Each Asacol delayed-release tablet for oral administration contains 400 mg of mesalamine, an anti-inflammatory drug. The Asacol delayed-release tablets are coated with acrylic based resin, Eudragit S (methacrylic acid copolymer B, NF), which dissolves at pH 7 or greater, releasing mesalamine in the terminal ileum and beyond for topical anti-inflammatory action in the colon.
Asacol tablets are indicated for the treatment of mildly to moderately active ulcerative colitis and for the maintenance of remission of ulcerative colitis.
Published Studies Related to Asacol (Mesalamine)
Randomised clinical trial: evaluation of the efficacy of mesalazine (mesalamine)
suppositories in patients with ulcerative colitis and active rectal inflammation
-- a placebo-controlled study. 
categorised by the extent of lesions... CONCLUSIONS: The effectiveness of mesalazine suppositories in all types of UC
Budesonide 9 mg is at least as effective as mesalamine 4.5 g in patients with mildly to moderately active Crohn's disease. [2011.02]
BACKGROUND & AIMS: Comparative data on budesonide vs mesalamine for the treatment of mild-to-moderately active Crohn's disease (CD) are sparse. We assessed the efficacy and safety of each therapy in patients with mildly to moderately active CD... CONCLUSIONS: Budesonide (9 mg/day) was numerically, but not statistically, more effective than Eudragit-L-coated mesalamine (4.5 g/day) in patients with mildly to moderately active CD. Budesonide (9 mg/day), administered once daily, was as effective as the standard (3 times daily) regimen. Copyright (c) 2011 AGA Institute. Published by Elsevier Inc. All rights reserved.
A multicenter, randomized study to evaluate the efficacy and safety of mesalamine suppositories 1 g at bedtime and 500 mg Twice daily in patients with active mild-to-moderate ulcerative proctitis. [2011.02]
BACKGROUND: Ulcerative proctitis (UP) is a prevalent condition associated with increased morbidity and mortality. Topical mesalamine (5-aminosalicylic acid [5-ASA]) inhibits inflammatory processes in UP... CONCLUSIONS: Mesalamine 500-mg BID and 1-g QHS suppositories are safe and effective for patients with UP. Most patients reported significant improvement within 3 weeks and UP remission and reduced disease extension after 6 weeks of treatment. Validity of QHS administration was confirmed.
Clinical trial: a novel high-dose 1 g mesalamine suppository (Salofalk) once daily is as efficacious as a 500-mg suppository thrice daily in active ulcerative proctitis. [2010.11]
BACKGROUND: Mesalamine suppositories are first-line therapy in active ulcerative proctitis; the standard regime still recommends multiple doses per day. The primary objective of this study was to show the noninferiority of once-daily administration of a novel 1 g mesalamine suppository versus thrice-daily administration of the 0.5 g mesalamine suppository... CONCLUSIONS: In active ulcerative proctitis the once-daily administration of a 1 g mesalamine suppository is as effective and safe, yet considerably more convenient, than the standard thrice-daily administration of a 0.5 g mesalamine suppository.
Clinical trial: once-daily mesalamine granules for maintenance of remission of ulcerative colitis - a 6-month placebo-controlled trial. [2010.10]
BACKGROUND: Ulcerative colitis (UC) is a chronic relapsing and remitting idiopathic inflammatory bowel disorder. AIM: To evaluate once-daily mesalamine (mesalazine) granules (MG) for maintenance of remission of UC... CONCLUSIONS: Once-daily mesalamine (mesalazine) was effective in maintaining remission of UC for 6 months. (c) 2010 Salix Pharmaceuticals.
Clinical Trials Related to Asacol (Mesalamine)
Safety and Efficacy of Asacol 4.8 g/Day Versus Asacol 2.4 g/Day (ASCEND I) [Completed]
Assessing the Safety/Efficacy of Asacol® Given Every 12 Hours to Children and Adolescents for the Maintenance of Remission of Ulcerative Colitis [Recruiting]
The purpose of this study is to determine whether low dose Asacol® (27 mg/kg - 71 mg/kg) and
high dose Asacol® (53 mg/kg - 118 mg/kg) are safe and effective when dosed as 400 mg
delayed-release tablets given twice daily for 26 weeks to children and adolescents for the
maintenance of remission of ulcerative colitis.
Once Daily Versus Conventional Dosing of Asacol in the Maintenance of Quiescent Ulcerative Colitis [Terminated]
The purpose of this study is to determine if taking Asacol once a day is as effective as
taking Asacol twice or three times a day in keeping ulcerative colitis inactive, and to
determine which dosing regimen is easiest to follow. Once daily dosing of Asacol is
experimental, and has not been approved by the FDA. Dosing as three times daily is FDA
This research is being done because the researchers want to learn what the best methods are
for keeping ulcerative colitis inactive, and which way of taking Asacol is most helpful to
subjects in continuing to take a medication to control their ulcerative colitis.

after 8 weeks of treatment with SPD476, 2. 4 g/day once daily vs placebo and SPD476 4. 8 g/day
once daily versus placebo

Asacol review by care giver of 15 year old male patient
|Overall rating:|| || |
|Effectiveness:|| || Ineffective|
|Side effects:|| || Extremely Severe Side Effects|
|Condition / reason:|| || Ulcerative Colitis|
|Dosage & duration:|| || 800 mg taken bid for the period of 2 weeks|
|Other conditions:|| || None|

|Benefits:|| || There were no benefits as he had to stop taking it|
|Side effects:|| || Brownish colored urine, nausea and vomiting, stomache ache|
|Comments:|| || Patient was to take 800 mg twice daily to treat ulcerative colitis but was found to be intolerant to Asacol and was discontinued. The side effects began about 7-10 days after starting the Asacol. The nausea and vomiting was not immediately associated with Asacol but was attributed to possibly having the flu. It was only until his urine became a brownish purple color that we thought it must be the Asacol and immediately stopped it. Symptoms went away when stopped.|
