Abstract
Background and Objective:
Applying Ethosomal Gels (EGs) in transdermal drug delivery systems has evoked considerable interest because of their good water-solubility and biocompatibility. The aim of present study was to prepare and characterize ethosomes of antileprotic drug Dapsone (DAP) together with an antibiotic Cloxacillin Sodium (CLXS) which may deliver these drugs to targeted site more efficiently than marketed gel preparation of DAP and also overcome the problems related with oral administration of CLXS.
Methodology:
Ethosomes were prepared by cold method then characterized for particle size, Entrapment Efficiency (EE), zeta potential and permeation studies. Vesicular size was determined by Scanning Electron Microscopy (SEM) and found to be varied from 127±9.01 to 215±7.23 nm depending on the concentrations of soya lecithin and ethanol.
Results:
The average percent drug entrapment efficiency of formulations ranged between 52.31% to 73.51% and 49.07% to 71.91% for DAP and CLXS respectively. The high ethanol concentration in ethosomes has shifted the vesicular charge from positive to negative. It was observed that F1 and F2 formulations were having zeta potential of -25.08±1.03 mV and -50.11±1.97 mV respectively and do not aggregate rapidly. The drug release of ethosomes ranged from 84.68% to 96.58% and 64.89% to 84.21% for DAP and CLXS respectively. Ethosomal gel was prepared with optimized ethosome and studied for its release and physicochemical characteristics.
Conclusion:
Finally, G5 demonstrated better (p < 0.05) antileprotic effect to improve effectiveness, stability and to reduce side effects and toxicity associated with the chosen drugs in order to treat Leprosy.
