[PMID: 38518948 DOI: 10.1016/j.ijbiomac.2024.131034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2023] [Revised: 03/09/2024] [Accepted: 03/19/2024] [Indexed: 03/24/2024]
Abstract
This article has focused on collagen-gelatin, the gelation process, as well as blend interaction between collagen/gelatin with various polysaccharides to boost mucoadhesion and gastric retention. The interaction between mucoadhesive materials and mucin layers is of significant interest in the development of drug delivery systems and biomedical applications for effective targeting and prolonged time in the gastrointestinal tract. This paper reviews the current advancement and mucoadhesive properties of collagen/gelatin and different polysaccharide complexes concerning the mucin layer and interactions are briefly highlighted. Collagen/gelatin and polysaccharide blends biocompatible and biodegradable, the complex biomolecules have shown encouraging mucoadhesive properties due to their cationic nature and ability to form hydrogen bonds with mucin glycoproteins. The mucoadhesion mechanism was attributed to the electrostatic interactions between the positively charged amino (NH2) groups of blend biopolymers and the negatively charged sialic acid residues present in mucin glycoprotein. At the end of this article, the encouraging prospect of collagen/polysaccharide complex and mucin glycoprotein is highlighted.

Semperivium Ruthenicum Koch Extract-Loaded Bio-Adhesive Formulation: A Novel Oral Antioxidant Delivery System for Oxidative Stress Reduction. Pharmaceuticals (Basel) 2023; 16:1110.

Abstract
Periodontitis is a chronic inflammatory disease that affects the oral cavity and can ultimately lead to tooth loss. Oxidative stress has been identified as a key factor in the development of periodontitis. In recent years, natural polyphenols have gained attention for their anti-inflammatory and antioxidant effects. This study aims to evaluate the potential of a bio-adhesive patch loaded with Semperivium ruthenicum Koch extract, rich in polyphenols, as a novel oral antioxidant delivery system for reducing oxidative stress in periodontitis. The plant extracts were prepared by maceration and were subjected to HPLC analysis for the identification and quantification of polyphenols. The bio-adhesive patches were prepared using a solvent-casting technique and characterized for their technical characteristics and release kinetics. The patches demonstrated satisfactory technical characteristics and followed Korsmeyer-Peppas release kinetics, with the active ingredients diffusing non-Fickian from the polymer matrix as it eroded over time. The bio-adhesive strength of the patches was comparable to other similar formulations, suggesting that the obtained patches can be tested in vivo conditions. The results suggest that treating oral periodontitis with natural polyphenols may effectively scavenge free radicals and regulate cytokine activity, leading to a reduction in oxidative stress. The non-smoking group had a mean saliva antioxidant activity of 7.86 ± 0.66% while the smoking group had a mean value of 4.53 ± 0.15%. Furthermore, treating oral oxidative stress may also contribute to overall gut health, as studies have shown a correlation between oral and gut microbiomes. Therefore, the use of bio-adhesive patches containing polyphenols may provide a promising approach for the treatment of periodontitis and its associated complications.

