Abstract
Oral administration of BCS class IV anticancer agents has always remained challenging and frequently results in poor oral bioavailability. The goal of the current study was to develop hybrid nanoparticles (HNPs) employing cholesterol and poloxamer-407 to boost paclitaxel's (PTX) oral bioavailability. A series of HNPs with different cholesterol and poloxamer-407 ratios were developed utilizing a single-step nanoprecipitation technique. The PTX loaded HNPs were characterized systematically via particle size, zeta potential, polydispersity index, surface morphology, in vitro drug release, FTIR, DSC, XRD, acute oral toxicity analysis, hemolysis evaluation, accelerated stability studies, and in vivo pharmacokinetic analysis. The HNPs were found within the range of 106.6±55.60 - 244.5±88.24 nm diameter with the polydispersity index ranging from 0.20±0.03 - 0.51±0.11. SEM confirmed circular, nonporous, and smooth surfaces of HNPs. PTX loaded HNPs exhibited controlled release profile. The compatibility between the components of formulation, thermal stability, and amorphous nature of HNPs were confirmed by FTIR, DSC, and XRD, respectively. Acute oral toxicity analysis revealed that developed system have no deleterious effects on the animals' cellular structures. HNPs demonstrated notable cytotoxic effects and were hemocompatible at relatively higher concentrations. In vivo pharmacokinetic profile (AUC0-∞, AUMC0-∞, t1/2, and MRT0-∞) of the PTX loaded HNPs was improved as compared to pure PTX. It is concluded from our findings that the developed HNPs are hemocompatible, biocompatible and have significantly enhanced the oral bioavailability of PTX.

Abstract
The area of drug delivery systems has witnessed significant advancements in recent years, with a particular focus on improving efficacy, stability, and patient compliance. Transdermal drug delivery offers numerous benefits compared to conventional methods of drug administration through the skin. It helps in avoiding gastric irritation, hepatic first-pass metabolism, and gastric degradation of the drug. It bypasses the gastrointestinal tract, eliminating the risk of first-pass metabolism and allowing drugs to be administered without being affected by pH, enzymes, or intestinal bacteria. Additionally, it allows for sustained release of the drug, is noninvasive, and enhances patient adherence to the treatment regimen. The transdermal drug delivery system (TDDS) can serve as an alternative route for drug administration in individuals who cannot tolerate oral medications, experience nausea, or are unconscious. When compared to intravenous, hypodermic, and other parenteral routes, TDDS stands out due to its ability to eliminate pain, reduce the risk of infection, and prevent disease transmission associated with needle reuse. Consequently, the overall patient compliance is significantly improved with the utilization of TDDS. Among the noteworthy developments are cubosomes and ethosomes, two distinct yet promising carriers that have garnered attention for their unique properties. In conclusion, this review synthesizes the current knowledge on cubosomes and ethosomes, shedding light on their individual strengths and potential synergies. The exploration of their application in various therapeutic areas underscores their versatility and establishes them as key players in the evolving landscape of drug delivery systems.

Statistical optimization of tetrahydrocurcumin loaded solid lipid nanoparticles using Box Behnken design in the management of streptozotocin-induced diabetes mellitus. Saudi Pharm J 2023; 31:101727.

Abstract
In the past, curcumin was the go-to medication for diabetes, but recent studies have shown that tetrahydrocurcumin is more effective. The problem is that it's not very soluble in water or very bioavailable. So, our research aims to increase the bioavailability and anti-diabetic efficacy of tetrahydrocurcumin in streptozotocin-induced diabetic rats by synthesizing tetrahydrocurcumin-loaded solid lipid nanoparticles. Box Behnken Design was employed for the optimization of tetrahydrocurcumin-loaded solid lipid nanoparticles (THC-SLNs). The optimal formulation was determined by doing an ANOVA to examine the relationship between the independent variables (drug-to-lipid ratio, surfactant concentration, and co-surfactant concentration) and the dependent variables (particle size, percent entrapment efficiency, and PDI). Particle size, PDI, and entrapment efficiency all showed statistical significance based on F-values and p-values. The optimized batch was prepared using a drug-to-lipid ratio (1:4.16), 1.21% concentration of surfactant, and 0.4775% co-surfactant (observed with a particle size of 147.1 nm, 83.58 ± 0.838 % entrapment efficiency, and 0.265 PDI, and the values were found very close with the predicted ones. As the THC peak vanishes from the DSC thermogram of the improved formulation, this indicates that the drug has been transformed from its crystalline form into its amorphous state. TEM analysis of optimized formulation demonstrated mono-dispersed particles with an average particle size of 145 nm which are closely related to zetasizer's results. In-vitro release study of optimized formulation demonstrated burst release followed by sustained release up to 71.04% throughout 24 hrs. Increased bioavailability of the adjusted THC-SLN was found in an in vivo pharmacokinetics research with 9.47 folds higher AUC(0-t) compared to plain THC-suspension. Additionally, pharmacodynamic experiments of optimized formulation demonstrated a marked decrease in blood glucose level to 63.7% and increased body weight from 195.8 ± 7.223 to 231.2 ± 7.653 on the 28th day of the study and showed a better anti-diabetic effect than plain drug suspension. Results of stability studies revealed that formulation can be stored for longer periods at room temperature. Tetrahydrocurcumin can be effectively administered by SLN for the treatment of diabetes.

