Design, characterization and in vivo performance of solid lipid nanoparticles (SLNs)-loaded mucoadhesive buccal tablets for efficient delivery of Lornoxicam in experimental inflammation. Int J Pharm 2022; 624:122006. [PMID: 35820515 DOI: 10.1016/j.ijpharm.2022.122006] [Citation(s) in RCA: 31] [Impact Index Per Article: 15.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 06/06/2022] [Accepted: 07/05/2022] [Indexed: 12/27/2022]
Abstract
Lornoxicam (LRX) is a potent nonsteroidal anti-inflammatory drug (NSAID) used extensively to manage pain and inflammatory conditions. However, the drug possesses poor aqueous solubility (i.e., BCS class II) and a short half-life (3-4 h). Mucoadhesive buccal tablets containing LRX -loaded solid lipid nanoparticles (SLNs) were developed to enhance the drug solubility and bioavailability and achieve a controlled release pattern for a better anti-inflammatory effect. Different LRX-loaded SLNs were prepared using the hot homogenization /ultra-sonication technique and evaluated using size analysis and entrapment efficiency (EE%). Optimized LRX -loaded SLNs formulation showed particle size of 216 ± 7.4 nm, zeta potential of -27.3 ± 4.6 mV, and entrapment efficiency of 92.56 ± 2.3 %. Dried LRX-loaded SLNs alongside mucoadhesive polymers blend (PVP K30 /HPMC K15) were compressed to prepare the mucoadhesive buccal tablets. The tablets showed proper physicochemical properties, good mucoadhesive strength, long mucoadhesive time, suitable pH surface, good swelling capacity, and controlled drug release profile. Furthermore, Fourier transform-infrared (FTIR) spectroscopy, Powder X-Ray diffraction (PXRD), and Scanning electron microscopy (SEM) studies were carried out. The in vivo anti-inflammatory effect of pure LRX, market LRX and optimized mucoadhesive buccal tablet of LRX -loaded SLNs (T3) against carrageenan-induced models were evaluated. T3 showed a significant and early anti-inflammatory response after 1 and 2 h (63.62-77.84 % inhibition) as well as an extended effect after 4 h as compared to pure and market LRX. In parallel, T3 showed the best amelioration of PGE2, COX2, and TNF-α serum levels after 4 h of carrageenan injection.

Abstract
Abstract
Nystatin is an antifungal agent used for prophylaxis and treatment of candidiasis, especially oral mycosis. Efficacy of nystatin conventional dosage forms is limited by the short residence time and bitter taste of the drug. This research aims at designing an optimized formulation of oral mucoadhesive gel of nystatin-loaded alginate microparticles, which can be retained in the mouth. Sodium alginate solution containing nystatin was added to the solution of calcium chloride under stirring. Microparticles containing nystatin were incorporated into the Carbopol gel. Size, loading, and release profile and mucoadhesion were investigated. The most suitable microparticles with particle size of < 250 μm were prepared with alginate concentration of 1%(w/v), calcium chloride of 1%(w/v), drug:polymer concentration 1%, and ratio of alginate solution:calcium chloride of 1:10. This formulation showed 49.1% drug loading and 98.2% encapsulation efficiency. Carbopol 934 gel provided optimal mucoadhesive properties. Release profile proved a burst release, which can be attributed to the surface associated drug, followed by a slower sustained release phase for all microparticles. The developed system with ability to adhere to the oral mucosa has great appeal for treatment of localized infections and can mask bitter taste of the drug and be retained in the mouth for long periods.

Abstract
In this study, buccal mucoadhesive tablets of meloxicam were formulated for drug delivery as an alternative route. Direct compression method was applied for the preparation of tablets. Also, different polymers, including hydroxypropyl methyl cellulose (HPMC) 1000, 4000, and 10000, as well as carbopol 934p and carbopol 971p were used as the mucoadhesive polymer and retardant polymer. Thirteen formulations were investigated with various concentrations of polymers. The physicochemical characteristics, in-vitro drug release, swelling index, and taste modification of tablets were evaluated. Also, Carr’s index and Hausner ratio were studied. In addition, zero-order, first-order, and Higuchi kinetics were investigated and the results showed that the highest correlation coefficient (R2) is related to zero-order kinetic for formulations B2 and B3. Furthermore, the highest R2 is related to Higuchi kinetic for formulation C3. Formulation B2 showed the maximum release of 99% in 12 h. The results demonstrated that Formulation B2 can be considered as a proper buccal mucoadhesive tablet of meloxicam with desired property.

