  • Objective To study the preparation process of bromhexine hydrochloride nasal drop,develop the assay method for the main component in the drop and evaluate its transdermal penetration in vitro. Methods The bromhexine hydrochloride was prepared with dispersion method. HPLC was used for the assay. The flow phase is methanol-acetic acid solution (55∶45). The flow rate was 1.0 ml/min. The detection wavelength was 247 nm. The column temperature was 30 ℃. The in vitro transdermal test was carried out on KM mice. Results Bromhexine hydrochloride nasal drop was a suspension preparation. Bromhexine hydrochloride presented good linearity in the range of 37.44-187.2 μg/ml with the regression equation Y=11.996X+124.6 (r=0.9999). The average recoveries of low,medium and high concentrations were 104.00%,101.59%,98.51% respectively with RSD of 0.89%,1.35%,0.35%(n=9). The cumulative penetration rate of bromhexine hydrochloride in 24 h was 60.29%. Conclusion This nasal drop formulation was acceptable. The preparation process was feasible and assay method was accurate and reliable.
