Answer

Antihistamines

These agents act by competitive inhibition of histamine at the H1 receptor. This mediates the wheal and flare reactions, bronchial constriction, mucous secretion, smooth muscle contraction, edema, hypotension, CNS depression, and cardiac arrhythmias.

Diphenhydramine (Anti-HIst, Aler-Dryl, Benadryl)

This is a first-generation antihistamine with anticholinergic effects that binds to H1 receptors in the CNS and the body. It competitively blocks histamine from binding to H1 receptors. It is used for symptomatic relief of symptoms caused by release of histamine in allergic reactions and may be used in patients that experience transfusion related reactions, in particular with FFP.
