Abstract

Context: Assessment of nisoldipine (NSP) skin flux using validated high-performance liquid chromatographic (HPLC) method. Aim: A validated HPLC method was developed for estimation of NSP in skin permeated samples from matrix type transdermal films. Materials and Methods: Chromatographic separation was done using Phenomenex Luna C18 column (150 mm × 4.6 mm i.d. 5 μm) employing acetonitrile:water:methanol (40:35:25 v/v) as the mobile phase. Settings and Design: The calibration solutions were prepared in the linearity range of 0.250-50 μg/mL. The flow rate was maintained at 0.8 mL/min at 25°C. 10 μL samples were injected and were monitored using photodiode array detector at a wavelength of 275 nm. Results: The limit of detection and limit of quantification for NSP were recorded as 0.125 μg/mL and 0.150 μg/mL, respectively. The correlation coefficient (r2) values for intraday and interday were >0.998 and % relative standard deviation values were <10%. Conclusions: The method was validated as per International Conference on Harmonization guidelines, found to be simple, sensitive, cost effective and was successfully used for ex vivo skin permeation studies of NSP from matrix type transdermal films.
