Medication for ulcerative colitis
Drugs that dampen and contain inflammation are an important pillar in the treatment of ulcerative colitis. The following anti-inflammatory medications, for example, are used during an acute attack:
- Aminosalicylates: Active substances from this group reduce inflammation in the intestine. Doctors mainly use the active ingredient mesalazine. The medication is also suitable for long-term treatment. Mesalazine prevents new relapses or reduces their frequency. The medicines are available in various dosage forms: as tablets, suppositories or foam and enemas for the rectum if the inflammation is located there. Possible side effects include headaches. However, mesalazine is generally very well tolerated and has few side effects. It does not inhibit the immune system
- Probiotics: These contain health-promoting bacteria and can be an alternative to mesalazine – for example, if you cannot tolerate the active ingredient. The bacteria can prevent a further flare-up. Probiotics containing E. coli bacteria of the Nissle 1917 strain are recommended.
- Corticosteroids (“cortisone”): These are immunosuppressants that suppress the immune system. Doctors use it in acute flare-ups when aminosalicylates such as mesalazine have not shown sufficient success. However, drugs containing cortisone are not suitable for long-term treatment of ulcerative colitis due to the side effects. Prednisolone in tablet form is a commonly used active ingredient. Cortisone can also be administered as an infusion in higher doses. Cortisone can lead to sleep disorders, weight gain, acne and an increase in blood sugar. If taken over a longer period of time, it also causes bone loss (“osteoporosis”). Continuous administration of more than 10 mg for more than two months should be avoided if possible.
- Budenoside is a cortisone-like medication that only works in the intestine because it is broken down very quickly by the liver. Despite having a comparable effect to normal cortisone, it therefore has significantly fewer side effects. The medication is available as tablets, enemas, foam or suppositories – it acts directly at the site of inflammation.
- Immunosuppressants of the “thiopurine type”: These are used when mesalazine and cortisone have not produced a sufficient effect. Examples of these active substances are azathioprine and 6-mercaptopurine. These immunosuppressants are not suitable for treating an acute attack of ulcerative colitis, but are suitable for maintaining freedom from symptoms, i.e. for long-term therapy. However, it takes a few months for the medication to take effect. So you need to be a little patient. Possible side effects: Headache, dizziness, inflammation of the liver and pancreas.
- Ciclosporin, methotrexate and tacrolimus are sometimes an option for very severe attacks of ulcerative colitis. It also takes a few months for them to take effect.
- Antibodies (biologicals): These drugs intervene in the inflammatory metabolism and influence the immune system. Active substances for the treatment of ulcerative colitis include (in order of approval) infliximab, adalimumab or golimumab, vedolizumab and ustekinumab. The medication is available as an injection or infusion. They either block inflammatory messengers or, like vedolizumab, prevent inflammatory cells from migrating into the intestine. The time to onset of action varies for the biologics. Infliximab has the fastest effect. Vedolizumab has the slowest effect. However, vedolizumab only works in the intestine and cannot weaken the immune functions in other organs.
Please note the following: Medications that affect the immune system increase susceptibility to infections. Bacteria, viruses or fungi can therefore trigger infections more easily. This increased susceptibility to infections can be a problem, especially for older people or those with other underlying illnesses. Always discuss the benefits and risks of all medications in detail with your doctor.
