- Refer to CKS and ECCO for further information on the prescribing of aminosalicylates in ulcerative colitis and Crohn’s disease
- Drugs used to maintain or induce remission in inflammatory bowel disease should always be started by a specialist, but they may be continued and monitored by a GP in primary care as per shared care arrangements.
- For acute attacks, prescribers may consider titrating doses according to response whilst awaiting specialist admission.
- Maintenance rectal therapy is an appropriate treatment strategy for rectal disease. Suppositories are the treatment of choice for patients with inflammation confined to the rectum; enemas should be used for more extensive inflammation.
- Foam and liquid appear to be equally effective in treating patients with distal ulcerative colitis. Foam enemas are generally preferred because they are easier to administer and retention is more comfortable. However, liquid enemas are more effective for proximal disease as they travel further. Suppositories are usually better tolerated than enemas.
- Mesalazine enemas are likely to be more effective than steroid enemas. Steroid enemas should be reserved for those patients who do not respond to mesalazine. Please note prednisolone foam enemas are very high cost. Predsol® retention enema 20mg/100ml rectal solution is a cost effective option. If a steroid foam is required, Budenofalk® (budesonide) rectal foam is less expensive than prednisolone foam.
- There is no evidence to show that any one oral preparation of mesalazine is more effective than another; however, the delivery characteristics of oral mesalazine preparations may vary. If it is necessary to switch a patient to a different brand of mesalazine the patient should be advised to report any changes in symptoms.
- Patient tolerability can vary between mesalazine products therefore it is worth trying a few different products – see BNF for full range of products.
- Acute exacerbation of extensive disease requires systemic corticosteroid.
