PENTASA Tablets and Sachets NAME OF THE MEDICINE Mesalazine (5-ASA) Synonyms: 5-aminosalicylic acid 5-amino 2-hydroxybenzoic acid
PHARMACOLOGY Pharmacotherapeutic group: Intestinal anti-inflammatory agents (A07 EC02). Actions: It has been established that mesalazine is the active component of sulfasalazine, which is used for the treatment of ulcerative colitis and Crohn’s disease. Based on clinical results, the therapeutic value of mesalazine after oral as well as rectal administration appears to be due to a local effect ...
متن کاملElectrochemical Synthesis of 5-Aminosalicylic Acid from 5- Nitrosalicylic Acid in Alkaline Media
5-Aminosalicylic acid (5-ASA) is currently prepared by electrochemical reduction of 5-nitrosalicylic acid (5-NSA) in acidic media. In this work, electrolytic reduction of 5-NSA in alkaline media is presented. Reactionconditions and parameters such as anode and cathode electrodes, electrolyte type, reaction time, temperature,current, and the pH for isolation of product are investigated. The yiel...
متن کاملRelease of 5-Aminosalicylic Acid (5-ASA) from Mesalamine Formulations at Various pH Levels
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 Phar...
متن کاملNephrotoxic lesions from 5-aminosalicylic Acid.
5-Aminosalicylic acid given to rats as a single intravenous injection led to necrosis of the proximal convoluted tubules and of the renal papilla. These two lesions developed at the same time and the cortical lesions did not appear to be a consequence of the renal papillary necrosis. Since the compound possesses the molecular structure both of a phenacetin derivative and of a salicylate these o...
متن کاملControlled release of 5-aminosalicylic acid (5-ASA) from new biodegradable polyurethanes.
Segmented polyurethanes containing azo aromatic groups in the main chain were synthesized by reaction of 3,3'-azobis(6-hydroxybenzoic acid) (ABHB), 5-[4-(hydroxyphenyl)azo] salicylic acid (HPAS), and 5-[1-hydroxynaphthyl)azo] salicylic acid (HNAS) with hexamethylenediisocyanate (HDI). All synthesized monomers and polymers were characterized by elemental analysis, FTIR, 1H-NMR spectra, TGA and D...
