Treatment of rhinitis and respiratory symptoms induce by allergens from pollution


Introducing ALLERPUR, a pioneering solution by Vitrobio for individuals suffering from rhinitis and respiratory symptoms triggered by environmental pollutants. This nasal spray comes in a convenient 15ml bottle, designed for effortless application and optimal delivery of its active ingredients to combat the effects of pollution-induced allergies.

Mode of action

ALLERPUR stands out with its triple-action formula that not only provides immediate relief but also offers a long-term solution to pollution-induced allergic reactions.

  • Protective Barrier: Creates a filmogenic liquid bandage on the nasal mucosa to shield against allergens, impurities, and harmful heavy metals while soothing and hydrating the irritated areas.
  • Mechanical Cleaning: High osmotic action draws in and traps contaminants, including allergens and heavy metals, reducing inflammation and preventing the progression of allergic responses.
  • Cellular Repair: Promotes the healing and regeneration of the nasal mucosa, restoring its natural barrier against future allergic triggers.

Clinical Evidence of Efficacy

The effectiveness of ALLERPUR has been proven in a randomized, double-blind, placebo-controlled trial, showing a significant reduction in both nasal and ocular symptoms of allergies caused by environmental pollution. Notably, the trial demonstrated a 79% reduction in total nasal symptoms over three weeks, without any reported side effects.


  • Total nasal symptoms reduced by 36% within 6 days, reaching 79% by the third week.
  • Total ocular symptoms saw a reduction of up to 60% by the third week.
  • Showcased a 41% improvement in the Rhinoconjunctivitis Quality of Life Questionnaire scores.
