Efficacy and Safety of Oral Spray Containing Lysozyme and Cetylpyridinium: Subjective Determination of Patients with Tonsillopharyngitis

Tonsillopharyngitis (sore throat) is a common disease mainly related to the seasonal common cold. To relieve unpleasant symptoms and discomfort of acute tonsillopharyngitis associated with common cold, patients usually take some non-prescription drugs. The primary aim of this study was to assess subjective determinations of the efficacy and the safety/tolerability of an oral spray comprising a combination of lysozyme chloride and cetylpyridinium chloride in those patients. The study involved 1727 patients with tonsillopharyngitis associated with common cold and treated with the studied drug, in the period from December 2014 through March 2015. In total, 95% of patients rated the studied drug to be well, very well and excellently effective. In 32% of patients, the symptoms were relieved 10 minutes after the application of the spray. Significant correlations were found between the two subjective assessments of the drug efficiency with the total of 74.11% (95% CI: 73.41, 77.47%) of patients who said that the feeling of pain in the throat completely disappeared after the drug administration, evaluated the impact/effect of the drug was very good or good (Pearson Chi Square=391.401, p
