AAPS PharmSciTech 2021; 22:256. [PMID: 34676456 DOI: 10.1208/s12249-021-02109-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Accepted: 08/02/2021] [Indexed: 11/30/2022] Open
Abstract
The authors attempted to fabricate a novel lipid-based formulation of a lipophilic drug, nisoldipine (NISO). As NISO belongs to BCS class 2 drug, it suffers from low bioavailability (5%). Hence, the research was intended to ameliorate oral bioavailability of NISO via intestinal lymphatic transport. The NISO loaded self microemulsifying drug delivery system (SMEDDS) (NISO SMEDDS) was prepared using Peceol, Cremophor EL, and Transcutol HP. The Cremophor EL and Transcutol HP at 1:1 ratio showed maximum microemulsifying area, and average globule size was 16.78 ± 0.97 nm with PDI 0.121 ± 0.024. Cellular uptake studies (confocal microscopy and flow cytometry) using Caco-2 cells depicted higher fluorescence with coumarin-6 loaded SMEDDS as that of coumarin-6 solution which indicated deeper penetration. Mean fluorescence intensity (MFI) of coumarin-6 loaded SMEDDS was significantly improved (9.92-fold) in contrast to coumarin-6 solution. The NISO SMEDDS showed enhanced permeability (5.02 times) across Caco-2 cells compared to NISO suspension. The bioavailability improvement with NISO SMEEDS was 2.14 times relative to suspension, and lymphatic uptake was involved in oral absorption of NISO SMEDDS.

Abstract
Self-emulsifying drug delivery system (SEDDS) is a kind of solid or liquid formulation composed of drugs, oil, surfactant and cosurfactant. It could form a fine emulsion (micro/nano) in the gastrointestinal tract after oral administration. Later on, the formed emulsion is absorbed through the lymphatic pathway. The oral bioavailability of drugs in SEDDS would be improved for bypassing the first-pass effect of the liver. Therefore, SEDDS has become a vital strategy to increase the oral bioavailability of poor watersoluble drugs. In addition, there is no aqueous phase in SEDDS, thus SEDDS is a homogeneous system, consequently being suitable for large-scale production and more stable than conventional emulsion. However, the role of formulation aspects in the biological property of SEDDS is not fully clear. In order to prepare the satisfying SEDDS to improve oral drug bioavailability, we need to fully understand the various factors that affect the in vivo behavior of SEDDS. In this review, we would explore the role of ingredient (drugs, oils, surfactant and cosurfactant) of SEDDS in increasing oral drug bioavailability. We would also discuss the effect of physicochemical property (particle size and zeta potential) of SEDDS on the oral drug bioavailability enhancement. This review would provide an approach to develop a rational SEDDS to improving oral drug bioavailability. Lay Summary: Self-emulsifying drug-delivery system (SEDDS) has been proven to be promising in ameliorating the oral bioavailability of poor water-soluble drugs. This review highlighted the influence of excipients and physicochemical property of SEDDS on the formation of emulsion and the oral absorption of drugs in the body.

Abstract
Magnolol, known to have extensive biological activities, is the major bioactive ingredient isolated from the root and stem bark of Magnolia officinalis. However, the clinical application of magnolol is limited by poor aqueous solubility and absorption. The aim of this study is to develop novel mixed micelles and nanosuspensions composed of two biocompatible copolymers, Soluplus® and Poloxamer 188, and to improve the solubility and oral bioavailability of magnolol. The magnolol-loaded mixed micelles (MMs) and magnolol nanosuspensions (MNs) were prepared to use film hydration and antisolvent methods, respectively. The optimal MMs and MNs formulations were prepared to use magnolol, Soluplus®, and Poloxamer 188 in ratios of 1:12:5 and 2:1:1, respectively. The average particle size of MMs was 111.8 ± 14.6, and MNs was 78.53 ± 5.4 nm. The entrapment and drug loading efficiency for MMs were 89.58 ± 2.54% and 5.46 ± 0.65%, correspondingly. The drug loading efficiency of MNs was 42.50 ± 1.57%. In the in vitro release study, MMs showed a slow drug release while that of MNs was fast. The results of the Caco-2 transcellular transport study indicated that both MMs and MNs increased the permeation of magnolol. MMs and MNs markedly promoted gastrointestinal drug absorption by 2.85 and 2.27-fold, respectively, as shown in the pharmacokinetics study. These results indicated that both MMs and MNs formulations prepared with Soluplus® and Poloxamer 188 are promising drug delivery systems for improving the oral absorption of insoluble drugs in the gastrointestinal tract.

