aerius 5mg dosage

aerius 5mg dosage for adults

  • Adults and adolescents (12 years and older): one tablet once daily, at or outside of meals for the relief of symptoms associated with allergic rhinitis (including intermittent and persistent allergic rhinitis) and urticaria ( see section on pharmacodynamic properties).
    • In adolescents aged 12 to 17, the experience of using desloratadine in clinical efficacy studies is limited (see sections on adverse effects and pharmacodynamic properties).
    • Intermittent allergic rhinitis (presence of symptoms for less than 4 days per week or less than 4 weeks) should be managed based on the patient’s history of to be interrupted after the disappearance of symptoms, and restored to their reappearance.
  • In persistent allergic rhinitis (presence of symptoms over a period of 4 days or more per week and for more than 4 weeks), continuous treatment may be offered to patients during periods of allergen exposure.

how does aerius work

Pharmacotherapeutic group: antihistamines anti-H 1 , ATC code: R06A X27

Action mechanism

  1. Desloratadine is a non-sedating, long-acting antihistamine that exerts a selective antagonist effect on peripheral Hi receptors. After oral administration, desloratadine selectively blocks peripheral histamine H 1receptors as it does not diffuse into the central nervous system.
  2. The antiallergic properties of desloratadine have been demonstrated from in vitro studies Inhibition of the release of pro-inflammatory cytokines such as: IL-4, IL-6, IL-8, and IL-13 by human mast cells / basophils has been demonstrated, as well as inhibition of expression of the P-selectin adhesion molecule on endothelial cells. The clinical relevance of these observations remains to be confirmed.

Clinical efficacy and safety data

  1. In a repeat dose clinical trial in which up to 20 mg daily of desloratadine was administered for 14 days, no statistically or clinically significant cardiovascular effects were observed. In a clinical pharmacology trial, in which desloratadine was administered at a dose of 45 mg daily (nine times the therapeutic dose) for ten days, no QT prolongation was observed.
  2. Repeated dose interaction studies with ketoconazole and erythromycin did not show clinically significant changes in desloratadine plasma concentrations.
  3. Desloratadine does not diffuse easily in the central nervous system. In controlled clinical studies, at the recommended dose of 5 mg daily, there was no increase in the incidence of drowsiness compared with placebo. Aerius administered once a day at a single dose of 7.5 mg did not impair psychomotor performance in clinical trials. In a single dose study in adults, desloratadine 5 mg did not change the standard measurement parameters of flight performance, including subjective sleep exacerbation or piloting activities. a plane.
  4. In clinical pharmacology trials concomitant administration with alcohol did not increase drowsiness or impaired alcohol-induced performance. No significant difference was found between desloratadine and placebo groups in psychomotility tests, whether administered alone or in combination with alcohol.
  5. In patients with allergic rhinitis, Aerius relieved symptoms such as sneezing, runny nose, and pruritus, but also eye pruritus, tearing and redness, and pruritus of the palate. Aerius correctly controlled the symptoms throughout the nycthemeron.

Pediatric population

  1. The effectiveness of Aerius tablets has not been clearly demonstrated in studies in adolescent patients aged 12 to 17 years.
  2. In addition to the established classifications of seasonal and perennial allergic rhinitis, allergic rhinitis may also be classified as intermittent allergic rhinitis and persistent allergic rhinitis depending on the duration of the symptoms. Intermittent allergic rhinitis is defined as the presence of symptoms over a period of less than 4 days per week or over a period of less than 4 weeks. Persistent allergic rhinitis is defined as the presence of symptoms over a period of 4 days or more per week and for more than 4 weeks. 
  3. Aerius decreased the disabling character of seasonal allergic rhinitis, as shown by the total score of the rhino-conjunctivitis quality of life questionnaire. The most significant improvement was observed in the area of ​​practical problems and daily activities limited by symptoms. 
  4. Chronic idiopathic urticaria has been studied as a clinical model of urticarial manifestations, since the underlying pathophysiology is similar, regardless of etiology, and because chronic patients can be more easily recruited prospectively. As histamine release is a factor responsible for all urticarial pathologies, desloratadine is expected to be effective in relieving the symptoms of other urticarial manifestations, in addition to chronic idiopathic urticaria, as recommended in the literature. clinical guidelines.
  5. In two placebo-controlled six-week trials in patients with chronic idiopathic urticaria, Aerius was effective in relieving pruritus and decreasing the number and size of urticaria by the end of the first dose. In each trial, the effects were maintained throughout the nycthemeron. As in other trials of antihistamines in chronic idiopathic urticaria, the few patients identified as non-responders to antihistamines have been excluded. A decrease in pruritus of more than 50% was observed in 55% of patients treated with desloratadine compared to 19% of patients treated with placebo. Aerius treatment also significantly reduced sleep interference and daily activity,

What are the side effects of Aerius?

In clinical trials conducted in allergic rhinitis and chronic idiopathic urticaria, at the recommended dose of 5 mg daily, adverse events were reported in 3% more patients than those treated with placebo.

The most commonly reported adverse events with an incidence greater than placebo were: asthenia (1.2%), dry mouth (0.8%) and headache (0.6%). In a clinical study in 578 adolescent patients aged 12 to 17, the most common adverse event was headache; it occurred in 5.9% of patients treated with desloratadine and in 6.9% of patients receiving placebo.

Other adverse effects that have been very rarely reported since marketing are listed in the following table:

  1. -Psychiatric disorders : Hallucinations.
  2. – Nervous system disorders : Dizziness, drowsiness, insomnia, psychomotor hyperactivity, convulsions.
  3. – Cardiac disorders : Tachycardia, palpitations.
  4. – Gastrointestinal disorders : Abdominal pain, nausea, vomiting, dyspepsia, diarrhea.
  5. – Hepatobiliary disorders : Elevations of liver enzymes, increased bilirubin, hepatitis.
  6. – Musculoskeletal and systemic disorders : Myalgia.
  7. – General disorders : Hypersensitivity reactions (such as anaphylaxis, angioedema, dyspnea, pruritus, rash, and urticaria).

AERIUS Interactions

In clinical trials with desloratadine tablets in which patients received erythromycin or ketoconazole in combination, no clinically significant interactions were observed.

Pediatric population

  • Interaction studies have only been performed in adults.
  • In a clinical pharmacology trial, there was no evidence of potentiation of the deleterious effects of alcohol on performance tests when used with Aerius tablets (see section 5.1 ). However, cases of intolerance and alcohol intoxication have been reported since marketing. Therefore, caution is advised in case of concomitant intake of alcohol.

AERIUS Warnings and Precautions

Aerius should be used with caution in patients with severe renal impairment (see section 5.2 Pharmacokinetic properties ).
