How FCV Protect works

Information regarding the mechanism of action of boric acid in mediating its antibacterial or antifungal actions is limited. Boric acid inhibits biofilm formation and hyphal transformation of Candida albicans, which are critical virulence factors . In addition, arrest of fungal growth was observed with the treatment of boric acid .

Toxicity

The acute oral LD₅₀ in rats is 4500-5000 mg/kg and the intradermal LD₅₀ in rabbits is 10,000 mg/kg. Individuals are likely to be exposed to boric acid from industrial manufacturing or processing. Local tissue injury from boric acid exposure is likely due to caustic effects. Systemic effects from boric acid poisoning usually occur from multiple exposures over a period of days and involve gastrointestinal, dermal, CNS, and renal manifestations. Gastrointestinal toxicity include persistent nausea, vomiting, diarrhea, epigastric pain, hematemesis, and blue-green discoloration of the feces and vomit . Following the onset of GI symptoms, a characteristic intense generalized erythroderma follows . Management of mild to moderate toxicity should be supportive. In case of severe toxicity, dialysis may be required in addition to supportive treatment.

Volume of Distribution

Volume of distribution ranges from 0.17 to 0.5 L/kg in humans, where large amounts of boric acid are localized in brain, liver, and kidney .

Elimination Route

Boric acid is well absorbed from the gastrointestinal tract, open wounds, and serous cavities but displays limited absorption in intact skin . Following intraperitoneal injection in mice, the peak concentration was reached in about 1.0-1.5 hr in the brain whereas the value was 0.5 hr in other tissues .

Half Life

According to human cases of poisoning, the elimination half-life of boric acid ranges from 13 to 24 hours .

Clearance

A case report of acute boric acid poisoning following oral ingestion of 21 g of boric acid presents the total body clearance of 0.99 L/h before hemodialysis .

Elimination Route

Regardless the route of administration, boric acid predominantly undergoes rapid renal excretion of >90% of total administered dose as unchanged form. Small amounts are also excreted into sweat, saliva, and feces. Following administration as ointment, urinary excretion of boric acid accounted for only 1% of the administered dose .
