A Herbal Formula in the Therapy of Acute Postviral Rhinosinusitis

OBJECTIVE: To assess the effects and adverse events of preparation Sinulan forte(®) containing extracts of five medicinal plants in comparison to mometasone furoate nasal spray (MFNS) in therapy of acute postviral rhinosinusitis (APRS). METHODS: We included 46 APRS patients in this prospective investigation and randomized to two groups. The patients in group 1 (n=23) received MFNS 200 μg two times/day for ten days, and patients in group 2 (n=23) received Sinulan forte(®), tablets 225 mg per os, two times/day also for ten days. We evaluated the total symptom score (TSS), the separate scores for individual symptoms (nasal congestion, rhinorrhea, postnasal discharge, facial pain, impaired sense of smell), the quality-of-life outcome, and the findings from nasal endoscopy (edema of the nasal mucosa, nasal secretion) prior and after the therapy. RESULTS: Significantly lower absolute post-treatment scores and better relative improvement were identified for TSS, nasal congestion, facial pain, loss of the sense of smell, edema of the mucosa and nasal secretion in patients receiving herbal preparation (group 2). However, lower absolute post-treatment score and better relative improvement were found for rhinorrhea and postnasal drip in group 1. Clinically important differences were found regarding the TSS and endoscopic findings, with no adverse effects in group 2, but in group 1 two patients had mild nasal bleeding and two had sensation of dryness in the nasal mucosa. CONCLUSION: Herbal product Sinulan forte(®) can be a safe and effective treatment for APRS. Our results suggest no adverse events of this herbal preparation in comparison to intranasal corticosteroid spray therapy.
