Omeprazole Capsule

Omeprazole is indicated for use to treat certain stomach and esophagus problems such as:

  • Acid reflux
  • Ulcers

Acid reflux

This is a common condition that features a burning pain. It is also known as heartburn in the lower chest area. It happens when stomach acid flows back up into the food pipe. Gastroesophageal reflux disease (GERD) is diagnosed when acid reflux occurs more than twice a week. Acid reflux is when some of the acid content of the stomach flows up into the esophagus and the gullet. In which it moves food down from the mouth. Despite the name, heartburn has nothing to do with the heart. The stomach contains hydrochloric acid, a strong acid that helps break down food. It also protects against pathogens such as bacteria.


This condition causes painful sores in the stomach lining. It occurs when a thick layer of mucus that protects your stomach from digestive juices is reduced. This allows the digestive acids to eat away at the tissues that line the stomach, causing an ulcer. This condition may be easily cured, but they can become severe without proper treatment.

This medication may be also be used for the treatment of:

  • Zollinger-Ellison syndrome – it is where the stomach produces too much acid
  • Dyspepsia – a condition that causes sour stomach, heartburn, belching, and indigestion

Omeprazole helps heal acid damage to the stomach and esophagus. It helps prevent ulcers and may help prevent cancer of the esophagus. This drug relieves symptoms such as:

  • Difficulty swallowing
  • Heartburn
  • Persistent cough

Omeprazole is a proton pump inhibitors. This lessens the amount of acid produced in the stomach. This product is supplied as a delayed-release capsule. Omeprazole is available in the dosage forms of 10 mg, 20 mg, and 40 mg. The Food and Drug Administration (FDA) has already approved this prescription.  

How does Omeprazole work?

Omeprazole works by stopping the proton pumps from working. This reduces the production of stomach acid. Proton pumps are found on cells that line the stomach. These are used by cells to produce stomach acid.

By lessening stomach acid, this drug can help relieve indigestion symptoms as well as painful heartburn symptoms. In which it is caused by excess acid flowing back into the food pipe. It allows the food pipe to heal if it has been damaged by the acid. By reducing the amount of acid in the stomach and upper intestine, Omeprazole allows peptic ulcers to heal and helps stop them from coming back.

Omeprazole helps protect your gut if you are taking an anti-inflammatory painkiller like diclofenac. These painkillers stop your stomach from producing prostaglandins that normally protect your stomach lining from stomach acid. This medication helps to minimize the amount of stomach acid that can irritate your stomach while you’re taking these painkillers.

This medication begins to work depending on how and why you are taking it. You should get some relief from indigestion symptoms and heartburn right away or at least in the first few days after taking a dose of Omeprazole. However, you may need to keep taking Omeprazole for a few weeks some conditions may require you to take this drug on a long-term, basis. Either it is to keep symptoms under control or to avoid the condition from coming back.
