Betadine® 5% Sterile Ophthalmic Prep Solution (povidone-iodine ophthalmic solution) (0.5% available iodine)
Povidone-Iodine is a broad-spectrum microbicide with the chemical formulas: 2-pyrrolidinone, 1- ethenyl-, homopolymer, compound with iodine; 1-vinyl-2-pyrrolidinone polymer, compound with iodine. The structural formula is as follows:
BETADINE® 5% Sterile Ophthalmic Prep Solution contains 5% povidone-iodine (0.5% available iodine) as a sterile dark brown solution stabilized by glycerin. Inactive Ingredients: citric acid, glycerin, nonoxynol-9, sodium chloride, sodium hydroxide, and dibasic sodium phosphate.
A placebo-controlled study in 38 normal volunteers yielded data for 36 subjects who showed a mean log10 reduction of 3.05 log10 units in total aerobes at 10 minutes following prepping the skin with BETADINE 5% Sterile Ophthalmic Prep Solution compared with reduction of 1.58 log10 units after prepping with vehicle free of the iodine complex. This placebo-controlled study indicates a mean log10 reduction by the iodine complex compared with the control solution of 1.47 log10 units at 10 minutes and 1.79 log10 units at 45 minutes. The base-line mean aerobic bacterial count was 7,586 organisms per square cm.
INDICATIONS AND USAGE
BETADINE 5% Sterile Ophthalmic Prep Solution for the eye is indicated for prepping of the periocular region (lids, brow, and cheek) and irrigation of the ocular surface (cornea, conjunctiva, and palpebral fornices).
Do not use on individuals known to be sensitive to iodine, or other components of this product.
No studies are available in patients with thyroid disorders; therefore, caution is advised in using BETADINE 5% Sterile Ophthalmic Prep Solution in these patients due to the possibility of iodine absorption.
Carcinogenesis, Mutagenesis, Impairment of Fertility
No long term studies in animals have been performed to evaluate the carcinogenic or mutagenic potential of povidone-iodine. One report of the mutagenic potential of povidone-iodine indicated that it was positive in a modification of the Ames S. typhimurium model, but these results could not be reproduced by another researcher. Another test using mouse lymphoma and Balb/3T3 cells showed that povidone-iodine has no significant mutagenic or transformation capabilities. Other data indicated that it does not produce mutagenic effects in mice or hamsters according to the dominant lethal test, micronucleus test, and chromosome analysis.
Pregnancy Category C
Animal reproduction studies have not been conducted with BETADINE® 5% Sterile Ophthalmic Prep Solution. It is also not known whether BETADINE 5% Sterile Ophthalmic Prep Solution can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. BETADINE 5% Sterile Ophthalmic Prep Solution should only be used on a pregnant woman if clearly needed.
Because of the potential for serious adverse reactions in nursing infants from BETADINE 5% Sterile Ophthalmic Prep Solution, a decision should be made to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
Local sensitivity has been exhibited by some individuals to povidone-iodine ophthalmic solution.
