The H1-receptor antagonist chlorpheniramine decreases the ending phase of the mismatch negativity of the human auditory event-related potentials.

Auditory event-related potentials (ERPs) were recorded in 20 healthy male humans, who received either a single 4 mg dose of d-chlorpheniramine or a placebo, according to a double-blind design. Subjects were instructed to read a book and to ignore random sequences of 90% standard (1000 Hz) and 10% deviant (1100 Hz) tones, presented with stimulus-onset asynchrony (SOA) of 480 ms. Deviant tones elicited the mismatch negativity (MMN) response, which was smaller at its ending phase in the chlorpheniramine group. The auditory exogenous components (N1 and P2) were similar in both groups. Results demonstrate that the antihistamine chlorpheniramine selectively affects the automatic stimulus-change detector associated with MMN, and suggest an involvement of the histamine H1-receptor in the genesis of the MMN.[1]
