Crohn's disease is an autoimmune disorder that damages the digestive tract. Generally, this disease affects the small and large intestine regions of the digestive tract, resulting in ulcers or cracks in these regions. There is no defined treatment to cure the disease, but some steps may be taken to cure the symptoms. These steps are medication, surgery, and dietary recommendations.

Patients affected by Crohn’s disease encounter widening (flares) of the digestive tract lining along with an increase in inflammation (relapse) and a decrease in inflammation (remission) for a short time. This cycle continues for several months to years. During a relapse, the symptoms such as abdominal pain, diarrhea, rectal bleeding also increase.

What Are the Different Types of Medications Prescribed for the Treatment of Crohn's Disease?

The doctor prescribes a variety of medications for the treatment of Crohn's disease. These include:

Antibiotics: These drugs are given to patients who are suffering from bacterial infections and abscesses. Commonly prescribed antibiotics are ciprofloxacin and metronidazole.

Anti-Inflammatory Drugs: These drugs are given to patients who have an inflammation in the digestive track. They help in reducing the pain and symptoms of diarrhea. Some of the anti-inflammatory drugs are:

Corticosteroids: These drugs reduce the inflammation of digestive tract. They are usually given to patients with mild symptoms.

Aminosalicylates: These drugs are given to patients who have mild to moderate symptoms. They also help in the disease remission. Some of the commonly recommended aminosalicylates are Balsalazide, Mesalamine, Olsalazine, and Sulfasalazine.

Biologics:  These drugs reduce the inflammation by targeting the specific proteins involved in inflammation. They also help in can preventing the fistula if present in the digestive tract. Biologics are useful for treating the moderate to severe symptoms of the disease. They are given to patients other medications are not effective. Some of the examples of this class of drugs include Adalimumab, Adalimumab-atto, Certolizumab pegol, Infliximab, Natalizumab, and Vedolizumab.

Immunosuppressant Drugs: This class of drugs is responsible for reducing the activity of immune system against body’s own cells, and also help in remission. Immunosuppressant drugs are given to patients when other drugs are ineffective, or if there is any fistula within the digestive tract. Examples of immunosuppressant drugs are Azathioprine, Mercaptopurine, and Methotrexate.

Anti-Diarrheal Drugs: These drugs are prescribed when patients suffer from severe diarrhea.

  • People who are allergic to medications like corticosteroids, immunosuppressant drugs, etc.
  • Severe heart failure patients should not be recommended biologics >5mg/kg.
  • People with preexisting bone marrow and blood toxicity should not be given immunosuppressant drugs.
  • Alcoholics.

Should NSAIDs Recommended in Crohn's Disease?