Abstract
The treatment of canker sores can be quite compromised by the short period of the drug in the place of action. In this context, there is a need to develop drug dosage forms that allow more contact with the oral mucosa providing prolonged drug release. Therefore, the aim of this work was to obtain and characterize buccal films based on pectin and gellan gum in order to evaluate the potential use of these natural polymers in the production of pharmaceutical dosage forms for controlled release of TA in the oral mucosa. Using a 23 full factorial design, eight formulations were prepared by solvent casting method. The raw materials and films were characterized using techniques such as FTIR, DSC, and TG. In addition, thickness, mechanical properties, mucoadhesive strength, swelling, drug content, and dissolution profile of the films were evaluated. The results of FTIR, DSC, and TG showed that new chemical species are not formed in the production of films, and that these dosage forms have an adequate thermal behavior. All formulation showed a high degree of swelling, good mechanical resistance and elasticity, and a good mucoadhesive strength as well as able to act as a controlled release system.

Abstract
Enterovirus 71 (EV71) is a pathogenic factor of severe hand, foot, and mouth disease (HFMD). No vaccine or specific treatment is currently available for EV71 infection. Hence, we developed a buccal mucoadhesive gel containing matrine to protect against HFMD. Mucoadhesive gels were prepared by Carbopol 974P and were combined with Carbopol 971P, sodium carboxymethyl cellulose (CMC-Na), or hydroxypropylmethy cellulose (HPMC K100M). The formulations were characterized in terms of tensile testing and continuous flow techniques for mucoadhesion. The rheological studies and in vitro drug release characteristics were also investigated. The results showed that combinations of two polymers significantly improved mucoadhesion, especially Carbopol 974P blended with HPMC. Carbopol 974P to HPMC blend ratios of 1:1 and 2:1 induced better mucoadhesion in the tensile test and continuous flow method, respectively. The most sustained release was obtained at a Carbopol 974P to HPMC ratio of 2.5:1. A predominantly non-Fickian diffusion release mechanism was obtained. The gel containing 2.5% Carbopol 974P combined with 1% HPMC showed good mucoadhesion properties and sustained drug release.

Abstract
Hypertension crisis is one of the main health problems and its effective treatment is of high importance. For this purpose, fast-disintegrating and sustained release formulations of captopril, as a drug of choice, were prepared using conventional mucoadhesive polymers hydroxypropyl methylcellulose (HPMC), sodium carboxymethyl cellulose (Na-CMC), hydroxypropyl cellulose (HPC), Carbopol 934 (CP934) and sodium alginate (Na-alg). The optimum sustained release formulations were selected based on mean dissolution time (MDT). The swellability and mucoadhesive properties of selected formulations were assessed and compared. A direct relationship between swelling and release rates/adhesiveness of sustained release formulations was observed. The results showed that formulations containing combination of CP934 and cellulose-based polymers had the highest swellability, sustainability and adhesion strength. These formulations prolonged drug release up to 8 h showing good fitness to Korsemeyer-Peppas model. Moreover, the adopted fast-disintegrating tablet could release up to 100% of drug within 3 min in oral pH. Finally, a dual fast-disintegrating/sustained release bucoadhesive bilayer tablet consisting of optimized formulations was prepared releasing 30% of the drug initially within 15 min and the remaining up to 8 h which could be considered as an appropriate formulation for the treatment of hypertension crises.

