Preparations whereby gastric pH value can be conveniently and noninvasively measured, for example, preparations whereby gastric pH value can be measured by using expiration. These preparations can be obtained by coating a composition containing a compound labeled with an isotope (13C, 14C, 15N, 18O, etc.) with a base having a pH-dependent solubility.
L'invention se rapporte à des préparations permettant de mesurer de manière pratique et non invasive la valeur du pH gastrique, et notamment à des préparations qui permettent de mesurer cette valeur au moyen de l'expiration. Ces préparations peuvent être obtenues par enrobage d'une composition contenant un composé étiqueté par un isotope (?13¿C, ?14¿C, ?15¿N, ?18¿O, etc.) avec une base ayant une solubilité dépendante du pH.
