Brief Summary:
The purpose of this study is to demonstrate the equivalence of two homeopathic capsaicin containing nasal sprays (Sinol-M™ and Sinol) in patients with nasal congestion due to allergic rhinitis.

Condition or disease Intervention/treatment Phase
Allergic Rhinitis Drug: Sinol or Sinol-M nasal spray Phase 4

Detailed Description:

Sinol is an FDA registered, capsaicin-based, over-the-counter homeopathic nasal spray used for the relief of allergy and sinus conditions. It is an all-natural product that the patient uses on an as-needed basis for up to 12 times daily.

Sinol has been available in the US since 2004. In 2009 a second generation product, Sinol-M will be launched. Sinol-M is identical to the original formula but also contains MucoAd MucoAd™ is a patented non-toxic, non-irritating, liquid polymer mucoadhesive carrier that prolongs the contact time between drug and mucosa, thus increasing bioavailability. It can be loaded with nearly any pharmaceutical preparation and delivered a variety of mucosal tissues. Reduced mucociliary clearance of intranasally-applied drugs is desirable to reduce the naturally-occurring washing out of topically applied medications.

The objective of the current Phase IV, randomized, double-blind, cross-over study, was to evaluate the frequency of use and efficacy of SINOL and SINOL + MucoAd™ (Sinol-M) and to demonstrate non-inferiority of Sinol-M versus the existing product Sinol.

Additionally, as most homeopathic drugs are not supported by prospective clinical data there is a belief among many mainstream healthcare practitioners, and some consumers that these products do not work. This study therefore provides an opportunity to demonstrate improved efficacy versus no treatment (during the run-in and washout phases).
