Heartburn is a painful burning sensation experienced in the upper stomach and chest due to the reflux of acid from the stomach into the oesophagus.
The reflux is a result of relaxation of the lower oesophageal sphincter or the LES which in turn is triggered by many factors, most common being poor diet and lifestyle.
Heartburn is a common and easily curable disorder, by simple remedies and medications but its negligence can lead to a chronic and more problematic form called gastro oesophageal reflux disease (GERD).
Proton Pump Inhibitors (PPIs) for Heartburn Treatment
Heartburn, stomach ulcers, and many other gastric disorders are caused by excessive acid secretion in the stomach.
PPIs are medicines that act on the cells of the stomach that produce gastric juices and the acid.
They work on the last step of the pathway of acid production, which is the proton pump and block it so that less or no acid is produced.
The proton pump (H+/K+ ATPase) helps transport protons or hydrogen ions out of the cell, hence causing acidity in the stomach.
The proton pump inhibitors, as the name suggests, inhibit this transport mechanism and help control the overall acid production in the stomach along with the damage caused by hyperacidity.
PPIs are a little slow in action as the medication takes a few minutes to a few hours to show its maximum effect.
Nevertheless, the effect of these classes of drugs is long term and better than that of antacids and histamine type 2 receptor antagonists, both of which are also used to treat heartburn.
Also, PPIs are used to treat frequent heartburns (that occurs 2 or more days a week) as opposed to antacids which can cure only occasional acidities and refluxes.
PPIs are available in the market as tablets, capsules or syrups and both as a prescription drug or an over the counter medication.
PPIs consist of either one six of the proton pump inhibiting compounds which are used in the medications.
Prescription omeprazole medication comes as delayed release (drug that is released in the intestine to prevent its breakdown in the stomach by acids) capsules or granules to be made into a suspension for consumption.
Over the counter, omeprazole drugs come as delayed-release tablets.
This is to be consumed at least 1 hour before the first meal of the day or as indicated by the doctor or the prescription label.
It is usually to be taken once a day but the dose can be increased up to 2-4 times a day depending on the acid production and only on doctor’s advice.
Over the counter omeprazole is taken once a day for 14 days and the course can be repeated once every 4 months if needed.
Omeprazole delayed-release tablet/capsules are strict to be taken with water without chewing, crushing or breaking.
In case of difficulty in swallowing the drug, it should be mixed (granules from inside the capsule) in applesauce and taken as such with water or as indicated by the doctor.
This mixture of omeprazole tablet/capsule granules and applesauce is not to be stored. Granules of omeprazole to be made into a suspension are also available.
