Introduction: What is Natamycin?

Natamycin is an antifungal medication primarily used to treat fungal infections. It belongs to a class of drugs known as polyene antifungals and is derived from the bacterium Streptomyces natalensis. Natamycin is effective against a variety of fungal pathogens, making it a valuable option in both clinical and agricultural settings. It is commonly used in the treatment of infections caused by fungi, particularly in the eyes and skin.

Uses of Natamycin

Natamycin is approved for several medical uses, including:

• Infezioni oculari: It is often prescribed for fungal keratitis, an infection of the cornea caused by fungi.
• Infezioni della pelle: Natamycin can be used to treat superficial fungal infections of the skin.
• Conservazione del cibo: In addition to its medical uses, natamycin is also utilized as a food preservative to prevent mold and yeast growth in various food products.

Come funziona

Natamycin works by binding to ergosterol, a key component of fungal cell membranes. This binding disrupts the integrity of the cell membrane, leading to cell death. In simpler terms, natamycin acts like a shield that prevents fungi from maintaining their structure, ultimately causing them to break down and die.

Dosaggio e amministrazione

The dosage of natamycin can vary based on the condition being treated:

• For Ocular Infections: The typical adult dosage is 1 drop of natamycin eye suspension in the affected eye(s) every 1 to 2 hours for the first few days, then reduced as the condition improves.
• Per le infezioni della pelle: A topical formulation may be applied to the affected area 2 to 3 times daily.

I dosaggi pediatrici devono essere determinati da un medico in base all'età e al peso del bambino.
