[Pharmacology of Sinupret. Recent results on the rational for the Sinupret compound].

The herbal medicinal product Sinupret has been successfully used for the treatment of sinusitis for 70 years. In Germany the product is established as a standard in the therapy of sinusitis. The most recent pharmacodynamic findings resulted from close scientific cooperation with Pontus Stierna and co-workers from the Karolinska Institute in Stockholm: Mice were infected intranasally with Streptococcus pneumoniae to induce bacterial rhinosinusitis. Animals were randomized to treatment with ampicillin, dexamethasone, Sinupret, or sham treatment. All groups receiving active treatment showed a reduction in bacterial growth after 4 days and a significant reduction of bacterial growth after 8 days. Similar results were observed regarding histopathology. Initial findings in a sinusitis model in the New Zealand White rabbit confirmed the results observed in the aforementioned studies in mice. Understanding of the pharmacological profile of Sinupret supports the knowledge about the clinical efficacy of this herbal medicinal product.
