[PMID: 37998984 PMCID: PMC10670648 DOI: 10.3390/gels9110894] [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: 09/25/2023] [Revised: 11/06/2023] [Accepted: 11/10/2023] [Indexed: 11/25/2023] Open
Abstract
Dermatophytosis, the most prevalent fungal infection, is witnessing a rising incidence annually. To address this challenge, we developed a terbinafine-loaded oil-in-water nanoemulsion (TH-NE) through the aqueous microtitration method. The formulation comprised olive oil (oil phase), Span 80 (surfactant), and propylene glycol (co-surfactant). Pseudo-phase ternary diagrams and thermodynamic studies underscored the stability of TH-NE. Employing the Box-Behnken design (BBD), we optimized TH-NE, which resulted in a remarkable particle size of 28.07 nm ± 0.5, a low polydispersity index (PDI) of 0.1922 ± 0.1, and a substantial negative zeta potential of -41.87 mV ± 1. Subsequently, TH-NE was integrated into a 1.5% carbopol matrix, yielding a nanoemulgel (TH-NEG). Texture analysis of TH-NEG demonstrated a firmness of 168.00 g, a consistency of 229.81 g/s, negative cohesiveness (-83.36 g), and a work of cohesion at -107.02 g/s. In vitro drug release studies revealed an initial burst effect followed by sustained release, with TH-NEG achieving an impressive 88% release over 48 h, outperforming TH-NE (74%) and the marketed formulation (66%). Ex vivo release studies mirrored these results, with TH-NEG (86%) and TH-NE (71%) showcasing sustained drug release in comparison to the marketed formulation (67%). Confocal microscopy illustrated that TH-NEG and TH-NE penetrated to depths of 30 µm and 25 µm, respectively, into the epidermal layer. Furthermore, dermatokinetic studies highlighted the enhanced drug penetration of TH-NEG compared to TH-NE through mouse skin. In summary, our study establishes TH-NEG as a promising carrier for terbinafine in treating dermatophytosis, offering improved drug delivery and sustained release potential.

Abstract
Fungal skin diseases are recognized as a global burden disease that affect human quality adjusted life. Terbinafine belongs to allylamine and broad-spectrum antifungal drugs but considered practically insoluble. Different lipids/surfactant with two different molar ratios were investigated with Span 40-based niosomes; characterized for size, morphology, loading capacity (EE%), in vitro release, kinetics, and antifungal activities. Vesicle sizes (0.19-1.23 µm), EE% (25-99%), zeta potential (> -32 mV), and in vitro release rates were dependent on both lipid types and ratios. Higher ratios of Poloxamer 407 preferably formed mixed micelles rather than forming noisome bilayers. Both Compritol and Precirol were deemed to be potential alternatives to cholesterol as bilayer membrane stabilizers. Terbinafine-loaded Compritol and Precirol stabilized niosomes were successfully prepared and demonstrated superior antifungal activities in vitro (inhibition zones) using Candida albicans ATCC 60913.

Abstract
This study investigated pH-responsive Terbinafine HCL (TBH)-loaded nanogels as a new approach to treating superficial fungal infections. Acrylic acid (AA) is a synthetic monomer that was crosslinked with a natural polymer (gelatin) using a free radical polymerization technique to fabricate gelatin-g-poly-(acrylic acid) nanogels. Ammonium persulphate (APS) and N, N'-methylene bisacrylamide (MBA) were used as the initiator and crosslinker, respectively. Developed gelatin-g-poly-(acrylic acid) nanogels were evaluated for the swelling study (pH 1.2, 5, 7.4), DEE, particle size, FTIR, thermal stability (TGA, DSC), XRD, SEM, DEE, and in vitro drug release study to obtain optimized nanogels. Optimized nanogels were incorporated into 1% HPMC gel and then evaluated in comparison with Lamisil cream 1% for TBH stratum corneum retention, skin irritation, and in vitro and in vivo antifungal activity studies. Optimized nanogels (AAG 7) demonstrated a 255 nm particle size, 82.37% DEE, pH-dependent swelling, 92.15% of drug release (pH) 7.4 within 12 h, and a larger zone of inhibition compared to Lamisil cream. HPMC-loaded nanogels significantly improved the TBH skin retention percentage, as revealed by an ex vivo skin retention study, indicating the usefulness of nanogels for topical use. In vivo studies conducted on animal models infected with a fungal infection have further confirmed the effectiveness of nanogels compared with the Lamisil cream. Hence, Gelatin-g-poly-(acrylic acid) nanogels carrying poorly soluble TBH can be a promising approach for treating superficial fungal infections.

Dose Response 2022; 20:15593258221095977. [PMID: 35558872 PMCID: PMC9087256 DOI: 10.1177/15593258221095977] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Revised: 03/22/2022] [Accepted: 04/01/2022] [Indexed: 11/29/2022] Open
Abstract
Research aimed to develop and evaluate biodegradable, pH-responsive chemically
cross-linked Pluronic F127 co-poly- (acrylic acid) nanogels for dermal delivery
of Terbinafine HCL (TBH) to increase its permeability and as a new approach to
treat skin fungal infections. TBH-loaded nanogels were successfully synthesized
from acrylic acid (AA) and Pluronic F127 by free-radical copolymerization
technique using N,N′-methylene bisacrylamide (MBA) as crosslinker and ammonium
persulphate (APS) as initiator. Prepared nanogels exhibited 93.51% drug
entrapment efficiency (DEE), 45 nm particle size, pH-dependent swelling and
release behavior. Nanogels were characterized using different physicochemical
techniques. The ex-vivo skin retention studies through rat skin
showed about 42.34% drug retention from nanogels while 1% Lamisil cream
(marketed product) showed about 26.56% drug retention. Moreover, skin irritation
studies showed that nanogels were not irritating. Nanogels showed improved
in-vitro antifungal activity against Candida
albicans compared to commercial product. In-vivo
studies on rats infected with Candida albicans confirmed
superiority of nanogels over 1% Lamisil for eradication of fungal infection.
This confirms that TBH loaded in Pluronic F127 co-poly-(acrylic acid) nanogels
provided greater targetibility and cure rates of poorly soluble TBH in animal
model and hence nanogels could be a potential carrier for effective topical
delivery of TBH for skin fungal infection treatment.

Abstract
Skin permeation is an integral part of penetration of topical therapeutics. Zero order in addition to Higuchi permeation kinetic is usually preferred in topical drug delivery cargo. Penetration of therapeutic entities through epidermal barrier is a major challenge for scientific fraternity. Furthermore, penetration of therapeutic entities determines the transportation and ultimately therapeutic efficacy of topical dermal dosage forms. Apart from experimentation models, mathematical equations, in silico docking, molecular dynamics (MDs), and artificial neural network (Neural) techniques are being used to assess free energies and prediction of electrostatic attractions in order to predict the permeation phenomena of therapeutic entities. Therefore, in the present review, we have summarized the significance of kinetic equations, in silico docking, MDs, and ANN in assessing and predicting the penetration behavior of topical therapeutics through dermal dosage form. In addition, the role of chitosan biomacromolecule in modulating permeation of topical therapeutics in skin has also been illustrated using computational techniques.