Abstract
Cancer is the disease of this era. Its therapy is moving through ups and downs not only due to poor effectiveness of many treating drugs, but also due to the serious side effects always evolving. In an attempt to overcome this problem, many systems, including lipid-based carriers, have been exploited for their oral delivery. Throughout this study, the meta-analysis tool was used to combine data from different studies and extract evidences that lipid-based carriers enhance the oral bioavailability. Consequently, increasing the efficiency and the reduction in side effects of drugs would follow. Accordingly, the usual parameter to indicate the bioavailability; the area under effect curve (AUC) was used where the lipid carriers have proven their superiority over conventional formulations. Interestingly, by comparing microemulsion/self-microemulsifying system (SMEDDS) versus liposomes/pro-liposomes as subgroups of the meta-analysis study, insignificant differences were recorded between them.

Abstract
Purpose: Insulin resistance is a characteristic of non-insulin-dependent diabetes mellitus associated with obesity and caused by the failure of pancreatic beta cells to secrete sufficient amount of insulin. Andrographolide (AND) improves beta-cell reconstruction and inhibits fat-cell formation. This research aimed to improve the delivery of water-insoluble AND in self-nanoemulsifying (ASNE) formulation, tested in streptozotocin (STZ)-induced diabetic rats and 3T3-L1 preadipocyte cells. Methods: A conventional formulation of AND in suspension was used as a control. The experimental rats were orally administered with self-nanoemulsifying (SNE) and suspension of AND for 8 days. Measurements were performed to evaluate blood glucose levels in preprandial and postprandial conditions. Immunohistochemistry was used to assess the process of islet beta cell reconstruction. In vitro study was performed using cell viability and adipocyte differentiation assay to determine the delivery of AND in the formulation. Results: ASNE lowered blood glucose levels (day 4) faster than AND suspension (day 6). The histological testing showed that ASNE could regenerate pancreatic beta cells. Therefore, ASNE ameliorated pancreatic beta cells. The in vitro evaluation indicated the inhibition of adipocyte differentiation by both AND and ASNE, which occurred in a time-dependent manner. ASNE formulation had better delivery than AND. Conclusion: ASNE could improve the antidiabetic activity by lowering blood glucose levels, enhancing pancreatic beta cells, and inhibiting lipid formation in adipocyte cells.

Abstract
Encapsulation in packaging of food ingredients is of great interest at micro and nano levels. It is a distinct process leading to the entrapping of one substance within another material. Lipid oriented encapsulation methods are currently considered as a superior choice for encapsulation of sensitive ingredients, focusing on foods and dietary supplements of hydrophobic and hydrophilic molecules along with bioactive compounds, food ingredients supplementary systems for therapeutic purpose. Liposome and nanoliposome techniques have been widely used in food industry in nutrient enrichment and supplements. It enhances the sensory attributes and shelf life of the food product and serves as an alternative to micro encapsulation. These lipid and water oriented systems have distinguished advantages and provide higher surface area in food processing, which increases product solubility, bioavailability and permits accurate targeting of the encapsulated material to a greater extent in food and nutraceutical production. This review article focuses on nanoliposome, its preparation techniques, advantages and application of nanoliposome in food and nutraceutical process.

Abstract
Phospholipids are amphiphilic lipids with versatile properties making them promising excipients for enabling formulations for oral drug delivery. Unfortunately, systematic studies on how phospholipid type and content affect oral absorption are rare. Often, only one phospholipid type is used for the formulation development and only one formulation, optimized according to in vitro parameters, is included in oral bioavailability studies. Using this approach, it is unclear if a certain in vitro parameter is predictive for the in vivo performance. In this study, a labor-saving in vitro permeation screening method was combined with a pharmacokinetic study in rats to for the first time systematically compare two types of phospholipid-based solid dispersions. The dispersions contained the drug celecoxib and monoacyl or diacyl phosphatidylcholine at different drug-to-phospholipid ratios. The in vitro screening revealed: 1) none of the formulations with high phospholipid content increased permeation, 2) phospholipid content was negatively correlated with permeation, and 3) mono and diacyl-phosphatidylcholine formulations performed equally. The pharmacokinetic study revealed: 1) At low phospholipid content absorption was enhanced, 2) phospholipid content was negatively correlated with absorption, and 3) monoacyl and diacyl phosphatidylcholine formulations performed equally. Apart from the reference (suspension), the in vitro permeation screening thus predicted the formulations in vivo performance.

