Front Pharmacol 2023; 14:1272454. [PMID: 37841920 PMCID: PMC10576434 DOI: 10.3389/fphar.2023.1272454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Accepted: 09/19/2023] [Indexed: 10/17/2023] Open
Abstract
Background: Topical lidocaine microemulsion preparations with low toxicity, low irritation, strong transdermal capability and convenient administration are urgently needed. Methods: Box-Behnken design was performed for three preparation conditions of 5% lidocaine microemulsions: mass ratio of the mass ratio of surfactant/(oil phase + surfactant) (X1), the mass ratio of olive oil/(α-linolenic acid + linoleic acid) (X2) and the water content W% (X3). Then, five multi-objective genetic algorithms were used to optimize the three evaluation indices to optimize the effects of lidocaine microemulsion preparations. Finally, the ideal optimization scheme was experimentally verified. Results: Non-dominated Sorting Genetic Algorithm-II was used for 30 random searches. Among these, Scheme 2: X1 = 0.75, X2 = 0.35, X3 = 75%, which resulted in Y1 = 0.17 μg/(cm2·s) and Y2 = 0.74 mg/cm2; and the Scheme 19: X1 = 0.68, X2 = 1.42, X3 = 75% which resulted in Y1 = 0.14 μg/(cm2·s) and Y2 = 0.80 mg/cm2, provided the best matches for the objective function requirements. The maximum and average fitness of the method have reached stability after 3 generations of evolution. Experimental verification of the above two schemes showed that there were no statistically significant differences between the measured values of Y1 and Y2 and the predicted values obtained by optimization (p > 0.05) and are close to the target value. Conclusion: Two lidocaine microemulsion preparation protocols were proposed in this study. These preparations resulted in good transdermal performance or long anesthesia duration, respectively.

[PMID: 37504466 PMCID: PMC10379975 DOI: 10.3390/gels9070587] [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: 06/26/2023] [Revised: 07/19/2023] [Accepted: 07/20/2023] [Indexed: 07/29/2023] Open
Abstract
Curcumin (Cur) is a kind of polyphenol with a variety of topical pharmacological properties including antioxidant, analgesic and anti-inflammatory activities. However, its low water solubility and poor skin bioavailability limit its effectiveness. In the current study, we aimed to develop microemulsion-based keratin-chitosan gel for the improvement of the topical activity of Cur. The curcumin-loaded microemulsion (CME) was formulated and then loaded into the keratin-chitosan (KCS) gel to form the CME-KCS gel. The formulated CME-KCS gel was evaluated for its characterization, in vitro release, in vitro skin permeation and in vivo activity. The results showed that the developed CME-KCS gel had an orange-yellow and gel-like appearance. The particle size and zeta potential of the CME-KCS gel were 186.45 ± 0.75 nm and 9.42 ± 0.86 mV, respectively. The CME-KCS gel showed desirable viscoelasticity, spreadability, bioadhesion and controlled drug release, which was suitable for topical application. The in vitro skin permeation and retention study showed that the CME-KCS gel had better in vitro skin penetration than the Cur solution and achieved maximum skin drug retention (3.75 ± 0.24 μg/cm2). In vivo experimental results confirmed that the CME-KCS gel was more effective than curcumin-loaded microemulsion (Cur-ME) in analgesic and anti-inflammatory activities. In addition, the CME-KCS gel did not cause any erythema or edema based on a mice skin irritation test. These findings indicated that the developed CME-KCS gel could improve the skin penetration and retention of Cur and could become a promising formulation for topical delivery to treat local diseases.

Abstract
Nano- and microemulsions are colloidal systems that are widely used in various fields of biomedicine, including wound and burn healing, cosmetology, the development of antibacterial and antiviral drugs, oncology, etc. The stability of these systems is governed by the balance of molecular interactions between nanodomains. Microemulsions as a colloidal form play a special important role in stability. The microemulsion is the thermodynamically stable phase from oil, water, surfactant and co-surfactant which forms the surface of drops with very small surface energy. The last phenomena determines the shortage time of all fluid dispersions including nanoemulsions and emulgels. This review examines the theory and main methods of obtaining nano- and microemulsions, particularly focusing on the structure of microemulsions and methods for emulsion analysis. Additionally, we have analyzed the main preclinical and clinical studies in the field of wound healing and the use of emulsions in cancer therapy, emphasizing the prospects for further developments in this area.