Formulation and Characterization of Ursodeoxycholic Acid Nanosuspension Based on Bottom-Up Technology and Box-Behnken Design Optimization. Pharmaceutics 2023; 15:2037. [PMID: 37631251 PMCID: PMC10458560 DOI: 10.3390/pharmaceutics15082037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 07/17/2023] [Accepted: 07/24/2023] [Indexed: 08/27/2023] Open
Abstract
BACKGROUND Ursodeoxycholic acid (UDCA) is a therapeutic agent used for the treatment of cholestatic hepatobiliary diseases in pediatric patients. It is a bile acid that presents high lipophilicity, and it belongs to Class II of the Biopharmaceutical Classification System (BCS), which exhibits low water solubility and high intestinal permeability, which leads to poor oral absorption. The objective of this work was to design and optimize UDCA nanosuspensions by means of the precipitation-ultrasonication method to improve the solubility, dissolution, and oral bioavailability of UDCA. METHODS A three-level, three-factor Box-Behnken design was used to optimize formulation variables and obtain uniform, small-particle-size UDCA nanosuspensions. The independent variables were: stabilizer percentage (X1), amplitude (X2), and sonication time (X3), and the dependent variable was the particle size (Y1). In the precipitation-ultrasonication method, UDCA was dissolved in acetone:PEG 400 (1:1 v/v) and quickly incorporated into the antisolvent (pre-cooled aqueous dispersion of HPMC E-15 0.3%), by means of intense sonication at 50 W for 5 min, controlling temperature through an ice water bath. The lyophilization efficacy was evaluated by means of a cryoprotective efficacy test, working with 10% maltose at -80 °C. The nanosuspensions were characterized by dynamic light scattering (DLS), X-ray diffraction, and scanning electron microscopy (SEM). The physicochemical stability was determined at 25 °C and 4 °C at 7, 14, 30, and 60 days, and the UDCA content was analyzed via HPLC-UV. An in vitro dissolution assay and an oral bioavailability study were performed in male Wistar rats. RESULTS A significant impact was achieved in the optimized nanosuspension with 0.3% (stabilizer), 50 W (amplitude), and 5 min (sonication time), with a particle size of 352.4 nm, PDI of 0.11, and zeta potential of -4.30 mV. It presented adequate physicochemical stability throughout the study and the UDCA content was between 90% and 110%. In total, 86% of UDCA was dissolved in the in vitro dissolution test. The relative oral bioavailability was similar without significant statistical differences when comparing the lyophilized nanosuspension and the commercial tablet, the latter presenting a more erratic behavior. The pharmacokinetic parameters of the nanosuspension and the commercial tablet were Tmax (1.0 ± 0.9 h vs. 2.0 ± 0.8 h, respectively), Cmax (0.558 ± 0.118 vs. 0.366 ± 0.113 µM, respectively), ΔCmax (0.309 ± 0.099 vs. 0.232 ± 0.056, respectively), AUC (4.326 ± 0.471 vs. 2.188 ± 0.353 µg/mL.h, respectively, p < 0.02), and IAUC0-24h (2.261 ± 0.187 µg/mL.h vs. 1.924 ± 0.440 µg/mL.h, respectively). CONCLUSIONS The developed nanosuspension presents an appropriate dosage and administration for pediatric patients. On the other hand, it exhibits an adequate absorption and UDCA oral bioavailability.

Abstract
The barrier functionalities of the skin offer a major but not insuperable hindrance for fabrication of skin delivery effective systems. This work aimed to develop an optimized lipid polymer hybrid nanoparticle and assess the skin delivery effectiveness of hydrocortisone (9.872 ± 0.361 × 10-3 cm2/h) of a drug through the skin from an optimized formulation when compared with a drug solution. Meanwhile, histological examination after topical application of the optimized formulation showed a safe increase in epidermal thickness. In vivo, the optimized formulation showed promising anti-inflammatory activity in a croton oil-induced ear rosacea model. As an excellent anti-inflammatory agent, these findings propose that the use of lipomers could be a promising strategy to improve the topical effectiveness of hydrocortisone acetate (HCA) against inflammatory diseases. Collectively, these results support our view that lipid polymer hybrid nanoparticles can proficiently deliver hydrocortisone to the skin in treating skin inflammatory conditions.

Abstract
The present study investigated the oral bioavailability of celecoxib when incorporated into solid lipid nanoparticles either dissolved or suspended. In vitro drug release in different media, in vivo performance, and in vitro-in vivo correlation were conducted. The results revealed that the compound was successfully encapsulated into the nanocarriers with good physicochemical properties for oral administration. The in vitro release profiles followed the Weibull model, with significant differences between the formulations containing the solubilized and the suspended compound. Furthermore, in vitro release data could be used to rank the observed in vivo bioavailability. The relative bioavailability of celecoxib from the solid lipid nanoparticles was 2.5- and 1.8-fold higher for the drug solubilized and suspended solid lipid nanoparticle formulation, respectively, when compared to the celecoxib reference. A significant difference was observed between the plasma concentration-time profiles and pharmacokinetic parameters for the three investigated formulations. Finally, this investigation displayed promising outcomes that both solubilized and suspended celecoxib in the lipid core of the solid lipid nanoparticles offers the potential to improve the compound's oral bioavailability and thereby reduce the dosing frequency.

Abstract
Alzheimer's disease (AD) is a neurodegenerative disease that affects a wide range of populations and is the primary cause of death in various countries. The treatment of AD is still restricted to oral conventional medicines that act only superficially. Fabrication of intranasal solid lipid nanoparticulate system for the uptake of therapeutic agents will act as a convincing approach with limited off-site toxicity and increased pharmacological activity. The objective of this study was to formulate, optimize, and evaluate the efficiency of rivastigmine tartrate (RT)-loaded intranasal solid lipid nanoparticles (SLNs) employing the solvent-evaporation diffusion method. To optimize the formulation parameters, the central composite design (CCD) was used. Lipid concentration (X1) and surfactant concentration (X2) were considered to be independent variables, while particle size (Y1), percentage entrapment efficiency (Y2), and percentage drug release (Y3) were considered as responses. The solid lipid was glyceryl monostearate, while the surfactant was polysorbate 80. The optimized formulation has a particle size of 110.2 nm, % entrapment efficiency of 82.56%, and % drug release of 94.86%. The incompatibility of drug excipients was established by differential scanning calorimetry (DSC) and Fourier-transform infrared spectroscopy (FTIR). Nasal histopathology tests on sheep mucosa revealed that the developed SLNs were safe to utilize for intranasal delivery with no toxicity. Ex vivo permeation investigations revealed that the flux and diffusion coefficients for RT solid lipid nanoparticles and RT solution were 3.378 g/cm2 /h and 0.310-3 cm2 /h, respectively. Stability studies demonstrated that the developed SLNs were stable when stored under various storage conditions. The viability and vitality of adopting a lipid particle delivery system for improved bioavailability via the intranasal route were also established in the in vivo pharmacokinetic investigations. According to the histopathological and pharmacokinetic investigations, the developed formulations were safe, non-lethal, efficient, and robust. These results suggest the potentiality provided by rivastigmine tartrate-loaded solid lipid nanoparticles for nasal delivery.

