Description

Sequifenadine is H1- and 5HT-serotonine receptor antagonist. It has an anti-histamine effect, not only blocking histamine receptors, but also reducing the content of histamine in tissues by accelerating its destruction by diamine oxidase. Sequifenadine did not demonstrate any significant sedative effect. It has a pronounced and prolonged antipruritic and antiexudative effect. It is indicated for the treatment of allergic rhinitis and conjunctivitis, pollinosis, urticaria, angioedema, allergic pruritic dermatosis, including atopic dermatitis. Adverse effects are: dry mouth, pain in the epigastric region, dyspepsia, increased appetite, headache, sleepiness.
