Aniline/Genotoxic Impurity Determination in Mesalamine Delayed Release Tablets by UPLC

New Dissolution Method for Mesalamine Tablets and Capsules

Dissolution methods are different for extended-release mesalamine capsules (pH 7.5 only) and delayed-release tablets (pH 1.4, 6.0, and 7.2). Mesalamine is used for the treatment of ulcerative colitis. The USP methods have several drawbacks in that they do not mimic gastrointestinal tract environments; tablets are removed from vessels to change dissolution medium; and neither method has been ado...

New Research in Ulcerative Colitis: Optimizing 5-ASA Administration for Efficacy and Adherence.

6 Gastroenterology & Hepatology Volume 6, Issue 1, Supplement 1 January 2010 Multiple daily dosing of 5-ASA for UC has been a standard practice since the 1940s. However, these regimens can lead to poor patient adherence. Recently, several 5-ASA formulations have demonstrated non-inferiority to multiple daily dosing, including ethylcellulose-coated microgranules (Pentasa),1 Multi-Matrix delayed ...

EFFECT OF LUMINAL pH CHANGES ON GUAR GUM-HPMC E15 LV MIXED MATRIX TABLETS FOR MESALAMINE DRUG DELIVERY TO COLON AND STUDY ON IN- VITRO CHARACTERISTICS IN TWO DIFFERENT DISSOLUTION MODELS vs. MARKETED FORMULATION

The study was designed to investigate the impact of colonic pH changes on formulated colon targeted Mesalamine matrix tablets in the treatment of inflammatory bowel disease (IBD). Mesalamine tablets were fabricated with guar gum as Polymer system. The different batches of Mesalamine tablets (GMM1GMM6) were compressed with increasing proportion of guar gum and HPMC E15 LV. The different buffer c...

Quality Evaluation of Traditional Chinese Medicine Compounds in Xiaoyan Lidan Tablets: Fingerprint and Quantitative Analysis Using UPLC-MS.

XiaoyanLidan tablets (XYLDTs) are traditional Chinese medicines frequently used for syndromes of the liver and gallbladder, cholecystitis and cholangitis. To evaluate the consistency of the quality of commercial XYLDT preparations, we established a simple and reliable ultra-performance liquid chromatography (UPLC) method with a photodiode array (PDA) detector and mass spectrometry (MS), includi...
