Abstract
A pressure detection tablet is disclosed. The tablet is a capsule including a dye encapsulated within an inner coating, in which the inner coating is configured to rupture at a pressure equal to or greater than a pressure threshold. The tablet further includes an outer coating surrounding the capsule, in which the outer coating is configured to provide delivery of the capsule to a targeted site. The dye may be a non-metabolized, water soluble dye, such that a ruptured capsule releases the dye which can be visually detected in the urine. In some embodiments, the disclosure provides a method of making the tablet, using the tablet to detect peak pressure in the colon and reducing the risk of developing a colonic disorder.
