The present review is focused on the prebiotic impact of inulin on the management of the gastrointestinal disorder. Prebiotics can be described as "non-digestible food ingredient stimulating the growth of a certain number of bacteria in the colon, which can improve the host health". In 2004 this definition was modernized to include other areas that may benefit from selective targeting of particular microorganisms: "selectively fermented ingredients that alter the configuration and activity in the gastrointestinal microbiota that confer positive effect". The positive impact of prebiotics in experimental colitis and human inflammatory bowel disease (IBD) has already been established. Prebiotics shows a positive effect in the prevention of IBD by modulating the trophic functions of the flora. Inulin enhances the growth of indigenous lactobacilli and/or bifidobacteria by inducing colonic production of short chain fatty acids (SCFA's) and these properties are related to decreased mucosal lesion scores and diminished mucosal inflammation. Inulin shows a positive approach to retain microbial populations and to support epithelial barrier function by their prebiotic effect which helps in the host defense against invasion and pathogens translocation (endogenous and/or exogenous) and in the inhibition of gastrointestinal diseases and this impact should be verified in further clinical studies. In the present review, we discussed the positive effect of prebiotics in rat IBD models and in human subjects along with their potential protective mechanisms. Preclinical and clinical data revealed that the gut mucosal barrier would be improved by the use of prebiotics in IBD.
The delivery of a drug to the preferred site of action is referred to as drug targeting. The benefits of drug targeting are a reproducible and controlled release rate of the therapeutic compound, which forestalls overdose. Due to the potential to treat colonic diseases with minimum side effects, colon targeting has become of high interest over the last decades. Inulin was investigated for its potential as encapsulation material regarding its enzymatic degradability and its drug release behaviour. Inulin is a polysaccharide with a widespread range of therapeutic uses such as a carrier in a drug delivery vehicle, as a diagnostic/analytical tool or as a dietary fibre with additional health benefits. In the main, much research has focused on inulin as a drug delivery carrier for colon-specific drug delivery. The justification for this is its potential to survive in the stomach’s acidic environment. This unique stability and strength are utilized in many ways to deliver drugs safely to the colon, where they can be easily absorbed through the gut epithelium into the blood. There are also some proofs that inulin’s prebiotic features also lead to health benefits, mainly for patients with inflammatory bowel disease or in the prevention of colonic cancer. Inulin based hydrodynamic research will be useful to discover the potential of inulin.
Background Present investigation for research was to develop matrix-type transdermal drug delivery system of flurbiprofen (FBP) with the various ratio of matrix polymers (hydrophilic and hydrophobic), the concentration of plasticizer and natural penetration enhancer by Box–Behnken statistical design to investigate the combined outcome of selected independent variables for effective management of rheumatoid arthritis. The influence of a binary mixture of polymers, plasticizer and penetration enhancer on physicochemical considerations including thickness, tensile strength, percent elongation, weight variation, percent moisture content, percent moisture uptake, water vapour transmission rate, folding endurance, drug content, in vitro drug dissolution study and then ex vivo drug permeation study was evaluated. Results The study demonstrated that the tensile strength of films improved by matrix polymer ratio and to a slighter gradation in the rise of plasticizer and natural penetration enhancer. Ex vivo drug permeation study was accompanied via excised porcine skin as a permeation barrier in Franz diffusion cell. Ex vivo drug permeation study indicated that matrix polymer ratio (HPMC K15M:ERL100) at 3:1 and natural penetration enhancer (d-limonene) at highest concentration 7.5% w/w containing formulation FBPT7 delivered maximum flux and supplementary improved the permeation of drug. The result of the skin irritation test revealed that the developed formulation is free from any type of skin irritation effects like erythema and oedema. Conclusion Based on the findings of this research, it can be established that a well-controlled release and very effective skin penetration of the drug was accomplished by the film FBPT7 in the existence of permeation enhancers for prolonged periods.
The prime goal of drug delivery through drug carrier system to the specific target site at the suitable concentration for therapeutic action. Recently thin films are acquiring attention as drug carrier and various scientists are working on the formulation and development of thin films as a novel drug delivery system. Because of its capacity to safely load medications and release them in a regulated manner, thin films have attracted increasing interest in the field of drug delivery, which improves drug efficacy. They are more patient compliance and alternative to oral drug delivery employing self-application, prolonged action and easily terminate if drug toxicity is produced. Oral, buccal, sublingual, ocular, and transdermal routes have all been employed to deliver this delivery mechanism for both systemic and local effects. The development of thin films comprises of various methods with keeping in mind the anatomical and physiological constraints, physicochemical properties and types of drug substance and use of various polymers (matrix, hydrophilic and hydrophobic) as well as the characterisation methods with recent trends.
Background: The goal of the current investigation was to formulate, evaluate co-crystal, and further design of solid unit dosage form of antihyperlipidemic BCS class II drug fenofibrate (FNO). Co-crystals composed of a structurally homogeneous crystalline material that contains two or more components in a definite stoichiometric amount helps in increasing yield, the capability to regulator polymorph fabrication, enhanced invention crystallinity. Ball milling method is used for co-crystal formulation, optimized via 3 2 full factorial design and characterized by saturation solubility, particle size analysis, Fourier transform infrared spectroscopy (FT-IR) study analysis, powder X-ray diffraction (PXRD) study analysis, surface morphology by scanning electron microscopy (SEM) study, flow properties, and ex vivo intestinal permeation study via non-everted rat intestinal sac model. Furthermore, optimized batch compressed into tablets is evaluated for disintegration time, hardness, friability, in vitro drug release study and stability study. Results: It demonstrated that co-crystal formulation FNOCC7 shows higher saturation solubility 0.3874 ± 2.82 g/ml with less particle size 221.231 ± 0.456 nm, FT-IR spectra confirmed significant structural alterations in the formulation indicating the hetero-molecular interaction, the presence of hydrogen bonding had occurred in the cocrystals, PXRD spectra of formulation determined by the increase in the crystalline nature. FNO co-crystals show flux (F) and permeability coefficient (P app) 0.322 ± 0.068 μg/min, 5.38 ± 0.093 cm/min respectively increased compared to the pure drug makes in an enhancement of solubility as well as the bioavailability of BCS class II drug. Conclusions: The solubility and dissolution percentage of FNO can be improved by the utilization of Co-crystal of FNO with PEG 4000. The solubilization impact of PEG 4000 might be contributed because of the decrease of molecule conglomeration of the drug presence of crystallinity, expanded wettability, and dispersibility; pharmaceutical co-crystals speak to a beneficial class of crystal form with regard of pharmaceuticals.