Abstract
INTRODUCTION Several studies towards the development of an effective treatment for intestinal mucositis have been reported, since this condition represents a major problem in clinical oncology practice due to cytotoxic effects of chemotherapy. However standardized protocols and universally accepted treatment options are yet to be established. OBJECTIVES Given above, this study evaluated the protective effects of a mucoadhesive formulation containing both Bidens pilosa L. (Asteraceae) (BP) and curcuminoids from Curcuma longa L. (Zingiberaceae) (CL) on intestinal mucositis induced by 5-fluoruoacil (5-FU) in mice. RESULTS As expected, animals only treated with 5-FU (200 mg/kg) showed a significant reduction of 60.3 and 42.4% in villi and crypts size, respectively, when compared to control. On the other hand, the proposed therapeutic/prophylactic treatment with mucoadhesive formulations managed to reduce histopathologic changes in mice bearing mucositis, especially at 125 mg/kg BP + 15 mg/kg CL dose. The formulation promoted an increase of 275.5% and 148.7% for villi and crypts size, respectively. Moreover, chemotherapy-related weight loss was reduced by 7.4% following the treatment. In addition, an increase of 10 and 30.5% in red and white blood cells was observed when compared to 5-FU group. Furthermore, treatments with the mucoadhesive formulation containing BP/CL up modulated Ki-67 and Bcl-2 expression while reduced pro-apoptotic regulator Bax. The formulation also modulated inflammatory response triggered by 5-FU through reduction of 68% of myeloperoxidase activity and a 4-fold increase in anti-inflammatory IL-10 levels. In parallel, the oxidative stress via lipid peroxidation was reduced as indicated by decrease of 63% of malondialdehyde concentrations. Additionally, the new formulation presented low acute oral systemic toxicity, being classified in the category 5 (2000 mg/kg < LD50 < 5000 mg/kg) of the Globally Harmonized Classification System. CONCLUSIONS This study showed an interesting potential of the mucoadhesive formulation of BP/CL for the treatment of 5-FU-induced intestinal mucositis. Given the perspectives for the development of a new medicine, clinical studies are in progress to better understand the protective effects of this innovative formulation in treating mucositis.

Abstract
The conventional formulation of prednisolone is considered to be low in efficacy, primarily on account of their failure in providing and maintaining effective therapeutic drug levels. This study aims to focus on development of a mucoadhesive buccal delivery system with a twofold objective of offering a rapid as well as a prolonged delivery of prednisolone coupled with enhanced therapeutic efficacy. Buccoadhesive films of prednisolone were prepared by solvent-casting method using hydroxyl propyl methyl cellulose (K100), Carbopol 940 and/or Eudragit NE 40 D. Placebo films possessing the most desirable physicomechanical properties were selected for drug loading. The effect of polymer and its content on film properties, i.e. mucoadhesive strength, swelling and hydration, in vitro drug release was studied. Based on these studies, film F7D was selected for ex vivo permeation across porcine cheek mucosa. The steady state flux of prednisolone across the buccal mucosa was found to be 105.33 ± 32.07 µg/cm(2)/h. A comparative pharmacokinetic study of prepared film (F7D) and oral suspension of prednisolone was conducted. In vivo data of buccal film show greater bioavailability (AUC0-α: 24.26 ± 4.06 µg.h/ml versus 10.65 ± 2.15 µg.h/ml) and higher Cmax (2.70 ± 0.38 µg/ml versus 2.29 ± 0.32 µg/ml) value when compared to oral suspension. The data observed from this study highlight the feasibility of the buccal route as a viable option for delivery of prednisolone.

Abstract
INTRODUCTION The oral mucosa is an appropriate route for drug delivery systems, as it evades first-pass metabolism, enhances drug bioavailability and provides the means for rapid drug transport to the systematic circulation. This delivery system offers a more comfortable and convenient delivery route compared with the intravenous route. Although numerous drugs have been evaluated for oral mucosal delivery, few of them are available commercially. This is due to limitations such as the high costs associated with developing such drug delivery systems. AREAS COVERED The present review covers recent developments and applications of oral transmucosal drug delivery systems. More specifically, the review focuses on the suitability of the oral soft palatal site as a new route for drug delivery systems. EXPERT OPINION The novelistic oral soft palatal platform is a promising mucoadhesive site for delivering active pharmaceuticals, both systemically and locally, and it can also serve as a smart route for the targeting of drugs to the brain.

Abstract
Buccoadhesive gels for transbuccal delivery of glipizide were prepared using different bio-adhesive polymers. The gels were prepared by solution polymerization technique. An apparatus simulating the in vivo conditions of the mouth was designed in order to assess in vitro drug release kinetics of these gels. The gels were also evaluated for spreadability, buccoadhesive strength, swelling index, and viscosity. Maximum buccoadhesive strength was observed for formulation, F8 with good sustained release behavior, whereas viscosity and swelling index was highest for the formulation, F5 but with minimum buccoadhesive strength. The drug release kinetics followed Higuchi model with release mechanism being Fickian diffusion.

