AERIUS 0.5mg/ml Solution (Oral)

What is AERIUS 0.5mg/ml

AERIUS 0.5mg/ml is an oral solution formulation of Desloratadine, an antihistamine used to treat allergic conditions. Desloratadine is a second-generation H₁-receptor antagonist known for its effectiveness in relieving symptoms associated with allergic rhinitis (hay fever) and chronic idiopathic urticaria (chronic hives).

• Active ingredient: Desloratadine at 0.5 mg per ml, designed for flexible dosing especially in pediatric and elderly patients.
• Indications: Used for symptomatic relief of nasal and non-nasal allergy symptoms such as sneezing, runny nose, itchy and watery eyes, and skin itching or hives.
• Oral solution form: Offers an alternative to tablets for patients who have difficulty swallowing pills, such as children or elderly individuals.
• Non-sedating: Being a second-generation antihistamine, AERIUS has minimal penetration into the central nervous system, reducing drowsiness compared to first-generation antihistamines.
• Onset and duration: Begins working within 1 to 3 hours after administration with effects lasting up to 24 hours, allowing once-daily dosing.

Overall, AERIUS 0.5mg/ml oral solution is a convenient and effective option for managing allergy symptoms in a wide range of patients.

How to use AERIUS 0.5mg/ml

Proper administration of AERIUS 0.5mg/ml oral solution is important to ensure effectiveness and safety:

• Dosage measurement: Use the provided measuring device or a calibrated oral syringe to ensure accurate dosing.
• Typical dosing: Follow your healthcare provider’s recommendations. For adults and children aged 12 years and above, the usual dose is 5 ml (2.5 mg) once daily.
• Pediatric dosing: For children aged 6 to 11 years, typically 2.5 ml (1.25 mg) once daily; younger children dosing depends on physician advice.
• Administration: The solution can be taken with or without food.
• Timing: Preferably take at the same time each day to maintain consistent blood levels.
• Missed dose: If a dose is missed, take it as soon as remembered unless it is near the time of the next dose. Do not double doses to compensate.
• Duration of treatment: Use for the duration prescribed; do not stop treatment abruptly unless advised by a healthcare provider.
• Consultation: Inform your healthcare provider about all medications and health conditions before starting.

Correct use helps achieve optimal symptom control with minimal risk of side effects.

Mode of Action AERIUS 0.5mg/ml

AERIUS contains desloratadine, which acts specifically on histamine H₁ receptors to reduce allergic symptoms:

• Histamine antagonist: Desloratadine selectively blocks peripheral H₁-receptors, preventing histamine from binding and triggering allergic reactions.
• Reduction of symptoms: By inhibiting histamine’s effects, it reduces typical allergic manifestations such as itching, sneezing, runny nose, and hives.
• Non-sedating profile: Limited penetration across the blood-brain barrier means it does not cause significant sedation or drowsiness, unlike first-generation antihistamines.
• Anti-inflammatory effects: Desloratadine also modulates release of other inflammatory mediators, providing additional relief beyond histamine blockade.
• Pharmacokinetics: After oral administration, desloratadine is rapidly absorbed, reaching peak plasma levels in about 3 hours, with a half-life of approximately 27 hours, supporting once-daily dosing.

Through these mechanisms, AERIUS efficiently manages allergic symptoms with a favorable safety profile.

AERIUS 0.5mg/ml Interactions AERIUS 0.5mg/ml

Although AERIUS generally has a low potential for drug interactions, certain medications and substances can affect its efficacy or safety:

• CYP3A4 and CYP2D6 inhibitors: Desloratadine is metabolized by these liver enzymes. Potent inhibitors such as ketoconazole, erythromycin, or cimetidine may increase desloratadine levels slightly, though clinically significant interactions are rare.
• Other antihistamines: Concurrent use with other antihistamines is generally not recommended, as it may increase risk of side effects.
• Alcohol and CNS depressants: Though desloratadine is non-sedating, combining it with alcohol or sedatives might increase drowsiness in sensitive individuals.
• Ritonavir and other antiviral agents: May increase desloratadine plasma concentrations, necessitating caution or dose adjustment.
• Monoamine oxidase inhibitors (MAOIs): No significant interactions expected, but caution advised with other drugs affecting the central nervous system.
• Always consult your healthcare provider: Disclose all medications, supplements, or herbal products you are taking to avoid potential interactions.

Overall, AERIUS is considered safe with minimal interaction risks when used as directed.

Dosage of AERIUS 0.5mg/ml

Correct dosing of AERIUS oral solution depends on the patient's age and medical condition:

• Adults and adolescents (≥12 years): 5 ml (2.5 mg desloratadine) once daily is the standard dose.
• Children aged 6 to 11 years: Typically 2.5 ml (1.25 mg) once daily.
• Children under 6 years: Safety and efficacy not fully established; use only under medical supervision.