Abstract
Terbinafine (TER) is a promising candidate medication for the topical treatment of fungal infections. However, its solubility in water and skin permeability are limited. To overcome these limitations, a Terbinafine niosome and niosomal gel was developed. The impact of cholesterol:surfactants on terbinafine incorporated niosome (terbinasome) preparations was examined. Differential scanning calorimetry (DSC), photon correlation spectroscopy (PCS), scanning electron microscopy (SEM), and attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy were used to assess the morphological features of terbinasome and the physicochemical characteristics of TER in terbinasome. The obtained results has shown that Chol enhanced the diameter of the terbinasome from 123.20 ± 2.86 to 701.93 ± 17.72 nm. The highest encapsulation of terbinafine was estimated to be around 66% due to the cholesterol:surfactants ratio in the terbinasome was 1:3 and 1:6. Additional examination has revealed that changes in the cholesterol:surfactants ratio can result in a change in the PDI value of between 0.421 ± 0.004 and 0.712 ± 0.011. The terbinasome gel was prepared and tested for pharmaceutical testing, including pH, viscosity, spreadability, and stability. The percentage of TER dissolution from terbinasome were determined more than 80% and showed quickest drug release. In a cutaneous permeability examination, the quantity of TER in the cutaneous layers and the receiver compartment were higher for the terbinasome gel than for the TER simple gel. The terbinasome's cell viability was around 90% (HFF cell line) and MTT experiment demonstrated that the terbinasome was not cytotoxic. The MIC of the terbinasome was lower than pure drug against Aspergillus, Fusarium, and Trichophyton. The terbinasomal gels were non-irritant (score < 2) in the cutaneous irritation examination performed on Wistar rats. The research suggests that the optimized terbinasome may be used as a nano-vesicle for TER drug administration, hence opening up new possibilities for the treatment of cutaneous infections.

Formulation and Development of Bioadhesive Oral Films Containing Usnea barbata (L.) F.H.Wigg Dry Ethanol Extract (F-UBE-HPC) with Antimicrobial and Anticancer Properties for Potential Use in Oral Cancer Complementary Therapy. Pharmaceutics 2022; 14:pharmaceutics14091808. [PMID: 36145557 PMCID: PMC9505056 DOI: 10.3390/pharmaceutics14091808] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Revised: 08/19/2022] [Accepted: 08/25/2022] [Indexed: 02/06/2023] Open
Abstract
Medical research explores plant extracts’ properties to obtain potential anticancer drugs. The present study aims to formulate, develop, and characterize the bioadhesive oral films containing Usnea barbata (L.) dry ethanol extract (F-UBE-HPC) and to investigate their anticancer potential for possible use in oral cancer therapy. The physicochemical and morphological properties of the bioadhesive oral films were analyzed through Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), Atomic Force Microscopy (AFM), thermogravimetric analysis (TG), and X-ray diffraction techniques. Pharmacotechnical evaluation (consisting of the measurement of the specific parameters: weight uniformity, thickness, folding endurance, tensile strength, elongation, moisture content, pH, disintegration time, swelling rate, and ex vivo mucoadhesion time) completed the bioadhesive films’ analysis. Next, oxidative stress, caspase 3/7 activity, nuclear condensation, lysosomal activity, and DNA synthesis induced by F-UBE-HPC in normal blood cell cultures and oral epithelial squamous cell carcinoma (CLS-354) cell line and its influence on both cell types’ division and proliferation was evaluated. The results reveal that each F-UBE-HPC contains 0.330 mg dry extract with a usnic acid (UA) content of 0.036 mg. The bioadhesive oral films are thin (0.093 ± 0.002 mm), reveal a neutral pH (7.10 ± 0.02), a disintegration time of 118 ± 3.16 s, an ex vivo bioadhesion time of 98 ± 3.58 min, and show a swelling ratio after 6 h of 289 ± 5.82%, being suitable for application on the oral mucosa. They displayed in vitro anticancer activity on CLS-354 tumor cells. By considerably increasing cellular oxidative stress and caspase 3/7 activity, they triggered apoptotic processes in oral cancer cells, inducing high levels of nuclear condensation and lysosomal activity, cell cycle arrest in G0/G1, and blocking DNA synthesis. All these properties lead to considering the UBE-loaded bioadhesive oral films suitable for potential application as a complementary therapy in oral cancer.

