This accounts for about half of all gastric cancers. This has led pathologists to believe that chronic gastritis leads to internal metaplasia (cell changes) which then become malignant. Drugs that inhibit/neutralize acid Proton pump inhibitors PPIs are one the most frequently prescribed classes of drug worldwide, due to their efficiency and low toxicity. However, there is evidence to suggest that PPIs are over-prescribed and that between 25 and 70 per cent of patients have no real indication of needing them.

Firstly, it causes a decrease of conduction of electrical impulses through the AV node. Secondly, it increases the force of contraction via inhibition of what is known as the sodium-potassium pump. This is rather like a revolving door in the wall of a cardiac cell which allows two molecules of potassium into the cell and removes three molecules of sodium. In so doing, it restores the chemical balance between the inside and outside of the cell so that it can contract again. Digoxin inhibits this ‘revolving door’ mechanism which results in an increase in the level of sodium ions in the myocytes (cardiac muscle cells).
