Infobox references

Niperotidine is a histamine antagonist selective for the H2 subtype. It was trialled as a treatment for excessive gastric acidity,[1] but withdrawn after human trials showed liver damage.[2]

Adverse effects

Antacid preparations such as niperotidine by suppressing acid mediated break down of proteins, leads to an elevated risk of developing food or drug allergies. This happens due to undigested proteins then passing into the gastrointestinal tract where sensitisation occurs. It is unclear whether this risk occurs with only long-term use or with short-term use as well.[3]
