Secretory diarrhea is a leading cause of morbidity and mortality worldwide. Crofelemer is a first-in-class antidiarrheal agent that simultaneously targets two distinct channels, the cystic fibrosis conductance regulator and calcium-activated chloride channel, responsible for chloride and fluid secretion in the GI tract. Crofelemer is a novel compound extracted from the stem bark latex of the Croton lechleri tree found in the western Amazonian region of South America. There is little to no systemic absorption of crofelemer when given orally and studies have shown minimal toxicity beyond mild gastrointestinal effects. In studies in diarrheal illness associated with primarily a secretory component, such as cholera, travelers' diarrhea and acute infectious diarrhea, crofelemer has shown improvements in stool consistency and duration of symptoms. Less clear, but interesting, results have been observed in other diarrheal diseases associated with a mixed pathology, including diarrhea in patients with HIV and diarrhea-predominant irritable bowel syndrome.

Secretory diarrhea has a significant impact on morbidity and mortality worldwide and may be a predominant or minor component of pathogenesis in diarrhea of various etiologies. Crofelemer is a first-in-class antidiarrheal medication with unique inhibitory mechanisms at both the cystic fibrosis transmembrane conductance regulator and the calcium-activated chloride channels which are responsible for chloride secretion and subsequent luminal hydration. The efficacy of crofelemer has been investigated in patients with HIV-associated diarrhea, diarrhea of various infectious etiologies, as well as diarrhea-predominant irritable bowel syndrome. Crofelemer was approved by the FDA in December 2012 to treat diarrhea in HIV/AIDS patients on antiretroviral therapy. Crofelemer is not absorbed in the body and well-tolerated in small trials performed to date although long-term safety data is lacking. Crofelemer may be an important addition to the currently available drugs for the management of secretory diarrhea.