Abstract
Marketed lidocaine dosage forms (such as ointment, gels, and injections) used to manage acute and chronic pain showed a short duration of action (<2 h). In this study, a lidocaine-loaded cubosomal gel was prepared to sustain the release of lidocaine to prolong the local anesthetic effect (high drug retention in the skin). Lidocaine-loaded cubosomal gels were prepared by melt emulsification and sonication using Pluronic F127 and DL-α-monoolein (at different levels). The cubosomal gels were characterized by morphology, size, zeta potential, entrapment efficacy, assay, viscosity, pH, and texture profiles. Ex vivo lidocaine permeation and retention studies were performed using Sprague–Dawley rat skin. Transmission electron microscopy images confirmed the bi-continuous liquid crystalline phase with a honeycomb cubosome structure. The cubosomal particle size (103–227 nm), viscosity (13,524–15,627cp), and entrapment efficacy (78.4–94.7%) increase with the level of monoolein. The ex-vivo permeation study showed a biphasic release pattern, with lidocaine cleared from ointment within 4 h (97.9% cumulative release), while cubosomal gels showed sustained release up to 24 h (53.33–98.86% cumulative release). A skin retention study demonstrated that cubosomes can increase (up to 28-fold) the lidocaine content in the skin (4.56 mg) compared to ointment (0.19 mg). A rabbit skin irritation study showed no sign of irritation after the application of cubosomal gel. In the radiant heat tail-flick study, the local anesthetic effect of lidocaine from the cubosomal gel was sustained for up to 16 h with 1.43-fold higher efficacy than marketed ointment. In conclusion, the study demonstrated the potential of cubosomal nanoparticle-laden gel to sustain the release of lidocaine for prolonging local anesthetic effects for pain management.

Abstract
Ocular drug delivery using contact lenses may be able to substitute for eye drop therapy. However, issues with hydrophobic drugs (like bimatoprost that is used to treat glaucoma) such as low drug uptake using a simple soaking method into preformed contact lenses and alteration in the swelling and transmittance of lenses restricts the application for drug delivery. This research uses graphene oxide (GO) to control the release of bimatoprost from contact lenses along with improvements in the drug uptake, and lens swelling and transmittance. GO was loaded into silicone hydrogel contact lenses by adding the GO at the same time as lenses were polymerized. These lenses were soaked in bimatoprost. Alternatively contact lenses, either with or without GO, were produced by adding bimatoprost during lens polymerization. GO improved contact lens swelling due to its water binding capacity and lens transmittance due to the molecular dispersion of bimatoprost on the surface of the GO which prevented the local precipitation of the drug. The bimatoprost uptake was not improved in the presence of GO. However, its in vitro release profile was improved. Adding bimatoprost and GO at the same time as lenses were polymerized (DL-GO-BMT) significantly decreased the loss of drug during extraction and sterilization in comparison to contact lenses (DL-BMT) without GO. As the amount of GO was increased, the DL-GO-BMT lenses showed a significant decrease in the burst and cumulative release of bimatoprost. Ocular irritation and histopathology reports demonstrated the safety of GO contact lens. The in vivo pharmacokinetic studies in the rabbit tear fluid showed significant improvement in mean residence time (MRT) and area under the curve (AUC) with DL-GO-0.2 μg-BMT-100 contact lens in comparison to eye drop solution. The study demonstrated that the addition of GO to contact lenses can control the release of bimatoprost as well as improved the lens swelling and transmittance. However, further optimization is needed to modulate the release of drug within the therapeutic level to manage glaucoma.

Abstract
Pain remains a global health challenge affecting approximately 1.5 billion people worldwide. Pain has been an implicit variable in the equation of human life for many centuries considering different types and the magnitude of pain. Therefore, developing an efficacious drug delivery system for pain management remains an open challenge for researchers in the field of medicine. Lack of therapeutic efficacy still persists, despite high throughput studies in the field of pain management. Research scientists have been exploiting different alternatives to curb the adverse side effects of pain medications or attempting a more substantial approach to minimize the prevalence of pain. Various drug delivery systems have been developed such as nanoparticles, microparticles to curb adverse side effects of pain medications or minimize the prevalence of pain. This literature review firstly provides a brief introduction of pain as a sensation and its pharmacological interventions. Second, it highlights the most recent studies in the pharmaceutical field for pain management and serves as a strong base for future developments. Herein, we have classified drug delivery systems based on their sizes such as nano, micro, and macro systems, and for each of the reviewed systems, design, formulation strategies, and drug release performance has been discussed.