Abstract
Statement of the Problem Molar teeth with furcation involvement are one of the most common problems in patients with periodontal disease. Regeneration methods are of the most controversial treatment strategies for these lesions. Purpose The purpose of this study was to determine the effect of plasma rich in growth factors (PRGF) with 1.2% Atorvastatin (ATV) in the treatment of furcation involvement of mandibular molars. Materials and Method The present randomized clinical trial was conducted on 15 patients with moderate periodontitis and class II furcation involvements; 24 defects were located in four groups of six, including debridement, ATV1.2%, PRGF, PRGF with ATV1.2%. The parameters of vertical probing depth (VPD), vertical clinical attachment level (VCAL), gingival index (GI), horizontal probing depth (HPD) and gingival recession (GR) were measured at baseline (T0), immediately before surgery (T1), 3 (T2), and 6 (T3) months after surgery. Moreover, the bone conditions were evaluated by digital subtraction radiography before and six months after surgery. Data were analyzed using SPSS23 software. Results No significant difference in radiographic parameters was observed among the groups (p= 0.08). There was no significant difference in the mean levels of VPD, VCAL and HPD among the groups at different times (p<0.05). Comparison of clinical parameters of VPD, VCAL and GI in the treatment groups compared to the baseline showed a significant improvement in each group (p< 0.05) but there was no significant difference among different groups (p< 0.05). Conclusion The use of PRGF with ATV 1.2% in grade II furcation involvement in mandi-bular molars was effective in the improvement of clinical and radiographic parameters six months after treatment, but this effect revealed no difference in comparison with the other groups.

Abstract
Bioadhesive polymers offer versatility to medical and pharmaceutical inventions. The incorporation of such materials to conventional dosage forms or medical devices may confer or improve the adhesivity of the bioadhesive systems, subsequently prolonging their residence time at the site of absorption or action and providing sustained release of actives with improved bioavailability and therapeutic outcomes. For decades, much focus has been put on scientific works to replace synthetic polymers with biopolymers with desirable functional properties. Gelatine has been considered one of the most promising biopolymers. Despite its biodegradability, biocompatibility and unique biological properties, gelatine exhibits poor mechanical and adhesive properties, limiting its end-use applications. The chemical modification and blending of gelatine with other biomaterials are strategies proposed to improve its bioadhesivity. Here we discuss the classical approaches involving a variety of polymer blends and composite systems containing gelatine, and gelatine modifications via thiolation, methacrylation, catechol conjugation, amination and other newly devised strategies. We highlight several of the latest studies on these strategies and their relevant findings.

Abstract
Recurrent aphthous stomatitis (RAS) is a disease marked by painful oral lesions on the buccal and labial mucosa or tongue. Drug delivery systems (DDS) for RAS include topical forms that manage wound healing, cover the ulcer, and relieve the associated pain. DDS targeting the oral mucosa face a major challenge, especially the short residence times in the mouth due to the effect of “saliva wash-out”, which continually removes the drug. The objective of this review is to study the development of preparation forms and delivery systems of various types and preparations that have been used for RAS management from 1965 until February 2020. There are 20 types of DDS for RAS which were discussed in 62 articles. The preparations were classified into 4 preparation forms: liquid, semi-solid, solid, and miscellaneous. In addition, the ultimate DDS for RAS preparations is the semi-solid forms (41.94%), which include 5 types of DDS are gel, paste, patch, cream, and ointment. This preparation was developed into new preparation form (11.29%), such as adhesive alginates, dentifrice, OraDisc, membranes, bioresorbable plates, pellicles, and gelosomes. Generally, the mucosal drug delivery system is the method of choice in RAS treatment because the ulcer is commonly located in the oral mucosa. In conclusion, these preparations are designed to improve drug delivery and drug activity for the treatment of RAS ulcers. Moreover, almost all of these DDS are topical preparations that use various types of mucoadhesive polymers to increase both residence time in the oral mucosa and pain relief in RAS treatment.

