Budesonide belongs to low-bioavailability steroids class. A novel oral formulation of budesonide, which uses the Multi-Matrix System (MMX) for delivering drugs to the colon, is now available as a possible treatment of ulcerative colitis patients intolerant or not-responding to first-line therapy with 5-ASA. Areas covered: in this review we present information about the development and the use of budesonide MMX and we provide data about its mechanism of action as well as, pharmacodynamics and pharmacokynetics...

The aim of this work is to develop a drug-loaded silk fibroin fibrous membrane (DSFM) that can be attached to the surface of an anal fistula plug to improve the treatment of Crohn's disease (CD). Curcumin (CUR) and 5-aminosalicylic acid (5-ASA)-loaded silk fibroin (SF) membranes are coaxially electrospun onto the surface of a braided silk filament plug. The membranes show a predominant structure of random coil and silk I conformation. The concentration of CUR/5-ASA (weight ratio of 1/1) in the SF solution is optimized to 0...

We have carried out an analysis of whether blood IgG antibodies can protect humans from oxidative stress by oxidizing different harmful compounds. A somewhat unexpected result was obtained. We show here for the first time that healthy human sera IgGs with the peroxidase (in the presence H2O2) efficiently oxidize different compounds: 3,3'-diaminobenzidine (1; DAB), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (2; ATBS), o-phenylenediamine (3; OPD), homovanillic acid (4; HVA), α-naphthol (5), 5-aminosalicylic acid (6; 5-ASA) and 3-amino-9-ethylcarbazole (7; AEC), but seven of nine IgG preparations from different volunteers cannot oxidize p-hydroquinone (8: pHQ)...

The widespread occurrence of pharmaceuticals and their metabolites in natural waters has raised great concerns about their potential risks on human health and ecological systems. This study systematically investigates the degradation of sulfasalazine (SSZ) and its two human metabolites, sulfapyridine (SPD) and 5-aminosalicylic acid (5-ASA), by UV and UV/peroxydisulfate (UV/PDS) processes. Experimental results show that SPD and 5-ASA were readily degraded upon UV 254 nm direct photolysis, with quantum yields measured to be (8...

To develop a new strategy for inflamed site-specific drug delivery in the colon for the treatment of ulcerative colitis (UC), we leveraged on the interaction between myeloperoxidase (MPO) and human serum albumin (HSA) and prepared nanoparticles (HSA NPs) conjugated with 5-aminosalicylic acid (5-ASA). The 5-ASA-HSA NPs (nine molecules of 5-ASA per HSA molecule) were uniform particles with an average particle size of 190 nm, a zeta potential of -11.8 mV, and a polydispersity index of 0.35. This was considered a suitable particle characteristic to pass through the mucus layer and accumulate into the mucosa...

Adequate release of 5-ASA in colon is challenging as it easily permeates at the acidic pH of the upper gastrointestinal tract. Targeting delayed release of 5-ASA at acidic pH, Carboxymethyl cellulose-rosin gum hybrid nanoparticles (CRNP3) with an average size of 267 nm have been crafted through nanoprecipitation method. CRNP3 was extensively characterized using Fourier Transform Spectroscopy (FTIR), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and particle size analysis based on dynamic light scattering...

Obesity is associated with a series of metabolic complications, including dyslipidemia and insulin resistance (IR) that lack effective therapies. In recent years, intestinal inflammation has been suggested to contribute to obesity related metabolic syndrome and targeting gut inflammation with 5-ASA improves diet induced IR, however, its role in dyslipidemia is unknown and has never been explored. In the present study, we reported for the first time that administration of 5-ASA for 12 weeks significantly improved lipid profile by repressing plasma triglycerides and free cholesterol levels in mice fed high-fat cholesterol diet (HFC)...

Many active pharmaceutical ingredients (API) exhibit a needle-like (acicular) crystal habit, which can significantly complicate their downstream processing. In this study, the acicular crystal habit of a model API, 5-aminosalicylic acid (5-ASA), was modified by addition of selected organic solvents to the typical aqueous crystallization process. 5-ASA was crystallized by a pH shift from 7.5-8 to 4 in the presence of methanol, acetonitrile, acetone, tetramethylurea (TMU), tetrahydrofuran (THF) or dimethyl sulfoxide (DMSO) at 25% v/v, or butanol at 9% v/v...

Inflammatory bowel disease (IBD) causes inflammation to the gastrointestinal tract. Local administration of Anti-inflammatory drugs such as 5-aminosalysilic acid (5-ASA) can alleviate the symptoms of IBD. The application of nanoparticles for IBD treatment in direct rectal administration showed high drug availability and treatment efficacy. However, relying on size-dependent adsorption of smaller particles is not sufficient for making the formulation capable of targeting. Intestinal organoids can improve the functionality of the nanoparticles due to their ability to adsorb small nanoparticle inside the lumen and attach to the damaged area...

BACKGROUNDS: In some patients with ulcerative proctitis (UP), skip inflammation is noted in the right side of the colon, but little is known about its clinical course. The aim of this study was to evaluate the clinical course of UP with skip inflammation and the efficacy of topical 5-ASA monotherapy. METHODS: We reviewed the data of 388 patients with an initial diagnosis of UP from January 2005 to October 2015. We matched each UP patient with skip inflammation 1:2 with controls who had UP without skip inflammation; to reduce bias, we matched the controls with the cases by age, gender, and initial disease activity...

INTRODUCTION: Chronic beryllium disease (CBD) is characterized by accumulation of macrophages and beryllium-specific CD4(+) T cells that proliferate and produce Th1 cytokines. 5-Amino salicylic acid (5-ASA) is currently used to treat inflammatory bowel disease and has both antioxidant and anti-inflammatory actions. We hypothesized that 5-ASA may be a beneficial therapeutic in CBD. METHODS: Seventeen CBD patients were randomized 3:1 to receive 5-ASA 500-mg capsules or placebo four times daily for 6 weeks orally...

Adherence is pivotal but challenging in ulcerative colitis (UC) treatment. Many methods to assess adherence are subjective or have limitations. (Nac-)5-aminosalicylic acid (5-ASA) urinalysis by High-Performance Liquid Chromatography (HPLC) seems feasible and reproducible in healthy volunteers. We performed a prospective study in adult quiescent UC patients to evaluate the feasibility of spot (Nac-)5-ASA urinalysis by HPLC to assess adherence in daily IBD care. Twenty-nine patients (51.7% male, mean age 52 ± 11 yrs) were included (median FU 9 months) and collected weekly spot urine samples...

Given the central role of gluten in the pathogenesis of celiac disease (CD), a strict gluten-free diet (GFD) is the only validated treatment able to restore epithelium integrity and eliminate risks of complications. The risk of gluten contamination and the persistence of inflammation, even in patients strictly adhering to GFD, may render this treatment not always effective claiming the necessity of different new solutions. Oxidative and nitrosative stress have been indicated to play a pathophysiological role in CD...
