Abstract
A promising controlled drug delivery system has been developed based on polymeric buccoadhesive bilayered formulation that uses a drug-free backing layer and a polymeric hydrophilic gel buccoadhesive core layer containing nifedipine. The DSC thermogravimetric analysis confirms the drug's entrapment in the gel layer and reveals no evidence of a potential interaction. Various ratios of bioadhesive polymers, including HPMC K100, PVP K30, SCMC, and CP 934, were combined with EC as an impermeable backing layer to ensure unidirectional drug release towards the buccal mucosa. The polymeric compositions of hydrophilic gel-natured HPMC, SCMC, and CP formed a matrix layer by surrounding the core nifedipine during compression. Preformulation studies were performed for all of the ingredients in order to evaluate their physical and flow characteristics. Ex vivo buccoadhesive strength, surface pH, swelling index, in vitro and in vivo drug release, and ex vivo permeation investigations were performed to evaluate the produced gel-based system. Rapid temperature variations had no appreciable impact on the substance's physical properties, pharmacological content, or buccoadhesive strength during stability testing using actual human saliva. It was clear from a histological examination of the ex vivo mucosa that the developed system did not cause any irritation or inflammation at the site of administration. The formulation NT5 was the best one, with a correlation coefficient of 0.9966. The in vitro and in vivo drug release profiles were well correlated, and they mimic the in vitro drug release pattern via the biological membrane. Thus, the developed gel-based formulation was found to be novel, stable, and useful for the targeted delivery of nifedipine.

Abstract
Mucoadhesive drug delivery systems have been extensively studied to effectively reduce the limitations of conventional drug delivery systems. Zein and polyvinyl pyrrolidone (PVP) are appraised for mucoadhesive properties. This study focuses on developing a mechanically stable zein/PVP electrospun membrane for propranolol hydrochloride (PL) transport. Fourier transform infrared, Raman spectra, and swelling studies gave evidence for PVP crosslinking, whereas circular dichroism spectroscopy revealed crosslinking of zein owing to the conformational change from α-helix to β-sheet. A 10 h thermal treatment of zein/PVP imparted 3.92 ± 0.13 MPa tensile strength to the matrix. Thermally crosslinked electrospun zein/PVP matrix showed 22.1 ± 0.1 g mm work of adhesion in porcine buccal mucosa tissue. Qualitative and quantitative evaluation of cytotoxicity in RPMI 2650 has been carried out. The in vitro drug release profile of PL from thermally crosslinked zein/PVP best fitted with the Korsmeyer-Peppas model. Immunostaining of β-catenin adherens junctional protein confirmed the absence of paracellular transport through the junctional opening. Still, drug permeation was observed through the porcine buccal mucosa, attributed to the transcellular transport of PL owing to its lipophilicity. The ex vivo permeation of PL through porcine buccal mucosa was also evaluated.

Abstract
Thiolation of polymers is one of the most appropriate approaches to impart higher mechanical strength and mucoadhesion. Thiol modification of gum karaya and gum acacia was carried out by esterification with 80% thioglycolic acid. FTIR, DSC and XRD confirmed the completion of thiolation reaction. Anticancer potential of developed thiomer was studied on cervical cancer cell lines (HeLa) and more than 60% of human cervical cell lines (HeLa) were inhibited at concentration of 5 µg/100 µL. Immobilized thiol groups were found to be 0.8511 mmol/g as determined by Ellman’s method. Cytotoxicity studies on L929 fibroblast cell lines indicated thiomers were biocompatible. Bilayered tablets were prepared using Ivabradine hydrochloride as the model drug and synthesized thiolated gums as mucoadhesive polymer. Tablets prepared using thiolated polymers in combination showed more swelling, mucoadhesion and residence time as compared to unmodified gums. Thiol modification controlled the release of the drug for 24 h and enhanced permeation of the drug up to 3 fold through porcine buccal mucosa as compared to tablets with unmodified gums. Thiolated polymer showed increased mucoadhesion and permeation, anticancer potential, controlled release and thus can be utilized as a novel excipient in formulation development.

Abstract
The objective was to apply a simplex lattice design to determine the properties of polyvinyl alcohol-graft-lactic acid (PVA-g-LA) with different values for two independent variables: curing time (X1) and LA ratio (X2). Each independent variable was varied among three levels: -1, 0, and +1. Three coded levels were 120 min, 150 min, and 180 min for X1 and 2.5 g, 5 g, and 7.5 g for X2. Dependent variables of swelling behavior in various swelling media and thermal analysis parameters were monitored. The optimal formulation was selected based on the desirability value. The prediction was accurate, showing a low value of percent error. The morphology of the selected formulation with the highest desirability value showed a compact and dense film. Propranolol hydrochloride used as a model drug, was loaded into PVA-g-LA film. The propranolol hydrochloride content was 4.19 ± 1.05 mg/cm2. The cumulative release and permeation of drug were 61.94 ± 8.03% and 59.96 ± 6.61%, respectively. Thus, response surface methodology can be used as a tool to predict or optimize the process parameters for PVA-g-LA transdermal films in an accurate manner. PVA-g-LA could control the release and permeation of drug from the film layer.

