5-aminosalicylic acid agents are effective in the treatment of ulcerative colitis. Balsalazide, mesalamine, and olsalazine are alternative formulations to sulfasalazine for the delivery of 5-aminosalicylic acid. The newer compounds might be better tolerated than sulfasalazine in some patients, as long
When less is not more but at least equivalent.

The electrochemical behavior of 2-hydroxy-5-[(4-sulfophenyl)azo]benzoic acid, 2-hydroxy-5-[(3-sulfophenyl)azo]benzoic acid and 2-hydroxy-5-[(2-sulfophenyl)-azo]benzoic acid was investigated by cyclic voltammetry using a glassy carbon electrode. The influence of the pH and position of the substituents on the reaction pathway has been studied. The results