Abstract
Simvastatin a cholesterol-lowering agent used to treat hypercholesterolemia, coronary heart disease, and dyslipidemia. However, simvastatin (SV) has shown low oral bioavailability in GIT. The main purpose of the work was to develop proliposomal formulations to increase the oral bioavailability of SV. Film deposition on the carrier method has been used to prepare the proliposomes. The proliposomes were assessed for morphology, particulate size, entrapment efficacy, drug-polymer compatibility, in vitro and in vivo studies. FTIR and DSC results revealed no drug-polymer interaction. SEM and XRD analysis conform; proliposomes are spherical, amorphous in nature, so that it enhances the solubility of SV between 15.01 ± 0.026 and 57.80 ± 0.015 μg/mL in pH 7.4 phosphate buffer. The optimised formulation (PL6) shows drug release up to 12 h (99.78 ± 0.067%). The pharmacokinetics of pure SV and SV proliposomes (SVP) in rats were Tmax 2 ± 0.5 and 4 ± 0.7 h, Cmax 10.4 ± 2.921 and 21.18 ± 12.321 μg/mL, AUC0-∞ 67.124 ± 0.23 and 179.75 ± 1.541 μg/mL h, respectively. Optimised SVP shows a significant improvement in the rate and absorption of SV. The optimised formulation showed enhanced oral bioavailability of SV in Albino Wister rats and offers a new technique to improve the poor water-soluble drug absorption in the gastrointestinal system.

Abstract
It has been known that a considerable number of drugs in clinical use or under development are water-insoluble drugs with poor bioavailability (BA). The liposomal delivery system has drawn attention as one of the noteworthy approaches to increase dissolution and subsequently absorption in the gastrointestinal (GI) tract because of its biocompatibility and ability to encapsulate hydrophobic molecules in the lipid domain. However, there have been several drawbacks, such as structural instability in the GI tract and poor permeability across intestinal epithelia because of its relatively large size. In addition, there have been no liposomal formulations approved for oral use to date, despite the success of parenteral liposomes. Nevertheless, liposomal oral delivery has resurged with the rapid increase of published studies in the last decade. However, it is discouraging that most of this research has been in vitro studies only and there have not been many water-insoluble drugs with in vivo data. The present review focused on the in vivo evidence for the improved BA of water-insoluble drugs using liposomes to resolve doubts raised concerning liposomal oral delivery and attempted to provide insight by highlighting the approaches used for in vivo achievements.

Abstract
The therapeutic efficacy of orally administered drugs is often restricted by their inherent limited oral bioavailability. Low water solubility, limited permeability through the intestinal barrier, instability in harsh environment of the gastrointestinal (GI) tract and being substrate of the efflux pumps and the cytochrome P450 (CYP) can impair oral drug bioavailability resulting in erratic and variable plasma drug profile. As more drugs with low membrane permeability are developed, new interest is growing to enhance their intestinal permeability and bioavailability. A wide variety of nanosystems have been developed to improve drug transport and absorption. Sufficient evidence exists to suggest that nanoparticles are able to increase the transepithelial transport of drug molecules. However, key questions remained unanswered. What types of nanoparticles are more efficient? What are preclinical (or clinical) achievements of each type of nanoformulation in terms of pharmacokinetic (PK) parameters? Addressing this issue in this paper, we have reviewed the current literature regarding permeability enhancement, permeability assessment methods and changes in PK parameters following administration of various nanoformulations. Although permeability enhancement by various nanoformulations holds great promise for oral drug delivery, many challenges still need to be addressed before development of more clinically successful nanoproducts.

Optimization was done employing 32 full factorial design. The developed formulation was assessed for in vitro,cell line, ex vivo and in vivo studies.Results: The experimental results indicated homogeneity of the nanoemulsion with globule size of 62.35 ± 2.55 nm and PDI value of 0.108 ± 0.01 with negative zeta potential (-26.2 ± 3.6 mV). Transmission electron microscopy showed spherical oil globules morphology. The in vitro diffusion study showed significant increase in drug release from NE formulations (98.51 ± 2.64%) as compared to plain drug dispersion (29.73 ± 2.15%) in 0.1 N HCl + 0.5% SLS medium. Moreover, higher quantitative and qualitative uptake of nanoemulsion via Caco-2 cells showed superior intestinal absorption and improved therapeutic activity of nisoldipine when compared to drug dispersion. Pharmacokinetic and pharmacodynamic study confirmed significantly (p ˂ 0.05) greater bioavailability and antihypertensive activity of nisoldipine nanoemulsion when compared to its dispersion. These results are visualized in abstract figure.Conclusion: Thus, prepared nanoemulsion showed potential as oral delivery system for nisoldipine with superior oral bioavailability and therapeutic efficacy over drug dispersion.

