Furosemide is a potent diuretic drug that has low bioavailability. Furosemide can be formulated into nanoemulsion preparations using the SNEDDS method to increase its bioavailability as SNEDDS can form stable nanoemulsions with droplet sizes 200 nm. This study aims to identify the optimum formula for variations in the concentration of surfactant Tween 80 and cosurfactant PEG 400 based on the characterization tests of emulsification time, percent transmittance, and drug loading. The independent variables used in this study were Tween 80 and PEG 400. Seven furosemide SNEDDS formulas from the Simplex Lattice Design (SLD) method were tested for characterization in the form of emulsification time, percent transmittance, and drug loading. The characterization results were optimized using Simplex Lattice Design. The optimum formula was re-characterized, including emulsification time, percent transmittance, drug loading, particle size, zeta potential, and in vitro dissolution. The results were then compared with theoretical values and analyzed using the One-Sample T-test method. Optimization results showed Tween of 61.4922% and PEG 400 of 18.5078% with the characterization of emulsification time 15.25 seconds, percentage transmittance 94.20%, drug loading 50 100.2 ppm, particle size 12.18 nm. Furthermore, the zeta potential was -17.6 mV, and the in vitro dissolution rate reached 106.71% within 15 minutes.

The objective of this study was to develop a pharmaceutical O/W emulsion containing plant-derived polyphenol extracts and evaluate its stability and antioxidant activity. O/W emulsions were prepared using ionic surfactant polysorbate 80 (Tween 80®). The odorwas adjusted with few drops of blue sea fragrance. DPPH (1,1-diphenyl-2-picrylhydrazyl) assay was used to evaluate the antioxidant activity of the plant extracts alone and emulsions containing these extracts. Physical stability was assessed by submitting the emulsions to storage at 8 ºC, 25 ºC, 40 ºC and 40 ºC + 70% RH (relative humidity) for two months. Various physical characteristics of emulsions monitored, include color, creaming, liquefaction, centrifugation and pH. Brookfield rotational rheometer was used to determined viscosities and rheological behavior of emulsions. Different types of emulsion were determined microscopically, while pH values of emulsions were measured by a pH meter. Electrical conductivity data confirmed that the outer phase was water. Samples presented an acceptable pH value for an external topical use. Shear thinning behaviour was observed for all emulsions. The polyphenol-rich-plant-derived extracts alone and the extract containing emulsions showed good antioxidant activities. This research confirmed that the method used was suitable for preparing emulsions with Hippophae rhamnoids and Cassia fistula extracts, suggesting that those emulsions are suitable for topical use.
