Proton Pump Inhibitors

How Do Proton Pump Inhibitors Work?

Proton Pump Inhibitors

The stomach produces non-acidic potassium ions, which keep the acidic environment inside the organ at a fairly constant and stable level. A proton pump is a complex molecular machinery, which is made up of integral proteins that aims to move protons across any membrane. In doing so, the pump creates an electrochemical gradient, which is useful in manufacturing energy.

However, due to the fact that the molecule pumps proton inside an organelle or an organ, for example the stomach, the environment inside the membrane increases in acidity. With increased concentrations of acidic substances inside the stomach, a person usually experiences a condition known as acid reflux.

This is the primary reason why scientists and doctors have come up with a set of drugs known as proton pump inhibitors, which could stop the proper functioning of a proton pump hence treating the medical condition. The mechanism of action of a proton pump inhibitors lie in its capacity to lower acidity levels.

Proton pump inhibitors are drugs that target the enzyme that produces acid along the lining of the stomach. This acidic enzyme is part of the normal metabolism of the human body. It is used by the stomach to further digest the food and, in some cases, to eradicate living bacteria.

However, if the acid concentration inside the stomach reaches a critical level wherein the mucus covering the sensitive lining of the stomach has already broken down, the person immediately experiences a condition known as ulcer. The increased concentrations of acid in the stomach likewise makes a person regurgitate the excess concentrations thus leading to a condition known as acid reflux.

In almost all of these cases, proton pump inhibitors dislodge the molecular machineries of the proton pump. The consequence is that the pump stops and eventually stops functioning, thus allowing for the body to regenerate the normal ph levels inside the stomach. Molecularly speaking, proton pump inhibitors stops the transport of hydrogen ion towards the cells of the stomach, thus effectively reducing the acidity. The basic mechanism of these drugs is to disrupt the proper functioning of the proton pump inside the lining of the stomach. Proton pump inhibitors aim to maintain the normal levels of acid inside the organ.
