Can a Toothpaste Assist Shield Adults Allergic to Peanuts?

Nov. 16, 2023 – A brand new toothpaste is displaying promise as a remedy to assist adults who’re allergic to peanuts tolerate rising quantities of peanut protein.

The investigational toothpaste is labeled INT301 and it met its security objectives in an early randomized, placebo-controlled trial.

Thirty-two adults, ages 18-55, who had been allergic to peanuts, had been enrolled within the 4-month trial. The contributors had been randomly positioned into teams that acquired both rising quantities of the peanut protein within the toothpaste to check how a lot they might tolerate safely or a placebo toothpaste that had no peanut proteins. The toothpaste was squeezed from a metered dispenser to regulate the quantity. 

Neither the individual giving the contributors the toothpaste, nor the affected person knew which form of toothpaste they received, to assist eradicate potential bias.
