Constella – Linaclotide Uses, Dose, And Side Effects


Constella 290 microgram Linaclotide Hard Capsules

1. What Constella Is And What It Is Used For

What Constella is used for?
Constella contains the active substance linaclotide and is used to treat the symptoms of moderate to severe irritable bowel syndrome (often called IBS) with constipation in adult patients.

IBS is a common intestinal disease. The main symptoms of constipation IBS include:

  • Abdominal or abdominal pain
  • Feeling of bloating
  • Irregular, hard, small, or pellet-like stools.

These symptoms may vary from person to person.

How Constella works 
Constella acts locally in the intestine to relieve pain and swelling and to restore normal bowel function. It is not absorbed into the body but attaches to a receptor on the surface of the intestine called guanylate cyclase C. By attaching to this receptor, the drug blocks the sensation of pain and allows fluid from the body to enter the intestine to thereby relieve constipation by dissolving the contents of the intestines. and increase bowel movements.

Pregnancy And Breastfeeding

There is only limited information on the effects of Constella on pregnant and lactating women.
