VINODINE-5 / POVIDONE-IODINE

DESCRIPTION

VINODINE-5 is a brand name for a product containing the active ingredient Povidone-Iodine. It is an antiseptic and germicidal agent used for topical application. The “5” in VINODINE-5 likely refers to the concentration, which is typically 5% w/w Povidone-Iodine in some formulations, which provides 0.5% w/w available iodine.

  Mechanism of Action

Povidone-iodine, also known as iodopovidone, is a chemical complex of polyvinylpyrrolidone (povidone, PVP) and elemental iodine. It works by slowly releasing free iodine, which has a broad range of microbicidal activity. The iodine kills microorganisms by oxidizing essential proteins, nucleotides, and fatty acids, leading to cell death. It is effective against:

• Bacteria
• Fungi
• Viruses
• Protozoa

Uses

VINODINE-5 / Povidone-iodine is primarily used for the treatment and prevention of common skin infections. It is a common component of first-aid kits and is used in a medical setting for:

• Minor cuts, scrapes, and abrasions: To prevent infection.
• Minor burns: To disinfect and help with the healing process.
• Ulcers and boils: To promote a clean, germ-free environment.
• Surgical preparation: To disinfect the skin before and after surgery.
• Lacerations (deep cuts): To treat and prevent infection, though caution is advised on large, open wounds.

Forms and Application

Warnings and Contraindications:

• Allergies: Do not use if you have a known allergy or hypersensitivity to povidone-iodine or its components.
• Thyroid Issues: Use with caution if you have thyroid problems (e.g., hyperthyroidism, goiter) as the body can absorb iodine from the product, which may interfere with thyroid function tests.

• Large or Deep Wounds: Avoid using on large areas of the body, deep puncture wounds, or severe burns without medical supervision, as there is a risk of excessive iodine absorption.

• External Use Only: Do not swallow or get the product in your eyes. If accidental contact occurs, rinse thoroughly with water.
