Sodium Metabisulphite

Introduction

Sodium Metabisulphite is a chemical compound widely used in the pharmaceutical, food, and cosmetic industries for its antioxidant and preservative properties. It helps prevent oxidation and spoilage by releasing sulfur dioxide, which inhibits microbial growth. In medical settings, it may be used in the formulation of injections and IV fluids as a stabilizer. Sodium Metabisulphite is a powerful compound that must be used under controlled conditions due to its potential sensitivity and side effects in some individuals.

Uses of Sodium Metabisulphite

• Used as an antioxidant in pharmaceutical preparations
• Preservative in injections and IV fluids
• Prevents oxidation of active drug ingredients
• Helps stabilize formulations containing adrenaline or catecholamines
• Used in food and beverage processing as a preservative (non-medicinal)

How Sodium Metabisulphite works

Sodium Metabisulphite works by releasing sulfur dioxide (SO₂) when it dissolves. This gas has strong antioxidant and antimicrobial properties, which help prevent oxidation and microbial contamination in pharmaceutical products and other formulations. It stabilizes sensitive compounds and prolongs shelf life.

Benefits of Sodium Metabisulphite

• Prevents drug degradation
• Enhances shelf life of pharmaceutical formulations
• Acts as an effective antioxidant
• Maintains potency of sensitive medications
• Useful as a preservative in IV solutions and injectables