Abstract
The objective of this study was to formulate extended-release mucoadhesive buccal tablets of propranolol hydrochloride in order to provide a prolonged absorption of propranolol hydrochloride from the buccal mucosa and to reduce presystemic metabolism and thus provide a better therapeutic effect. Besides, the aim was to perform comparative in vivo pharmacokinetic and hemodynamic studies of the developed extended-release (ER) propranolol hydrochloride 10 mg mucoadhesive buccal tablets and commercial immediate-release (IR) propranolol hydrochloride 10 mg tablets in spontaneously hypertensive rats. Formulation with 15% polyethylene oxide showed the highest degree of propranolol hydrochloride permeation, satisfactory mucoadhesiveness, and extended-release of propranolol hydrochloride, thus it was selected for further in vivo study. The pharmacokinetic study in rats showed the superiority of ER mucoadhesive buccal tablets over IR tablets in terms of propranolol hydrochloride absorption extent (AUC values: 70.32 ± 19.56 versus 31.69 ± 6.97 µg·h/mL), although lower maximum plasma propranolol hydrochloride concentration (Cmax) was achieved. However, no statistically significant difference was observed in Cmax between these treatments. The hemodynamic study showed that ER mucoadhesive buccal tablets provide a more pronounced decrease primarily in heart rate, but also in systolic and diastolic arterial pressure, as well as a longer heart rate reduction compared to IR tablets.

Abstract
The current research article focused on formulating an easily applied, water-based buccal film loaded with the antiepileptic drug, lamotrigine (LTG). The designed film can be comfortably administered by epileptic patients to ensure a controllable therapeutic efficacy against seizures. The solubility of LTG in water was significantly improved by micellar solubilization. Upon testing several surfactants, three of them (Synperonic PE/P84, Brij L23, and Brij 78) achieved maximum possible solubility for LTG and were characterized for their micellar size, cloud point, and % transmittance. Selected micellar systems were incorporated within a buccal film prepared using solvent casting method based on either gelatin or polyvinylpyrrolidone (3%w/v) with 1.5%w/v propylene glycol as a plasticizer. Different micellar films were characterized for their physicochemical characteristics, swelling index, folding endurance, drug content uniformity, and in vitro LTG release. From the tested formulations, one formulation; LTG-BF1 (in which Brij 78 was used for the micellar solubilization and gelatin as the matrix former), was selected as the optimum and extensively studied for mucoadhesion, ex vivo permeation studies by Franz diffusion cells and confocal laser scanning microscopy. Results showed superior enhanced permeation of micellar film. LTG-BF1 was evaluated for the in vivo performance using rats. Status epilepticus was induced in rats by injecting Pentylenetetrazol (PTZ) i.p. at an initial dose of 30 mg/kg, followed by 10 mg/kg every10 min till 60 min. A group of rats receiving the designed buccal formulation (20 mg/kg) was compared with a group receiving the same dose of the oral market product and the normal control and PTZ groups. Rats receiving LTG-BF1 recorded reduced seizure scores at all stages, longer latency time, and higher threshold PTZ dose compared to PTZ and market product groups. In addition, LTG-BF1 reduced brain concentrations of TNF-α and TGF-β with an elevation of EAAT2 and GABA brain contents compared to PTZ and market product groups and ameliorated neuronal damage. In conclusion, LTG-loaded buccal micellar film proved a superior antiepileptic effect in PTZ induced acute epileptic model.

Abstract
Recurrent aphthous ulcer (RAU) is a well-known painful, inflammatory disease with uncertain etiology for which local symptomatic therapy is only available. The aim of this study was to formulate and characterize muco-adhesive sponges containing a mixture of tenoxicam and miconazole nitrate to manage pain, inflammation and avoid candida infection that may accompany RAU due to poor oral hygiene. Two polymers at different concentrations were used to prepare sponges applying simple freeze-drying. Medicated chitosan (2%) sponges (mC2) showed acceptable physical appearance, surface pH (6.3 ± 0.042), porosity (25.7% ± 1.8), swelling index (5.7 ± 0.11), in-vivo and ex-vivo muco-adhesion time (115 min.±0.813 and 155 min.±1.537, respectively), ex-vivo muco-adhesion force (0.09 N ± 0.002) and scanning electron microscope (SEM) images. For concurrent clear-cut determination of tenoxicam and miconazole nitrate from mC2, a new UPLC method was developed and validated. mC2 sponges exhibited superior in-vitro drug release profiles where ∼100% of tenoxicam released within 5 min for fast pain relief with a more prolonged miconazole nitrate release. Furthermore, in-vivo animal study revealed that mC2 caused a significant decrease in the acetic acid-induced ulcer size in rats after 6 days of treatment (p < .0001) compared to negative and positive controls. Additionally, histopathological examination showed faster healing with complete restoration of the normal oral histology in rats. The present study concludes that chitosan sponge loaded with a combination of tenoxicam and miconazole nitrate could improve healing of RAU cases.

