How does Amitiza work?
Amitiza activates specific chloride channels (ClC-2) in the intestinal epithelium. This activation leads to an increase in intestinal fluid secretion without altering sodium or bicarbonate concentrations. The increased fluid helps to moisten the stool and stimulate intestinal motility, facilitating bowel movements [1].

Dosage varies depending on the condition being treated. For chronic idiopathic constipation, the usual dose is 24 mcg twice daily [1]. For IBS-C in women, the dose is typically 8 mcg twice daily [1]. For opioid-induced constipation, the dose is 24 mcg twice daily [1]. It is important to follow a healthcare provider's prescription.
