Transit-Pellets device are intended to be used to assess colonic transit time in adult patients with chronic constipation, chronic diarrhea or troublesome IBS. The markers represent the passage of solid and semi-solid contents. The markers are visible during X-ray due to the properties of Barium Sulphate, which is one of the ingredients in the device.
The most common reason to do this investigation is suspicion of so-called slow-transit constipation. However, with the new modification of marker intake on the sixth day, it is also possible to easily measure rapid passage, which could be of interest in the investigation of patients with chronic diarrhea.

The device is prescribed by a physician for the patient to administer the device at home. The device is taken in a transparent HPMC capsule and passes through the mouth, throat and gastrointestinal tract. It is not surgically invasive.
On day seven, the patient undergoes an X-ray examination or fluoroscopy in a clinic.
Based on the number of retained markers and their position a colonic transit time is calculated and compared to reference values.
Times specified above are examples only.
The radiology examination should be scheduled 12 hours after the evening dose day six.
