Placebo-controlled, randomized double-blind clinical trial with Sinupret® sugar coated tablets on the basis of a therapy with antibiotics and decongestant nasal drops in acute sinusitis.

On the basis of therapy with antibiotics and nasal decongestants the efficacy of an additional treatment with the herbal combination Sinupret containing gentian root, cowslip flowers, sour dock herbs, elder flowers and shop vervain wort herbs was assessed in a randomized, placebo-controlled double-blind clinical trial involving 160 patients with acute bacterial sinusitis. Primary outcome criteria were radiographic findings and patient assessment. Secondary variables were several clinical symptoms of sinusitis which served as indicators of the pharmacological profile. The results showed that, according to the radiographic findings and the patient assessments, therapy with antibiotic and decongestants achieved a significant improvement in the treatment group; changes in clinical signs showed good correlation with the radiographic findings and the patient assessments. Conventional therapy for acute bacterial sinusitis can be improved markedly by including Sinupret in the therapeutic regimen.