Abstract
Triptolide (extract of herb Tripterygium wilfordii) is widely used in rheumatoid arthritis due to its potent immunosuppressant effect. The marketed oral (tablet dosage forms) and parenteral injections have short duration of action (half-life = 38 min) and not limited to multiorgan toxicity, which restrict the use of triptolide in clinical practice. In this study, a triptolide-loaded Pluronic® F68-reduced graphene oxide transdermal (non-invasive) hydrogel was developed to achieve sustained release of triptolide. Fourier transform infrared spectroscopy, X-ray diffraction, and Raman spectroscopy confirmed the synthesis of Pluronic® F68-reduced graphene oxide. Transmission electron microscopy showed flat wrinkled-nanosheets. The developed hydrogel showed desirable viscosity (11,261-11,365 cps), adhesiveness (0.25 mJ), hardness (6.5 g), and cohesiveness (1.85) for transdermal application. The ex vivo release study demonstrated the ability of the Pluronic® F68-reduced graphene oxide hydrogel to prolong release up to 14 h (63.64-96.78%), owing to the strong π-π interactions between the graphene oxide and the triptolide. The in vivo pharmacokinetic parameters in the rat model confirmed the improvement in the relative bioavailability (3.3-fold) with Pluronic® F68-reduced graphene oxide hydrogel in comparison to the control hydrogel without reduced graphene oxide. The anti-rheumatoid efficacy model suggest the potential application of Pluronic® F68-reduced graphene oxide hydrogel to treat knee rheumatoid arthritis (70-75% resolution) to substitute tablets and parenteral injections.

Abstract
Clozapine is widely used to treat schizophrenia as an atypical antipsychotic. Low solubility, poor dissolution rate, degradation in the gastrointestinal tract, high hepatic first-pass metabolism, and eventually less drug transfer in the brain are all issues with oral clozapine administration. On account of this poor pharmacokinetic parameters, the authors aimed to develop clozapine nanosuspension using (+)-alpha-tocopherol polyethylene glycol 1000 succinate (TPGS) and polyvinylpyrrolidone K-30 (PVP K-30) and deliver it through the intranasal route. The nanosuspension was prepared by the high-speed homogenization method with 32 full factorial design for optimization of the product. Quality Target Product Profile (QTPP) was enlisted before the product development. The amount of TPGS and speed of homogenizer were selected as independent variables whereas, particle size and drug permeation profile after 24 h (Y2, %) were selected as dependent variables. As per the results of optimization, amount of TPGS and speed of homogenizer were chosen as 0.1% and 7000 rpm, respectively. The particle size of the optimized nanosuspension of clozapine was found to be 281 nm. The conversion of clozapine crystals to an amorphous form was verified by characterization studies (XRD and DSC). The drug permeability study showed 96.15% and 41.12% clozapine release after 24 h from nanosuspension and conventional suspension, respectively. The study of nasal cilio-toxicity (histopathological studies) demonstrated the appropriateness of nanosuspension for intranasal purposes. The single-dose in vivo pharmacokinetic analysis in the rat model showed a substantial increase in the therapeutic concentration of clozapine in the brain tissue in the case of intranasal nanosuspension (dose = 0.05 mg drug/0.1 mL, Cmax = 8.62 ± 0.45 μg/g, tmax = 1 h) compared to conventional oral clozapine suspension (dose = 26.43 mg drug/0.158 mL, Cmax = 1.14 ± 0.12 μg/g, tmax = 1 h).Ultimately, in the case of an intranasal route, a 3.56-fold increase in brain drug concentration was observed with a 528-fold lower drug dose compared with oral administration. The results suggest that clozapine nanosuspension may be used for successful nose-to-brain delivery.