Abstract
This project was aimed to formulate and characterize mucoadhesive buccal tablets of aceclofenac, utilizing different proportions of three polymers carbopol 934, hydroxypropyl methylcellulose, and sodium carboxymethylcellulose. Twelve batches of buccoadhesive aceclofenac were prepared by the direct compression method. The compressed tablets were then evaluated for physicochemical parameters such as hardness, thickness, weight variation, drug content, friability, swelling index, surface pH, and ex vivo mucoadhesion. In vitro dissolution test was conducted for 12 h according to Indian Pharmacopeia 2018, using the rotating paddle method in phosphate buffer of pH 7.4. Physiochemical parameters like weight variation (231.25–268.75 mg), hardness (8.32–11.56 kg), friability (0.04–0.2%), diameter (9.00 mm), thickness (3.8–4.05 mm), and drug content ((97.67–102.25%) were within the acceptable limit as per Indian Pharmacopeia 2018. The swelling index was reported to be in the range of 112.93–450.19%, at 8 h. The surface pHs of all the batches were in between 6.72 to 6.96. The mucoadhesive strengths (40.5–50 g) varied with the change in polymer concentrations especially of carbopol 934. The dissolution profile of all the batches varied greatly, with a maximum release of 109.41% (in batch 12 at 6 h) to a minimum release of 44.82% (in batch 3 at 12 h). Among them, only batch 1 ensured sustained and effective drug release (88.34% at 12 h) with appropriate swelling index (112.93%) and mucoadhesive strength (40 g). Fourier Transform Infrared Spectroscopy analysis showed no evidence of drug excipients interaction. Hence, the results concluded that buccal mucoadhesive aceclofenac tablets can be formulated. Furthermore, the property of the tablet not only depends on the concentration but also the behavior of the polymers used.

Abstract
Buccal matrices represent a widely accepted dosage form permitting a convenient, easy, reliable drug administration and reducing administration errors. The aim of this study was the development of mucoadhesive buccal matrices for propranolol administration in children. Matrices were obtained by freeze-drying of drug loaded polymeric solutions based on gum tragacanth (GT), pectin (PEC), hydroxypropylmethylcellulose (HPMC), sodium hyaluronate (HA), gelatin (GEL), chitosan (CH) or a mixture of CH and HPMC (CH/HPMC). Matrices were characterized for drug solid state, morphology, water-uptake, mucoadhesion ability, in vitro drug release and permeation through porcine epithelium. The most promising formulations were tested for in vitro biocompatibility in human dental pulp fibroblasts. The preparative method and the polymeric composition influenced the drug solid state, as a complete amorphization as well as different polymorphic forms were observed. GEL and PEC guaranteed a fast and complete drug release due to their rapid dissolution, while for the other matrices the release was influenced by drug diffusion through the viscous gelled matrix. Moreover, matrices based on CH and CH/HPMC showed the best mucoadhesive properties, favoured the drug permeation, in virtue of CH ability to interfere with the lipid organization of biological membrane, and were characterized by a good biocompatibility profile.

Abstract
Objective To formulate and assess bucco-adhesive films of propranolol hydrochloride for pediatric use. Methods Different films were formulated adopting mucin, polyvinyl alcohol, chitosan and carbopol. A drug/polymer compatibility study was conducted adopting differential scanning calorimetry and Fourier transform infrared spectroscopy. The prepared films were physically investigated for variation of weight, propranolol content, thickness, surface pH, proportion of moisture, folding endurance and mucoadhesion. In vitro drug release study and kinetic analysis of the corresponding data have been conducted. The optimized formulation was selected for a bioavailability study using albino rabbits and adopting a developed HPLC method. The pharmacokinetic parameters of the drug were calculated following administration of the optimized film and the corresponding marketed oral tablets to albino rabbits. Key Finding The compatibility study revealed the absence of drug/polymer interaction. The film formulations had suitable mucoadhesive and mechanical properties. The optimized formulation exhibited reasonable drug release that followed Higuchi diffusion pattern. The calculated AUC0-8h presented an enhancement in the bioavailability of propranolol hydrochloride from the selected film formulation by 1.9 times relative to the marketed propranolol oral tablets. Conclusion These findings support that propranolol hydrochloride bucco-adhesive film can be considered as a proper effective dosage form for pediatric delivery.

Abstract
Aim: The aim of this work was to develop buccoadhesive tablets for the systemic delivery of duloxetine HCl (DXT) using more soluble derivatives of β-cyclodextrin, i.e. hydroxypropyl-β-cyclodextrin (HPβCD) and sulfobutylether-β-cyclodextrin (SBEβCD) and to investigate enhanced cellular uptake of inclusion complexed drug.Materials and methods: Freeze dried and spray dried complexes of both cyclodextrin derivatives with DXT (1:1 molar) were prepared and characterized with DSC, FTIR, and PXRD techniques. C971 and PC, on the basis of swelling behavior, erosion and in vitro residence time, were selected for further study at different levels (-1, 0, +1) to optimize the formulation in terms of enhanced drug release and ex vivo permeation.Results: SBEβCD based complexes show more aqueous solubility of DXT (0.782 and 0.958 mM) and more complexation efficiency compared to HPβCD at 25 °C and 37 °C, respectively. Apparent stability constant was reported to be higher (1109.94 and 1693.25 M-1) for DXT-SBEβCD at 25 °C and 37 °C, respectively, than the corresponding values for DXT-HPβCD systems. Enhanced cellular uptake using fibroblast cells was revealed for complexed drug compared to free drug .Conclusion: Both cyclodextrin derivatives are able to enhance drug release and permeation in vitro and ex vivo.

