Eno is a brand of antacid that is commonly used to relieve symptoms of indigestion, heartburn, and acid reflux. It is known for its effervescent properties, which help to neutralize stomach acid quickly. Eno is available in various flavors and is widely used around the world.

History

Eno was first developed in the 19th century by James Crossley Eno, a pharmacist from Newcastle upon Tyne, England. The product gained popularity due to its effectiveness in treating digestive discomfort and its easy-to-use effervescent form. Over the years, Eno has become a household name in many countries.

Composition

Eno typically contains a combination of sodium bicarbonate, citric acid, and sodium carbonate. These ingredients react with water to produce carbon dioxide gas, which creates the effervescent effect. This reaction helps to neutralize excess stomach acid, providing relief from symptoms of indigestion and heartburn.

Mechanism of Action

The active ingredients in Eno work by neutralizing stomach acid. When Eno is dissolved in water, the sodium bicarbonate reacts with the citric acid to produce carbon dioxide gas, which causes the solution to fizz. This reaction also produces sodium citrate, which acts as an antacid by neutralizing hydrochloric acid in the stomach. This process helps to alleviate discomfort associated with acid indigestion and heartburn.

Usage

Eno is typically taken by dissolving a sachet or a teaspoon of the powder in a glass of water. It is recommended to drink the solution immediately after it has been prepared to ensure maximum effectiveness. Eno is often used for quick relief of symptoms and is not intended for long-term treatment of chronic conditions.

Flavors and Variants

Eno is available in a variety of flavors, including lemon, orange, and cola. These flavors make the product more palatable and appealing to a wide range of consumers. In addition to the standard formulation, there are also sugar-free variants available for those who are monitoring their sugar intake.

Market and Availability

Eno is widely available in pharmacies, supermarkets, and online retailers. It is marketed in many countries and is a popular choice for those seeking over-the-counter relief from digestive discomfort. The brand is owned by GlaxoSmithKline, a major pharmaceutical company.
