About

This randomized, double-blind, parallel group, placebo-controlled study assessed subjective measures of nasal airway breathing immediately after application in the morning upon awakening after use of breathe right nasal strips (BRNS). Participants who met the entrance criteria, were currently suffering from nasal congestion, reported trouble with their sleep and had baseline nasal openness scores at bedtime during the qualification phase of ≤ 70 on a 100-point Visual Analogue Scale (VAS) on at least four of seven qualification nights were randomized to one of two treatments for use at home. Participants returned to the study site after 7 and 14 days of nightly nasal strip use, respectively. At the two return visits, a validated subjective questionnaire, the Nocturnal Rhinoconjunctivitis Quality of Life Questionnaire (NRQLQ), measured response.

Full description

The study had a screening phase, a one-week baseline qualification and a two-week treatment phase. Participants who met the entrance criteria, who were currently suffering from nasal congestion every night or almost every night, reported trouble with their sleep and had baseline nasal openness scores at bedtime during the qualification phase of ≤ 70 on a 100-point VAS on at least four of seven qualification nights were randomized to one of two treatments for use at home. During the two-week in-home treatment phase, daily diaries measuring the perception of nasal breathing and nasal congestion using a VAS were completed. Participants returned to the study site after 7 and 14 days of nightly nasal strip use, respectively. At the two return visits, a validated subjective questionnaire, the NRQLQ, measured response.

• Participant plans travel involving time-zone changes during the study period.

• Regular/habitual consumption of more than five cups or glasses per day of xanthine-containing beverages (i.e. tea, coffee, cola).

• Participant currently uses any product or medication that has an effect on nasal congestion or sleep. Participant must have discontinued use of the following products according to the timings specified below:

Use of over-the-counter (OTC) sleep promoting agents including diphenhydramine, doxylamine, tryptophan, valerian root, kava kava, melatonin, St John's Wort and Alluna. Use of OTC alertness aids including caffeine and guarana.

ii. Lubricating sprays/rinses/throat strips iii. Devices prescribed or used for sleep disordered breathing including Continuous Positive Airway Pressure (CPAP), mandibular advancement devices, tongue displacement devices iv. Use of any intranasally administered medications (e.g. Miacalcin) b) Within 3 days prior to the initiation of the baseline qualification phase: i. Oral decongestants ii. Short-acting prescription and non-prescription antihistamines, including ocular preparations and antihistamines contained in OTC sleep medications or 'night time' pain formulations (e.g. Benadryl, Chlortrimeton, Dimetane, Tavist) iii.
