Bioequivalence study of cyclizine hydrochloride 50 mg tablets in healthy volunteers: a randomized, open-label, single-dose study.

Abstract

BACKGROUND:

Cyclizine is used in the treatment and prevention of nausea and vomiting. We aimed to demonstrate bioequivalence between two formulations of cyclizine 50 mg tablets.

METHODS/RESULTS:

This single-dose, two-treatment, two-period, two-sequence, open-label, randomized crossover study was conducted on 32 healthy male volunteers. The average values for Cmax, Tmax, AUC0-t and AUC0-inf were 21.50 ng/ml, 3.85 h, 423.71 ng.h/ml and 489.26 ng.h/ml, for cyclizine 50 mg (test) versus 20.39 ng/ml, 4.34 h, 410.56 ng.h/ml and 473.86 ng.h/ml for Valoid 50 mg (reference). The 90% CI of the mean ratios of Cmax (geometric mean ratio: 101.81 ng/ml), and AUC0-t (101.81 ng.h/ml) were within the bioequivalence range of 80 to 125%. Both drugs were well tolerated.

CONCLUSION:

Cyclizine 50 mg is bioequivalent to the reference.
