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.

Mefenamic acid is a non-steroidal anti-inflammatory drug (NSAID) which has analgesic, anti-inflammatory and antipyretic effects. Mefenamic acid works by inhibiting prostaglandin synthesis as an inflammatory mediator. Mefenamic acid has low drug solubility and a long process of dissolution in the body which greatly affects the speed of absorption and bioavailability of the drug. In this study, mefenamic acid nanoemulsion formulation was carried out through a Self-Nanoemulsifying Drug Delivery System (SNEDDS) delivery system. SNEDDS is a drug delivery method through isotropic oil extraction, surfactants, cosurfactans and drug that form oil in water (m/a) emulsions which when in contact with the water phase in the digestive tract wiil from a nanoemulsion that occurs spontaneously so that the drug dissolves with a particle size small so as to increase the effective surface area for absorption. The purpose of the study was to determine the ratio of surfactant and cosurfactant composition to the optimum formula of SNEDDS of mefenamic acid with VCO as an oil phase. The SNEDDS formula was obtained by mixing the surfactants tween 80 and span 80, cosurfactant PEG 400 and VCO as the oil phase using the characterization of determining the optimum formula, namely emulsion formation, transmittance and emulsification time. The composition of the optimum formula of SNEDDS of mefenamic acid is 1 mL VCO; 1 mL PEG 400; 6 mL tween 80; 1 mL span 80. Optimum formula showed clear emulsion results, with transmittance values of 89,04% and emulsification time under 1 minute. In this study produced the optimum formula SNEDDS the met the criteria based on droplet size parameters of 153,5 nm, potential zeta value of 8,2 mV and showed good stability.

Lipids are used as vehicles for the preparation of various formulations prescribed for administrations, including emulsions, ointments, suspension, tablets, and suppositories. The first parental nano-emulsion was discovered from the 1950s when it was added to the intravenous administration of lipid and lipid-soluble substances. Lipid-based drug delivery systems are important nowadays. Solid nanoparticles (SLN) and Nanostructured lipid carriers (NLC) are very proficient due to the ease of production process, scale-up capability, bio-compatibility, the biodegradability of formulation components and other specific features of the proposed route. The administration or nature of the materials must be loaded into these delivery systems. The main objectives of this review are to discuss an overview of second-generation nanoparticles, their limitations, structures, and route of administration, with emphasis on the effectiveness of such formulations. NLC is the second generation of lipid nanoparticles having a structure like nanoemulsion. The first generation of nanoparticles was SLN. The difference between both of them is at its core. Both of them are a colloidal carrier in submicron size in the range of 40-1000 nm. NLC is the most promising novel drug delivery system over the SLN due to solving the problem of drug loading and drug crystallinity. Solid and liquid lipids combination in NLC formation, improve its quality as compare to SLN. NLC has three types of structures: random, amorphous, and multiple. The random structure containing solid-liquid lipids and consisting crystal and the liquid lipid irregular in shape; thereby enhance the ability of the lipid layer to pass through the membrane. The second is the amorphous structure. It is less crystalline in nature and can prevent the leakage of the loaded drug. The third type is multiple structures, which have higher liquid lipid concentrations than other types. The excipients used to form the NLC are bio-compatible, biodegradable and non-irritating, most of which can be detected using GRAS. NLC is a promising delivery system to deliver the drug through pulmonary, ocular, CNS, and oral route of administration. Various methods of preparation and composition of NLC influence its stability Parameters. In recent years at the educational level, the potential of NLC as a delivery mechanism targeting various organs has been investigated in detail.

A key challenge for nanoparticles-based drug delivery system is to achieve manageable drug release in tumour cell. In this study, a versatile system combining photothermal therapy and controllable drug release for tumour cells using temperature-sensitive block copolymer coupled Au NRs@SiO2 is reported. While the Au NRs serve as hyperthermal agent and the mesoporous silica was used to improve the drug loading and decrease biotoxicity. The block copolymer acted as “gatekeeper” to regulate the release of model drug (Doxorubicin hydrochloride, DOX). Through in vivo and in vitro experiments, we achieved the truly controllable drug release and photothermal therapy with the collaborative effect of the three constituents of the nanocomposites. The reported nanocomposites pave the way to high-performance controllable drug release and photothermal therapy system.
