Dissolution Determination of Ambroxol Hydrochloride Orally Disinegreting Tablets / 医药导报

Objective To establish a method for the dissolution determination of ambroxol hydrochloride orally disinegreting tablets. Methods The UV spectrophotometry was used. The detecting wavelength was at 244 nm. The liquid of dissolution was hydrochloride(0.1 mol·L -1). Rotational speed was 50 r·min-1. Results The linearity range was 3.16-28.44 μg·mL-1.The regression equation was Y＝0.024 2X+0.018 3(r＝0.999 3).The RSD of repeatable test was 0.28%.The average recovery of methodology was 100.4% and RSD was 0.77%. Conclusion The method is simple and reliable, and can be used for the dissolution determination of ambroxol hydrochloride orally disinegreting tablets.
