The nasal mucociliary clearance is an important defense mechanism of the upper respiratory tract. It is known to be influenced by many pharmacologic substances. We investigated the effects of three topical intranasal antiallergic formulations containing disodium cromoglycate (DNCG), dimethindene maleate (DMM), and azelastine‐HCL (AZL) on nasal ciliary beat frequency (CBF) in vitro. Nasal ciliated cells were harvested from 16 healthy volunteers. Cells were diluted 1:10 in culture medium and incubated with a placebo formulation (PLAC), containing 0,022% benzalkonium chloride, which was part of all formulations, a registered 2% formulation of DNCG, a 0.1% formulation of DMM, and a registered 0.1% formulation of AZL. After an incubation period of 20 min, CBF was registered by a photoelectric measurement device. Under control conditions (CONTROL), CBF was 11 4±1 3 Hz. PLAC reduced CBF to 9.7±2.3 Hz (NS). DNCG reduced CBF t o 9.7±2 Hz (NS). DMM reduced CBF to 7.2+1.7 Hz F<0.O5 vs CONTROL, NS vs PLAC), and AZL reduced CBF to 0.9+1.8 Hz P ≤ 0.05 vs CONTROL, P ≤ O.001 vs DNCG, P < 0.001 vs PLAC). In conclusion, a possible influence of antiallergic intranasal formulations on nasal ciliary function has to be considered in clinical application.