Abstract
Colon targeted drug delivery systems have gained a great deal of attention as potential carriers for the local treatment of colonic diseases with reduced systemic side effects and also for the enhanced oral delivery of various therapeutics vulnerable to acidic and enzymatic degradation in the upper gastrointestinal tract. In recent years, the global pharmaceutical market for biologics has grown, and increasing demand for a more patient-friendly drug administration system highlights the importance of colonic drug delivery as a noninvasive delivery approach for macromolecules. Colon-targeted drug delivery systems for macromolecules can provide therapeutic benefits including better patient compliance (because they are pain-free and can be self-administered) and lower costs. Therefore, to achieve more efficient colonic drug delivery for local or systemic drug effects, various strategies have been explored including pH-dependent systems, enzyme-triggered systems, receptor-mediated systems, and magnetically-driven systems. In this review, recent advancements in various approaches for designing colon targeted drug delivery systems and their pharmaceutical applications are covered with a particular emphasis on formulation technologies.

Abstract
Hepatocellular carcinoma (HCC) is in an urgent need of new, effective therapies to reduce morbidity and mortality. We have previously demonstrated that peptidyl-prolyl cis/trans isomerase Pin1 is a potential target for HCC therapy, due to its pivotal role in HCC development through regulating miRNA biogenesis, and discovered the small molecule API-1 as a novel and specific Pin1 inhibitor. Despite its significant anti-HCC activity, the low water solubility and in vivo bioavailability of API-1 limit its clinical application. To address these issues, we herein developed a liposomal formulation of API-1 to improve API-1 delivery and enhance its anti-HCC efficacy. Methods: We designed and developed a nanoscale liposomal formulation of API-1, named as API-LP. Subsequently, the mean diameter, polydispersity, zeta potential, encapsulation efficiency and thermal properties of the optimization API-LP were characterized. The enhanced anti-HCC activity and the molecular mechanism of API-LP were investigated both in vitro and in vivo. Finally, the safety and pharmacokinetic property of API-LP were evaluated systematically. Results: API-LP had good formulation characteristics and exhibited an enhanced in vitro activity of suppressing proliferation and migration of HCC cells when compared with free API-1. The mechanism study showed that API-LP upregulated miRNA biogenesis via inhibiting Pin1 activity followed by restoring the nucleus-to-cytoplasm export of XPO5. Because of the increased delivery efficiency, API-LP displayed a stronger ability to promote miRNA biogenesis than free API-1. Importantly, API-LP displayed higher systemic exposure than free API-1 in mice without apparent toxicity, resulting in an enhanced tumor inhibition in xenograft mice. Conclusion: The development and assessment of API-LP provide an attractive and safe anti-HCC agent, highlighting the miRNA-based treatment for human cancers.

Pharmaceutics 2019; 11:pharmaceutics11060272. [PMID: 31212607 PMCID: PMC6630419 DOI: 10.3390/pharmaceutics11060272] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2019] [Revised: 06/04/2019] [Accepted: 06/07/2019] [Indexed: 02/04/2023] Open
Abstract
The purpose of this study was to develop an oral proliposomal powder of protein using poly-l-arginine-conjugated 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-poly(ethylene glycol) (DSPE-PEG) (PLD) for enhancing cellular association upon reconstitution and to compare its effects with a non-grafted and PEGylated formulation. Cationic proliposome (CATL), PLD-grafted CATL (PLD-CATL), PEGylated CATL (PEG CATL), and PLD grafted-PEG CATL (PLD-PEG CATL) were prepared and compared. Successful conjugation between poly-l-arginine and DSPE-PEG was confirmed by 1H NMR and FT-IR. PLD was successfully grafted onto the proliposomal powder during the slurry process. Although reconstituted liposomal sizes of CATL and PLD-CATL were increased by agglomeration, PEGylation reduced the agglomeration and increased the encapsulation. The viabilities of cells treated with both CATL and PLD-CATL formulations were low but increased following PEGylation. With regard to cellular association, PLD-CATL enhanced cellular association/uptake more rapidly than did CATL. Upon PEGylation, PEG CATL showed a lower level of cellular association/uptake compared with CATL while PLD-PEG CATL did not exhibit the rapid cellular association/uptake as seen with PLD-CATL. However, PLD-PEG CATL still enhanced the higher cellular association/uptake than PEG CATL did without PLD. In conclusion, proliposomes with PLD could accelerate cellular association/uptake but also caused high cellular toxicity. PEGylation reduced cellular toxicity and also changed the cellular association pattern of the PLD formulation.

