Proporciona un alivio de los síntomas del síndrome del intestino irritable como estreñimiento idiopático crónico.
Tegaserod está indicado para el tratamiento a corto plazo de mujeres con síndrome del intestino irritable (IBS), cuyo principal síntoma es el estreñimiento. El síndrome del intestino irritable con estreñimiento idiopático crónico y estreñimiento son los trastornos de la motilidad gastrointestinal. Las investigaciones clínicas han demostrado que tanto las funciones motoras y sensoriales del intestino parece estar alterada en los pacientes que sufren de irritabilidad El síndrome del intestino (IBS), mientras que en pacientes con estreñimiento idiopático crónico, reducción de la motilidad intestinal es la causa predominante de la enfermedad. Tanto el sistema nervioso entérico, que actúa para integrar y procesar la información en el intestino, y 5-hidroxitriptamina (5-HT, serotonina) se cree que representan elementos clave en la etiología de los SCI y la constipación idiopática. Aproximadamente el 95% de la serotonina se encuentra en todo el tracto gastrointestinal, principalmente almacenada en las células enterocromafines, sino también en los nervios entéricos actúa como un neurotransmisor. La serotonina se ha demostrado que interviene en la regulación la motilidad, la sensibilidad visceral y la secreción intestinal. Las investigaciones sugieren un importante papel de los receptores de serotonina de tipo 4 (5-HT4) en el mantenimiento de las funciones gastrointestinales en los seres humanos. 5-HT4 ARNm del receptor se ha encontrado en todo el tracto gastrointestinal humano.
Absorbe rápidamente tras la administración oral, con una biodisponibilidad absoluta de aproximadamente el 10%.

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

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.

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.

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.

side effects. Talk to your doctor about any side effects you may have.
