A common method for assessing the in vitro mucoadhe¬sion of a particular test substance is the measurement of peak detachment force; the force required to separate a potential bioadhesive from mucus or mucosa. There are three types of measurements; tensile testing, in which the stress is applied evenly and perpendicular to the adhesive joint, shear testing in which the stress is applied parallel to the joint, and peel which limits the stress to a fine line at the edge of the joint. Tensile strength measurements, although in this instance do not replicate the physiological environ¬ment of the stomach or the forces encountered, can be used to investigate factors affecting bioadhesion, and provide comparisons between a potential bioadhesive and known bioadhesives. As methods and instruments vary and as each test substance may perform differently under varying conditions, it is generally accepted that the optimum para¬meters should be established for each substance prior to tes
