Mefenamic acid as pain relief drug belongs to the biopharmaceutics classification system (BCS) class II which is practically insoluble in water causing extremely low dissolution in gastrointestinal tract. The self nanoemulsifying drug delivery system (SNEDDS) is a new innovation pharmaceutical dosage form that has effectively known to increase solubilization of hydrophobic drug in polar solvent. In this study the capryol-90 was selected as oil phase in SNEDDS as it showed maximal solubility of mefenamic acid (20 mg/mL). Combination of polysorbate-80 and PEG-400 as a generally regarded as safe (GRAS) excipient were used as surfactant and co-surfactant in SNEDDS due to its high HLB property that can increase mefenamic acid solubility in water. The ternary phase diagram of capryol-90, polysorbate-80, and PEG-400 was constructed in advance to obtain the component concentration of spontaneous nanoemulsion region. Model simplex-lattice-design cooperated in Design-Expert®10 was used to define SNEDDS mefenamic acid formula. Optimized mefenamic acid SNEDDS formula consisted of 20% capryol-90, 31.62% polysorbate-80, and 48.38% PEG-400. Characterization study of Optimized mefenamic acid SNEDDS formula showed improvement of drug content (102.820 ± 4.950)%, emulsification time (421.015 ± 1.290) second, and viscosity (0.927 ± 0.017) mm2/s 30oC. One way ANOVA statistical analysis result of optimal formula SNEDDS (105.210 ± 4.425)% of drug content, commercial generic caplet (0.917 ± 0.094)%, and mefenamic acid powder capsule (10.446 ± 0,333)% gave significant value (sig*) below than 0.05. Optimal formula proved that SNEDDS can significantly increase mefenamic acid dissolution of pH 7.4 (ileum fluid). The optimal formula of mefenamic acid SNEDDS successfully formed an uniformity droplet size (PDI 0.18) with mean size 241.9 nm and  the surface charge has a value of -16.5 mV respectively.

Objective: The aim of the present work was to enhance the solubility of rosuvastatin calcium by self-nano emulsifying drug delivery system (SNEDDS) using mixtures of oil, cosolvent, surfactant and cosurfactant. Methods: Based on solubility study and emulsification efficiency, Preliminary investigations of various oils, surfactants and cosurfactants were carried out for the selection of the proper SNEDDS ingredients. Pseudo-ternary phase diagrams were constructed to identify the efficient self-emulsification region. A series of SNEDDS formulations were prepared using labrasol: cremophor EL with a combination of peceol: ethyl oleate by using the simplex lattice design. Prepared formulation evaluated for refractive index, turbidimetric, droplet size, zeta potential and polydispersity index, self-emulsification, stability tests, viscosity and in vitro diffusion studies. Results: The best formula for SNEDDS in the current study were:  15% oil (peceol: ethyloleatein 1:1 ratio), 50% Labrasol and 35% Cremophor EL. All the SNEDDS batches globule size was found to be varied from 22.90±1.50 nm to 43.90±1.40 nm. and no significant variations in globule size were observed after 3 mo stability studies. All the batches % transparency was found to be varied from 95.40±1.40% to 99.50±1.10% and drug diffused in 10 min varied from 63.65±1.51% to 93.72±1.46 %. Conclusion: The data suggest the use of rosuvastatin calcium SNEDDS to offer the potential for delivery and it increases the aqueous solubility and bioavailability of the drug.

The aim of the present study is to develop and optimize self-nanoemulsifying drug delivery systems (SNEDDS) to improve the topical bioavailability of poorly soluble ethanol extract of mangosteen peels and to get optimum method of SNEDDS by simplex lattice design, using Design Expert software ®version 7. Solubility of ethanol extract of the mangosteen peels was estimated in various compositions to select proper components combinations. Virgin coconut oil/ VCO (oil), Tween® 80 (surfactants) as well as polietilenglikol 400 (PEG 400) (co-surfactants) were employed to construct pseudo-ternary phase diagrams. Transmittance and pH, droplet size, zeta potential, and thermodynamic stability were performed to optimize formulations from phase diagram. Fourteen formulations composed of VCO, Tween 80 and PEG 400 at simplex lattice design ratios were selected. The results showed that the ethanol extract of the mangosteen peels SNEDDS optimum consisting of Cremophor EL as the surfactant, PEG 400 as the co-surfactant, and VCO as the oil phase with a ratio of 5.27: 1: 1.72. Evaluation of SNEDDS with an optimum formulation with drug loading value of 125 mg/5 mL, emulsification time of 5,2 seconds, transmittance value of 74,6552 %, pH value 5,85 and has a particle size of 18,9 nm. Ethanol extract of the mangosteen peels loaded SNEDDS, with enhanced solubilization and nanosizing, and has potential to improve the absorption of drug and increase its topical antimicrobial activity against Staphylococcus aureus.

Anti Hiv

Kurkumin terbukti memiliki aktivitas sebagai anti-tumor, anti-inflamasi, anti-virus, anti-oksidasi dan anti HIV. Penggunaan kurkumin dalam proses pengobatan jangka panjang memberikan toksisitas yang rendah sehingga secara klinis akan sangat menguntungkan untuk dikembangkan. Kandungan aktif kurkumin yang berasal dari ekstrak tanaman curcuma longa ini mempunyai bioavaiblitas yang sangat rendah. Hal ini berkaitan karena kelarutan kurkumin yang jelek dalam air (11 ng/ml, pH 5,0) sehingga sedikit diserap di saluran pencernaan. Permasalahan ini dapat diatasi dengan membuat sediaan kurkumin dalam bentuk Self Mikroemulsi Drug Delivery System (SMEDDS) Penelitian awal dilakukan skrining terhadap kelarutan kurkumin dengan pembawa berbagai jenis minyak, surfaktan dan kosurfaktan. Hasil skrining dilanjutkan dengan pemilihan formula optimum SMEDDS kurkumin dengan menggunakan metode Simpelx Lattice Design (SLD). Tiga variabel akan memberikan 14 formula SMEDDS kurkumin yang masing-masing formula dilakukan pengujian terhadap karakteristiknya sebagai titik kritis meliputi : % transmitan, waktu emulsifikasi dan drug loading. Hasil masing-masing pengujian dianalisis datanya dengan Design Exspert versi 7 dan dilanjutnya validasi formula optimum dengan uji T dengan taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa skrining awal terhadap kurkumin didapatkan kelarutan yang terbesar pada jenis minyak zaitun, surfaktan Tween 80 dan kosurfaktan PEG 400. Ketiga jenis bahan ini dilakukan optimasi dengan SLD memberikan formula optimum komposisi SMEDDS kurkumin dengan komposisi 0,026 minyak zaitun ; 0,0913 Tween 80 dan 0,061 PEG 400.
