What is Omeprazole?

Omeprazole belongs to a group of medicines known as proton-pump inhibitors (PPIs). It is a commonly prescribed and effective acid reflux treatment.

As a Proton Pump Inhibitor (PPI), Omeprazole works by suppressing the activity of proton pumps, which produce acids in the stomach. This decreases the amount of acid in your stomach, relieving acid reflux and the symptoms of heartburn.

Omeprazole is available in doses of 10mg, 20mg and 40mg, however omeprazole is also available over the counter in lower doses than the typical prescription strength versions of Omeprazole.

What is Omeprazole used to treat?

Stomach acid is vital for the digestive process, as it breaks down the food before it reaches the intestine. The oesophagus is protected from these acids by a group of muscles, but sometimes an excessive amount of acid can enter the oesophagus, which is known as acid reflux.

This medicine can relieve symptoms for up to 72 hours; the acid levels in your body will return to their previous levels between three and five days after you stop taking Omeprazole.

Omeprazole 20mg can also be used to treat Gastritis. It is also highly recommended for individuals taking over the counter painkillers such as naproxen or aspirin on a consistent basis as this can erode the stomach lining leading to Gastritis.

Why is Omeprazole recommended for treating acid reflux?

Omeprazole has been used to treat acid related conditions since 1989. Omeprazole is a widely used medicine and is often included on the World Health Organization's List of Essential Medicines which lists medicine considered to be the safest and most effective for the global health system.

Proton Pump Inhibitors as a drug class, including Omeprazole; are considered to be remarkably safe and effective at treating individuals with peptic ulcer disorders.

Adverse effects in people currently using PPI's is also estimated to be extremely low at just 1-3% of all patients. 

How do Omeprazole capsules work?

Proton pumps are very small substances located within the lining of the stomach, that help the stomach to produce acid in order to digest food. Omeprazole is a proton pump inhibitor and works by stopping the proton pumps from working properly and as a result decreases the level of acid that is produced.

The inhibitory effects of Omeprazole are fast acting and can be felt within just 1 hour of taking it. The maximum effects of Omeprazole will occur within 2 hours and can last for approximately 72 hours.