Abstract
The use of nanoparticles as a means of targeted delivery of therapeutics and imaging agents could greatly enhance the transport of biologically active contents to specific target tissues, while avoiding or reducing potentially undesired side effects. Generally speaking, the oral route of administration is associated with good patient compliance, as it is convenient, economical, noninvasive, and does not require special training. Here, we review the progress of the utilization of nanodelivery-system carriers or stabilized solid-drug nanoparticles following oral administration, with particular attention on toxicological data. Mechanisms of cytotoxicity are discussed and the problem of extrapolating knowledge to human scenarios highlighted. Additionally, issues associated with administration of drugs via the oral route are underlined, while strategies utilized to overcome these are highlighted. This review aims to offer a balanced overview of strategies currently being used in the application of nanosize constructs for oral medical applications.

Abstract
Self-emulsifying drug–delivery systems (SEDDS) have been widely employed to ameliorate the oral bioavailability of P-glycoprotein (P-gp) substrate drugs and to overcome multidrug resistance in cancer cells. However, the role of formulation aspects in the reduced P-gp activity is not fully understood. In this review, we first explore the role of various SEDDS excipients in the reduced P-gp activity with the main emphasis on the effective excipient concentration range for excipient-mediated modulation of P-gp activity and then we discuss the synergistic effect of various formulation aspects on the excipient-mediated modulation of P-gp activity. This review provides an approach to develop a rationally designed SEDDS to overcome P-gp-mediated drug efflux.

Abstract
The aim of this study was to develop a proliposomal formulation of lipopeptide antibiotic drug daptomycin (DAP) for oral delivery. Thin film hydration was the selected method for preparation of proliposomes. Different phospholipids including soy-phosphatidylcholine (SPC), hydrogenated egg-phosphatidylcholine (HEPC), and distearoyl-phosphatidylcholine (DSPC) were evaluated in combination with cholesterol. The inclusion of surface charge modifiers in the formulation such as dicetyl phosphate (DCP) and stearylamine (SA) to enhance drug encapsulation was also evaluated. Particle size, surface charge, and encapsulation efficiency were performed on daptomycin-hydrated proliposomes as part of physical characterization. USP type II dissolution apparatus with phosphate buffer (pH 6.8) was used for in vitro drug release studies. Optimized formulation was evaluated for in vivo pharmacokinetics after oral administration to Sprague-Dawley rats. Proliposomes composed of SPC exhibited higher entrapment efficiency than those containing HEPC or DSPC. The highest entrapment efficiency was achieved by positively charged SPC-SA proliposomes, showing an encapsulation efficiency of 92% and a zeta potential of + 28 mV. In vitro drug release of optimized formulation demonstrated efficient drug retention totaling for less than 20% drug release within the first 60 min and only 42% drug release after 2 h. Pharmacokinetic parameters after single oral administration of optimized proliposomal formulation indicated a significant increase in oral bioavailability of DAP administered as SPC-SA proliposomes when compared to drug solution. Based on these results, incorporation of charge modifiers into proliposomes may increase drug loading and proliposomes an attractive carrier for oral delivery of daptomycin.

Abstract
The natural product berberine (BBR), present in various plants, arouses great interests because of its numerous pharmacological effects. However, the further development and application of BBR had been hampered by its poor oral bioavailability. In this work, we report on polymer–lipid hybrid nanoparticles (PEG–lipid–PLGA NPs) loaded with BBR phospholipid complex using a solvent evaporation method for enhancing the oral BBR efficiency. The advantage of this new drug delivery system is that the BBR–soybean phosphatidylcholine complex (BBR–SPC) could be used to enhance the liposolubility of BBR and improve the affinity with the biodegradable polymer to increase the drug-loading capacity and controlled/sustained release. The entrapment efficiency of the PEG–lipid–PLGA NPs/BBR–SPC was observed to approach approximately 89% which is more than 2.4 times compared with that of the PEG–lipid–PLGA NPs/BBR. To the best of our knowledge, this is the first report on using polymer material for effective encapsulation of BBR to improve its oral bioavailability. The prepared BBR delivery systems demonstrated a uniform spherical shape, a well-dispersed core-shell structure and a small particle size (149.6 ± 5.1 nm). The crystallographic and thermal analysis has indicated that the BBR dispersed in the PEG–lipid–PLGA NPs matrix is in an amorphous form. More importantly, the enhancement in the oral relative bioavailability of the PEG–lipid–PLGA NPs/BBR–SPC was ∼343% compared with that of BBR. These positive results demonstrated that PEG–lipid–PLGA NPs/BBR–SPC may have the potential for facilitating the oral drug delivery of BBR.