Abstract
Liver fibrosis is a major global health concern. Management of chronic liver disease is severely restricted in clinics due to ineffective treatment approaches. However, a lack of targeted therapy may aggravate this condition. Asiatic acid (AA), a pentacyclic triterpenoid acid, can effectively protect the liver from hepatic disorders. However, the pharmaceutical application of AA is limited by low oral bioavailability and poor targeting efficiency. This study synthesized a novel liver-targeting material from PEG-SA, chemically linked to ursodeoxycholic acid (UA), and utilized it to modify AA nanostructured lipid carriers (UP-AA-NLC) with enhanced targeting and improved efficacy. The formulation of UP-AA-NLC was optimized via the Box–Behnken Experimental Design (BBD) and characterized by size, zeta potential, TEM, DSC, and XRD. Furthermore, in vitro antifibrotic activity and proliferation of AA and NLCs were assessed in LX-2 cells. The addition of UP-AA-NLC significantly stimulated the TGF-beta1-induced expression of α-SMA, FN1, and Col I α1. In vivo near-infrared fluorescence imaging and distribution trials in rats demonstrated that UP-AA-NLC could significantly improve oral absorption and liver-targeting efficiency. Oral UP-AA-NLC greatly alleviated carbon tetrachloride-induced liver injury and fibrosis in rats in a dosage-dependent manner, as reflected by serum biochemical parameters (AST, ALT, and ALB), histopathological features (H&E and Masson staining), and antioxidant activity parameters (SOD and MDA). Also, treatment with UP-AA-NLC lowered liver hydroxyproline levels, demonstrating a reduction of collagen accumulation in the fibrotic liver. Collectively, optimized UP-AA-NLC has potential application prospects in liver-targeted therapy and holds great promise as a drug delivery system for treating liver diseases.

Lamotrigine loaded PLGA nanoparticles intended for direct nose to brain delivery in epilepsy: pharmacokinetic, pharmacodynamic and scintigraphy study. ARTIFICIAL CELLS, NANOMEDICINE, AND BIOTECHNOLOGY 2021; 49:511-522.

Abstract
The present study aimed to investigate the brain targeting efficacy of Lamotrigine (LTG) loaded PLGA nanoparticles (LTG-PNPs) upon intranasal administration. LTG-PNPs were fabricated through the emulsification-solvent evaporation technique and evaluated for % Entrapment efficiency, particle size, in-vitro release, surface morphology, crystallinity, ex-vivo permeation & thermal behaviour. Biodistribution, gamma scintigraphy, and pharmacodynamic studies were performed in BALB/c mice, New Zealand rabbits, and Wistar rats respectively. LTG-PNPs exhibited % EE 71%; particle size 170.0 nm; Polydispersity index 0.191; zeta potential -16.60 mV. LTG-PNPs exhibited a biphasic release pattern. Biodistribution and gamma scintigraphy studies proved a greater amount of LTG in the brain following intranasal delivery of LTG-PNPs in comparison to LTG-SOL. Pharmacodynamic studies demonstrated delayed seizure onset time with LTG-PNPs in comparison to LTG-SOL. Intranasal administration of LTG-PNPs provided prolonged release, higher bioavailability, and better brain targeting bypassing the BBB. The developed formulation could be administered as a once-a-day formulation that would reduce the dosing frequency; dose; dose-related side effects; cost of the therapy and would be beneficial in the management of epilepsy as compared to the LTG-SOL. However, the proof of concept generated through these studies needs to be further validated in higher animals and human volunteers.

Abstract
In this study, a Venturi tube is proposed as an efficient static mixer incorporated into a continuous recirculation system for obtaining solid lipid nanoparticles (SLN) of monoolein. The device's operating principle consists of producing a turbulent flux in the throat of a Venturi tube. Taking advantage of this effect SLN of monoolein were obtained by rapid diffusion of the organic phase into the aqueous phase (stabilizer), causing lipid aggregation on the nanometric particles. The main aim of the present study was to evaluate the critical factors for obtaining the SLN of monoolein in order to control the independent variables of this methodology. A Box-Behnken design was used to study such independent variables (factors) as injection rate (X1), recirculation rate (X2), and stabilizer (X3) on the dependent variables; namely, process yield (Y1), particle size (Y2), polydispersity index (Y3) and zeta potential (Y4). The optimum operating conditions for preparing SLN were: injection rate, 1.6 mL/min; recirculation rate, 4.2 L/min; and stabilizer concentration, 1.0 w/v, with a value of D = 0.84. The predicted responses of the particle size were 212.0 nm, with a polydispersity index of 0.21, a zeta potential of -19.9 mV, and a process yield of 96.0%. Under the same operating condition, SLN formed with different lipids and stabilizers were obtained with nanometric size and zeta potential of ∼ -30.0 mV. Results show that the Venturi tube method (VTM) is an innovative and versatile technique for preparing SLN of nanometric size with high process yields through a turbulent flow.

Abstract
We prepared nanostructured lipid carriers (NLC) to promote skin permeation of Corylin so that it can increase its effect on photoaging. Corylin-NLCs were prepared and characterized based on morphology, particle size, zeta potentials, FTIR and DSC. In vitro, we assess the cytotoxicity and lactate dehydrogenase (LDH) of HaCaT cells irradiated by UVB. Expression of antioxidant enzymes was evaluated by commercial kits. The effects of Corylin-NLC on apoptosis were confirmed by flow cytometry and western blotting. In vivo, we use UV irradiated mouse as the oxidative stress model to assess the therapeutic effect of Corylin loaded NLC gel. We identified the Corylin-NLCs can significantly suppress the LDH release, decrease MDA content, increase in CAT, SOD, GSH-Px activity, increase the expression of Bcl-2/Bax protein and reduce the expression of cleaved caspase-3/caspase-3 protein on UVB induced HaCaT cells. The histopathological lesions were significantly improved and observably decreased MDA level, increase in antioxidant enzymes activity in serum of mice by pretreatment of Corylin-NLCs gel. Overall, this study proposes a promising strategy for improving the therapeutic efficacy of photoaging.

Abstract
Due to poor bioavailability and chemical instability, the effectiveness of curcumin is negligible in the treatment of numerous diseases. Solid lipid nanoparticles (SLNs) increase the bioavailability of lipophilic compounds and protect the drug from gastrointestinal degradation. The objective of our study is the utilization of SLNs to improve the pharmacokinetics and pharmacodynamics of curcumin in the management of diabetes mellitus. Central composite design was used to prepare curcumin-loaded SLNs (Cur-SLN). The analysis of independent variables like drug concentration, lipid concentration, and surfactant concentration was carried out using analysis of variance (ANOVA) to obtain the optimized batch (optimized Cur-SLN) having the desired values of dependent variables particle size and entrapment efficiency. In vitro release, differential scanning calorimeter (DSC), transmission electron microscopy (TEM), and Fourier Transform Infra-Red (FTIR) studies of optimized Cur-SLN were carried out and then its pharmacokinetic and pharmacodynamic studies were performed. The model was found to be significant for particle size and entrapment efficiency based on F-value and p-value. The optimized batch's predicted values were in close agreement with the actual values of particle size and entrapment efficiency. TEM results confirm mono-dispersion and spherical shape of particles in the formulation. The DSC results confirmed the changing of drug from crystalline to amorphous form. Burst release followed by the sustained release was obtained in the in vitro release studies. The pharmacokinetic study shows enhanced bioavailability of optimized Cur-SLN compared with a plain drug suspension. The optimized Cur-SLN achieved higher antidiabetic activity in streptozotocin-induced diabetes mellitus rats than the plain drug suspension. SLNs can be used as a promising technique for delivering curcumin in the management of diabetes mellitus.

