Clinical Trials

Objective and test group: Prior to the release of Medinose, red light phototherapy was clinically assessed in a double-blind randomized study. Groups of people suffering from both allergic rhinitis and nasal polyps were tested to see if their conditions could be helped by low-energy narrow-band red light phototherapy.

How the trials were conducted: 50 patients with allergic rhinitis and 10 with nasal polyposis received intranasal illumination at 660 nm for 4.4 minutes three times a day for 14 day. Meanwhile, 29 rhinitic patients and 1 patient with polyposis received equivalent sham illumination as placebo. Evaluation was based on how far symptoms had improved, and on clinical assessments before and after the tests.

Results of trials: 72% of the allergic rhinitis patients reported an improvement in symptoms following the trial. Also a medical improvement was endoscopically seen in 70% of them. In comparison, 24% in the placebo group reported an improvement in symptoms,  and 3% were seen to have visible medical improvements during examination. However, the phototherapy did not work for patients with polyposis, where no change was seen to the condition.

Conclusion: allergic rhinitis patients saw significant improvements to their symptoms, whereas patients with sinusitis or polyps did not. Therefore the treatment can be very effective for allergy sufferers but not for those with polyposis.