Abstract
Diabetes mellitus (DM) is a chronic, progressive, and multifaceted illness resulting in significant physical and psychological detriment to patients. As of 2019, 463 million people are estimated to be living with DM worldwide, out of which 90% have type-2 diabetes mellitus (T2DM). Over the years, significant progress has been made in identifying the risk factors for developing T2DM, understanding its pathophysiology and uncovering various metabolic pathways implicated in the disease process. This has culminated in the implementation of robust prevention programmes and the development of effective pharmacological agents, which have had a favourable impact on the management of T2DM in recent times. Despite these advances, the incidence and prevalence of T2DM continue to rise. Continuing research in improving efficacy, potency, delivery and reducing the adverse effect profile of currently available formulations is required to keep pace with this growing health challenge. Moreover, new metabolic pathways need to be targeted to produce novel pharmacotherapy to restore glucose homeostasis and address metabolic sequelae in patients with T2DM. We searched PubMed, MEDLINE, and Google Scholar databases for recently included agents and novel medication under development for treatment of T2DM. We discuss the pathophysiology of T2DM and review how the emerging anti-diabetic agents target the metabolic pathways involved. We also look at some of the limiting factors to developing new medication and the introduction of unique methods, including facilitating drug delivery to bypass some of these obstacles. However, despite the advances in the therapeutic options for the treatment of T2DM in recent years, the industry still lacks a curative agent.

Abstract
Mucoadhesive buccal patch is a promising dosage form for a successful oral drug delivery, which provides unique advantages for various applications such as treatment of periodontal disease and postdental surgery disorders. The aim of this study is to synthesize a novel multifunctional mucoadhesive buccal patch in a multilayer reservoir design for therapeutic applications. The patches were fabricated through simultaneous electrospinning of chitosan/poly(vinylalcohol) (PVA)/ibuprofen and electrospraying of phenylalanine amino acid nanotubes (PhNTs) containing metronidazole into the electrospun mats through a layer-by-layer process. An electrospun poly(caprolactone) (PCL) was used as an impermeable backing layer to protect the mucoadhesive component from tongue movement and drug loss. Buccal patches were characterized using scanning electron microscopy (SEM) and field emission scanning electron microscopy (FESEM) and also evaluated in terms of physicomechanical parameters such as pH, weight, thickness, tensile strength, folding endurance, and mucoadhesive properties. The swelling index of the patches was examined with respect to the PVA/chitosan ratio. The effect of genipin addition to the electrospinning solution was also studied on mucoadhesive and swelling properties. The cell viability of buccal patches was assessed by methylthiazolydiphenyl-tetrazolium bromide test on L929 fibroblast cell line. The patch with an optimal amount of mucoadhesive polymers (PVA/chitosan 80:20) and crosslinking agent (0.05 g) indicated an ideal hemostatic activity along with antibacterial properties against Streptococcus mutans bacteria. The synthesized multifunctional mucoadhesive patch with a novel composition and design has a great potential for oral therapeutic applications.

Abstract
Herbal therapies are used worldwide to treat a variety of health conditions, including dental conditions in veterinary medicine. In this context, the use of medicinal plant-based formulations as potential therapeutics and preventatives in veterinary dentistry is worth highlighting. The objective of the present study was to develop a mucoadhesive ointment formulation, named orabase, that contained pomegranate extract for use in the oral cavity of dogs, with the aim of improving their oral hygiene. The hydroalcoholic extracts of pomegranate peels was incorporated into the orabase in 3 different concentrations. The formulations were subjected to in vitro microbiological testing by a modified disc-diffusion method to study the susceptibility of microorganisms collected from the oral cavities of the dogs. The samples were taken from the buccal mucosa of dogs having the same management and diet. The most effective formulation was submitted to physicochemical tests to evaluate the functionality of the product, namely pH, swelling index, spreadability, and mechanical properties (hardness, cohesiveness, and adhesiveness). The formulation containing 25.0% w/w of the extract was considered most suitable for the intended use as it showed antiseptic activity and demonstrated a swelling index of approximately 35% in the first 20 minutes of the test, high spreadability, and suitable mechanical properties. The results suggest that the product obtained from pomegranate peel extract is a viable option for use to improve oral hygiene, helping to reduce the bacterial component of dental plaque in dogs.