Abstract
Nanotechnology has been widely applied to develop drug delivery systems to improve therapeutic performance. The effectiveness of these systems is intrinsically related to their physicochemical properties, so their biological responses are highly susceptible to factors such as the type and quantity of each material that is employed in their synthesis and to the method that is used to produce them. In this context, quality-oriented manufacturing of nanoparticles has been an important strategy to understand and to optimize the factors involved in their production. For this purpose, Design of Experiment (DoE) tools have been applied to obtain enough knowledge about the process and hence achieve high-quality products. This review aims to set up the bases to implement DoE as a strategy to improve the manufacture of nanocarriers and to discuss the main factors involved in the production of the most common nanocarriers employed in the pharmaceutical field.

Abstract
OBJECTIVE Perphenazine (PPZ), as a typical antipsychotic medical substance, has the same effectiveness compared to atypical antipsychotic medications for the treatment of schizophrenia. Despite the lipophilic essence, PPZ encounters limited bioavailability caused by the first-pass metabolism following oral administration. In the present study, PPZ-containing solid lipid nanoparticles (PPZ-SLNs) were prepared and optimized based on different factors, including lipid and surfactant amount, to develop appropriate and safe novel oral dosage forms of PPZ. METHODS The solvent emulsification-evaporation method was utilized to form SLNs by using soybean lecithin, glycerol monostearate (GMS), and Tween 80. Statistical optimization was done by the Box-Behnken design method to achieve formulation with optimized particle size, entrapment efficiency, and zeta potential. Also, transmission electron microscopy, in vitro release behavior, differential scanning calorimetry (DSC), and powder X-ray diffractometry (P-XRD) studies and cytotoxicity studies were assessed. RESULTS Optimization exhibited the significant effect of various excipients on SLN characteristics. Our finding indicated that the mean particle size, zeta potential, and entrapment efficiency of optimized PPZ-SLN were, respectively, 104 ± 3.92 nm, -28 ± 2.28 mV, and 83% ± 1.29. Drug release of PPZ-SLN was observed to be greater than 90% for 48 h that emphasized a sustained-release pattern. The DSC and P-XRD studies revealed the amorphous state of PPZ-SLN. FTIR spectra showed no incompatibility between the drug and the lipid. Performing cytotoxicity studies indicated no significant cytotoxicity on HT-29 cell culture. CONCLUSION Our study suggests that PPZ-SLNs can make a promising vehicle for a suitable therapy of schizophrenia for the oral drug delivery system.

Abstract
The aim of this research was to study the effect of marketed tablet (Crestor®) powder suspension (MTPS) and nanoparticle formulation of rosuvastatin calcium (RC) on the pharmacokinetic (PK) and pharmacodynamic (PD) parameters in hyperlipidemia rats. The hyperlipidemia is induced by intraperitoneal injection of Triton-X-100 in 0.9 %w/v saline solution. The marketed tablet was dispersed into suspension. The RC loaded nanoparticles (RC-NPs) are prepared by homogenization method. The prepared RC-NP formulation was characterized for size, drug excipient compatibility and crystallization by differential scanning calorimeter (DSC), morphology by SEM, stability at room temperature, in-vitro dissolution and in-situ absorption in rats. Further, the pharmacokinetic and pharmacodynamic studies were conducted in hyperlipidemia rats. The size of the RC-NP formulation was found to be 183.4 ± 4.5 nm and to be nearly spherical by SEM. DSC studies revealed that no interaction and RC converted to amorphous form in RC-NP formulation. RC-NP formulation was physically and chemically stable over two months at room temperature. The drug release was found to be 25.8 ± 2.5 and 89.96 ± 2.8 % in five mins, respectively from MTPS and RC-NP formulations. The Peff of MTPS and NP of RC was 1.8 ± 0.2 × 10-5 and 2.7 ± 0.3 × 10-5 cm/s, respectively. From the PK studies, the enhancement in the oral bioavailability was found to be 2.4-folds when compared to MTPS formulation and statistically significant (p < 0.05). PD study of RC-NP formulation in hyperlipidemic rats exhibited decrease in lipid profile for 24 h, while MTPS exhibited a decrease in lipid profile for 12 h. Therefore, the results conclusively demonstrate the nanoparticles of RC showed significant enhancement in the PK and PD parameters.

Abstract
OBJECTIVE The main scope of the present investigation was to improve the bioavailability of perphenazine (PPZ) by incorporating it into the nanostructured lipid carriers (NLCs). SIGNIFICANCE As a result of lipophilic nature and poor aqueous solubility, as well as extensive hepatic metabolism, PPZ has low systemic bioavailability via the oral route. NLCs have shown potentials to surmount the oral delivery drawbacks of poorly water-soluble drugs. METHODS The PPZ-NLCs were prepared by the emulsification-solvent evaporation method and subjected for particle size, zeta potential, and entrapment efficiency (EE) analysis. The optimized NLCs were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and powder X-ray diffractometry (PXRD). Besides, in vitro release behavior, storage stability, and pharmacokinetic studies followed by a single-dose oral administration in rats were performed. RESULTS Optimized PPZ-NLCs showed a particle size of less than 180 nm with appropriate EE of more than 95%. Microscopic images captured with SEM and TEM exhibited that NLCs were approximately spherical in shape. DSC and PXRD analysis confirmed reduced crystallinity of PPZ after incorporation in NLCs. FTIR spectra demonstrated no chemical interactions between PPZ and NLC components. In vitro release studies confirmed the extended-release properties of NLC formulations. PPZ-NLCs exhibited good stability at 4 °C within three months. The oral bioavailability of NLC-6 and NLC-12 was enhanced about 3.12- and 2.49-fold, respectively, compared to the plain drug suspension. CONCLUSION NLC can be designated as an effective nanocarrier for oral delivery of PPZ.

