BACKGROUND: Trials in adults suggested once-daily (QD) dosing of 5-ASA may be as or more effective as twice-daily (BID) dosing in ulcerative colitis (UC). In this induction of remission, investigator-blinded, randomized-controlled-trial we aimed to compare effectiveness and safety of once vs. twice daily mesalazine (Pentasa®), in paediatric UC. METHODS: Children, 4-18 years with a PUCAI ( Paediatric Ulcerative Colitis Activity Index) of 10-55 points at inclusion, were randomized in blocks of 6 with blinded allocation to QD or BID mesalamine using a weight-based dosing table...

BACKGROUND: Oral 5-aminosalicylic acid (5-ASA) preparations were intended to avoid the adverse effects of sulfasalazine (SASP) while maintaining its therapeutic benefits. Previously, it was found that 5-ASA drugs in doses of at least 2 g/day, were more effective than placebo but no more effective than SASP for inducing remission in ulcerative colitis. This updated review includes more recent studies and evaluates the efficacy and safety of 5-ASA preparations used for the treatment of mild to moderately active ulcerative colitis...

A 19-year-old woman presented to our emergency department with crampy abdominal pain and per rectal bleeding 2 weeks after falling from a horse. She had been taking regular non-steroidal anti-inflammatory drugs (NSAIDs) for analgaesia. On arrival, she was tachycardic and tachypnoeic, with a lactate of 7.3 mmol/L. 'FAST' ultrasonography was unremarkable and CT scan showed thickened wall of the transverse colon. She underwent flexible sigmoidoscopy, which demonstrated "patchy inflammation and an isolated area of severe deep ulceration with nodularity and oedema"...

INTRODUCTION: Oral formulations of 5-aminosalicylic acid (5-ASA) for treatment of ulcerative colitis have been developed to minimize absorption prior to the drug reaching the colon. In this study, we investigate the release of 5-ASA from available oral mesalamine formulations in physiologically relevant pH conditions. METHODS: Release of 5-ASA from 6 mesalamine formulations (APRISO®, Salix Pharmaceuticals, Inc., USA; ASACOL® MR, Procter & Gamble Pharmaceuticals UK Ltd...

The aminosalicylate mesalazine (mesalamine) forms the mainstay of treatment in ulcerative colitis (UC), a disease for which many commercial modified-release products have been developed with the aim of providing targeted gastrointestinal release. The release profiles of five of these commercial formulations were evaluated in bicarbonate buffer using a novel dissolution model that mimics the dynamic conditions of the gastrointestinal tract. Monolithic and multi-particulate mesalazine formulations with pH-dependent and/or independent release mechanisms were evaluated (Asacol(®) 800, Octasa(®), Mezavant(®) XL, Salofalk(®), Pentasa(®)), and each of the products displayed a distinctive dissolution profile...

Prediction of the in vivo performance of the drug product from the in vitro studies is the major challenging job for the pharmaceutical industries. From the current regulatory perspective, biorelevant dissolution media should now be considered as quality control media in order to avoid the risk associated. Physiological based pharmacokinetic models (PBPK) coupled with biorelevant dissolution medium is widely used in simulation and prediction of the plasma drug concentration and in vivo drug performance. The present investigation deals with the evaluation of biorelevant dissolution media as well as in vivo drug performance by PBPK modelling using STELLA® simulation software...

The first proof of concept in vivo for a new type of microbiota-sensitive film coatings allowing for colon targeting is presented. The efficacy of these polysaccharide barriers to optimize drug release for the treatment of inflammation is demonstrated in an experimental colitis model with Wister rats. 5-Aminosalicylic acid (5-ASA) pellets were prepared by extrusion-spheronization and coated with Nutriose:ethylcellulose (EC) 1:4 or peas starch:ethylcellulose 1:2 blends. The pellets were mixed with standard chow, and the daily drug dose was 150mg/kg...

Crohn's disease (CD) may involve any part of the gastrointestinal tract, from the mouth to the anus. Approximately >90% of cases occur in the small bowel and colon. Upper gastrointestinal involvement, especially duodenal manifestation, is relatively rare. Therefore, adequate medical treatment for duodenal CD has not yet been established. We report a case of CD with duodenal involvement. A 46-year-old man with Crohn's ileocolitis presented to our hospital with right upper quadrant pain. An endoscopy showed a deep excavated ulcer with deformity at the duodenal bulb, and he was initially treated with azathioprine (1 mg/kg), Pentasa (3...

REVIEW
Stephan Karl Böhm, Wolfgang Kruis
In 1977, 5-aminosalicylic acid (5-ASA) was discovered as a therapeutically active moiety of sulfasalazine (SASP) and was launched for topical and oral therapy of ulcerative colitis (UC) in 1984. As a first-step, delivery systems had to be developed to protect 5-ASA against absorption in the upper gastrointestinal tract, resulting in different and competing strategies (azo compounds, controlled release, and pH-dependent release). In a second step, at the beginning of the new century, coinciding with the expiration of patent protection for the first 5-ASA formulations, two component composite release mechanisms (pH-dependent and controlled release) were developed...

