Half-lifeThis section has been translated automatically.

27 h

Pharmacodynamics (Effect)This section has been translated automatically.

Desloratadine is a non-sedating, long-acting, competitive, selective H1-receptor antagonist. Due to its dissolving behaviour, Desloratadine, in contrast to the H1 antihistamines of the 1st generation, no longer reaches the central nervous system or only in extremely small quantities. As a result, Desloratadine has only a very low sedative effect. In vitro Desloratadine shows a much higher affinity to H1 receptors than Loratadine. As a consequence, besides histamine release, the release of proinflammatory cytokines such as interleukin-3, -4, -6, -8 and -13 as well as the expression of the adhesion molecule P-selectin from endothelial cells is inhibited. In clinical studies in patients with seasonal allergic rhinitis, desloratadine alleviated allergic symptoms such as sneezing, nasal secretion, itching, tear secretion and redness of the eyes and especially nasal obstruction, which is not achieved by other antihistamines. Desloratadine has the highest H1-antihistaminergic potency, high anti-allergic, anti-inflammatory and clinical efficacy and side effect rates at placebo level.

IndicationThis section has been translated automatically.

Symptoms in allergic rhinitis and chronic idiopathic urticaria.

Limited indicationThis section has been translated automatically.

  • Severe renal failure. No proof of efficacy and tolerance in children under 2 years of age (syrup) and children under 12 years of age. (tablets).
  • Syrup additionally causes fructose intolerance, glucose-galactose metabolic disorders or saccharase-isomaltase insufficiency.

Pregnancy/nursing periodThis section has been translated automatically.

Insufficient data on use during pregnancy and lactation. As desloratadine enters the breast milk, its use during breastfeeding is not recommended.

Dosage and method of useThis section has been translated automatically.

  • Tablets: Adults and children/young people > 12 years: once/day 5 mg p.o.
  • Syrup: children 2-5 years: once/day 2,5 ml p.o.; children 6-11 years: once/day 5 ml p.o.; adults and teenagers > 12 years: once/day 10 ml p.o.

Undesirable effectsThis section has been translated automatically.

Rarely fatigue, dry mouth, headaches, gastrointestinal problems.

InteractionsThis section has been translated automatically.

Clinically relevant interactions with other drugs have not yet been identified. The effect of alcohol is not enhanced.

ContraindicationThis section has been translated automatically.

Severe renal failure. Hypersensitivity to the active substance or other ingredients of the preparations.

PreparationsThis section has been translated automatically.

Aerius film tablets, Aerius syrup

Note(s)This section has been translated automatically.

Most effective in reducing the symptoms of allergic rhinitis compared to fexofenadine (180 mg) and loratadine (10 mg). In urticaria the dosage can be significantly increased; according to the current EACCI/GA2LEN/EDF guidelines up to four times the recommended dose (e.g. 2-0-2 Tbl./day).
