Abstract
AIMS
To compare two xylometazoline 0.1% preparations: reference commercial solution (RS) and test mucoadhesive solution (TS).
METHODS
Twenty subjects with perennial allergic rhinitis (age range 18-69 years, 5 atopic, 7 men) applied randomly in turn TS and RS for 5 days in a double-blind crossover clinical trial. Nasal airflow resistance (NAR), nasal symptoms (6 grade scoring), frequency of application (times/day), and side-effects were recorded.
RESULTS
Mean ratio TS/RS of areas under the resistance/time curves for NAR +/- 90% CI: 3.56 +/- 0.92; mean TS-RS differences +/- 95% CI: for congestion: -1.12 +/- 0.59, for frequency of application: -1.10 +/- 0.20. Subjects experienced fewer side-effects with TS.
CONCLUSIONS
A mucoadhesive solution with a decongestant had a greater and longer lasting effect on nasal congestion in subjects with perennial allergic rhinitis than the commercially available decongestant solution. It also caused fewer side effects.