BACKGROUND: High-dose (4.0 g/day) mesalazine is typically used for induction therapy, but its efficacy as maintenance therapy remains to be determined. We conducted a multicenter retrospective study to investigate the efficacy of continuous treatment with 4.0 g/day of mesalazine. MATERIAL/METHODS: Japanese ulcerative colitis (UC) patients receiving acute induction therapy with 4.0 g/day mesalazine were enrolled and followed. Those who clinically improved or who achieved clinical remission were categorized into 2 sub-groups according to the median duration of treatment with 4...

Mesalamine-containing products are considered first-line treatment for inflammatory bowel disease. Myocarditis is recognised as a very rare possible side effect of these medications, but has not often been described in the paediatric population. We present a case of an adolescent with Crohn's disease who presented with myopericarditis after recent initiation of Pentasa. Once identified as the causative agent, the drug was discontinued, with subsequent normalisation of troponin and improvement of function. This case identifies the importance of prompt evaluation, diagnosis, and treatment of paediatric patients receiving mesalamine-containing medications that present with significant cardiovascular symptoms...

CONTEXT: Unspecified Ulcerative Rectocolitis is a chronic disease that affects between 0.5 and 24.5/105 inhabitants in the world. National and international clinical guidelines recommend the use of aminosalicylates (including mesalazine) as first-line therapy for induction of remission of unspecified ulcerative rectocolitis, and recommend the maintenance of these agents after remission is achieved. However, multiple daily doses required for the maintenance of disease remission compromise compliance with treatment, which is very low (between 45% and 65%)...

BACKGROUND: Aminosalicylates are first-choice treatment for mild-to-moderately active ulcerative colitis (UC); however, multi-dosing regimens are inconvenient. AIM: To compare the efficacy and safety of once- (OD) vs. twice- (BD) daily prolonged-release mesalazine (Pentasa, Ferring, Saint-Prex, Switzerland) for active mild-to-moderate UC in a non-inferiority study. METHODS: Eligible patients (n = 206) were randomised to 8 weeks of mesalazine (4 g/day), either OD with two sachets of 2 g mesalazine granules in the morning (n = 102) or BD with one 2 g sachet in the morning and one in the evening (n = 104)...

Further on to our earlier work on the 4-oxo-1,4-dihydropyridine, we describe herein our strategy to get access to potent selective CB₂ receptor agonists. Thus, we designed and synthesized 29 compounds, evaluated on both hCB₁ and hCB₂ cannabinoid receptors, and assessed 11 of them in the TNBS-induced colitis model in mice. Compound 48 was found to be the most efficient of our series, exhibiting an exquisite protection against experimental colitis, superior to the one observed after treatment with Pentasa...

BACKGROUND AND AIM: Left-sided colitis is the most prevalent subtype of ulcerative colitis, a chronic inflammatory disease of the colon. The standard of care for mild-to-moderate ulcerative colitis is mesalazine. The PODIUM study compared a once daily to a twice daily dosing regimen of a slow-release mesalazine (Pentasa®); here we assess the efficacy, in terms of maintenance of remission and mucosal healing, of both regimens in patients with left-sided disease. PATIENTS AND METHODS: Eligible patients were randomised to once daily (1×2 g) or twice daily (2×1 g) oral treatment with mesalazine, for 12 months...

BACKGROUND: Patients receiving 5-aminosalicylic acid (5-ASA) require long-term therapy to achieve good outcomes. Persistency (duration of time from initiation to discontinuation of therapy) is therefore an important consideration. AIM: To evaluate persistency in patients receiving various oral 5-ASA formulations. METHODS: This retrospective, 12-month, cohort study examined new-starter patients (any age and diagnosis) from a large United States pharmacy database who filled a prescription for oral 5-ASA [Lialda(®), Asacol(®), Pentasa(®) 250 or 500 mg, balsalazide (generic and Colazal(®)), and olsalazine (Dipentum(®))] between March and September 2007...

BACKGROUND AND AIMS: Standard practice to maintain remission in ulcerative colitis (UC) consists of daily mesalazine therapy. However, frequent dosing is associated with poor adherence and increased failure rates. The PODIUM (Pentasa™ Once Daily In UC Maintenance) randomised control trial showed 2 g once daily (OD) to be superior to twice daily (BD) dosing for maintaining remission. We sought to determine whether this alternative dosing regimen is cost-effective. METHODS: An economic evaluation was conducted to compare costs and outcomes of OD with twice daily (BD) dosing...