Abstract
Currently, periodontitis is treated by oral dosage forms (antibiotics) which shows systemic side effects and failed to reach the therapeutic concentration (above minimum inhibitory concentration, MIC) in the periodontal pocket. The present study aimed to overcome the above issues, by designing tailored doxycycline hyclate laden in situ gel by Poloxamer 407, chitosan, and polyethylene glycol 600. The in situ gel-forming system has attracted attention owing to its ability of sustained drug release above MIC, easy administration (syringeability), and high drug retention (localization) in the periodontal cavity. The Box-Behnken design (BBD) was used to tailor and optimize the concentration of Poloxamer 407 (X1 = 14.3%), chitosan (X2 = 0.58%), and polyethylene glycol 600 (X3 = 1.14%) to achieve sufficient syringeability (149 N), t90% (1105 min), and viscosity at non-physiological condition (512 cps) and physiological condition (5415 cps). The optimized in situ gel was clear and isotonic (RBCs test). The gelation temperature of the optimized in situ was 34 ± 1°C with sufficient mucoadhesive strength (26 ± 2 dyn/cm2), gel strength (29 ± 2 sec), and texture profile for periodontal application. The in vitro drug release studies showed sustain release from optimized in situ gel (24h) in comparison to marketed gel (7h). The antimicrobial activity (cup plate technique) of the in situ gel was equivalent to the marketed doxycycline gel, which suggests that the doxycycline hyclate retained its antimicrobial efficacy when formulated as in situ gelling system. In conclusion, BBD was effectively utilized to optimize in situ gel with minimum level of polymers to achieve the required characteristics of the in situ gel for sustaining drug delivery to treat periodontitis.

Abstract
The patients with chronic pain in osteoarthritis often have insufficient pain relief from non-opioids analgesics. Buprenorphine is a promising molecule for symptomatic relief of chronic pain. The marketed parenteral injections and sublingual tablets have short duration of action (half-life = 2.7 h), which is not suitable to manage chronic pain. The purpose of this research was to design buprenorphine-loaded Pluronic F127-reduced graphene oxide transdermal (noninvasive) hydrogel to achieve sustained release of buprenorphine to manage chronic pain in osteoarthritis. Pluronic F127 was used to stabilize the reduced graphene oxide in hydrogel system. The characterization studies including Fourier transform infrared spectroscopy, X-ray diffraction, and Raman spectroscopy confirmed the synthesis of Pluronic F127-reduced graphene oxide from graphite. The transmission electron microscopy image showed flat nanosheets of reduced graphene oxide (rGO). The developed hydrogel showed desirable pH, viscosity, adhesiveness, hardness, and cohesiveness for transdermal application. The ex vivo release study demonstrated the ability of the Pluronic F127-reduced graphene oxide (P-rGO) hydrogel to prolong release up to 14 days, owing to the strong π-π interactions between the graphene oxide (GO) and the buprenorphine. In cold ethanol tail flick model, the GO hydrogel showed sustained analgesic effect in comparison with hydrogel without rGO. Thus, this study demonstrated the potential of using Pluronic F127-reduced graphene oxide nanocarriers to prolong local analgesia for effective management for chronic pain.

Abstract
Propofol is an oily liquid widely used for rapid onset of anaesthesia via intravenous route, which shows major limitations of hypersensitivity, anaphylactic reactions and pain. The aim of the present work was to bypass the above issues by formulating tailored niosomal gel to deliver propofol via non-invasive transdermal route. The niosomes were prepared by film hydration method and sonication using cholesterol and Span 80. The Box Behnken design (BBD) was applied to optimize the size (93.5 nm) and the entrapment efficacy (81.5%) of the niosomes by selecting cholesterol at 139 mg, Span 80 at 0.525% and sonication time at 5.13 min. The scanning electron microscopy image showed spherical shape niosomes with smooth surface without aggregation. The ex vivo release data showed significant improvement in the propofol release (92.2% after 10 h) using niosomes in comparison to the control propofol gel (with 30% methanol) without niosomes (25.3% after 10 h). The in vivo pharmacokinetic parameters in the rat model confirmed the improvement in the relative bioavailability with optimized niosomal gel (relative bioavailability = 12.12) in comparison to the control propofol gel. In conclusion, the niosomal gel offered a potential alternative non-invasive route to deliver propofol for procedural sedation especially in pediatric population.

