Biological Activity

[Description]:

Bromodiphenhydramine hydrochloride is a potent antihistamine with antimicrobial property. Bromodiphenhydramine hydrochloride inhibits a large number of Gram negative and Gram positive bacteria. Bromodiphenhydramine hydrochloride can be used for cutaneous allergies research[1][2][3].

[In Vivo]

Bromodiphenhydramine hydrochloride (1.5 and 3 μg/g, single) protects mice against a challenge with a virulent strain of Salmonella typhimurium, and also significantly reduces the multiplication of this organism in the liver, spleen and blood of the protected animals in comparison with the unprotected controls[2].
