Abstract
Aims: The aims of this research were to develop and characterize liquid and solid micro emulsifying drug delivery system (L-SMEDDS and S-SMEDDS) containing black seed oil.
Study Design: Experimental Research Design (laboratory).
Place and Duration of Study: The study was conducted at research laboratory of pharmacy department UNISBA, between August 2018- August 2019.
Methodology: The optimization of L-SMEDDS was carried out using various comparison of oil, surfactant, and cosurfactant. All formulations were evaluated for percent transmittance, emulsification time, dispersibility, robustness, and thermodynamic stability. The best formula of L-SMEDSS was evaluated for globule size distribution and converted to S-SMEDDS by spray drying method using aerosil 200 as adsorbent. S-SMEDDS were evaluated for organoleptic, flowability, compressibility, emulsification time, dispersibility, robustness and surface morphology.
Results: The best formula of L-SMEDDS contains tween 80 as a surfactant and PEG 400 as cosurfactant (2:1) with a ratio of oil and Smix (2:8). The L-SMEDDS preparation meets the requirement of percent transmittance (95.77%), emulsification time (37.67 seconds), grade A of dispersibility, stable of robustness and thermodynamics study with the average of globule size was 231 nm. S-SMEDDS preparation meets the requirement of the moisture content, flowability, emulsification time, and stable on robustness testing with a spherical shape.
Conclusion: L-SMEDDS and S-SMEDDS of black seed oil have been developed and have good physical characteristics and stability.