Abstract
Aim: The purpose of this study was to design a metformin nanoparticles (NPs)-loaded buccoadhesive film for enhanced drug bioavailability. Materials & methods: The NPs were prepared and incorporated into a hydroxypropyl methylcellulose-chitosan blend film. Three levels of a three-factor, Box-Behnken design were used to evaluate the critical formulation variables. The drug permeation was also examined using sheep buccal mucosa. Results & conclusion: The results verified the formation of spherical NPs with an average size of 177.8 ± 6.42 nm and entrapment efficiency of 78.03 ± 0.23%. The optimum conditions for nanofilms were predicted to be: hydroxypropyl methylcellulose (700 mg), glycerol (50 mg) and chitosan (0.15 %w/v). The nanofilm showed a high drug permeation within 6 h. The metformin nanofilm offers an excellent opportunity for buccal drug delivery.

Curr Drug Deliv 2020; 17:3-14. [DOI: 10.2174/1567201816666191106102020] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2019] [Revised: 09/14/2019] [Accepted: 10/15/2019] [Indexed: 12/26/2022]
Abstract
Background:
Diabetes is one of the most common chronic metabolic disorders which affect
the quality of human life worldwide. As per the WHO report, between 1980 to 2014, the number of
diabetes patients increases from 108 million to 422 million, with a global prevalence rate of 8.5% per
year. Diabetes is the prime reason behind various other diseases like kidney failure, stroke, heart disorders,
glaucoma, etc. It is recognized as the seventh leading cause of death throughout the world. The
available therapies are painful (insulin injections) and inconvenient due to higher dosing frequency.
Thus, to find out a promising and convenient treatment, extensive investigations are carried out globally
by combining novel carrier system (like microparticle, microneedle, nanocarrier, microbeads etc.) and
delivery devices (insulin pump, stimuli-responsive device, inhalation system, bioadhesive patch, insulin
pen etc.) for more precise diagnosis and painless or less invasive treatment of disease.
Objective:
The review article is made with an objective to compile information about various upcoming
and existing modern technologies developed to provide greater patient compliance and reduce the undesirable
side effect of the drug. These devices evade the necessity of daily insulin injection and offer a
rapid onset of action, which sustained for a prolonged duration of time to achieve a better therapeutic
effect.
Conclusion:
Despite numerous advantages, various commercialized approaches, like Afrezza (inhalation
insulin) have been a failure in recent years. Such results call for more potential work to develop a
promising system. The novel approaches range from the delivery of non-insulin blood glucose lowering
agents to insulin-based therapy with minimal invasion are highly desirable.

Abstract
Innovations in pharmaceutical research are striving for designing newer drug therapies to eradicate deadly diseases. Strategies for such inventions always flourish with keys and objectives of minimal adverse effects and effective treatment. Recent trends in pharmaceutical technology specify that mucoadhesive drug delivery system is particularly appropriate than oral control release, for getting local systematic delivery of drugs in GIT for an extended interval of time at a predetermined rate. However, it is somehow expensive and unpleasant sensation for some patients, but still it is needful for getting short enzymatic activity, simple administration without pain and evasion of fast pass metabolism. Usually the vehicles employed in drug delivery of mucoadhesive system have a significant impact that draws further attention to potential benefits like improved bioavailability of therapeutic agents, extensive drug residence time at the site of administration and a comparatively faster drug uptake into the systemic circulation. The drug release from mucoadhesive multiparticulates is contingent on several types of factors comprising carrier need to produce the multiparticles and quantity of medication drug contained in them. Mucoadhesion is characterized by selected theories and mechanisms. Various strategies emergent in mucoadhesive multiparticulate drug delivery system (MMDDS) by in-vitro as well as ex-vivo description and characterization are also critically discussed. Apart from these, the primary focus during this review is to highlight current patents, clinical status, and regulatory policy for enhancement of mucoadhesive multi-particulate drug delivery system in the present scenario.
