About Pentasa
Pentasa is a brand-name formulation of mesalamine, an oral 5-aminosalicylic acid (5-ASA) approved in Singapore for the maintenance and treatment of ulcerative colitis. It belongs to the class of aminosalicylates, agents that target inflammation in the lining of the colon. By delivering mesalamine directly to the intestinal mucosa, Pentasa helps control flare-ups, supports remission, and reduces the need for corticosteroids. Patients who have been diagnosed with ulcerative colitis often turn to this therapy when topical options such as suppositories or enemas are insufficient, and the once-daily 400 mg pill fits conveniently into a regular routine.
What is Pentasa?
Pentasa is a mesalamine-based oral medication marketed under a proprietary brand name. In Singapore, it is regulated as a prescription product by the Health Sciences Authority (HSA) and is indicated for the induction of remission, as well as the maintenance of remission, in patients with mild-to-moderate ulcerative colitis. The formulation uses a pH-dependent coating that releases mesalamine throughout the small intestine and colon, ensuring a more uniform distribution compared with some time-release products. Because the active ingredient is the same as in generic mesalamine tablets, clinical efficacy and safety are comparable, while the branded delivery system aims to improve tolerability.
How Pentasa Works
Mesalamine exerts its anti-inflammatory effect primarily by inhibiting the cyclooxygenase (COX) and lipoxygenase pathways, which reduces the production of prostaglandins and leukotrienes-key mediators of intestinal inflammation. It also blocks nuclear factor-κB (NF-κB) activation, lowering cytokine release such as interleukin-1 and tumor necrosis factor-α. The pH-dependent coating of Pentasa dissolves at a pH of about 6-7, allowing the drug to reach the distal small intestine and colon before it is absorbed. This targeted release maximises local therapeutic concentrations while limiting systemic exposure, which translates into rapid symptom relief (often within 2-3 weeks) and sustained remission for many patients.
Why Pentasa is Used for Digestive Care, Inflammation Conditions
- Ulcerative colitis (induction of remission): By delivering mesalamine directly to inflamed colonic tissue, Pentasa suppresses the inflammatory cascade early in the disease course, frequently avoiding the need for systemic steroids.
- Ulcerative colitis (maintenance therapy): Continuous low-grade anti-inflammatory activity helps keep the mucosa quiescent, reducing the frequency of flare-ups and hospitalisations.
- Pouchitis after ileal-pouch-anal anastomosis: Studies show mesalamine can improve pouch inflammation, and Pentasa’s extended release provides consistent drug levels throughout the pouch.
- Crohn’s disease limited to the colon (off-label): Though not approved, some clinicians use mesalamine for colonic Crohn’s because the drug’s local action mirrors that in ulcerative colitis.
In each case, Pentasa’s mechanism aligns with the pathophysiology of mucosal inflammation, making it a first-line option in most Singaporean treatment guidelines. Compared with other oral 5-ASA products, its pH-dependent coating may offer better tolerability for patients who experience nausea with time-release tablets.
Off-Label and Investigational Uses of Pentasa
Evidence from small-scale randomized trials and cohort studies suggests mesalamine may have modest benefit in treating microscopic colitis and in preventing post-operative recurrence of Crohn’s disease affecting the colon. These uses are not approved by the HSA, and clinicians should consider them only under specialist supervision. Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Pentasa Right for You?
Pentasa is generally appropriate for adults who have confirmed mild-to-moderate ulcerative colitis and who can adhere to a daily oral regimen. It is less suitable for patients with severe disease requiring rapid immunosuppression, for those with a known hypersensitivity to mesalamine, or for individuals with significant renal impairment where dosage adjustment may be needed. Pregnant or breastfeeding women should discuss risks with their obstetrician, as data are limited but no teratogenic signal has emerged. Elderly patients often tolerate Pentasa well, yet dose reductions are prudent if creatinine clearance falls below 30 mL/min.
Taking Pentasa Effectively
- Timing: Take the 400 mg pill with water, preferably at the same time each day to maintain steady drug levels.
- Food interactions: Food does not significantly affect absorption; the coating dissolves in the intestinal lumen regardless of meals.
- Missed dose: If a dose is missed within 12 hours, take it as soon as remembered. If more than 12 hours have passed, skip the missed tablet and resume the regular schedule-do not double-dose.
- Travel: Bring a sufficient supply for the entire trip, as obtaining a prescription abroad may be challenging. Store the tablets at room temperature, away from moisture.
- Lifestyle integration: Combine medication adherence with a low-residue diet during flare-ups, adequate hydration, and regular exercise to support overall gut health.
Understanding Side Effects and How to Manage Them
Common adverse events such as nausea, abdominal cramping, headache, and flatulence stem from mesalamine’s direct contact with the gastrointestinal mucosa. Taking the tablet with a small snack or dividing the daily dose (if clinically appropriate) can ease stomach discomfort. Rare but serious reactions-manifesting as severe rash, liver enzyme elevation, or interstitial nephritis-reflect systemic immune activation or hypersensitivity. Patients should seek immediate medical attention if they notice swelling, jaundice, dark urine, or persistent fever.

Frequently Asked Questions
-
What makes Pentasa different from other mesalamine tablets? Pentasa uses a pH-dependent coating that releases mesalamine throughout the small intestine and colon, providing a more uniform distribution compared with time-release pellets that dissolve later in the gut.
-
Can I take Pentasa with other ulcerative colitis medicines? Yes, clinicians often combine Pentasa with topical therapies (suppositories or enemas) during severe flare-ups, but any combination should be approved by your gastroenterologist.
-
Is it safe to use Pentasa while on anticoagulants? Mesalamine has a low risk of affecting coagulation, yet rare cases of platelet dysfunction have been reported. Discuss any anticoagulant therapy with your doctor before starting Pentasa.
-
How quickly will I feel relief after starting Pentasa? Many patients notice a reduction in diarrhea and abdominal pain within 2-3 weeks, though full mucosal healing may require 8-12 weeks of consistent therapy.
-
Will my insurance cover Pentasa? Coverage varies between private insurers in Singapore. Some plans list mesalamine under specialist-prescribed medicines; others may require prior authorization.
-
Can I switch from a generic mesalamine to Pentasa? Because the active ingredient is identical, a switch is clinically acceptable. However, the branded coating may improve tolerability for patients who experienced nausea with generic formulations.
-
What should I do if I forget to take a dose for several days? Contact your prescriber promptly. Restarting after a prolonged gap may require dose reassessment to avoid sub-therapeutic exposure.
-
Is Pentasa appropriate for pediatric patients? Pentasa is approved for adults only in Singapore. Pediatric ulcerative colitis is typically managed with age-adjusted doses of other 5-ASA formulations under specialist care.
-
Does Pentasa interact with vitamins or supplements? No clinically significant interactions have been identified, but high-dose iron supplements can cause gastrointestinal irritation that might amplify mesalamine-related discomfort.
-
Can I store Pentasa in the bathroom cabinet? Store the tablets at room temperature, away from excess moisture and direct sunlight; a bathroom cabinet can become humid, so a kitchen drawer or closet is preferable.
