<p>Diloxanide is a luminal amoebicide which is hydrolysed in the gut, thus releasing the free diloxanide which acts as an amoebicide. It is given alone in asymptomatic cyst passers. For patients with active amoebic infections, it can be administered with a 5-nitroimidazole e.g. metronidazole or tinidazole.</p>