Abstract
A rapid, simple, sensitive, and selective liquid chromatography-tandem mass spectrometry (LC-MS) test method was developed and validated for the trace level determination of 4-chlorobutyl-(S)-[4-chloro-2-(4-cyclopropyl-1,1,1-trifluoro-2-hydroxy-but-3yn-2-yl)phenyl] carbamate (4-CTHC). 4-CTHC is a potential genotoxic impurity in efavirenz drug substance and the acceptable level is 2.5 μg ml-1 with respect to analyte concentration according to ICH M7(R1) Multidisciplinary Guidelines M7(R1). The LC-MS/MS analysis of 4-CTHC impurity was carried out on a Kinetex C18 (150 × 4.6 mm, 5.0 μm) column. In this test procedure, the mobile phase was prepared with buffer (0.1% formic acid in water) and acetonitrile in the ratio of 1:3 (v/v). The method set flow rate was 0.4 ml min-1 . The method was developed with a short run time of <10 min. Selective ion monitoring acquisition mode and negative polarity electrospray ionization mode were used as an MS method to quantify genotoxic impurities at 422.25 Da. The method showed linearity in a range of 0.64-3.71 μg ml-1 with a correlation coefficient of 0.9992. The RSD for intra-day and inter-day precision was found to be <5%. The method's accuracy was in the range of 106.5-112.4% for the genotoxic impurity of 4-CTHC. The procedure was validated as per the current ICH Q2 (R1) guidelines and proved suitable for stability testing in the quality control laboratory for pharmaceutical preparations.

Abstract
OBJECTIVE The present work focuses on improving zaleplon (ZAP) performance through nanosizing its insoluble particles which were then delivered intranasally in powder form. SIGNIFICANCE Since nanopowders have an exceptional ability to cross cell membrane, their absorption is facilitated in the solid form. Hence, delivering insoluble ZAP nanocrystals (NC) through intranasal route improves its bioavailability due to both nanosization and the escape of hepatic metabolism. METHODS Nanocrystals were prepared by anti-solvent precipitation followed by probe sonication in presence of Soluplus®, Poloxamer-188 (0.25%), sodium lauryl sulfate (0.5%), and mannitol. Physicochemical evaluation of the prepared NC was done by DSC and XRPD. TGA was performed for stability detection. Ex vivo permeation study through isolated cattle nasal mucosal membrane, in addition to an in vivo bioavailability study was performed for assessment of the prepared NC. RESULTS Nanosization to 200 nm contributed to the enhancement in dissolution ∼100% within 30 min and reduced half-life to 1.63 min. Confirmation of adsorption of polymers over NC' surface was elucidated. TGA confirmed their thermal stability. Ex vivo permeation study showed a 2.7 enhancement ratio in favor of the prepared NC. Both the extent and rate of NC absorption through nasal mucosa of rabbits were significantly higher (p ˂ .05) than in case of oral tablets. The relative bioavailability of NC was increased 3.14 times as compared to the Sleep aid® tablets. CONCLUSION The intranasal delivery of nanoscale ZAP powder proved to be a successful alternative to oral formulations that suffer poor absorption and limited bioavailability.

Polymeric nanoencapsulation of zaleplon into PLGA nanoparticles for enhanced pharmacokinetics and pharmacological activity. Biopharm Drug Dispos 2021; 42:12-23. [PMID: 33320969 PMCID: PMC7898708 DOI: 10.1002/bdd.2255] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2020] [Revised: 11/18/2020] [Accepted: 11/25/2020] [Indexed: 12/22/2022]
Abstract
Zaleplon (ZP) is a sedative and hypnotic drug used for the treatment of insomnia. Despite its potent anticonvulsant activity, ZP is not commonly used for the treatment of convulsion since ZP is characterized by its low oral bioavailability as a result of poor solubility and extensive liver metabolism. The following study aimed to formulate specifically controlled release nano-vehicles for oral and parenteral delivery of ZP to enhance its oral bioavailability and biological activity. A modified single emulsification-solvent evaporation method of sonication force was adopted to optimize the inclusion of ZP into biodegradable nanoparticles (NPs) using poly (dl-lactic-co-glycolic acid) (PLGA). The impacts of various formulation variables on the physicochemical characteristics of the ZP-PLGA-NPs and drug release profiles were investigated. Pharmacokinetics and pharmacological activity of ZP-PLGA-NPs were studied using experimental animals and were compared with generic ZP tablets. Assessment of gamma-aminobutyric acid (GABA) level in plasma after oral administration was conducted using enzyme-linked immunosorbent assay. The maximal electroshock-induced seizures model evaluated anticonvulsant activity after the parenteral administration of ZP-loaded NPs. The prepared ZP-PLGA NPs were negatively charged spherical particles with an average size of 120-300 nm. Optimized ZP-PLGA NPs showed higher plasma GABA levels, longer sedative, hypnotic effects, and a 3.42-fold augmentation in oral drug bioavailability in comparison to ZP-marketed products. Moreover, parenteral administration of ZP-NPs showed higher anticonvulsant activity compared to free drug. Oral administration of ZP-PLGA NPs achieved a significant improvement in the drug bioavailability, and parenteral administration showed a pronounced anticonvulsant activity.

Int J Pharm 2020; 595:120181. [PMID: 33359537 DOI: 10.1016/j.ijpharm.2020.120181] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Revised: 11/27/2020] [Accepted: 12/11/2020] [Indexed: 02/04/2023]
Abstract
There is an unmet medical need for non-toxic and effective radiation countermeasures for prevention of radiation toxicity during planned exposures. We have earlier shown that intraperitoneal administration of baicalein (BCL) offers significant survival benefit in animal model. Safety, tolerability, pharmacokinetics (PK) and pharmacodynamics of baicalein has been reported in pre-clinical model systems and also in healthy human volunteers. However, clinical translation of baicalein is hindered owing to poor bioavailability due to lipophilicity. In view of this, we fabricated and characterized in-situ solid lipid nanoparticles of baicalein (SLNB) with effective drug entrapment and release kinetics. SLNB offered significant protection to murine splenic lymphocytes against 4 Gy ionizing radiation (IR) induced apoptosis. Oral administration of SLNB exhibited ~70% protection to mice against whole body irradiation (WBI 7.5 Gy) induced mortality. Oral relative bioavailability of BCL was enhanced by over ~300% after entrapment in the SLNB as compared to BCL. Oral dosing of SLNB resulted in transient increase in neutrophil abundance in peripheral blood. Interestingly, we observed that treatment of human lung cancer cells (A549) with radioprotective dose of SLNB exhibited radio-sensitization as evinced by decrease in survival and clonogenic potential. Contrary to antioxidant nature of baicalein in normal cells, SLNB treatment induced significant increase in cellular ROS levels in A549 cells probably due to higher uptake and inhibition of TrxR. Thus, a pharmaceutically acceptable SLNB exhibited improved bioavailability, better radioprotection to normal cells and sensitized cancer cells to radiation induced killing as compared to BCL suggesting its possible utility as an adjuvant during cancer radiotherapy.