Abstract
Preterm labor is the main cause of death and serious illness of both infants and pregnant women in Africa and worldwide. Parenteral and oral salbutamol sulfate as a B2 antagonist has been used for the treatment of preterm labor. The study aims are to formulate salbutamol sulfate non-invasive vaginal bioadhesive tablets to avoid the side effects of conventional formulations. Full factorial design 41 ×31 ×21 was used for the preparation of 24 vaginal bioadhesive tablet formulations. The independent factors were polymer type (Carbopol 934, HPMC 4000, HEC, and PEG 6000), polymer to drug ratio (1:1, 2:1, and 3:1), and diluent (lactose and mannitol). Vaginal bioadhesive tablets were evaluated for residence time and time required for release 50% of salbutamol sulfate T50% as dependent variables. The formulations were evaluated in terms of drug content, mass variation, hardness, friability, swelling index, residence time, and in-vitro drug release. Results revealed that polymer and diluent types are the most significant factors in both residence time and T50%. A strong positive correlation (0.91) between in-vitro and ex-vivo permeation was observed, which predict the best in-vivo performance of salbutamol vaginal bioadhesive tablet. Thus, salbutamol sulfate vaginal bioadhesive tablets could be a successful remedy for preterm labor.

Abstract
The aim of this study was to formulate an easily-administered, safe and effective dosage form loaded with meclizine for treatment of chemotherapy-induced nausea and vomiting (CINV) through the buccal route. CINV comprises bothersome side effects accompanying cytotoxic drugs administration in cancer patients. Meclizine was loaded in chitosan-pectin nanoparticles which were further incorporated within a buccal film. Different formulations were prepared based on a 21.31 full factorial study using Design Expert®8. The optimum formulation possessed favorable characters regarding its particle size (129 nm), entrapment efficiency (90%) and release profile. Moreover, its permeation efficiency through sheep buccal mucosa was assessed via Franz cell diffusion and confocal laser microscopy methods. Enhanced permeation was achieved compared with the free drug form. In-vivo performance was assessed using cyclophosphamide induced emesis. The proposed formulation exerted significant relief of the measured responses (reduced body weight and motor coordination, elevated emesis, anorexia, proinflammatory mediators and neurotransmitters that were also associated with scattered degenerated neurons and glial cells). The developed formulation ameliorated all behavioral, biochemical and histopathological changes induced by cyclophosphamide. The obtained data were promising suggesting that our bioadhesive formulation can offer an auspicious medication for treating distressing symptoms associated with chemotherapy for cancer patients.

Abstract
The success of mucoadhesive drug delivery systems relies on the type of polymer used, which becomes adhesive naturally upon hydration. Intended polymers should be able to maintain prolonged contact with biological membranes, and to protect or cater the drug to a prolonged period. Most of the hydro polymers form weak non-covalent bonds, that hinder localization of dosage forms at specific sites resulting in therapeutic inefficiency. This can be overcome by the thiol functionalization of natural polymers. In the present study, natural okra gum (OG) was extracted, followed by thiolation (TOG) and evaluated for mucoadhesion property and its role in enhancing the efficacy of repaglinide as a model drug (short-acting Type II antidiabetic drug). The thiol functionalization of OG (TOG) was confirmed by a Fourier-transform infrared spectroscopy (FTIR) study that showed a polyhedral to a spherical shape that had a rougher surface. Differential scanning calorimetry (DSC) and X-Ray Diffraction (XRD) studies of TOG indicated a decline in endothermic transition temperature and high crystallinity, respectively, in comparison to OG. CSFR (Crushing Strength: Friability Ratio), weight and thickness variations of repaglinidetablets formulated using TOG were >80% and <2.5% respectively. The highest swelling index (107.89 ± 1.99%) and strong mucoadhesion due to high disulfide bonds were observed for repaglinide TOG tablets in comparison to RG OG tablets. In-vitro release studies indicated a controlled drug release from thiolated formulations proportional to the concentration of thiomers that have a good correlation with in-vivo studies. Pharmacokinetic studies indicated higher AUC (area under the curve), longer t1/2 with thiomers. and Level A IVIV (in vitro in vivo) correlation was established from the bioavailability and dissolution data. Consequently, all the obtained results suggest that thiomers based formulations can be promising drug delivery systems, even in targeting onerous mucosal surfaces like nasal, ocular or vaginal.

Abstract
Hypertension shows circadian blood pressure rhythms (day-night pattern) that urge the delivery of antihypertensive drugs at the right time in the desired levels. Thus, a bilayered core-in-cup buccoadhesive tablet was formulated that immediately releases olmesartan, to give a burst effect, and controls azelnidipine release, to prolong its therapeutic effect. The main challenge was the poor bioavailability of azelnidipine due to its poor aqueous solubility and first-pass effect. Hence, liquisolid compact buccoadhesive tablets were prepared to enhance solubility, dissolution profiles, and bypass the oral route. Two factorial designs were conducted to study the type and concentration effect of the mucoadhesive polymers on the dissolution and mucoadhesion of olmesartan and azelnidipine. Characterization studies were conducted regarding drug content, surface pH, water uptake, mucoadhesive strength, in vitro release, and ex vivo permeability. The core-in-cup olmesartan/azelnidipine buccoadhesive tablet showed similar release profile to the statistically optimized formulae of each drug. In vitro dissolution study showed enhanced release of azelnidipine than the directly compressed tablets, to comply with the regulatory standards of controlled release systems. In vivo pharmacokinetic study of olmesartan and azelnidipine conducted on human volunteers against Rezaltas® 10/8 mg tablet showed percentage relative bioavailability of 106.12 and 470.82%, respectively.

