    Scoring of the severity of pruritus

    Two hours after the treatment was completed

Study Arms (2)

Arm 1

EXPERIMENTAL

Cetirizine hydrochloride injection;diphenhydramine hydrochloride injection simulator

Drug: Cetirizine Hydrochloride Injection

Arm 2

EXPERIMENTAL

diphenhydramine hydrochloride injection ;Cetirizine hydrochloride injection simulant

Drug: Diphenhydramine Hydrochloride Injection

Interventions

The subjects received a single dose of 1-2 ml of the injection of cetirizine hydrochloride (administered by intravenous push) and a 1 ml dose of the injection simulant of diphenhydramine hydrochloride (administered by deep intramuscular injection), both as a simulation of a single administration.

Also known as: Simulant of Diphenhydramine Hydrochloride Injection
Arm 1

The subjects received 1 ml of the injection of Diphenhydramine Hydrochloride (for deep intramuscular injection) and 1 ml of the injection of Simulated Cetirizine Hydrochloride (administered by rapid intravenous injection over 1 to 2 minutes), each as a single dose.
