title: An open-label, in-use study assessing the warming sensation accompanying IFF Flavour 316282 and the acceptability and local tolerability of a syrup containing paracetamol and pseudoephedrine for the short-term treatment of symptoms of an upper respiratory tract infection.
abstract: OBJECTIVE
  The primary objective was to assess the warming sensation caused by IFF Flavour 316282 in a syrup used for short-term treatment by patients suffering from nasal congestion and mild to moderate body pain, headache, fever or sore throat associated with an upper respiratory tract infection.
  
  
  METHODS
  A single cohort, single treatment arm, open-label study. Subjects received one 30 mL dose of syrup containing IFF Flavour 316282, paracetamol and pseudoephedrine and recorded onset and disappearance of any warming sensation in the mouth/throat. Subjects' assessments of strength and appeal of the sensation, taste, texture and acceptability of the product was investigated using questionnaires.
  
  
  RESULTS
  A total of 56 subjects were included; 53 (94.6%) experienced a warming sensation. The median duration of the warming sensation was 114 s (95% confidence interval: 87-120 s). All subjects rated the syrup as excellent, good or fair for treating their symptoms; 100% and 94.6% of subjects respectively described texture and taste as excellent, good or fair. There were no safety concerns, and the syrup was well tolerated. Most subjects liked the warming sensation.
  
  
  CONCLUSIONS
  IFF Flavour 316282 in a syrup for treatment of upper respiratory tract infection symptoms is associated with a warming sensation. The syrup is well tolerated, safe and palatable.