Abstract
BACKGROUND Fast Orally Dissolving Film preparation can be used for patients with problems in ingesting solid dosage forms, such as mentally ill, elderly, geriatric and patients who are reducing fluid intake or nausea. AIM This study aimed to formulate and evaluate the rapid dissolution of amlodipine besylate. METHODS Amlodipine besylate film was prepared by solvent casting method by using hydroxypropyl methylcellulose (HPMC) as film formers, crospovidone as superdisintegrant with Varian concentration F1 (2%), F2 (4%), F3 (6%) and F4 (8%), PEG 400 as plasticizer, sucralose and sorbitol as sweetener, citric acid as saliva stimulation, and grape essence as flavoring and coloring agent. Characteristics of films include organoleptic, weight uniformity, film thickness, surface pH, swelling, uniformity of content, time of disintegration, and dissolution. RESULTS All formulated films produced a good film, smooth, transparent and uniform physical properties. F2 with polymer HPMC and the 4% concentration of crospovidone was the best formula with 31.50 seconds of disintegration time, the index expanding at the 15 second by 242.29% and the cumulative percent of the drug at 80 seconds by 98.08%. CONCLUSION Amlodipine besylate can be formulated into fast orally dissolving film preparations using HPMC and crospovidone polymers so that they may be considered for use in the treatment of hypertension for patients with drug-induced problems in tablet or capsule form.

Abstract
The use of nanocarrier delivery systems for direct nose to brain drug delivery shows promise for achieving increased brain drug levels as compared to simple solution systems. An example of such nanocarriers is emulsomes formed from lipid cores surrounded and stabilised by a corona of phospholipids (PC) and a coating of Tween 80, which combines the properties of both liposomes and emulsions. Oxcarbazepine (OX), an antiepileptic drug, was entrapped in emulsomes and then localized in a poly(lactic acid-co-glycolic acid)-poly(ethylene glycol)-poly(lactic acid-co-glycolic acid) (PLGA-PEG-PLGA) triblock copolymer thermogel. The incorporation of OX emulsomes in thermogels retarded drug release and increased its residence time (MRT) in rats. The OX-emulsome and the OX-emulsome-thermogel formulations showed in vitro sustained drug release of 81.1 and 53.5%, respectively, over a period of 24 h. The pharmacokinetic studies in rats showed transport of OX to the systemic circulation after nasal administration with a higher uptake in the brain tissue in case of OX-emulsomes and highest MRT for OX-emulsomal-thermogels as compared to the IN OX-emulsomes, OX-solution and Trileptal® suspension. Histopathological examination of nasal tissues showed a mild vascular congestion and moderate inflammatory changes around congested vessels compared to saline control, but lower toxic effect than that reported in case of the drug solution.

Abstract
A two factor three level factorial design was used to investigate the effects of carbopol and cationic hydrophilic polymers which have a common use in buccal drug formulations. Statistical models with interaction terms were derived to evaluate influence of carbopol (X1) and chitosan (X2) on tablet disintegration (Y1) and dissolution (Y2), mechanical properties (Y3), swelling (Y4). Tablet disintegration studies were carried out using two different pH environments within buccal region pH limits and also two different commonly used dissolution methods for buccal tablets were also investigated to compare the effect of polymer type on dissolution. Polymer type and ratio affect the characteristics of the buccal tablets due to their different physicochemical behavior at buccal pH. Also significant variances between dissolution profiles for buccal tablets, using either USP Paddle or flow through cell methods were found. These results indicate that both polymer type and ratio as well as combination of them effects the drug behavior in different ways.

Abstract
Mucoadhesive buccal film is developed as a promising dosage form, which has prominent advantages because of drug delivery through buccal mucosa. New formulation of buccal films containing rizatriptan benzoate (RB) was prepared by solvent casting method using various concentrations of hydroxypropyl methylcellulose (HPMC K4M), polyvinyl alcohol (PVA), polyethylene oxide (PEO), glycerol, stevia, and goat buccal mucosa used as a model membrane. In this work, the effect of polymers and plasticizer concentrations on drug release profile, disintegration and dissolution time, mechanical properties, and mucoadhesive characteristics of films was studied. Scanning electron microscopy analysis revealed uniform distribution of RB in film formulations. Chemical compounds and thermal analysis of the films were studied by Fourier transform infrared spectroscopy and differential scanning calorimetry, respectively. The buccal films produced were uniform in drug content and thickness. All formulations have in vitro release of 98–102% between 40 and 80 min. Also ex vivo mucoadhesion strength was in the range of 0.205 ± 0.035 to 0.790 ± 0.014 N for all formulations. A formulation consisting RB (50 mg), HPMC K4M, PVA, and PEO (63 mg), glycerol (1.5 ml), stevia (5 mg) was selected as our optimum composition. More satisfactory results were obtained in terms of disintegration and dissolution time, mechanical properties, and mucoadhesive characteristics. In addition, it showed about 99.89% RB released in 45 min. The results suggest that RB-loaded mucoadhesive buccal films could be a potential candidate to achieve optimum drug release for effective treatment of migraine.

Abstract
A mucoadhesive drug delivery system can improve the effectiveness of a drug, allowing targeting and localization at a specific site. According to this assumption, γ-irradiation as eco-friendly technique was employed to synthesize (acrylic acid/polyethylene glycol) copolymer hydrogel of different compositions. Silver nanoparticles were prepared within (acrylic acid/polyethylene glycol) hydrogel network by means of in situ reduction of silver nitrate using sodium borohydride as a reducing agent. Swelling characteristics in distilled water and simulated saliva solution were studied as a function of copolymer composition and preparation irradiation dose. (Acrylic acid/polyethylene glycol) hydrogels and their developed Agº nanocomposites have been characterized using scanning electron microscope, thermogravimetric analysis, transmission electron microscopy, energy dispersive X-ray spectroscopy, and X-ray diffraction. Mucoadhesive strength as well as self-disinfection efficiency expressed as antibacterial activity against different bacterial strains was evaluated. Propranolol HCl as model drug was used to evaluate the potential efficiency of the obtained (acrylic acid/polyethylene glycol)-Agº nanocomposites as mucoadhesive drug carrier. The obtained results showed that the (acrylic acid/polyethylene glycol)-Agº nanocomposites show a promising self-disinfection property, and the propranolol HCl–loaded composites were able to deliver the loaded drug in a sustainable manner that lasts for about 600 min.

