receptor antagonists may have a potential role in managing bladder conditions such as overactive bladder, they are not typically used in treating cystitis or painful bladder disease, and their mechanism of action in bladder diseases is still not fully understood. There is limited research that

antagonists offer several advantages over antacids, including longer duration of action (6–10 hours vs 1–2 hours for antacids), greater efficacy, and ability to be used prophylactically before meals to reduce the chance of heartburn occurring. Proton pump inhibitors, however, are the preferred

receptor antagonists are less likely to alter CYP metabolism. Ranitidine is not as potent a CYP inhibitor as cimetidine, although it still shares several of the latter's interactions (such as with warfarin, theophylline, phenytoin, metoprolol, and midazolam).
