Generic Astelin Information

Introduction

Astelin is a nasal spray containing the antihistamine azelastine hydrochloride. It is classified within the allergy medication group and is designed to relieve symptoms of allergic rhinitis such as sneezing, nasal itching, rhinorrhoea, and congestion. The product is marketed by Allergan (now part of AbbVie) and is registered for use throughout the United Kingdom. In addition to seasonal and perennial allergic rhinitis, Astelin may be prescribed for non‑allergic rhinopathy when an antihistamine effect is desired.

What is Astelin?

Astelin is a commercially available azelastine nasal spray. It belongs to the second‑generation antihistamines and is formulated as a metered‑dose spray delivering .1 % (1 mg/mL) azelastine hydrochloride. Development of azelastine dates to the early 199s, with Astelin gaining approval from the UK Medicines and Healthcare products Regulatory Agency (MHRA) for adult and paediatric use (≥12 years). The medication is supplied in a single‑use pump delivering a precise 140 µL dose per actuation.

Well‑known Azelastine‑related brand names include Astepro, Azigo, and Azelastine Hydrochloride. Our online pharmacy provides this generic alternative as a cost‑effective treatment option, adhering to the same quality standards as the original branded products.

How Astelin Works

Azelastine blocks histamine H1 receptors on the nasal mucosa, preventing the binding of endogenous histamine released during an allergic response. By antagonising H1 receptors, the drug reduces vasodilation, plasma‑exudation, and sensory nerve activation that underlie the classic symptoms of rhinitis.

Key pharmacologic points:

• Onset of action – Clinical improvement is often observed within 15 minutes of a single spray, reflecting rapid mucosal absorption.
• Duration – Symptom control persists for up to 12 hours, supporting twice‑daily dosing.
• Clearance – Azelastine is metabolised primarily by hepatic cytochrome P450 enzymes (CYP2D6, CYP3A4) and eliminated in urine as unchanged drug and glucuronide conjugates. The plasma half‑life is approximately 22 hours, but local nasal concentrations decline much faster, limiting systemic exposure.

Conditions Treated with Astelin

• Seasonal allergic rhinitis – Triggered by pollen, mould spores, or grass. In the UK, up to 20 % of adults experience seasonal symptoms, creating a substantial demand for rapid‑acting antihistamines.
• Perennial allergic rhinitis – Caused by house‑dust mite, animal dander, or cockroach allergens. Persistent exposure leads to chronic nasal irritation; azelastine provides ongoing control.
• Non‑allergic rhinitis – Certain forms of rhinitis, such as vasomotor or irritant‑induced, respond to antihistamine action despite the absence of an immunologic trigger.

Azelastine’s dual antihistamine and anti‑inflammatory properties (e.g., inhibition of mast‑cell degranulation) make it especially effective for these conditions, reducing both acute flare‑ups and baseline symptom burden.

Who is Astelin For?

• Adults and adolescents (≥12 years) with documented allergic or non‑allergic rhinitis.
• Patients requiring rapid symptom relief (e.g., during pollen season or after accidental exposure).
• Individuals preferring a nasal route over oral antihistamines, particularly those who experience systemic sedation with first‑generation agents.
• People with co‑existing asthma may benefit, as nasal inflammation often parallels lower‑airway hyperreactivity; however, Astelin does not replace inhaled therapy.

Contra‑indications – Astelin should be avoided in patients with known hypersensitivity to azelastine or any formulation component. Caution is advised for those with severe hepatic impairment, as metabolism may be altered. Pregnant or breastfeeding women should consult a healthcare professional before use.

Risks, Side Effects, and Interactions

Common

• Transient nasal irritation or burning – Usually mild and resolves within a few minutes.
• Taste distortion (metallic or bitter) – Result of post‑nasal drip of the spray.
• Sneezing – May occur as a reflex to the spray administration.

Rare

• Headache – Reported in <2 % of users, likely related to systemic absorption.
• Dry mouth or throat – Due to local antihistaminic effect on mucosal secretions.

Serious

• Severe hypersensitivity reactions – Including angio‑edema, urticaria, or anaphylaxis. Immediate medical attention is required.
• Persistent epistaxis – Uncommon but may indicate local mucosal injury.

Drug‑Drug Interactions

• CYP2D6 inhibitors (e.g., fluoxetine, quinidine) – May increase systemic azelastine concentrations; dose adjustment is rarely needed due to low systemic exposure, but vigilance is advised.
• Other intranasal medications – Concurrent use of decongestant sprays (e.g., oxymetazoline) can increase local irritation; spacing administrations by at least 30 minutes reduces risk.

Patients should disclose all concomitant medicines, including over‑the‑counter products and supplements, to a qualified healthcare provider.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dose – Two sprays (one per nostril) twice daily (approximately 280 µL total per administration).
• Pediatric dose (12‑17 years) – One spray per nostril twice daily, based on clinician guidance.

Missed dose – If a dose is forgotten, administer it as soon as remembered unless the next scheduled dose is within 2 hours; in that case, skip the missed dose and resume the regular schedule. Do not double the dose.

Overdose – In the unlikely event of excessive administration, symptomatic management is recommended. Most adverse effects are local and self‑limiting. Seek medical advice if severe systemic symptoms (e.g., dizziness, palpitations) develop.

Precautions –

• Avoid alcohol excess, which may modestly increase sedation.
• Store the spray at ambient temperature (15‑30 °C); do not refrigerate.
• Do not use the device if the nozzle is damaged or the spray appears discoloured.

• Can Astelin be administered to children younger than 12 years?
  The product is not licensed for use in children under 12 years. Clinical safety data for younger age groups are insufficient; a pediatric‑specific formulation should be considered.

• What are the legal requirements for personal import of Astelin into the UK?
  Under UK customs regulations, individuals may import a three‑month supply for personal use without a prescription, provided the product is correctly labelled and sourced from a licensed pharmacy.

• Does azelastine have any effect on drug testing for employment?
  Azelastine is not known to produce metabolites that trigger standard workplace drug screens. Its use should not affect routine testing outcomes.

• What historical milestones led to the development of azelastine?
  Azelastine was first synthesized in the 197s, with the first nasal spray (Astelin) receiving approval in the early 199s. Subsequent studies demonstrated its rapid antihistaminic action and low sedation profile, leading to widespread adoption for allergic rhinitis.

• How does Astelin compare with older first‑generation antihistamines used nasally?
  First‑generation agents often cause significant sedation and anticholinergic side effects. Astelin’s second‑generation profile offers comparable efficacy with minimal central nervous system penetration, resulting in a better safety and tolerability profile.

• Are there any known off‑label uses of azelastine nasal spray?
  Some clinicians report benefit in treating ocular allergic conjunctivitis via intranasal administration, exploiting the drug’s systemic absorption. This practice remains off‑label and should be considered only under specialist guidance.
