the drug was removed from the US market, but was re-approved in 2019 for female patients under 65 who are at a lower risk of a cardiovascular event. Zelnorm works by targeting serotonin-4 (5-HT(4)) receptors in the gut wall and smooth muscle cells to help with esophageal relaxation, peristaltic gut movement, and natural secretions. However, it is still not

Effectiveness
How Zelnorm Affects PatientsTegaserod works by activating serotonin type-4 (5-HT(4)) receptors and blocking 5-HT(2B) receptors. It has no effect on 5-HT(1), 5-HT(3) or dopamine receptors. In clinical studies, the drug did not cause a dangerous increase in heart rate, though it did lead to an increase of up to 60 milliseconds in 7% of patients. The same studies showed that tegaserod and its main metabolite could increase platelet aggregation in laboratory tests, but it is unclear what this means for people taking the drug.
How Zelnorm works in the bodyIrritable bowel syndrome (IBS) is a condition that causes abdominal pain, bloating, and other uncomfortable issues with the digestive system. One potential way to treat IBS-C (constipation-predominant IBS) is through 5-hydroxytryptamine (5-HT or serotonin). 5-HT can cause the release of chemicals in the gut that help move material through it, as well as relax the esophagus and reduce muscle contraction in the colon. It also helps to create natural fluid secretion in the gut. Tegaserod is a medication that works by activating 5-HT(4) receptors

Zelnorm Reviews: What are patients saying about Zelnorm?

12/1/2010 This treatment is really effective for those suffering from IBS. It helped me a lot and I only take it now when I have a flare up. The FDA made a mistake by making this unavailable to people.

6/20/2011 This drug is the only one that has ever kept me free of obstruction, pain, and hospitalization. I was told 4 years ago that it had been taken off the market and I have had another severe attack again, severe pain, distention , projectile vomiting.
5Patient Review
1/8/2011 This medication was a complete game-changer for me when I first took it. I had no idea that I was constipated before, and this drug provided such amazing relief. It also helped me lose weight, which was an added bonus.

4/20/2014 I was taking Zelnorm for three years before it was taken off the market. I'm devastated that I can't get it anymore; it did wonders for me, making me feel like a normal person who could do things other people take for granted. Now I use an herbal supplement with senna in it, even though I know I shouldn't because of the potential side effects. Has anyone had any luck buying Zelnorm from other countries?

9/24/2013 IBS was a twenty year nightmare for me, and this medication finally put an end to most of it. For five wonderful years I was able to live relatively symptom-free. But now it's back and there's nothing else like it on the market. We need to find a way to get this treatment available again!

11/3/2010 I'm really hoping that Zelnorm makes a comeback soon. It worked great for me and I haven't been able to find anything else that works as well.
5Patient Review
8/17/2013 I want ZELNORM back on the market! The only over-the-counter medication I have found that is somewhat compatible is magnesium citrate, but I can only take it once a week. Two women complained and they took it off the market?

2/1/2012 Zelnorm was an amazing drug that really helped with my chronic constipation. I haven't been able to find anything that works as well since it was taken off the market.
