Our product portfolio is built on botanical compounds that have the potential to address worldwide unmet medical needs for a variety of gastrointestinal indications.

potential indications

Crofelemer is a novel, first-in-class inhibitory modulator of two secretory chloride ion channels in the gastrointestinal tract. As an antisecretory, antidiarrheal drug, it has a normalizing effect on the electrolyte and fluid balance in the gut. This mechanism of action has the potential to benefit multiple gastrointestinal disorders. Crofelemer has been studied in more than 3,000 patients to date, for a variety of potential indications. Crofelemer is FDA-approved for symptomatic relief of noninfectious diarrhea in adults living with HIV/AIDS who are on antiretroviral therapy (ART).

indication

Mytesi® (crofelemer) is an anti-diarrheal drug indicated for symptomatic relief of non-infectious diarrhea in adults living with HIV/AIDS who are on antiretroviral therapy (ART).

important safety information

Mytesi is not indicated for the treatment of infectious diarrhea. Rule out infectious etiologies of diarrhea before starting Mytesi. If infectious etiologies are not considered, there is a risk that patients with infectious etiologies will not receive the appropriate therapy and their disease may worsen. In clinical studies, the most common adverse reactions occurring at a rate greater than placebo were upper respiratory tract infection (6%), bronchitis (4%), cough (4%), flatulence (3%), and increased bilirubin (3%).