Abstract
BACKGROUND Perphenazine (PPZ) is a typical antipsychotic that is mainly administrated for the treatment of schizophrenia. Due to its highly lipophilic nature and extensive hepatic first-pass metabolism, its oral bioavailability is low (40%). OBJECTIVE The novel nanocarriers like solid lipid nanoparticles (SLN) have been reported to be highly effective for improving the therapeutic effect of drugs. Therefore the main scope of the present investigation was the evaluation of in vivo characteristics of PPZ-SLN in terms of pharmacokinetic parameters and brain distribution. METHODS The PPZ-SLN was prepared by the solvent-emulsification and evaporation method. The storage stability of PPZ-SLN and empty SLN powders was studied for 3 months. In vivo pharmacokinetic studies and brain distribution evaluations were performed following a single oral dose administration of PPZ and PPZ-SLN suspensions on male Wistar rats. An HPLC method was established and validated for the quantitative determination of PPZ in plasma and brain samples. RESULTS The storage stability studies revealed the good storage stability of the both PPZ-SLN and empty SLN at 4 °C. Compared to PPZ suspension, the relative bioavailability and the brain distribution of PPZ-SLN were increased up to 2-fold and 16-fold, respectively. Mean residence time (MRT) and half-life (t1/2) of PPZ-SLN were significantly (p value < 0.01) increased in both plasma and brain homogenate compared to PPZ suspension. CONCLUSION The significant improvement in the pharmacokinetic properties of PPZ following one oral dose indicates that SLN is a promising drug delivery system for PPZ and shows a high potential for successful brain delivery of this antipsychotic.

Abstract
BACKGROUND Zotepine (ZT) is a substituted dibenzothiepine tricyclic molecule and second generation antipsychotic drug. It is available as the parenteral and oral solid dosage form, but, orally administered ZT has a poor oral bioavailability (10%) that might be due to either poor water solubility, high lipophilicity (Log P 4) and also first-pass hepatic metabolism. OBJECTIVE The oral bioavailability of ZT was improved by loading into a nanostructured lipid carriers (NLCs) system. METHODS Hot homogenization with probe sonication method was used for the preparation of ZT-NLCs formulations and characterized for an optimal system based on physicochemical characteristics and in vitro release. Differential scanning calorimetry (DSC), X-ray diffraction (XRD) analysis, and scanning electron microscopy (SEM) studies were used to confirm the crystalline nature and shape of the optimized ZT-NLC formulation. The physical stability of the optimized ZT-NLC formulation was evaluated at the refrigerator and room temperature over two months. Furthermore, in vivo pharmacokinetic (PK) studies of optimized ZT-NLC and ZT coarse suspension (ZT-CS) as control formulation, were conducted in male Wistar rats. RESULTS The optimized formulation of ZT-NLC showed Z-avg, PDI, ZP of 145.8 ± 2.5 nm, 0.18 ± 0.05, -31.6 ± 1.8 mV, respectively. In vitro release studies indicated the sustained release of ZT. DSC and XRD studies revealed the conversion of ZT into an amorphous form. SEM studies showed the spherical shape of the ZT-NLC formulation. PK studies showed 1.8-folds improvement (p<0.05) in oral bioavailability when compared with ZTCS formulation. CONCLUSION Overall, the results established that NLCs could be used as a new alternative delivery vehicle for the oral delivery of ZT.

Abstract
In the golden age of pharmaceutical nanocarriers, we are witnessing a maturation stage of the original concepts and ideas. There is no doubt that nanoformulations are extremely valuable tools for drug delivery applications; the current challenge is how to optimize them to ensure that they are safe, effective and scalable, so that they can be manufactured at an industrial level and advance to clinical use. In this context, lipid nanoparticles have gained ground, since they are generally regarded as non-toxic, biocompatible and easy-to-produce formulations. Pharmaceutical applications of lipid nanocarriers are a burgeoning field for the transport and delivery of a diversity of therapeutic agents, from biotechnological products to small drug molecules. This review starts with a brief overview of the characteristics of solid lipid nanoparticles and discusses the relevancy of performing systematic preformulation studies. The main applications, as well as the advantages that this type of nanovehicles offers in certain therapeutic scenarios are discussed. Next, pharmacokinetic aspects are described, such as routes of administration, absorption after oral administration, distribution in the organism (including brain penetration) and elimination processes. Safety and toxicity issues are also addressed. Our work presents an original point of view, addressing the biopharmaceutical aspects of these nanovehicles by means of descriptive statistics of the state-of-the-art of solid lipid nanoparticles research. All the presented results, trends, graphs and discussions are based in a systematic (and reproducible) bibliographic search that considered only original papers in the subject, covering a 7 years range (2013-today), a period that accounts for more than 60% of the total number of publications in the topic in the main bibliographic databases and search engines. Focus was placed on the therapeutic fields of application, absorption and distribution processes and current efforts for the translation into the clinical practice of lipid-based nanoparticles. For this, the currently active clinical trials on lipid nanoparticles were reviewed, with a brief discussion on what achievements or milestones are still to be reached, as a way of understanding the reasons for the scarce number of solid lipid nanoparticles undergoing clinical trials.

