Intended Use
Alzair Allergy Blocker is intended to treat hay fever and allergy sufferers by promoting alleviation of mild allergic symptoms (i.e. mild nasal irritation including itchy, runny, or congested nasal passages) triggered by the inhalation of various airbone allergens including indoor environmental pollens, house dust, animal hairs and dust mites. Application of nasal ease produces a mucous-like gel barrier that evenly coats the nasal membranes and acts to block inhaled allergens within the nasal cavity.
Device Description
Alzair Allergy Blocker is composed of pharmaceutical grade Hydroxypropyl Methylcellulose (HPMC; 98.5%) and high quality peppermint (1.5%) which has been formulated into a micronized powder of fine particles of inert cellulose. Alzair Allergy Blocker is administered by insufflation into the nose using a proprietary spray bottle which enables the powder to be applied evenly as a fine mist to the inside of the nasal cavity. When Alzair Allergy Blocker powder comes into contact with the moist surface of the nasal mucosa, it almost immediately forms a colorless, mucus-like fine gel which coats the inside of the nasal cavity. The inert gel acts as a mechanical barrier -- making it more difficult for inhaled allergens to come into contact with the skin in the nasal interior, and thus reducing the intensity of allergic rhinitis symptoms.

No
The device description and intended use focus on a mechanical barrier created by a powder that forms a gel, with no mention of AI or ML technology.

Yes.
The device is intended to alleviate mild allergic symptoms by acting as a barrier to inhaled allergens, which classifies it as having a therapeutic effect.

No

Explanation: The device is intended to treat symptoms of allergies by forming a physical barrier in the nasal cavity, not to diagnose medical conditions or identify the presence of allergens.

No

The device description clearly states it is a powder composed of HPMC and peppermint, administered via a spray bottle, which forms a gel barrier. This is a physical substance and delivery mechanism, not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to "treat hay fever and allergy sufferers by promoting alleviation of mild allergic symptoms... triggered by the inhalation of various airborne allergens". This describes a therapeutic or preventative action within the body, not a diagnostic test performed on a sample taken from the body.
  • Mechanism of Action: The device works by forming a physical barrier (a gel) within the nasal cavity to block allergens from contacting the nasal membranes. This is a mechanical action, not a chemical or biological reaction used to detect or measure something in a sample.
  • Device Description: The description focuses on the composition of the powder and how it forms a gel barrier. There is no mention of reagents, assays, or any components typically associated with in vitro diagnostic tests.
  • Lack of Diagnostic Language: The document uses terms like "treat," "alleviation," "block," and "reduce symptoms," which are indicative of a therapeutic device, not a diagnostic one.

In vitro diagnostics are tests performed on samples (like blood, urine, tissue) taken from the body to detect diseases, conditions, or infections. This device acts directly within the body to prevent the effects of allergens.

K132520 -- Allergy Blocker, Nasal Eze International (31-DEC-14)

Basis for Submission

The changes to the product are the addition of the Prescription Use identifier in the labeling and the new brand for US marketing, "Alzair Allergy Blocker".

Product Description

Alzair Allergy Blocker is composed of pharmaceutical grade Hydroxypropyl Methylcellulose (HPMC; 98.5%) and high quality peppermint (1.5%) which has been formulated into a micronized powder of fine particles of inert cellulose. Alzair Allergy Blocker is administered by insufflation into the nose using a proprietary spray bottle which enables the powder to be applied evenly as a fine mist to the inside of the nasal cavity.

When Alzair Allergy Blocker powder comes into contact with the moist surface of the nasal mucosa, it almost immediately forms a colorless, mucus-like fine gel which coats the inside of the nasal cavity. The inert gel acts as a mechanical barrier -- making it more difficult for inhaled allergens to come into contact with the skin in the nasal interior, and thus reducing the intensity of allergic rhinitis symptoms.

Indications for Use

Alzair Allergy Blocker is intended to treat hay fever and allergy sufferers by promoting alleviation of mild allergic symptoms (i.e., mild nasal irritation including itchy, runny, or congested nasal passages) triggered by the inhalation of various airborne allergens including indoor and outdoor environmental pollens, house dust, animal hairs, and dust mites.

Application of Alzair Allergy Blocker produces a mucous-like gel barrier that evenly coats the nasal membranes and acts to block inhaled allergens within the nasal cavity.

Safety Testing & Toxicology

HPMC and spearmint are recognized as GRAS in the US. Overall, HPMC is a remarkably safe material when given orally in gram quantities. The quantity, grade, and route of administration of HPMC used in Alzair Allergy Blocker do not present any serious toxicological risks.

Combining HPMC with Mint flavoring is most unlikely to cause any toxicological hazards as all the ingredients are rated non-hazardous and the quantities ingested are well below any known recommended unconditional daily acceptance level.

Biocompatibility

Biocompatibility testing included cytotoxicity, sensitization, and irritation. The results demonstrated that there are no biocompatibility concerns with Alzair Allergy Blocker.

Stability and Shelf Life

Stability and shelf life testing results support a shelf life of at least 3 yrs at 40°C. Once the bottle is opened, labeling directs the consumer to use the product within 6 months.

History of Safe and Effective Use

The predicate, Nasaleze Allergy Blocker (which has an identical formulation), has been registered as a Class I Medical Device with MHRA since 1991 and is currently sold in more than 50 countries worldwide. During this +25 year period, there have been no reports of any serious adverse events attributed to Nasaleze by consumers who have safely used over 7,000,000 products sold.

Conclusions

By virtue of its physical characteristics, intended use, and performance testing, Alzair Allergy Blocker (K170848) is equivalent to Nasaleze Allergy Blocker (K132520).

Alzair Allergy Blocker poses no safety risk to users, and has been shown to significantly block allergen entry into the nasal mucosa. Clinical studies have demonstrated that the allergy blocker's mucous-like gel barrier is beneficial to hay fever sufferers through the reduction of nasal allergen exposure and consequently a reduction in symptoms from seasonal allergic rhinitis.
