English to Spanish Medical Medical: Pharmaceuticals unformed bowel movement

Buenos días,

Espero que puedan ayudarme con la siguiente expresión al español: “unformed bowel movement”, relacionada con un producto farmacéutico. Muchas gracias:

“In a placebo-controlled trial, patients with diarrhoea of infectious origin received two 50mg capsules of product X on day 1, and 1 capsule after each unformed bowel movement, until diarrhea resolution. There were no significant differences between the two groups.”