Abstract
Ketoconazole (KZ) is broad spectrum antifungal drug, used for the treatment of fungal infections. KZ's clinical topical use has been associated with some adverse effects in healthy adults particularly local reactions, such as stinging, severe irritation, and pruritus. However, bioavailability of KZ after oral administration is low from tablets due to its low aqueous solubility. The objective of this investigation was development and characterization of KZ-containing solid lipid nanoparticles (KZ-SLNs) and SLN-containing hydrogel (KZ-SLN-H) for oral and topical delivery of KZ. KZ-SLNs were prepared using homogenization-sonication method. Optimal KZ-SLN formulation was selected based on physicochemical and in-vitro release studies. Optimized KZ-SLN converted to KZ-SLN hydrogel (KZ-SLN-H) using gelling polymers and optimized with rheological and in-vitro studies. Further, optimized KZ-SLN and KZ-SLN-H formulations evaluated for crystallinity, morphology, stability, ex-vivo and in-vivo pharmacokinetic (PK) studies in rats, comparison with KZ suspension (KZ-S) and KZ-S hydrogel (KZ-SH). Optimized KZ-SLN formulation showed desirable characters. KZ-SLN and KZ-SLN-H formulations exhibited spherical shape, converted to amorphous, sustained release behaviour and enhanced permeability (p < 0.05). Moreover, both formulations were stable for three months at 4 °C and 25 °C. PK studies revealed 1.9 and 1.5-folds, 3.5 and 2.8-folds enhancement of bioavailability of optimized KZ-SLN and KZ-SLN-H formulations (p < 0.05) compared with KZ-S and KZ-SH formulations, respectively. Overall, SLN and SLN-H formulations could be considered as an efficient delivery vehicles for KZ through oral and topical administration for better control over topical and systemic fungal infections.

Abstract
Abstract
Background
The purpose of this work was to prepare and evaluate the zotepine (ZT) loaded solid lipid nanoparticles (SLNs) that might improve the oral bioavailability. ZT is an anti-psychotic drug used for the treatment of schizophrenia. Currently, it is available as parenteral and oral dosage form. But, ZT has a poor oral bioavailability of about 7–13% due to limited aqueous solubility and first-pass effect. ZT-SLNs were developed using homogenization method and characterized for optimal system based on physicochemical characteristics and in vitro release. The optimized ZT-SLNs were evaluated for permeation through rat intestine using evert sac method. The crystalline nature of the ZT-SLNs was studied using DSC and XRD analysis. Surface morphology studies were conducted using SEM. Physical stability of the optimized ZT-SLN was evaluated at refrigerator and room temperature over 2 months. Further, pharmacokinetic (PK) studies of ZT-SLN were conducted in male Wistar rats, in comparison with ZT coarse suspension (ZT-CS), in vivo.
Results
Among all the developed ZT-SLN formulations, optimized formulation (F1) showed Z-avg, PDI, and ZP of 104.3 ± 1.6 nm, 0.17 ± 0.01, and − 30.5 ± 2.5 mV, respectively. In vitro release and permeation studies exhibited 82.9 ± 1.6% of drug release and 19.6 ± 2.1% of percentage drug permeation over 48 h and 120 min, respectively. DSC and XRD studies revealed the conversion of ZT to amorphous form. SEM studies showed spherical shape with improved PDI of ZT-SLN formulation. PK studies showed a significant (p < 0.05) improvement in AUC of about 1.3-fold, in comparison with ZT-CS in Wistar rats.
Conclusion
Therefore, the results concluded that SLNs could be considered as a new alternative delivery system for the enhancement of oral bioavailability of ZT.

Abstract
Bacterial endophthalmitis (BE) is a potentially sight-threatening inflammatory reaction of the intraocular fluids or tissues caused by bacteria. Ciprofloxacin (CIP) eye drops are prescribed as first-line therapy in BE. However, frequent administration is necessary due to precorneal loss and poor ocular bioavailability. The objective of the current research was to prepare CIP containing nanostructured lipid carriers (CIP-NLCs) loaded an in situ gel system (CIP-NLC-IG) for topical ocular administration for enhanced and sustained antibacterial activity in BE treatment. CIP-NLCs were prepared by the hot homogenization method and optimized based on physicochemical characteristics and physical stability. The optimized CIP-NLC formulation was converted into CIP-NLC-IG with the addition of gellan gum as a gelling agent. Furthermore, optimized CIP-NLC and CIP-NLC-IG were evaluated for in vitro release and ex vivo transcorneal permeation studies, using commercial CIP ophthalmic solution (CIP-C) as the control. The optimized CIP-NLC formulation showed particle size, polydispersity index, zeta potential, assay and entrapment efficiency of 193.1 ± 5.1 nm, 0.43 ± 0.01, -32.5 ± 1.5 mV, 99.5 ± 5.5 and 96.3 ± 2.5%, respectively. CIP-NLC-IG with 0.2% w/v gellan gum showed optimal viscoelastic characteristics. The in vitro release studies demonstrated sustained release of CIP from CIP-NLC and CIP-NLC-IG formulations over a 24 h period. Transcorneal flux and permeability increased 4 and 3.5-fold, and 2.2 and 1.9-fold from CIP-NLC and CIP-NLC-IG formulations, respectively, when compared to CIP-C. The results demonstrate that CIP-NLC-IG could be considered as an alternate delivery system to prolong the residence time on the ocular surface after topical administration. Thus, the current CIP ophthalmic formulations may exhibit improved ocular bioavailability and prolonged antibacterial activity, which may improve therapeutic outcomes in the treatment of BE.

Abstract
Objective: The objective of the present research is to formulate solid lipid nanoparticles (SLN) of CH to improve its oral bioavailability.Methods: Cinnacalcet hydrochloride (CH) exhibits poor oral bioavailability of 20 to 25% because of low aqueous solubility and first pass metabolism. The SLN formulations were optimized using Box-Behnken Design. SLN formulation was prepared using hot homogenization technique followed by ultra-sonication and evaluated. The optimized SLN formulation was lyophilized to improve the stability of the formulation further.Results: Compritol 888 ATO (COM), Soya lecithin (SL) and poloxamer 188 (POL) were selected as lipid, surfactant and co-surfactant respectively. For optimistaion, the desirable goal was fixed for variour responses vis-a-vis entrapment efficiency (EE), particle size (PS) and (time taken for diffusion of 85% drug) T85%. The optimized single dose of SLN obtained using BBD consisting of 30 mg of CH, 100 mg of COM, 150 mg of SL and 0.1% w/v of POL. The pharmacokinetic study revealed that optimized SLN and lyophilized SLN were found to increase the oral bioavailability nearly two times compared to an aqueous suspension of pure drug.Conclusion: Thus lyophilized SLN formulation explicated the potential of lipid-based nanoparticles as a potential carrier in improving the oral delivery and stability of CH.