Abstract
OBJECTIVE Betahistine dihydrochloride (BH.2HCl), an anti-vertigo histamine analog used in the treatment of Ménière's disease, undergoes extensive first-pass metabolism and suffers from short biological half-life. The aim of the present work was to develop and estimate controlled release mucoadhesive buccal tablets of BH.2HCl with a unidirectional drug flow to overcome this encumbrance. METHODS A direct compression method was adopted for preparation of the tablets using mucoadhesive polymers like guar gum, hydroxypropyl methyl cellulose K4M, sodium carboxymethyl cellulose and their combinations. The tablets were coated from all surfaces except one surface with a solution of 5% (w/v) cellulose acetate and 1% (w/v) dibutyl phthalate. Different permeation enhancers like 2% sodium deoxycholate, 2% sodium cholate hydrate (SCH) and 5% menthol were tested. Swelling index, ex vivo residence time, mucoadhesion strength, in vivo testing of mucoadhesion time, in vitro dissolution and ex vivo permeation were carried out. Furthermore, compatibility and accelerated stability studies were performed for the drug excipients. Finally, drug bioavailability of the BH.2HCl-optimized buccal mucoadhesive formulation was compared with that of the orally administered Betaserc® 24 mg tablet in six healthy male volunteers. RESULTS Formulation F10, which contained a combination of 35% guar gum and 5% sodium carboxymethyl cellulose, exhibited long adhesion time, high adhesion strength and diminished irritation to volunteers and showed zero-order release kinetics. SCH produced a significant enhancement in permeation of BH.2HCl across buccal mucosa. BH.2HCl-optimized buccal mucoadhesive formulation showed percentage relative bioavailability of 177%. CONCLUSION The developed mucoadhesive tablets represent a promising alternative for the buccal delivery of BH.2HCl.

Abstract
This work aims to prepare sustained release buccal mucoadhesive lyophilized chitosan sponges of buspirone hydrochloride (BH) to improve its systemic bioavailability. Chitosan sponges were prepared using simple casting/freeze-drying technique according to 3(2) factorial design where chitosan grade was set at three levels (low, medium, and high molecular weight), and concentration of chitosan solution at three levels (0.5, 1, and 2%). Mucoadhesion force, ex vivo mucoadhesion time, percent BH released after 8 h (Q8h), and time for release of 50% BH (T50%) were chosen as dependent variables. Additional BH cup and core buccal chitosan sponge were prepared to achieve uni-directional BH release toward the buccal mucosa. Sponges were evaluated in terms of drug content, surface pH, scanning electron microscopy, swelling index, mucoadhesion strength, ex vivo mucoadhesion time, and in vitro drug release. Cup and core sponge (HCH 0.5E) were able to adhere to the buccal mucosa for 8 h. It showed Q8h of 68.89% and exhibited a uni-directional drug release profile following Higuchi diffusion model.

Abstract
The present research work focused on the comparative assessment of porous versus nonporous films in order to develop a suitable buccoadhesive device for the delivery of glibenclamide. Both films were prepared by solvent casting technique using the 3(2) full factorial design, developing nine formulations (F1-F9). The films were evaluated for ex vivo mucoadhesive force, ex vivo mucoadhesion time, in vitro drug release (using a modified flow-through drug release apparatus), and ex vivo drug permeation. The mucoadhesive force, mucoadhesion time, swelling index, and tensile strength were observed to be directly proportional to the content of HPMC K4M. The optimized porous film (F4) showed an in vitro drug release of 84.47 ± 0.98%, ex vivo mucoadhesive force of 0.24 ± 0.04 N, and ex vivo mucoadhesion time of 539.11 ± 3.05 min, while the nonporous film (NF4) with the same polymer composition showed a release of 62.66 ± 0.87%, mucoadhesive force of 0.20 ± 0.05 N, and mucoadhesive time of 510 ± 2.00 min. The porous film showed significant differences for drug release and mucoadhesion time (p < 0.05) versus the nonporous film. The mechanism of drug release was observed to follow non-Fickian diffusion (0.1 < n < 0.5) for both porous and nonporous films. Ex vivo permeation studies through chicken buccal mucosa indicated improved drug permeation in porous films versus nonporous films. The present investigation established porous films to be a cost-effective buccoadhesive delivery system of glibenclamide.

Abstract
Mucoadhesion can be defined as a state in which two components, of which one is of biological origin, are held together for extended periods of time by the help of interfacial forces. Among the various transmucosal routes, buccal mucosa has excellent accessibility and relatively immobile mucosa, hence suitable for administration of retentive dosage form. The objective of this paper is to review the works done so far in the field of mucoadhesive buccal drug delivery systems (MBDDS), with a clinical perspective. Starting with a brief introduction of the mucoadhesive drug delivery systems, oral mucosa, and the theories of mucoadhesion, this article then proceeds to cover the works done so far in the field of MBDDS, categorizing them on the basis of ailments they are meant to cure. Additionally, we focus on the various patents, recent advancements, and challenges as well as the future prospects for mucoadhesive buccal drug delivery systems.

