详细说明

DrugBank - DB00341

• Drug Groups: approved
• Description: A potent second-generation histamine H1 antagonist that is effective in the treatment of allergic rhinitis, chronic urticaria, and pollen-induced asthma. Unlike many traditional antihistamines, it does not cause drowsiness or anticholinergic side effects. [PubChem]
• Indication: For the relief of symptoms associated with seasonal allergic rhinitis, perennial allergic rhinitis and the treatment of the uncomplicated skin manifestations of chronic idiopathic urticaria
• Pharmacology: Cetirizine, the active metabolite of the piperazine H₁-receptor antagonist hydroxyzine, is used to treat chronic idiopathic urticaria, perennial allergic rhinitis, seasonal allergic rhinitis, allergic asthma, physical urticaria, and atopic dermatitis.
• Toxicity: Somnolence (sleepiness or unusual drowsiness), restlessness, irritability
• Affected Organisms: Humans and other mammals
• Absorption: mean peak plasma concentration (Cmax) of 114 ng/mL at a time (Tmax) of 2.2 hours postdose was observed for cetirizine
• Half Life: 8.3 hours
• Protein Binding: Very high (93%) plasma protein binding
• Clearance: * 53 mL/min [healthy]