Abstract
BACKGROUND & AIMS SPD476 (MMX mesalamine), a novel, once-daily mesalamine formulation, uses MMX Multi Matrix System (MMX) technology to delay and extend delivery of active drug throughout the colon. We performed a randomized, double-blind, parallel-group, placebo-controlled, multicenter phase III study in patients with mild to moderately active ulcerative colitis. METHODS Two hundred eighty patients with mild to moderately active ulcerative colitis received MMX mesalamine 2.4 g/day given twice daily (n = 93), 4.8 g/day given once daily (n = 94), or placebo (n = 93) for 8 weeks. The primary end point was the percentage of patients in clinical and endoscopic remission (modified ulcerative colitis disease activity index score of < or =1, with a score of 0 for rectal bleeding and stool frequency, and at least a 1-point reduction in sigmoidoscopy score) at week 8. Patients with mucosal friability were not considered to have achieved this end point. RESULTS Clinical and endoscopic remission at week 8 was achieved by 34.1% and 29.2% of patients receiving MMX mesalamine 2.4 g/day given twice daily and MMX mesalamine 4.8 g/day given once daily, respectively, versus 12.9% receiving placebo (P < .01). MMX mesalamine was generally well-tolerated. CONCLUSIONS MMX mesalamine given once or twice daily is well-tolerated and, compared with placebo, demonstrated efficacy for the induction of clinical and endoscopic remission in mild to moderately active ulcerative colitis.

Abstract
BACKGROUND & AIMS SPD476 (LIALDA in the US; MEZAVANT in the EU; otherwise known as MMX mesalamine; Shire Pharmaceuticals Inc., Wayne, PA, under license from Giuliani SpA, Milan, Italy) is a novel, once-daily, high-strength (1.2 g/tablet) formulation of mesalamine, utilizing MMX Multi Matrix System (MMX) technology designed to deliver the active drug throughout the colon. We performed a double-blind, multicenter study, comparing MMX mesalamine vs placebo for the treatment of active ulcerative colitis. A delayed-release oral mesalamine (ASACOL; Procter & Gamble, Cincinnati, OH) reference arm was included. METHODS Three hundred forty-three patients with active, mild-to-moderate ulcerative colitis received MMX mesalamine 2.4 g/day or 4.8 g/day given once daily, ASACOL 2.4 g/day given in 3 divided doses, or placebo for 8 weeks. The primary end point was the proportion of patients in clinical and endoscopic remission (modified ulcerative colitis disease activity index of < or =1 with rectal bleeding and stool frequency scores of 0, no mucosal friability, and a > or =1-point reduction in sigmoidoscopy score from baseline). RESULTS A significantly greater proportion of patients receiving MMX mesalamine 2.4 g/day given once daily (40.5%; P = .01) and 4.8 g/day given once daily (41.2%; P = .007) achieved clinical and endoscopic remission at week 8, vs placebo (22.1%). The clinical and endoscopic remission rate for ASACOL (32.6%; P = .124) was not significantly superior to placebo. All active treatments were well-tolerated. CONCLUSIONS Once-daily MMX mesalamine was efficacious and well-tolerated for the induction of clinical and endoscopic remission. MMX mesalamine offers effective and convenient mesalamine therapy, potentially improving treatment compliance.

Abstract
BACKGROUND SPD476 (MMX mesalazine), is a novel, once daily, high-strength mesalazine formulation (1.2 g/tablet) that utilizes Multi Matrix System (MMX) technology to delay and extend delivery of the active drug throughout the colon. AIM To assess the safety and efficacy of MMX mesalazine in patients with mild-to-moderately active ulcerative colitis, in a pilot, phase II, randomized, multicentre, double-blind, parallel-group, dose-ranging study (SPD476-202). METHODS Thirty-eight patients with mild-to-moderately active ulcerative colitis were randomized to MMX mesalazine 1.2, 2.4 or 4.8 g/day given once daily for 8 weeks. Remission ulcerative colitis-disease activity index (UC-DAI) < or =1, a score of 0 for rectal bleeding and stool frequency, and > or =1 -point reduction in sigmoidoscopy score from baseline was the primary end point. RESULTS Week 8 remission rates were 0%, 31% and 18% of patients receiving MMX mesalazine 1.2, 2.4 and 4.8 g/day respectively. No statistically significant difference in remission was observed between treatment groups. MMX mesalazine 2.4 and 4.8 g/day groups demonstrated greater improvement in overall UC-DAI and component scores from baseline, compared with the 1.2 g/day group. CONCLUSION MMX mesalazine given as 2.4 or 4.8 g/day once daily is well tolerated and effective for the treatment of mild-to-moderately active ulcerative colitis.