Abstract
Background: A novel aspiration in treatment of migraine, to provide greater therapeutic effect, overcome the side effects by complex therapeutic regimen and to improve patient compliance upon administering bucco-adhesive tablet formulations of sumatriptan succinate which have not been tested literally. Materials and Methods: This study was designed to develop a bucco-adhesive tablet containing sumatriptan succinate using blends of different bio-adhesive polymeric combinations such as hydroxy propyl methyl cellulose K4M, sodium carboxy methyl cellulose, and Carbopol 934P with a backing layer of ethyl cellulose by a direct compression technique. Tablets were subjected to physico-chemical parameters, swelling index, surface pH, ex vivo bioadhesive force, in vitro drug release, ex vivo drug permeation, and stability in saliva. Results: Good results were obtained in all the evaluated parameters. The drug release of all formulation follows zero-order kinetics by a diffusion mechanism type. Stability studies in human saliva, ex vivo buccal permeation studies by using sheep and porcine buccal mucosa were carried out for the optimized formulation (S4 CP:HPMC 3:1). Conclusion: The developed buccal drug delivery system containing sumatriptan succinate might be the alternative routes available to bypass the first pass metabolism and might be a milestone in the therapy of migraine and among all formulations S4 shows good controlled release results correlated with ex vivo permeation studies.

Abstract
Background: Glibenclamide (G) is a popular anti-diabetic drug, belonging to the class of sulfonylurea. The drug is widely used for treating type II diabetes but it undergoes first-pass effect. A novel aspiration in treatment of diabetes, to provide greater therapeutic effect, bypass first pass effect and to improve patient compliance upon administering buccal drug delivery of Glibenclamide (G) have not been tested literally. Hence, the present study was designed to develop the buccal mucoadhesive films of glibenclamide by solvent casting technique; that is by using different polymers such as Hydroxy Propyl Methyl Cellulose 15 cps (HPMC), carbopol (CP), and poly vinyl pyrrolidone. Propylene glycol, which served the purpose of plasticizer as well as penetration enhancer and the backing membrane used was aluminium foil. Materials and Methods: The films were subjected to physicochemical parameters, in-vitro drug release and ex vivo bucco adhesive strength. Results: The satisfactory results were obtained in all prepared formulation and based on the results G14 [HPMC (150 mg) + CP(20 mg) + PVP (30 mg)] was the best one compared to others. The drug release of all formulation follows zero order kinetics by diffusion mechanism of non-fickian diffusion type. Ex vivo, buccal permeation studies by using sheep buccal mucosa and finally stability studies by using human saliva were carried out for the optimized formulation G14.Good correlation was observed between in-vitro and in vivo correlation, thus revealing the ability of the formulation to reproduce the in-vitro release pattern through the in vivo. Conclusion: Glibenclamide muck-adhesive buccal films could be promising one as they, increase bioavailability by bypassing the first pass effect, minimize the dose, reduces the side effects, and improve patient compliance and also glibenclamide might be a right and suitable candidate for oral controlled drug delivery via buccoadhesive films.

Abstract
The present investigation highlights the novel trans-buccoadhesive films of Famotidine, an H2 receptor antagonist used as an anti-ulcerative agent. The buccal films were fabricated by solvent casting technique with different polymer combinations of hydroxypropyl methylcellulose, carbopol-934P and polyvinyl pyrrolidone. Drug–polymer interaction studies by Fourier transform infrared spectroscopy show that there is no significant interaction between drug and polymers. The fabricated films were evaluated for their physicochemical characters like weight, thickness, surface pH, percentage moisture absorption, percentage moisture loss, swelling percentage, folding endurance, water vapor transmission and drug content. Stability study of buccal films was performed in natural human saliva. Ex vivo permeation studies were conducted using fresh sheep buccal mucosa and buccoadhesive strength was calculated by modified balance method and showed sufficient strength in all the formulations. Good correlation was observed between the in vitro drug release and in vivo drug release, with a correlation coefficient of 0.995. Drug diffusion from buccal films showed apparently zero order kinetics and release mechanism was diffusion controlled after considerable swelling.

Abstract
Lamotrigine is a BCS class II drug with pH dependent solubility. The bilayered gastric mucoadhesive tablets of lamotrigine were designed such that the drug and controlled release polymers were incorporated in the upper layer and the lower layer had the mucoadhesive polymers. The major ingredients selected for the upper layer were the drug and control release polymer (either HPMC K15M or polyox) while the lower MA layer predominantly comprised of Carbopol 974P. A 2(3) full factorial design was constructed for this study and the tablets were optimized for parameters like tablet size, shape, ex vivo mucoadhesive properties and unidirectional drug release. Oval tablets with an average size of 14 mm diameter were set optimum. Maximum mucoadhesive bond strength of 79.3 ± 0.91 * 10(3) dyn/cm(2) was achieved with carbopol when used in combination with a synergistic resin polymer. All the tested formulations presented a mucoadhesion time of greater than 12 h. The incorporation of methacrylic polymers in the lower layer ensured unidirectional drug release from the bilayered tablets. The unidirectional drug release was confirmed after comparing the dissolution results of paddle method with those of a modified basket method. Model independent similarity and dissimilarity factor methods were used for the comparison of dissolution results. Controlled drug release profiles with zero order kinetics were obtained with polyox and HPMC K15M which reported t 90% at 6th and 12th hours, respectively. The "n" value with polyox was 0.992 and that with HPMC K15M was 0.946 indicating an approximate case II transport. These two formulations showed the potential for oral administration of lamotrigine as bilayered gastric mucoadhesive tablets by yielding highest similarity factor values, 96.06 and 92.47, respectively, between the paddle and modified basket method dissolution release profiles apart from reporting the best tablet physical properties and maximum mucoadhesive strength.