Abstract
Rosuvastatin is an efficient antihyperlipidemic agent; however, being a BCS class II molecule, it shows poor oral bioavailability of < 20%. The present study focused on the improvement of oral bioavailability of rosuvastatin using tailored niosomes. The niosomes were prepared by film hydration method and sonication using cholesterol and Span 40. The Box-Behnken design (BBD) was applied to optimize the size (98 nm) and the entrapment efficacy (77%) of the niosomes by selecting cholesterol at 122 mg, Span 40 at 0.52%, and hydration time at 29.88 min. The transmission electron microscopy image showed spherical shape niosomes with smooth surface without aggregation. The ex vivo intestinal permeability studies showed significant improvement in the rosuvastatin permeation (95.5% after 2 h) using niosomes in comparison to the rosuvastatin suspension (40.1% after 2 h). The in vivo pharmacokinetic parameters in the rat model confirmed the improvement in the oral bioavailability with optimized rosuvastatin loaded niosomes (relative bioavailability = 2.01) in comparison to the rosuvastatin suspension, due to high surface area of niosomes and its lymphatic uptake via transcellular route. In conclusion, the optimized rosuvastatin loaded niosomes offers a promising approach to improve the oral bioavailability of rosuvastatin.

Abstract
Lidocaine is widely used as a local anesthetic for alleviation of post-operative pain and for management of acute and chronic painful conditions. Although several approaches are currently used to prolong the duration of action, an effective strategy to achieve neural blockage for several hours remains to be identified. In this study, a lidocaine-loaded Pluronic® F68-reduced graphene oxide hydrogel was developed to achieve sustained release of lidocaine. Fourier transform infrared spectroscopy, X-ray diffraction, and Raman spectroscopy confirmed the synthesis of Pluronic® F68-reduced graphene oxide. Transmission electron microscopy showed wrinkled, flat nanosheets with micelles attached. The developed hydrogel showed desirable pH, viscosity, adhesiveness, hardness, and cohesiveness for topical application. The ex vivo release study demonstrated the ability of the Pluronic® F68-reduced graphene oxide hydrogel to prolong release up to 10 h, owing to the strong π-π interactions between the graphene oxide and the lidocaine. In comparison with a commercial lidocaine ointment, the developed graphene oxide hydrogel showed sustained anesthetic effect in the radiant heat tail flick test and sciatic nerve block model. Thus, this study demonstrates the potential of using Pluronic® F68-reduced graphene oxide nanocarriers to realize prolonged effects of local anesthesia for effective pain management.

Abstract
Bronchial asthma is a chronic disease which is currently treated using various inhalants. However, the medication adherence with the inhalants is poor due to complex procedure to use them along with frequent dosing. In this paper, we have developed tulobuterol loaded Pluronic® F127-reduced graphene oxide transdermal hydrogel to sustain the release of tulobuterol to manage asthma for days. The synthesis of Pluronic® F127-reduced graphene oxide was confirmed by Fourier transform infrared spectroscopy, X-ray diffraction, and Raman spectroscopy. The transmission electron microscope showed wrinkled flat nano sheets. The hydrogel showed sufficient mechanical properties for topical application and was safe in the skin irritation study (rabbit model). The ex vivo release data demonstrated the ability of reduced graphene oxide to sustain the release of tulobuterol for 72 h, due to strong π-π interaction between drug and graphene oxide. The pharmacokinetic profile in Sprague-Dawley rat model confirmed the potential of tulobuterol-Pluronic® F127-reduced graphene oxide hydrogel to sustain the release of tulobuterol for effective management of asthma.

Abstract
In clinical practice, lidocaine is used as local anesthetic for the management of post-operative pain. The commercial formulation including gels, injections and ointments showed short duration of action (1 to 2 h). In this paper, the efforts have being made to develop tailored lidocaine-microemulsion (o/w), which on penetration in the skin layer cause micro-depots formation due to destabilization of the microemulsion system. To identify the microemulsion region, pseudo ternary diagrams were constructed using Capmul MCM as oil, Pluronic F68 as tri-block surfactant, polyethylene glycol 200 as co-surfactant at 1:4 and 1:6 ratios (S:Co-S). The selected 5%w/v lidocaine loaded microemulsion [Ld-ME-2(1:4)] was stable in thermodynamic test and during shelf life period (3 months). In ex vivo permeability study, the lidocaine release from Ld-ME-2(1:4) microemulsion was sustained in comparison to the marketed lidocaine ointment. The skin irritation study confirmed the safety of lidocaine loaded microemulsion. Tail flick test showed improved and sustain local anaesthetic effect in comparison to the market ointment. The improved efficacy of microemulsion system, was due to high penetration in the skin layer due to local precipitation of lidocaine from microemulsion. The findings suggest that the tailored microemulsion could be a potential strategy to prolong the local anaesthesia.
