Design and optimization of self-nanoemulsifying formulations for lipophilic drugs

Nanotechnology, 2015

The aim of this work was to improve the in vitro dissolution of simvastatin through development of selfnanoemulsifying tablets. Various modified oils, surfactant and co-surfactant mixtures were used to prepare different self-nanoemulsifying drug delivery systems (SNEDDS) whose composition was optimized using drug-solubility, ternary phase diagram, system stability and droplet size distribution studies. Optimized SNEDDSs, with acceptable surfactant ratio, stability and particle size (nano-range) upon dilution with simulated gastric fluid (SGF, pH 1.2) under gentle agitation conditions, were loaded onto microcrystalline cellulose and nano-size colloidal silicon dioxide powders using loading factor (L f) = 0.2 and excipient ratio (R) = 20. Prepared powders were compressed into tablets and the in vitro performance of the prepared self-nanoemulsifying tablets was investigated. Results revealed that systems with 10% relatively polar oils (C 8), 60% Cremophore ® RH 40 (surfactant), and 30% Transcutol ® HP (co-surfactant), acquired good self-nanoemulsification properties either in liquid or tableted forms. Prepared self-nanoemulsifying tablets demonstrated significantly higher dissolution rates, compared to direct compression tablets (DCT) and marketed tablet (Zocor ®). In conclusion, self-nanoemulsifying tablets were able to introduce simvastatin successfully in a unique immediate-release solid dosage form.

A Scientific Review on Nanoemulsion for Targeting Drug Delivery System

2019

Nanoemulsions have attracted great attention in research, dosage form design, and pharmacotherapy. This is as a result of some attributes peculiar to nanoemulsions such as optical clarity, ease of preparation, thermodynamic stability and increased surface area. Poor water solubility remains the main culprit for the formulation scientist which can be overcome by canonization. Nanoemulsion is a kinetically stable and isotropic system of two immiscible liquids in the submicron size range. Nanoemulsions are composed of oil droplets dispersed in an aqueous medium and stabilized by surfactant molecules. Many parenteral nutrition and drug emulsions on the market confirm the safe use of NE over the years. Parenteral emulsions loaded with APIs (active pharmaceutical ingredients) are considered as drug delivery systems (DDS). DDS focuses on the regulation of the in-vivo dynamics, such as absorption, distribution, metabolism, and extended bioavailability, thereby improving the effectiveness an...

A review article: Drug delivery systems, preparation techniques, and biological applications using nanoemulsion as a novel platform

Journal of University of Anbar for Pure Science

Nanotechnology, particularly nanoemulsions (NEs), is an essential topic that has piqued the interest of researchers over the years. These significant molecules feature a spherical solid structure, a lipophilic amorphous negative charge surface, with small droplet size, and a large surface area, all of which contribute to the promising future of nanomedicine and the importance of NEs in a variety of sectors. The advantages and disadvantages of the components, preparation, characterization, assessment, and applications as a delivery medication system are summarized in this review paper. There are two different methods for NEs preparation: the high and low energy methods. In high energy methods, high-pressure homogenization, ultrasonication micro fluidization, and Spontaneous emulsification are described thoroughly. Low energy approaches emphasize phase inversion temperature, solvent evaporation technology, and hydrogel technologies. Low-energy procedures should be preferred over high-energy methods since they utilize less energy and do not necessitate the use of specific instruments. The transdermal application, aerosolized, ingestible NEs, and parenteral techniques are the four primary lines of biomedical uses of NEs as a delivery strategy. To summarize, these novel strategies are very promising, but additional research is needed to fully understand the relationship between NE formulation and physiological and pathological problems associated with diverse preparation, characterization, and administration routes. .

Design development and evaluation of self nanoemulsifying drug delivery system of simvastatin

2018

The aim of this work was to improve the invitro dissolution of Simvastatin through development of self nanoemulsifying capsules. Simvastatin is a poorly-water soluble drug and cholesterol lowering agent. It has poor oral bioavailability (5%) due to its low solubility. So self nanoemulsifying drug delivery of Simvastatin increases its solubility and enhance its bioavailability. Nanoemulsions of ternary phase diagrams constructed usingvarious modified oils, Smix (mixture of surfactant and co-surfactant) were used to prepare different selfnanoemulsifying drug delivery systems (SNEDDS). Whose composition was optimized using drug-solubility, system stability and droplet size distribution studies. Optimized SNEDDS were subjected to Characterization studies. Results revealed that systems with 10% relatively polar oils, Smix (5: 1) that means 60% Cremophore® RH 40 (surfactant), and 30% Ethanol(co-surfactant), acquired good self-nanoemulsification properties. The optimized SNEDDS Characteriz...

Current State of Nanoemulsions in Drug Delivery

Journal of Biomaterials and Nanobiotechnology, 2011

Nanoemulsions have attracted great attention in research, dosage form design and pharmacotherapy. This is as a result of a number of attributes peculiar to nanoemulsions such as optical clarity, ease of preparation, thermodynamic stability and increased surface area. Nanoemulsions also known as submicron emulsions serve as vehicles for the delivery of active pharmaceutical ingredients as well as other bioactives. They are designed to address some of the problems associated with conventional drug delivery systems such as low bioavailability and noncompliance. The importance of design and development of emulsion nanocarrier systems aimed at controlling and/or improving required bioavailability levels of therapeutic agents cannot be overemphasized. Reducing droplet sizes to the nanoscale leads to some very interesting physical properties, such as optical transparency and unusual elastic behaviour. This review sheds light on the current state of nanoemulsions in the delivery of drugs and other bioactives. The morphology, formulation, characteristics and characterization of nanoemulsions were also addressed.

Nanoemulsion as Novel Drug Delivery System: Development, Characterization and Application

Asian Journal of Pharmaceutical Research and Development

A dispersed nano-system with droplet sizes as small as submicrons is called a nanoemulsion. Nanoemulsions are thermodynamically stable, transparent, isotropic liquid mixtures of oil, water, surfactant, and co-surfactant. Nanoemulsion typically has droplet sizes between 20 and 200 nanometer. The size and composition of the scattered particles in a continuous phase are the primary distinctions between an emulsion and a nanoemulsion. This approach is intended to alleviate some of the issues that low bioavailability and noncompliance, two issues with traditional drug delivery systems, bring up.Today, nano emulsion can be created for a number of administration routes. A nano emulsion formulation can be considered an effective, secure, and patient-compliant pharmaceutical delivery method. Nowadays, nano emulsions have attracted a lot of interest in pharmacotherapy, dosage form design, and research. A surfactant and a cosurfactant can preserves the stability components of nanoemulsion.

Facile methodology of nanoemulsion preparation using oily polymer for the delivery of poorly soluble drugs

Drug Delivery and Translational Research

Aqueous solubility of an active pharmaceutical ingredient (API) is a determining factor that has a direct impact on formulation strategies and overall bioavailability. Fabrication of nanoemulsions of poorly soluble drugs is one of the widely utilized approaches to overcome this problem. However, thermodynamic instability and tedious manufacturing processes of nanoemulsions limit their clinical translation. Therefore, this study was focused on circumventing the abovementioned hurdles by utilizing the polymer as an oil phase, instead of conventional oils. The nanoemulsion was prepared via a facile low-energy nanoprecipitation method using renewable poly(δ-decalactone) (PDL), as an oil phase and Pluronic F-68 as surfactant. The prepared nanoemulsions were characterized in terms of size, drug encapsulation efficiency, stability, and toxicity. Five different hydrophobic drugs were utilized to evaluate the drug delivery capability of the PDL nanoemulsion. The prepared nanoemulsions with s...
