Summary
Brief summary
Hypothesis: Larri Oral spray will have symptomatic benefit as measured by the RSI questionnaire.

Method: 80 patients will be recruited from our ENT clinics at a tertiary centre in Monash Health. Patients will need to be clinically diagnosed to have laryngopharyngeal reflux by their laryngologist and then test positive on a salivary pepsin test to be included. They will then be recruited and randomised into either receiving Larri Oral Spray or a Placebo spray for eight weeks. Prior to commencing their therapy, a baseline Symptom questionnaire will be taken, and then after eight weeks this will then be repeated. Patients already on anti-reflux medication will be allowed to continue their medication
