| Popis: | The present study aimed to enhance the transdermal delivery of lacidipine by niosomal vesicles. Lacidipine niosomes were generated using the ultrasonic method, and Span 60 was used as a nonionic surfactant. Formulations were prepared containing Span 60 and cholesterol in 1:1 and 2:1 ratios, respectively, with essential oils added at increasing concentrations. The formulated niosomes had nano-vesicles with entrapment efficiency ranging from 75.81% to 91.25% and in-vitro drug release ranging from 80.61% to 89.81%. The optimal formulation was selected based on particle size, entrapment efficiency and in-vitro drug release. Optical microscopy and high-resolution transmission electron microscopy studies revealed a spherical shape of the niosomal vesicles. Fourier transform infrared spectroscopy, differential scanning calorimetry and X-ray diffraction studies confirmed complete encapsulation of the drug in the niosomal vesicles. The optimized formulation was also incorporated into a gel base, which was then evaluated for appearance, pH, viscosity, spreadability, in vitro drug release and stability. Overall, the results indicated that the developed niosomal lacidipine vesicles may provide an alternative to existing delivery systems for this drug. |
