Pentasa Tablets 500mg (Mesalamine) | Used to Treat Ulcerative Colitis Flare-Ups, Proctitis, and Proctosigmoiditis
Pentasa Tablet contains Mesalamine, an anti-inflammatory medicine used to treat and manage ulcerative colitis and other inflammatory bowel diseases (IBD). It works by reducing inflammation in the colon and rectum, helping to relieve symptoms such as abdominal pain, diarrhea, and rectal bleeding.
Pentasa Tablet Product Overview
Pentasa is a premium aminosalicylate (5-ASA) medication containing Mesalamine, a potent anti-inflammatory specifically formulated for the gastrointestinal tract. It is a cornerstone therapy for managing Inflammatory Bowel Disease (IBD), including Ulcerative Colitis and Crohn’s Disease. Pentasa is unique for its prolonged-release mechanism, which ensures that the active medicine is distributed evenly throughout the small and large intestines. By reducing inflammation directly at the source, Pentasa helps patients achieve and maintain clinical remission, significantly improving their quality of life.

Mechanism of Action: How the Tablet Works
The clinical efficacy of Pentasa is derived from its localized and sustained anti-inflammatory action:
- Direct Mucosal Action: Unlike many systemic drugs, Mesalamine works topically on the lining of the gut to inhibit the production of inflammatory chemicals like prostaglandins and leukotrienes.
- Prolonged Release: Pentasa tablets consist of ethylcellulose-coated microgranules that release the medicine slowly. This allows the drug to reach the entire length of the intestine, from the duodenum to the rectum.
- Antioxidant Properties: It acts as a free radical scavenger, neutralizing reactive oxygen species that contribute to tissue damage during an IBD flare.
- Leukotriene Inhibition: By blocking the lipoxygenase pathway, it prevents the migration of white blood cells into the intestinal wall, reducing tissue swelling and ulceration.
- Remission Maintenance: Continuous use helps stabilize the gut lining, preventing the immune system from re-triggering the inflammatory cycle.
Key Benefits of Pentasa
- Targeted Gut Relief: Provides powerful anti-inflammatory action exactly where it is needed, with minimal absorption into the rest of the body.
- Dual IBD Coverage: One of the few aminosalicylates effective for both Ulcerative Colitis and Crohn’s Disease due to its wide distribution in the gut.
- Reduces Flare-Ups: Clinically proven to reduce the frequency of painful episodes, bloody stools, and urgent bowel movements.
- High Safety Profile: Generally well-tolerated for long-term use, making it a preferred choice for maintenance therapy.
- Improved Digestive Comfort: Helps resolve abdominal pain and cramping by healing the underlying intestinal inflammation.
- Sustained Delivery: The advanced granule technology ensures the medicine remains active throughout the digestive journey.

Pentasa Tablet Usage
To ensure the maximum clinical benefit of Pentasa Prolonged-Release Tablets and to maintain long-term digestive health, follow these administration guidelines:
Consistent Dosing: Take your Mesalamine tablets at the same time every day. Maintaining a steady level of the medication in your intestinal tract is essential for preventing inflammatory flares.
Administration Method: Swallow the tablets whole with a full glass of water. Do not crush or chew the tablets, as this destroys the specialized ethylcellulose coating on the microgranules, which is required for the medicine to reach the lower intestines.
Flexible Dosing: If you have difficulty swallowing, the tablets may be broken into smaller pieces or dissolved in a small amount of water or juice (approximately 50 ml) just before ingestion. Ensure you drink the entire mixture immediately.
Optimal Timing: Pentasa can be taken with or without food. However, taking it with a meal may help reduce the chance of mild stomach upset for some patients.
Hydration: It is important to stay well-hydrated while taking Pentasa 500 mg. Adequate water intake supports kidney function and assists the movement of the microgranules through the digestive system.
Treatment Continuity: Do not stop taking your medication even if you feel completely better. Pentasa is often prescribed as a maintenance therapy to keep the disease in remission and prevent future symptoms.
Missed Dose: If you forget a dose, take it as soon as you remember. If it is almost time for your next scheduled dose, skip the missed one. Never take a double dose to compensate.

Pentasa Tablet FAQs
Q: What is the primary function of Pentasa Tablets?
A: Pentasa is a specialized aminosalicylate (5-ASA) medication used to treat inflammatory bowel diseases (IBD). It contains Mesalamine, which works locally in the gut to reduce inflammation, swelling, and tissue damage in the intestinal lining.
Q: How does the "prolonged-release" feature of Pentasa work?
A: Pentasa tablets are formulated with coated microgranules that release the medicine slowly as they travel through the digestive tract. This ensures the medication reaches and treats inflammation in both the small intestine and the large intestine (colon).
Q: Can Pentasa cure Ulcerative Colitis or Crohn’s Disease?
A: While there is currently no permanent cure for IBD, Pentasa is highly effective at inducing and maintaining remission. Regular use helps keep the disease inactive, prevents painful "flares," and allows the intestinal lining to heal.
Q: What is the standard dosage for Pentasa 500 mg?
A: Dosage varies based on whether you are treating an active flare or maintaining remission. Typically, adults take 500 mg to 1000 mg several times a day as directed by a gastroenterologist. Always follow the specific schedule prescribed for your condition.
Q: Can I crush or chew Pentasa Tablets?
A: No, you should not crush or chew Pentasa Tablets. They are designed to be swallowed whole or, if necessary, broken into smaller pieces without crushing the internal granules. Chewing them destroys the prolonged-release coating, causing the medicine to release too early in the stomach.
Q: Is it normal to see tablet remains in the stool?
A: Occasionally, the outer shell or the empty microgranules may appear in your stool. This is usually normal and does not mean the medication didn't work; the active Mesalamine has likely already been absorbed into the intestinal lining.
Q: Are there any specific side effects to watch for?
A: Most patients tolerate Pentasa well. However, some may experience mild nausea, diarrhea, or abdominal pain. In rare cases, it can affect kidney function, so your doctor may request periodic blood and urine tests to monitor your health.
Q: How should I store my Pentasa medication?
A: Store Pentasa 500 mg tablets in a cool, dry place at room temperature (below 25°C). Keep them in their original blister pack to protect the microgranules from moisture and direct light.
