What dose of 5-aminosalicylic acid (mesalazine) in ulcerative colitis?

Sulphasalazine was developed in the 1930s, initially for use in patients with rheumatic polyarthritis. However, its modest eVects in arthritis were soon overshadowed by the striking benefits seen when the drug was given to patients with active colitis. Controlled clinical trials confirmed the early favourable impressions and established a role for sulphasalazine in the treatment of active disea...

Synthesis and evaluation of a prodrug of 5-aminosalicylic acid for the treatment of ulcerative colitis

Objective(s): This study is aimed to design and synthesize a prodrug of 5-aminosalicylic acid and evaluate its ameliorative effect on experimental ulcerative colitis (UC).Materials and Methods: 5-Aminosalicylic acid-alanine (5-ASA-ALA) was synthesized and characterized. Its stability study was conducted in rat plasma and in the gastroint...

Medication use patterns and predictors of nonpersistence and nonadherence with oral 5-aminosalicylic acid therapy in patients with ulcerative colitis.

BACKGROUND 5-aminosalicylic acid (5-ASA) is the recommended first-line treatment for active mild-to-moderate ulcerative colitis (UC) and for maintenance of UC remission. However, persistence and adherence to prescribed 5-ASAs are often suboptimal. OBJECTIVE To evaluate 5-ASA medication use patterns and assess risk factors associated with nonpersistence and nonadherence to oral 5-ASA medicatio...

Comparison of delayed release 5 aminosalicylic acid (mesalazine) and sulphasalazine in the treatment of mild to moderate ulcerative colitis relapse.

Oral formulations of 5-aminosalicylic acid (mesalazine) appear less toxic than sulphasalazine. We have therefore compared sulphasalazine, low dose mesalazine and high dose mesalazine in the treatment of mild to moderate relapse of ulcerative colitis. Sixty one patients (32 men, aged 20-78 years) were randomly allocated to sulphasalazine 2 g daily, mesalazine 800 mg daily, or mesalazine 2.4 g da...
