Inactive Ingredients:
- Propylene glycol
- Sorbitol liquid
- Citric acid anhydrous
- Sodium citrate dihydrate
- Sodium benzoate
- Disodium edetate
- Sucrose
- Natural and artificial flavor
- Sunset yellow F.C.F
- Purified water
How AERIUS Syrup Works
Desloratadine is a non-sedating, long-acting histamine antagonist [a drug that blocks the effects of histamine, a substance in the body responsible for allergic reactions]. It works by selectively inhibiting H1-receptors [specific sites in the body where histamine exerts its effects], preventing allergic symptoms. Additionally, it exhibits antiallergic and anti-inflammatory properties, helping to reduce allergic responses.
Preclinical Toxicology
Desloratadine is the primary active metabolite of loratadine. Studies have shown that AERIUS Syrup does not pose a significant risk of toxicity. There are no concerns regarding genotoxicity [the potential to damage genetic material] or reproductive toxicity [harmful effects on fertility or development].
Clinical Pharmacology
Pharmacodynamic Properties
After oral administration, desloratadine selectively blocks peripheral histamine H1-receptors, as it does not significantly penetrate the central nervous system (CNS) [the brain and spinal cord]. Studies in pediatric patients (6 months – 11 years) have demonstrated the safety and efficacy of AERIUS Syrup at recommended doses.
Cardiovascular Safety
Even at high doses (up to 20 mg daily for 14 days or 45 mg daily for 10 days), AERIUS Syrup did not cause any significant cardiovascular effects, including QTc prolongation [a heart rhythm abnormality].
Interaction with Other Substances
- AERIUS Syrup does not significantly interact with ketoconazole, erythromycin, azithromycin, fluoxetine, or cimetidine.
- Alcohol consumption does not enhance its sedative effects.
- It does not impair psychomotor performance [physical tasks requiring cognitive function], including activities such as driving and flying.
Indications and Usage
AERIUS Syrup is indicated for the rapid relief of allergic rhinitis [inflammation of the nasal passages due to allergens] and urticaria [hives].
Allergic Rhinitis
- Includes intermittent [symptoms present for less than 4 days per week or 4 weeks per year] and persistent [symptoms occurring for 4 or more days per week and lasting more than 4 weeks].
- Relieves symptoms such as sneezing, nasal discharge, congestion, ocular itching, tearing, and palate itching.
Urticaria (Hives)
- Helps relieve itching and reduces the size and number of hives.
Dosage and Administration
Children:
- 1-5 years: 2.5 ml (1.25 mg) once daily
- 6-11 years: 5 ml (2.5 mg) once daily
Adults and Adolescents (12+ years):
- 10 ml (5 mg) once daily
- Can be taken with or without food.
Pharmacokinetics
- Absorption: Detectable in plasma within 30 minutes; peak levels in 3 hours.
- Half-life: ~27 hours, allowing for once-daily dosing.
- Metabolism: Not significantly affected by CYP3A4 or CYP2D6 enzymes [proteins that help break down drugs].
- Food Effect: High-fat meals and grapefruit juice do not alter absorption.
Warnings and Precautions
- Should be used with caution in patients with severe renal impairment [kidney dysfunction].
- The enzyme responsible for desloratadine metabolism is unknown, so potential drug interactions cannot be ruled out.
Side Effects
AERIUS Syrup is generally well tolerated. Possible side effects include:
- Common: Headache, dry mouth, fatigue
- Rare: Dizziness, gastrointestinal discomfort, increased heart rate
Latest Information
Recent clinical studies confirm the continued efficacy and safety of AERIUS Syrup in treating allergic rhinitis and urticaria. Ongoing research explores its potential role in additional allergic conditions.
Conclusion
AERIUS Syrup is a highly effective, non-sedating antihistamine for treating allergic rhinitis and urticaria. With once-daily dosing and proven safety in children and adults, it provides long-lasting relief from allergy symptoms. Always consult a healthcare professional before use.
