BETADINE ANTISEPTIC 100MG/1ML SOLUTION

Indications

• Skin disinfection
• Ocular antisepsis before surgery
• Treatment of conjunctivitis
• Prevention of infection in minor wounds

Dosage

Children: Refer to product literature for specific dosing recommendations for children, as doses may vary based on the formulation used.

Adults: For ocular antisepsis, apply povidone-iodine solution to the eye area, leave for 2 minutes, then irrigate thoroughly with sodium chloride 0.9%. For skin disinfection, consult product literature for specific dosing instructions.

Mechanism of action

Povidone-iodine releases free iodine, which penetrates microbial cell walls, leading to the disruption of protein synthesis and cellular metabolism. This mechanism results in the bactericidal and virucidal activity of the compound, effectively reducing microbial load on skin and mucous membranes.

Pharmacodynamics

The antiseptic properties of povidone-iodine arise from its ability to disrupt cellular protein synthesis in microorganisms. The solution is effective at low concentrations, and its broad-spectrum activity includes efficacy against both gram-positive and gram-negative bacteria, as well as viruses and fungi. The rapid action of povidone-iodine makes it suitable for preoperative disinfection and wound care.

Pharmacokinetics

Povidone-iodine is primarily used topically, and systemic absorption is minimal when applied to intact skin. When used in ocular applications, the solution can be absorbed across the conjunctival membrane, although the extent of systemic absorption is low. The elimination of iodine from the body primarily occurs via renal pathways, and the half-life can vary based on the route of administration.
