Short general description of the drug

What is Nexium?

Nexium is a proton pump inhibitor (PPI) medication that belongs to a class of drugs known as anti-ulcer agents. It is commonly prescribed to reduce the production of stomach acid and is available in both prescription and over-the-counter formulations.

How does Nexium work in the body?

Nexium works by blocking the enzyme responsible for producing acid in the stomach. It inhibits the hydrogen-potassium ATPase enzyme, also known as the proton pump, thereby reducing the secretion of gastric acid. This helps alleviate symptoms associated with various gastrointestinal conditions.

What conditions does Nexium treat?

Nexium is primarily used to treat conditions such as gastroesophageal reflux disease (GERD), heartburn, and gastric ulcers caused by excessive stomach acid. It can also be prescribed in combination with antibiotics for the eradication of Helicobacter pylori bacteria in patients with peptic ulcers.

Common side effects of Nexium

  • Headache
  • Nausea
  • Diarrhea
  • Abdominal pain
  • Flatulence

It is important to note that these side effects are not experienced by everyone and may vary from person to person. It is advisable to consult a healthcare professional if any concerning symptoms occur while taking Nexium.
