The drug Amitiza (lubiprostone) has been approved for treatment of chronic constipation in adults with no known cause for the condition, the US Food and Drug Administration said Tuesday.
This drug, the first of its chemical type, will be available as capsules to treat chronic idiopathic constipation, defined as infrequent or difficult passage of stool.

The condition affects women more often than men and is more common in people older than 65. Symptoms include abdominal pain and discomfort, bloating, straining, and hard stools.
Amitiza increases intestinal fluid secretion, which helps ease passage of stool and alleviate symptoms associated with chronic idiopathic constipation, the FDA said.
The agency's approval is based on two clinical trials of the drug that concluded that taking the drug was associated with higher frequency of bowel movements. Side effects included headache, nausea, diarrhoea, abdominal pain, and distension.
The drug is taken twice a day with food, the FDA said. – (HealthDayNews)
