نانوايثوزومال جل حديث من الليركانيدبين هيدروكلوريدالمستخدم لعلاج ارتفاع ضغط الدم : تحسين باستخدام تصميم Box-Benkhen في المختبر وفي الجسم الحي
ملخص البحث
Poor bioavailability of drugs via oral route is the greatest challenge facing drug formulation. To overcome this obstacle,
transdermal route was commonly used as an alternative route to improve bioavailability. Lercanidipine HCl (LER) is a
vasoselective calcium-channel blocker that has a poor oral bioavailability of 10% due to its hepatic metabolism and low
solubility. The main objective of this study was to develop nanoethosomal LER gel for transdermal delivery to increase its skin
permeation and promote bioavailability. Nanoethosomes were prepared and optimized using a Box-Behnken design employing
ethanol injection method. The design studied the influence of Phospholipon 90G (PL90G), LER, and ethanol concentrations on
entrapment efficiency (EE%); vesicle size; % cumulative LER release (CLERR); and cumulative LER permeated per unit area at
24 h Q24(μg/cm
2
). The pharmacokinetic parameters of the optimized formulation were determined in rats. Nanoethosomes
showed a mean vesicle size between 210.87 and 400.57 nm and EE% ranging from 49.26 to 97.22%. The developed
nanoethosomes enhanced % CLERR and Q24values compared to drug suspension. The experimental parameters of optimized
formulation were very close to those calculated by software. The pharmacokinetics study showed three times statistically
significant (p< 0.05) enhancement in LER bioavailability following nanoethosomal LER gel transdermal application compared
to that of oral LER suspension. Nanoethosomes can be considered as a promising carrier for LER transdermal delivery, thus will
be fruitful therapy in hypertension management
