- PPI proton pump inhibitors
- the stability of these compounds is unstable to bad humidity, temperature, light, acid, etc.
- these compounds are unstable to acids and become extremely unstable in aqueous solutions or suspensions as the pH decreases. Therefore, when these compounds are orally administered, they may be decomposed by gastric acid or the like and cannot fully exert their activity.
- the stability of these compounds in preparations such as tablets, powders, fine granules, capsules, etc. becomes unstable due to strong interaction with other ingredients in the formulation rather than the compound alone. Color change or degradation may be observed at times and upon storage.
