Balsalazide

Ulcerative Colitis Treatment

Balsalazide is primarily used to treat the symptoms of mildly to moderately active ulcerative colitis. This is a chronic inflammatory bowel disease that causes swelling and sores in the lining of the colon and rectum.

The medication is approved for use in the following populations:

• Adults
• Children 5 years of age and older

Symptom Management

By reducing inflammation directly in the large intestine, balsalazide helps alleviate common symptoms associated with active flare-ups, including:

• Diarrhea
• Rectal bleeding
• Stomach pain or cramping

The medication works locally in the colon to address the underlying inflammation that causes these symptoms during the active phase of the disease.

Mechanism of Action

Balsalazide belongs to a class of medications called aminosalicylates. It is used to treat the symptoms of ulcerative colitis by targeting inflammation in the colon.

The medication is considered a prodrug, which means it is inactive when first swallowed and must be converted into its active form inside the body. The process works as follows:

• Targeted Delivery: After the medication is swallowed, it passes through the stomach and small intestine mostly intact and is not absorbed into the bloodstream.
• Activation in the Colon: When the drug reaches the large intestine (colon), it is broken down by naturally occurring bacteria. This process releases the active component of the medicine, known as mesalamine or 5-aminosalicylic acid (5-ASA).
• Local Anti-inflammatory Effect: The released mesalamine works directly on the lining of the colon. It helps reduce the production of certain chemicals that cause inflammation, swelling, and tissue damage.

By decreasing inflammation locally in the colon, balsalazide helps relieve symptoms such as stomach pain, diarrhea, and rectal bleeding, and helps the intestinal lining to heal.

Common Side Effects

Some people may experience mild side effects while taking balsalazide. These often include:

• Headache
• Nausea or vomiting
• Stomach pain or diarrhea
• Joint or muscle pain
• Fatigue or tiredness
• Cold symptoms, such as a runny nose or sore throat
• Difficulty sleeping

Serious Side Effects

While less common, some side effects can be serious. Contact a healthcare provider immediately if you experience:

• Worsening of ulcerative colitis symptoms, such as increased stomach pain, cramping, fever, or bloody diarrhea
• Signs of kidney problems, including decreased urination or swelling in the legs and feet
• Signs of liver problems, such as yellowing of the eyes or skin, dark urine, or loss of appetite
• Chest pain or difficulty breathing

Seek emergency medical care if you develop signs of a severe allergic reaction, including a skin rash, hives, or swelling of the face, lips, or throat.

Allergic Reactions

Balsalazide is contraindicated in individuals with a known hypersensitivity to salicylates, such as aspirin, or any of the components in the medication. Severe skin reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis, have been reported. Treatment should be stopped at the first sign of a skin rash or other hypersensitivity symptoms.

Kidney and Liver Health

Kidney impairment, including cases of renal failure, has been associated with medications containing mesalamine (the active metabolite of balsalazide). It is recommended that kidney function be evaluated before starting treatment and periodically during therapy. Caution is also advised for individuals with known liver disease, as there have been reports of liver failure in patients using similar medications.

Acute Intolerance Syndrome

Some patients may experience an acute intolerance syndrome that can be difficult to distinguish from a flare-up of ulcerative colitis. Symptoms may include:

• Abdominal pain and cramping
• Bloody diarrhea
• Fever
• Headache
• Rash

If these symptoms occur, the medication should be discontinued immediately.

Other Precautions

Gastrointestinal Obstruction

Individuals with pyloric stenosis or other types of upper gastrointestinal obstruction may experience a delay in the release of the medication into the colon.

Photosensitivity

Patients with pre-existing skin conditions, such as atopic dermatitis or eczema, may experience more severe photosensitivity reactions while taking this medication. Protective clothing and sunscreen are recommended when exposed to sunlight.

Pregnancy

There is limited research on the effects of balsalazide in pregnant women. While animal studies have generally not shown evidence of harm to the developing fetus, human data is insufficient to confirm safety. For this reason, healthcare providers usually recommend using this medication during pregnancy only when the potential benefits clearly outweigh the potential risks.

Breastfeeding

It is currently unknown if balsalazide or its metabolites are excreted in human breast milk. Because many medications can pass into milk and potentially affect a nursing infant, caution is advised. Individuals who are breastfeeding should discuss the risks and benefits with their healthcare provider before using this medication.

Available Forms

Balsalazide is available for oral administration in the following forms:

• Capsules: These are taken by mouth. Depending on the specific product and patient needs, the capsules may be swallowed whole or opened and the contents sprinkled onto soft food.
• Tablets: These are oral tablets that are intended to be swallowed whole.

FDA Approval Status

Balsalazide disodium received its initial approval from the U.S. Food and Drug Administration (FDA) in 2000. It is classified as an aminosalicylate. The medication is specifically indicated for the treatment of mildly to moderately active ulcerative colitis in patients 5 years of age and older.

Regulatory Requirements

There are no boxed warnings or Risk Evaluation and Mitigation Strategies (REMS) associated with balsalazide. The FDA maintains oversight of the drug through standard post-marketing safety surveillance. Labeling requirements include precautions for patients with renal impairment, as cases of renal toxicity have been reported with products containing or converted to mesalamine.

Safety Designations

Balsalazide is included in the FDA's Liver Toxicity Knowledge Base (LTKB) as part of ongoing research into drug-induced liver injury, though it is generally considered to have a low potential for severe hepatotoxicity compared to many other therapeutic classes. Regulatory documentation also notes that patients with pyloric stenosis should be monitored, as they may experience prolonged retention of the medication in the stomach.

Generic vs. Brand Name

Balsalazide is available as a generic drug, which typically costs less than brand-name versions. Opting for the generic version is a common way to reduce the total cost of treatment for ulcerative colitis.

Insurance and Pharmacy Factors

• Insurance Coverage: Most insurance plans cover balsalazide, but the out-of-pocket cost depends on the plan's formulary and tier system.
• Pharmacy Pricing: Prices can vary between different retail pharmacies. Using mail-order pharmacies provided by insurance companies may sometimes offer a lower cost for a 90-day supply.

Ways to Save

Patients may be able to reduce costs by using prescription discount cards or manufacturer coupons when available. It is recommended to compare prices at local pharmacies and discuss lower-cost alternatives with a healthcare provider or pharmacist if the medication is not affordable.
