Generic Azelastine

Introduction

Azelastine is a prescription-only antihistamine formulated as a nasal spray (10 ml bottle) for adult patients. It belongs to the second-generation antihistamine class and is primarily indicated for relief of seasonal and perennial allergic rhinitis. The medication is available in a convenient sprayer device that delivers a measured dose to the nasal mucosa. In some regions it is marketed under brand names such as Astepro and Allergodil. Azelastine can also be used to treat allergic conjunctivitis when formulated as an eye-drop, but the focus of this article is the nasal spray preparation.

What is Azelastine?

Azelastine is the active pharmaceutical ingredient (API) in several branded nasal sprays for allergic rhinitis. It was first introduced in the early 1990s by Meda AG (now part of Mylan) and later licensed to various manufacturers worldwide. The drug is classified as a second-generation H₁-receptor antagonist; unlike first-generation antihistamines, it has limited ability to cross the blood-brain barrier, reducing sedation.

Azelastine is the generic version of well-known medications, containing the active compound azelastine hydrochloride. Our online pharmacy provides this generic alternative as a cost-effective treatment option.

How Azelastine Works

Azelastine blocks histamine H₁ receptors on nasal epithelial cells. Histamine, released during an allergic response, binds to these receptors and triggers symptoms such as itching, sneezing, rhinorrhea, and congestion. By competitively inhibiting the receptor, azelastine prevents histamine-mediated signaling.

In addition to antihistamine activity, azelastine exhibits mast-cell stabilizing properties, reducing the release of other inflammatory mediators (leukotrienes, prostaglandins). The combined actions lead to rapid symptom relief, typically within 5-15 minutes, and a duration of effect lasting up to 12 hours. Systemic absorption after nasal administration is minimal (≈2 % of the dose), contributing to a favorable safety profile.

Conditions Treated with Azelastine

• Seasonal allergic rhinitis (hay fever): Triggered by pollen, azelastine alleviates sneezing, itching, and nasal discharge.
• Perennial allergic rhinitis: Effective for year-round allergy symptoms caused by dust mites, animal dander, or molds.

The drug is valuable because it targets the primary pathogenic pathway (histamine release) while also limiting secondary inflammation, offering both quick relief and sustained control.

Off-Label and Investigational Uses of Azelastine

• Non-allergic rhinitis: Small open-label studies have reported improvement in vasomotor rhinitis symptoms, suggesting a possible role for azelastine’s anti-inflammatory effects. This use is not approved by the FDA or EMA.
• Mild chronic sinusitis: Limited case series indicate that adjunctive azelastine nasal spray can reduce mucosal edema, but robust trial data are lacking.
• Allergic ocular disease (as eye-drops): While the eye-drop formulation is approved, some clinicians compound the nasal spray for off-label ocular use. This practice must be overseen by an ophthalmologist.

Important: Off-label applications have not undergone the rigorous evaluation required for official approval. Patients should discuss any such use with a qualified healthcare provider before initiation.

Is Azelastine the Right Medication for You?

Azelastine is most suitable for adults who experience moderate-to-severe nasal allergy symptoms that are inadequately controlled by oral antihistamines or avoidance measures. It is especially advantageous for individuals who:

• Require rapid symptom relief without drowsiness.
• Prefer a locally acting medication that minimizes systemic exposure.

Contraindications include known hypersensitivity to azelastine or any excipients in the spray, and severe nasal obstruction that prevents proper spray delivery. Use with caution in patients with a history of paradoxical bronchospasm or those using monoamine-oxidase inhibitors (MAOIs), as a theoretical interaction exists though it is rare.

Risks, Side Effects, and Interactions

Common

• Nasal irritation or burning sensation
• Unpleasant taste (post-nasal drip)
• Mild headache

Rare

• Epistaxis (nosebleed)
• Transient dysgeusia (altered taste)

Serious

• Hypersensitivity reactions (urticaria, angioedema, anaphylaxis)
• Severe nasal ulceration (very uncommon)

Drug-Drug Interactions

• MAO inhibitors: May increase plasma levels of azelastine; monitor for excessive sedation or antihistaminic effects.
• CYP2D6 substrates (e.g., certain antidepressants): Azelastine is metabolized in part by CYP2D6; co-administration may modestly raise azelastine concentrations.

Drug-Food Interactions

• No significant food interactions have been identified. Alcohol does not potentiate sedation with azelastine, but excessive intake may worsen nasal congestion.

Patients should avoid inserting objects into the nostrils and should not share the spray device to prevent contamination.

Use: Dosing, Missed Dose, Overdose

The usual adult dosing is one spray (approximately 137 µg azelastine) in each nostril twice daily (approximately 12-hour interval). Some clinicians may increase to three sprays per nostril per day for severe cases, but this should be directed by a prescriber.

• 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-dose.
• Overdose: Signs of excessive azelastine exposure include pronounced drowsiness, severe headache, or cardiac palpitations. In suspected overdose, seek immediate medical attention; supportive care is the mainstay of treatment.

Practical precautions:

• Do not use the spray immediately after consuming alcohol or while operating heavy machinery until you know how azelastine affects you.
• Store the bottle at room temperature, protected from excessive heat or humidity.
• Keep the spray upright; avoid freezing temperatures which may alter the formulation.

FAQ

• What is the best way to store a 10 ml azelastine nasal spray? The spray should be kept at a controlled room temperature (15-30 °C) away from direct sunlight and moisture. Do not refrigerate or freeze, as extreme temperatures can change the viscosity and spray pattern.

• Can I travel internationally with azelastine nasal spray in my carry-on luggage? Yes. The 10 ml bottle complies with most airline liquid restrictions when placed in a transparent, resealable bag. Carry the prescription label or a copy of the medication information sheet to avoid customs delays.

• Are there any excipients in the azelastine spray that might cause allergic reactions? The formulation contains benzalkonium chloride (a preservative) and sorbitol. Patients with known sensitivities to these ingredients should discuss alternatives with a healthcare professional.

• How does azelastine compare with oral antihistamines for allergic rhinitis? Azelastine provides targeted nasal relief with a rapid onset and minimal systemic sedation, whereas oral antihistamines affect the whole body and may cause drowsiness. For persistent nasal congestion, the nasal spray is often more effective.

• Is it safe to use azelastine while pregnant or breastfeeding? Current data are limited; the medication is classified as Pregnancy Category B in the United States, indicating no evidence of risk in animal studies but insufficient human data. Breastfeeding mothers should weigh potential benefits against unknown infant exposure.

• Can I use azelastine nasal spray together with a nasal steroid spray? Yes. Combining azelastine with intranasal corticosteroids (e.g., fluticasone) is a common strategy for severe allergic rhinitis, providing additive anti-inflammatory effects. Administer each spray in separate nostrils or wait at least 5 minutes between applications.

• What should I do if the spray nozzle becomes clogged? Gently clear the tip with a clean tissue or run the spray under warm water for a few seconds, then test the device. Do not use sharp objects that could damage the nozzle.

• Does azelastine have any effect on the sense of smell? By reducing nasal inflammation, azelastine may improve olfactory function in patients whose smell loss is allergy-related. However, it does not directly stimulate the olfactory nerves.

• Are there differences between azelastine formulations sold in different countries? The active ingredient concentration (137 µg per spray) is consistent worldwide, but preservatives, propellants, and packaging may vary to meet local regulatory standards.

• What is the environmental impact of the azelastine spray packaging? The plastic bottle is recyclable in most municipal programs. The propellant used is a hydrofluoroalkane (HFA) with a lower ozone-depleting potential than earlier chlorofluorocarbon (CFC) propellants.
