Background: Allergic rhinitis (AR) is an immune response of the nasal mucosa to airborne allergens and involves nasal congestion, watery nasal discharge, itching of the nose and sneezing. The symptoms of allergic rhinitis may significantly affect a patient’s quality of life and can be associated with conditions such as fatigue, headache, cognitive impairment and sleep disturbances. Various complementary and alternative medicine treatments have been used for this condition in clinical practice. The Ayurveda system of medicine is the most common complementary medicine system practiced in Sri Lanka. The aim of this study is to examine the efficacy and safety of a decoction used in traditional Ayurveda for allergic rhinitis and it’s ready to use freeze dried formulation in comparison to an antihistamine over a period of 4 weeks on relief of symptoms in allergic rhinitis. Study design: This is a three arm, open label, non-inferiority, randomized controlled clinical trial enrolling patients with AR. Tamalakyadi decoction containing 12 ingredients (TMD12), used in traditional Ayurveda and its freeze dried formulation are the test products. The efficacy and safety of the two Ayurvedic dosage forms will be tested against the antihistamine loratidine Patients with symptoms of AR will be allocated randomly into the 3 arms after a 1 week run-in period and the medications will be given orally for 28 days. Total Nasal symptom Score (TNSS) of the patients will be used as the primary efficacy endpoint. TNSS will be recorded and compared between the 3 arms prior to visit 1, at the end of 28 days, end of the and second months of follow up. Symptom scores of daytime nasal symptoms, night time nasal symptoms, non-nasal symptoms and Health Related Quality of Life questionnaire are used as secondary end points. Discussion: This clinical trial will be able to provide evidence based scientific data on Ayurvedic dosage form, TMD12 and the freeze-dried formulation in the treatment of allergic rhinitis. This trial is expected to develop capacity to scientifically evaluate various Ayurvedic treatments that are claimed to have efficacy in treatment of various disease conditions.

Background Allergic rhinitis (AR) is an immune response of the nasal mucosa to airborne allergens and involves nasal congestion, watery nasal discharge, itching of the nose and sneezing. The symptoms of allergic rhinitis may significantly affect a patient’s quality of life and can be associated with conditions such as fatigue, headache, cognitive impairment and sleep disturbances. Various complementary and alternative medicine treatments have been used for this condition in clinical practice. The Ayurveda system of medicine is the most common complementary medicine system in Sri Lanka. The aim of this study is to find out whether the use of two preparations (decoction and its freeze dried powder) over a period of 4 weeks is able to cure the symptoms of allergic rhinitis. Study design This is a three arm open label non-inferiority randomized controlled clinical trial in patients with AR. The study duration is 28 days oral administration of the two Ayurvedic dosage forms (Decoction and freeze dried) and the antihistamine loratidine into the 3 arms allocated randomly. After a 1 week run-in period, eligible subjects are randomly assigned to the TMD12 decoction group, TMD12 freeze dried group and the antihistamine group. Total Nasal symptom Score (TNSS) of the patients are used as the primary efficacy outcome. TNSS is recorded and compared in all 3 arms prior to visit 1, at the end of 28 days, end of the first month of follow up and second month of follow up. Symptom scores of daytime nasal symptoms, night time nasal symptoms, non-nasal symptoms and Health Related Quality of Life questionnaire are used as secondary end points. Discussion This clinical trial will be able to provide supportive evidence based scientific data on classical Ayurvedic dosage forms and the new dosage forms developed as freeze dried powder in the treatment of allergic rhinitis. Also by this trial, it is expected to develop capacity to scientifically evaluate Ayurvedic treatments that may help patients having conditions such as allergic rhinitis.
