Cleanoze® Irrigation Device With Powder Preparation Versus Conventional Irrigation Method for Chronic Rhinitis

Phase III Randomized Open-label Clinical Trial Comparing Cleanoze® Irrigation Device With Powder Preparation Versus Conventional Irrigation Method for Chronic Rhinitis

The investigators proposed that the Cleanoze® is superior to the traditional nasal saline irrigation in term of the ease of use which will resulting in a better quality of life of the participants. This study will compared the efficacy, adverse reactions, complications and ease of use of Cleanoze® comparing with normal saline solution

Cleanoze® consists of a powder made up of Sodium chloride and Sodium Bicarbonate. This powder when dissolved in 250 ml of water is closely resembles the content of a body fluid which normally baths the outside of the cells of the body. This fluid is isotonic solution.

The nasal saline irrigation is the common procedure for upper respiratory tract infection patients including chronic rhinitis. The physician usually order the normal saline with appropriate medication e.g. anti-histamines, nasal steroids and anti-biotics to treat this condition.

The investigators proposed that the Cleanoze® is superior to the traditional nasal saline irrigation in term of the ease of use which will resulting in a better quality of life of the participants. This study will compared the efficacy, adverse reactions, complications and ease of use of Cleanoze® comparing with normal saline solution.

Study Population: Any patients with chronic rhinitis (e.g. allergic rhinitis, vasomotor rhinitis) will be randomized to receive the study or control medication. The investigators will include the children 5 years and above which able to doing the lavage under the parents assistant or by them self.
