An overview of Balsalazide history; Balsalazide, a derivative of 5 aminosalicylic acids, is a significant advancement in gastroenterology. It emerged during the part of the 20th century to target and treat inflammatory bowel diseases, primarily ulcerative colitis, in a more localized manner. This drug provided an approach to traditional medications resulting in improved patient adherence and better treatment outcomes. Regarding classification, Balsalazide falls under the category of anti-inflammatory drugs and belongs explicitly to the aminosalicylates group. Its unique design ensures that its active components are released directly into the colon, enhancing its effectiveness while minimizing side effects.

Uses of Balsalazide

Balsalazide is primarily used for the treatment of colitis a condition characterized by inflammation and ulcers in the colon and rectum12Its primary purpose is to target the areas and alleviate symptoms like pain, diarrhea and bleeding13. Regarding how it works in diseases, Balsalazide remains relatively inactive until it reaches the colon after ingestion. Once it reaches the colon, the bacteria break it down to release 5-aminosalicylic acid, which directly combats inflammation in the colon24. This specific mechanism makes Balsalazide an effective treatment option now targeting the area.

How Balsalazide Works

The effectiveness of Balsalazide depends on its prodrug nature. In the colon, it goes through a biotransformation process where bacteria break it down to release five aminosalicylic acids. This acid works by inhibiting enzymes and mediators that play a role in the inflammatory process, thus exerting its anti-inflammatory effects. Apart from their localized actions, five aminosalicylic acids also impact the system. It specifically reduces the activity of cytokines, thereby creating an environment less prone to hyperactive inflammatory responses.

Dosage and Administration

The recommended dosage for conditions varies. In the case of colitis, a typical dosage of Balsalazide would be around 6.75 grams per day divided into three doses. However, doctors may adjust this regimen depending on the severity of the condition and how the patient responds to it. When taking Balsalazide, it is usually in form and meant to be taken orally. It's essential to take it with plenty of water and, if possible, with meals to ensure absorption. For patients with liver or kidney problems, dose adjustments might be necessary. Monitoring their condition and consulting with a healthcare professional in such cases is crucial.


The primary component of Balsalazide is the prodrug itself which undergoes metabolism to become five aminosalicylic acids. The other ingredients, such as binders, fillers, and colorants, may vary depending on the manufacturer. These additional components aid in drug delivery and enhance the appearance of the medication. Although capsules are commonly used, tablet formulations and extended-release versions are available in regions or from specific manufacturers. Introducing these forms aims to improve patient compliance with the prescribed treatment.


It is advised to store Balsalazide in a dry place, preferably at room temperature. Ensure that it is protected from sunlight and kept away from moisture. Before using the medication, always check the expiration date. If it has expired, discard it. If you have any doubts consult with a pharmacist.

During Balsalazide treatment, monitoring and assessing various aspects of the patient's health is essential. Regular checks on kidney function, liver enzymes, and blood counts are advisable to detect any abnormalities early. This monitoring is crucial as it can help prevent the worsening of side effects and ensure the treatment remains effective. While Balsalazide is generally well tolerated, there is a possibility of long-term consequences that patients should be aware of. These include kidney problems, complications related to the liver, and changes in blood cell counts. Patients need to have this awareness to participate in their healthcare decisions actively. Patients with existing conditions may require adjustments in their Balsalazide dosage due to how their bodies metabolize the medication. For example, dose modification may be necessary if a patient has renal dysfunction. Additionally, individuals with a history of the disease should receive closer monitoring due to possible respiratory effects. Continually monitoring and awareness are essential when using Balsalazide as part of a patient's treatment plan.

Administration Specifics

Administration to the Elderly

As people get older, their bodies may process drugs differently. This is mainly because the liver and kidneys might not function well as they used to. Because of this, doctors might need to adjust the dosage of Balsalazide by lowering it or increasing the time between doses. There are some things to consider when treating patients. They might be more prone to experiencing side effects like dizziness or digestive problems. Additionally, since elderly patients often take medications, there's a higher chance of these side effects being stronger or new interactions occurring.

Administration to Pregnant Women and Nursing Mothers