Abstract
Parkinson’s disease (rp) is a progressive neurodegenerative disorder. Ropinirole (RP) is a newer generation dopamine agonist used for the treatment of PD. It is prescribed as oral dosage form. However, limited oral bioavailability and frequent dosing limits the RP usage. The objective of the current investigation was to develop, optimize, evaluate pharmacokinetic (PK) and pharmacodynamic (PCD) activity of RP loaded solid lipid nanoparticles (RP-SLNs) and nanostructured lipid carriers (RP-NLCs) and containing hydrogel (RP-SLN-C and RP-NLC-C) formulations for improved oral and topical delivery. RP loaded lipid nanoparticles were optimized and converted to hydrogel using carbopol 934 as the gelling polymer. PK and PCD studies in haloperidol-induced PD were conducted in male Wistar rats. In vitro and ex vivo permeation studies showed sustained release profile and enhanced permeation compared with control formulations. Differential scanning calorimeter and X-ray diffraction studies revealed amorphous transformation; scanning electron microscope showed the spherical shape of RP in lipid nanoparticles. PK studies showed 2.1 and 2.7-folds enhancement from RP-SLN and RP-NLC from oral administration, 3.0 and 3.3-folds enhancement from RP-SLN-C and RP-NLC-C topical administration, compared with control formulations, respectively. RP-SLN-C and RP-NLC-C showed 1.4 and 1.2-folds topical bioavailability enhancement compared with RP-SLN and RP-NLC oral administration, respectively. PCD studies showed enhanced dopamine, glutathione, catalase levels and reduced lipid peroxidation levels, compared with the haloperidol-induced PD model. Overall, the results demonstrated that lipid nanoparticles and corresponding hydrogel formulations can be considered as an alternative delivery approach for the improved oral and topical delivery of RP for the effective treatment of PD.

Abstract
In this present research, work quality by design-enabled development of cinacalcet HCl (CH)-loaded solid self-nanoemulsifying drug delivery system (S-SNEDDS) was conducted using a porous carrier in order to achieve immediate drug release and better oral bioavailability. Capmul MCM (CAP), Tween 20 (TW 20) and Transcutol P (TRP) were selected as excipients. Cumulative % drug release at 30 min (Q30), emulsification times (ET), mean globule size (GS) and polydispersity index (PDI) were identified as critical quality attributes (CQAs). Factor mode effect analysis (FMEA) and Taguchi screening design were applied for screening of factors. The optimised single dose of S-SNEDDS obtained using Box-Behnken design (BBD) consisted of 30 mg of CH, 50 mg of CAP, 149.75 mg of TW 20, 55 mg of TRP and 260.75 mg of Neusilin US2. It showed an average Q30 of 97.6%, ET of 23.3 min, GS of 89.5 nm and PDI of 0.211. DSC, XRD and SEM predict the amorphous form of S-SNEDDS. In vivo pharmacokinetic study revealed better pharmacokinetic parameters of S-SNEDDS. The above study concluded that the optimised S-SNEDDS is effective to achieve the desired objective.

Abstract
Domperidone (DOP) is extensively applied orally in the management of nausea and vomiting. Upon oral administration, its bioavailability is very poor due to its poor solubility in alkaline media. Therefore, the aim of this work was to investigate DOP-loaded solid lipid nanoparticles (DOP-SLNs) in order to sustain its release pattern and to enhance oral bioavailability. DOP-SLNs were prepared using four different lipids. Prepared DOP-SLNs were characterized for "polydispersity index (PDI), particle size, zeta potential, % entrapment efficiency (% EE), and drug release behavior." Differential scanning calorimetry (DSC) study was carried out to illustrate the physical form of DOP and excipients. The morphology of DOP-SLNs was confirmed by scanning electron microscopy (SEM). Pharmacokinetic study on optimized DOP-SLN in comparison to tablet was performed in rats. The "particle size, PDI, zeta potential, and % EE" of optimized formulation (F5) were recorded as 201.4 nm, 0.071, - 6.2 mV, and 66.3%, respectively. DSC thermograms suggested amorphous state of DOP in various SLNs. Surface morphology of SLNs using SEM suggested spherical shape of the nanoparticles within nanometer size range. In vitro release studies confirmed that all SLN formulations possessed a sustained release over a period of 12 h (51.3% from optimized formulation) in comparison with immediate release from conventional tablets (100% after 90 min). Pharmacokinetic study showed significant enhancement in oral absorption of DOP from optimized SLN in comparison with DOP tablet. The enhancement in relative bioavailability of DOP from optimized SLN was 2.62-fold in comparison with DOP tablet.

Development and optimization of methotrexate-loaded lipid-polymer hybrid nanoparticles for controlled drug delivery applications. Int J Pharm 2017; 533:156-168.

Abstract
Lipid-polymer hybrid nanoparticles (LPHNPs) are emerging platforms for drug delivery applications. In the present study, methotrexate loaded LPHNPs consisted of PLGA and Lipoid S100 were fabricated by employing a single-step modified nanoprecipitation method combined with self-assembly. A three factor, three level Box Behnken design using Design-Expert® software was employed to access the influence of three independent variables on the particle size, drug entrapment and percent drug release. The optimized formulation was selected through numeric optimization approach. The results were supported with the ANOVA analysis, regression equations and response surface plots. Transmission electron microscope images indicated the nanosized and spherical shape of the LPHNPs with fair size distribution. The nanoparticles ranged from 176 to 308nm, which increased with increased polymer concentration. The increase in polymer and lipid concentration also increased the drug entrapment efficiency. The in vitro drug release was in range 70.34-91.95% and the release mechanism follow the Higuchi model (R2=0.9888) and Fickian diffusion (n<0.5). The in vitro cytotoxicity assay and confocal microscopy of the optimized formulation demonstrate the good safety and better internalization of the LPHNPs. The cell antiproliferation showed the spatial and controlled action of the nanoformulation as compared to the plain drug solution. The results suggest that LPHNPs can be a promising delivery system envisioned to safe, stable and potentially controlled delivery of methotrexate to the cancer cells to achieve better therapeutic outcomes.

Abstract
Solid lipid nanoparticle (SLN), nanostructured lipid carriers (NLC) and hybrid nanoparticles, have gained increasing interest as drug delivery systems because of their potential to load and release drugs from the Biopharmaceutical classification system (BCS) of class II (low solubility and high permeability) and of class IV (low solubility and low permeability). Lipid properties (e.g. high solubilizing potential, biocompatibility, biotolerability, biodegradability and distinct route of absorption) contribute for the improvement of the bioavailability of these drugs for a set of administration routes. Their interest continues to grow, as translated by the number of patents being field worldwide. This paper discusses the recent advances on the use of SLN, NLC and lipid-polymer hybrid nanoparticles for the loading of lipophilic, poorly water-soluble and poorly permeable drugs, being developed for oral, topical, parenteral and ocular administration, also discussing the industrial applications of these systems. A review of the patents filled between 2014 and 2017, concerning the original inventions of lipid nanocarriers, is also provided.
