Abstract：
:Sodium taurodihydrofusidate (STDHF) is one of the most promising absorption enhancers for nasal delivery of peptide drugs. Drugs and additives in nasal formulations should not interfere with the self-cleaning capacity of the nose by the ciliary epithelium. Measured in vitro on human adenoid tissue with a photoelectric method, STDHF was found to induce ciliostasis at concentrations of 0.3% (w/v) and higher. STDHF (0.3%) is less ciliostatic than laureth-9 (0.3%) or deoxycholate (0.3%). Glyco- and taurocholate (0.3%) show only very mild effects on nasal ciliary movement. Human insulin (1%) has no ciliostatic potency in vitro, whereas a combination of human insulin (1%) and STDHF (1%) is ciliostatic but not as potent as STDHF (1%) alone.
