Fornisce sollievo dai sintomi della sindrome dell'intestino irritabile tra stipsi cronica idiopatica.

Tegaserod è indicato per il trattamento a breve termine delle donne con sindrome dell'intestino irritabile (IBS), il cui sintomo principale è la costipazione intestinale. La sindrome dell'intestino irritabile con costipazione idiopatica cronica e stipsi sono entrambi inferiori dismotilità disturbi gastrointestinali. Le indagini cliniche hanno dimostrato che entrambe le funzioni motorie e sensoriali dell'intestino sembra essere alterata nei pazienti affetti da irritabile sindrome da intestino (IBS), mentre nei pazienti con costipazione idiopatica cronica, ridotta motilità intestinale è la causa predominante della condizione. Sia il sistema nervoso enterico, che agisce per integrare ed elaborare informazioni nell'intestino, e 5-idrossitriptamina (5-HT, serotonina) si pensa di rappresentare gli elementi chiave nell'eziologia di entrambi IBS e costipazione idiopatica. Circa il 95% della serotonina è presente in tutto il tratto gastrointestinale, principalmente conservati nelle cellule enterocromaffini, ma anche nei nervi enterici che funge da neurotrasmettitore. La serotonina ha dimostrato di essere coinvolti nella regolazione motilità, la sensibilità viscerale e la secrezione intestinale. Le indagini suggeriscono un importante ruolo della serotonina di tipo 4 (5-HT4) recettori per il mantenimento delle funzioni gastrointestinali nell'uomo. 5-HT4 mRNA del recettore è stato trovato in tutto il tratto gastrointestinale umano.

Rapidamente assorbito dopo somministrazione orale, con una biodisponibilità assoluta di circa il 10%.

DL50 orale nel ratto è di 2000 mg / kg.

Read this information carefully before you start taking Zelnorm^® (ZEL-norm). Read the information you get each time you get more Zelnorm. There may be new information. This information does not take the place of talking to your doctor about your medical condition or treatment.

What is the most important information I should know about Zelnorm?

If you get new or worse abdominal (stomach) pain, or blood in your stools, stop taking Zelnorm right away and tell your doctor. Your doctor may need to do tests to find out if you have a serious problem with your bowel that may require special treatment or hospitalization.

Sometimes Zelnorm causes diarrhea. Stop taking Zelnorm and call your doctor right away if you get so much diarrhea that you get lightheaded, dizzy, or faint.

What is Zelnorm?

Zelnorm is a medicine for:

• the short-term treatment of women who have irritable bowel syndrome (IBS) with constipation (not enough or hard bowel movements) as their main bowel problem. Zelnorm does not work for all women who use it. Zelnorm has not been shown to work in men with IBS with constipation.
• the treatment of patients less than 65 years of age with chronic idiopathic constipation. Chronic constipation means constipation lasting over 6 months. Idiopathic constipation means constipation not due to other diseases or drugs. Zelnorm has not been shown to work in patients with chronic idiopathic constipation who are 65 years of age or older. Zelnorm increases the movement of stools (bowel movement) through the bowels. Zelnorm does not cure IBS with constipation or chronic idiopathic constipation. For those with IBS with constipation who are helped, Zelnorm reduces pain and discomfort in the abdominal area, bloating, and constipation. For those with chronic idiopathic constipation, Zelnorm increases bowel movements, reduces straining, bloating and abdominal discomfort If you stop taking Zelnorm, your symptoms may return within 1 or 2 weeks.

Who should not take Zelnorm?

You should not start taking Zelnorm if:

• You now have diarrhea or have diarrhea often.
• You have bad kidney or liver disease.
• You have ever had bowel obstruction (intestinal blockage), symptomatic gallbladder disease, or abdominal adhesions causing pain and/or intestinal blockage.
• You are allergic to Zelnorm or any of its ingredients. The active ingredient in Zelnorm is tegaserod maleate. The inactive ingredients are listed at the end of this leaflet.

Zelnorm may not be right for you. Tell your doctor if you:

• Are pregnant or plan to become pregnant. Zelnorm is not recommended for use by pregnant women.
• Are breast-feeding. Do not breast-feed while you are taking Zelnorm. The drug is likely to pass into breast milk.
• Are taking or planning to take any other medicines, including those you can get without a prescription.

How should I take Zelnorm?

• You should take Zelnorm twice a day on an empty stomach shortly before you eat a meal, or as your doctor prescribes it.
• For IBS with Constipation: You should take Zelnorm for 4 to 6 weeks to treat your IBS symptoms. If you feel better, your doctor may prescribe an additional 4 to 6 weeks of Zelnorm.
• For Chronic Idiopathic Constipation: You should talk to your doctor regularly about whether you need to stay on Zelnorm.
• If you miss a dose of Zelnorm, just skip that dose. Do not take two tablets to make up the missed dose. Instead, just wait until the next time you are supposed to take it and then take your normal dose.

What are the possible side effects of Zelnorm?

Headache and diarrhea were the most common side effects seen with Zelnorm.

Diarrhea was an occasional side effect of treatment with Zelnorm. Most people who got diarrhea had it during the first week after starting Zelnorm. Typically, diarrhea went away with continued therapy. If you get bad diarrhea, or if you get diarrhea together with bad cramping, abdominal pain, fainting, or dizziness, tell your doctor. Your doctor may tell you to stop taking Zelnorm or suggest other ways to manage your diarrhea.

There have been rare cases of rectal bleeding and severe abdominal pain in patients treated with Zelnorm. Some of these problems were related to insufficient blood flow to part of the bowel. It is not known if this was related to Zelnorm use.

In studies a very small number of patients were reported to have abdominal surgery. In IBS with constipation studies there were a few more reports of abdominal surgery in patients taking Zelnorm than in patients taking a sugar pill. Most of these were related to the gallbladder. It is not known if Zelnorm may increase your chance of abdominal surgery. Gallbladder surgery has been reported to occur more often in IBS patients than in the general population.

This list is not complete. Your doctor or pharmacist can give you a more complete list of possible side effects. Talk to your doctor about any side effects you may have.
