PHARMACOLOGY

Lubiprostone is a locally acting chloride channel activator that enhances a chloride-rich intestinal fluid secretion without altering sodium and potassium concentrations in the serum. Lubiprostone acts by specifically activatingClC-2, which is a normal constituent of the apical membrane of the human intestine. By increasing intestinal fluid secretion, Lubiprostone increases motility in the intestine, thereby facilitating the passage of stool and alleviating symptoms associated with constipation. After administration, Lubiprostone and its metabolites are observed only on the apical (luminal) portion of the gastrointestinal epithelium. Additionally, activation of ClC-2 by Lubiprostone recovers mucosal barrier function via restoration of tight junction protein complexes. Lubiprostone relieves symptoms within 24 hours.

DOSAGE & ADMINISTRATION

Chronic Idiopathic Constipation: Lubiprostone 24 mcg twice daily orally with food and water.Opioid-induced Constipation: Lubiprostone 24 mcg twice daily orally with food and water.Irritable Bowel Syndrome with Constipation: Lubiprostone 8 mcg should be taken twice daily orally with food and water.

INTERACTION

Based upon the results of in vitro human microsome studies, there is low likelihood of drug-drug interactions. In vitro studies using human liver microsomes indicate that cytochrome P450 isoenzymes are not involved in the metabolism of Lubiprostone. Based on the available information, no protein binding–mediated drug interactions of clinical significance are anticipated.

SIDE EFFECTS

Nausea, vomiting, loose stools, dry mouth, stomach discomfort, headache, dizziness etc.
