Cetirizine in Cvetox, a human metabolite of hydroxyzine, is a potent and selective antagonist of peripheral H1-receptors.
1 ml oral solution contains: cetirizine dihydrochloride – 1 mg
Due to the pharmacokinetic, pharmacodynamic and tolerance profile of cetirizine, no interactions are expected with this antihistamine. Actually, neither pharmacodynamic nor significant pharmacokinetic interaction was reported in drug-drug interactions studies performed, notably with pseudoephedrine or theophylline (400 mg/day).
The extent of absorption of cetirizine is not reduced with food, although the rate of absorption is decreased.