Abstract
Recent pharmaceutical research has focused on controlled drug delivery having an advantage over conventional methods. Adequate controlled plasma drug levels, reduced side effects as well as improved patient compliance are some of the benefits that these systems may offer. Controlled delivery systems that can provide zero-order drug delivery have the potential for maximizing efficacy while minimizing dose frequency and toxicity. Thus, zero-order drug release is ideal in a large area of drug delivery which has therefore led to the development of various technologies with such drug release patterns. Systems such as multilayered tablets and other geometrically altered devices have been created to perform this function. One of the principles of multilayered tablets involves creating a constant surface area for release. Polymeric materials play an important role in the functioning of these systems. Technologies developed to date include among others: Geomatrix(®) multilayered tablets, which utilizes specific polymers that may act as barriers to control drug release; Procise(®), which has a core with an aperture that can be modified to achieve various types of drug release; core-in-cup tablets, where the core matrix is coated on one surface while the circumference forms a cup around it; donut-shaped devices, which possess a centrally-placed aperture hole and Dome Matrix(®) as well as "release modules assemblage", which can offer alternating drug release patterns. This review discusses the novel altered geometric system technologies that have been developed to provide controlled drug release, also focusing on polymers that have been employed in such developments.

Abstract
Abstract
Objectives
The aim of this study was to assess the potential of a novel delivery device for administering drugs that suffer from a high degree of first-pass metabolism.
Methods
A tri-layered buccal mucoadhesive patch, comprising a medicated dry tablet adhered to a mucoadhesive film, was prepared and characterized by its physicochemical properties and mucoadhesive strength. Nicotine was used as a model drug for the characterization of drug release and drug permeation. The influence of different adsorbents on the release of nicotine base from the patches was evaluated in vitro. Different molecular forms of nicotine (base and complex salt) were evaluated for their effect on release performance and permeation in vitro.
Key findings
Results demonstrated acceptable physicochemical and mucoadhesive properties for the tri-layered patch. Rapid release of nicotine was observed when nicotine base was incorporated with calcium sulfate dihydrate as the adsorbent. Patches incorporating nicotine base showed distinct advantages over those containing nicotine polacrilex, in terms of drug release (complete drug release achieved at 30 vs 60 min) and transmucosal permeation (37.28 ± 4.25 vs 2.87 ± 0.26% of the dose permeating through mucosa within 120 min).
Conclusions
The novel tri-layered patch can effectively adhere to, and deliver an active ingredient through the buccal mucosa, confirming its potential for buccal mucoadhesive drug delivery.

Abstract
The buccal route of administration has a number of advantages including bypassing the gastrointestinal tract and the hepatic first pass effect. Mucoadhesive films are retentive dosage forms and release drug directly into a biological substrate. Furthermore, films have improved patient compliance due to their small size and reduced thickness, compared for example to lozenges and tablets. The development of mucoadhesive buccal films has increased dramatically over the past decade because it is a promising delivery alternative to various therapeutic classes including peptides, vaccines, and nanoparticles. The "film casting process" involves casting of aqueous solutions and/or organic solvents to yield films suitable for this administration route. Over the last decade, hot-melt extrusion has been explored as an alternative manufacturing process and has yielded promising results. Characterization of critical properties such as the mucoadhesive strength, drug content uniformity, and permeation rate represent the major research areas in the design of buccal films. This review will consider the literature that describes the manufacture and characterization of mucoadhesive buccal films.

Abstract
The aim of the present study was to develop and evaluate a buccal adhesive tablet containing ondansetron hydrochloride (OH). Special punches and dies were fabricated and used while preparing buccal adhesive tablets. The tablets were prepared using carbopol (CP 934), sodium alginate, sodium carboxymethylcellulose low viscosity (SCMC LV), and hydroxypropylmethylcellulose (HPMC 15cps) as mucoadhsive polymers to impart mucoadhesion and ethyl cellulose to act as an impermeable backing layer. The formulations were prepared by direct compression and characterized by different parameters such as weight uniformity, content uniformity, thickness, hardness, swelling index, in vitro drug release studies, mucoadhesive strength, and ex vivo permeation study. As compared with the optimized formulation composed of OH--5 mg, CP 934--30 mg, SCMC LV--165 mg, PEG 6000--40 mg, lactose--5 mg, magnesium stearate--1.5 mg, and aspartame--2 mg, which gave the maximum release (88.15%), non-bitter (OH) that form namely ondansetron base and complexed ondansetron was used in order to make the selected formulation acceptable to human. The result of the in vitro release studies and permeation studies through bovine buccal mucosa revealed that complexed ondansetron gave the maximum release and permeation. The stability of drug in the optimized adhesive tablet was tested for 6 h in natural human saliva; both the drug and device were found to be stable in natural human saliva. Thus, buccal adhesive tablet of ondansetron could be an alternative route to bypass the hepatic first-pass metabolism and to improve the bioavailability of (OH).
