Sinus Buster

In early 2010, Sinus Buster was evaluated in a double-blind study. The study was designed to evaluate the effectiveness and safety of Sinus Buster for the treatment of sinus and nasal congestion in patients suffering from non-allergic rhinitis. The study included 42 subjects and measured the improvement in nasal congestion, sinus pressure, and headache over 2 weeks. It also evaluated speed of action and key safety parameters. The study showed that subjects who received Sinus Buster experienced onset of relief in under one minute per a stopwatch assessment (average of 52 seconds). Sinus Buster subjects showed a statistically significant improvement over the placebo in nasal congestion, sinus pressure and headache at each of the measured time points after first use (5, 10, 15, 30, 60 minutes). The study also showed Sinus Buster to have a favorable safety profile. There was no negative effect on sense of smell or indication of rebound effect. Although this pilot trial was small, Bernstein et al. concluded that Sinus Buster works quickly to effectively treat chronic rhinitis patients with a significant non-allergic component, and is safe to use continuously over 2 weeks. Additional clinical trials are needed to confirm these findings in a larger patient population.

Capsaicin

Capsaicin-based nasal sprays have been tested clinically for over 10 years. Key clinical findings are summarized below, as they relate to the use of capsaicin as a treatment option for sinusitis, allergic rhinitis

Rhinitis

It is caused by chronic or acute inflammation of the mucous membrane of the nose due to viruses, bacteria or...

, and cluster headaches:

1. In another study of hyperreactive rhinopathy with 84 patients, intranasal capsaicin was used for four weeks and resulted in marked reductions of symptoms without significant side effects in the majority of patients.
2. In a study of 50 patients with perennial allergic rhinitis, topical, nasal capsaicin was shown to reduce Substance P content in nasal secretions by 43% (with statistical significance) and to result in a total effective rate of 94%.
3. When studied as a treatment for cluster headache, nasal applications of capsaicin resulted in symptom amelioration in 70% of those patients who applied the drug on the same side as their cluster headache.
4. In a study treating non-allergic non-infectious perennial rhinitis, intranasal capsaicin spray caused significant and long-term (up to 9 months post-therapy) reductions in overall nasal symptoms, rhinorrhea and nasal blockage. No significant changes in safety (smell, blood pressure, heart rate) were seen.
5. In a placebo-controlled study of 25 patients with non-allergic non-infectious perennial rhinitis, intranasal capsaicin was shown to have no significant impact on inflammatory markers (leukotriene (LT) C4/D4/E4, prostaglandin D2 (PGD2), and tryptase) in the nasal mucosa.
6. When used to treat non-allergic non-infectious perennial rhinitis, capsaicin aqueous nasal spray reduced nasal complaints without affecting cellular homeostasis or overall neurogenic staining up to 9 months after treatment.
7. When used to treat allergic rhinitis, nasally-applied capsaicin provided symptom relief, and resulted in a statistically-significant 35% reduction in nasal airflow resistance. At one-year follow-up, the total effective rate was 89%.
8. In a 2-year study treating cluster headache, capsaicin applied to the nasal mucosa resulted in consistent therapeutic effects.
