APRISO features the INTELLICOR® delayed- and extended-release delivery system and helps keep adult patients with ulcerative colitis (UC) in remission for up to 6 months.1

While the mechanism of action is unknown, mesalamine may decrease inflammation in the colon by blocking production of arachidonic acid metabolites.1

APRISO has been evaluated in two 6-month placebo-controlled trials, and for up to 24 months in an open-label extension study.1,2

APRISO is contraindicated in patients with hypersensitivity to salicylates, aminosalicylates, or any of the components in APRISO capsules.

Proven Efficacy

  • In clinical studies, ~7 of 10 patients in the intent-to-treat population maintained remission for up to 6 months with APRISO, compared with ~5.5 of 10 placebo patients1

Long-term Safety Profile

  • APRISO has a well-established safety profile from a 6‑month controlled, and a 24‑month open‑label, trial. The efficacy of APRISO for treating UC beyond 6 months has not been established1,2
  • Caution should be exercised when administering APRISO to patients with liver disease, known renal dysfunction or a history of renal disease
  • The most common adverse events (≥3%) of APRISO-treated patients were headache, diarrhea, abdominal pain upper, nausea, nasopharyngitis, influenza-like illness, and sinusitis

Once Daily

  • The recommended daily dosage is 4 APRISO 0.375-g capsules taken once daily (1.5 g/day) in the morning with or without food1


APRISO® (mesalamine) extended-release capsules are indicated for the maintenance of remission of ulcerative colitis (UC) in adults


  • APRISO extended-release capsules are contraindicated in patients with hypersensitivity to salicylates or aminosalicylates, or to any of the components of APRISO capsules.
  • Renal impairment, including minimal change nephropathy, acute and chronic interstitial nephritis, and, rarely, renal failure, has been reported in patients given products such as APRISO that contain mesalamine or are converted to mesalamine. It is recommended that patients have an evaluation of renal function prior to initiation of APRISO therapy and periodically while on therapy. Exercise caution when using APRISO in patients with known renal dysfunction or a history of renal disease.
  • Mesalamine has been associated with an acute intolerance syndrome that may be difficult to distinguish from a flare of inflammatory bowel disease. Symptoms include cramping, acute abdominal pain and bloody diarrhea, sometimes fever, headache, and rash. If acute intolerance syndrome is suspected, promptly discontinue treatment with APRISO.
  • There have been reports of hepatic failure in patients with pre-existing liver disease who have been administered mesalamine. Caution should be exercised when administering APRISO to patients with liver disease.
  • Patients with pre-existing skin conditions such as atopic dermatitis and atopic eczema have reported more severe photosensitivity reactions. Advise patients with pre-exiting skin conditions to avoid sun exposure, wear protective clothing, and use a broad spectrum sun screen outdoors.
  • Cases of nephrolithiasis have been reported with the use of mesalamine, Mesalamine-containing stones are radiotransparent and undetectable by standard radiography or computed tomography (CT). Ensure adequate fluid intake during treatment with APRISO.
  • In clinical studies, the most common adverse reactions (occurring in ≥3% of APRISO patients and at a greater rate than placebo) were headache (11%), diarrhea (8%), upper abdominal pain (5%), nausea (4%), nasopharyngitis (4%), influenza and influenza-like illness (4%), and sinusitis (3%).
  • Because dissolution of the coating of APRISO granules depends on pH, APRISO should not be co-administered with antacids.
  • Because of the potential for blood dyscrasias in patients 65 years and older, caution should be taken to closely monitor blood cell counts during mesalamine therapy in these patients.
  • Inform patients with phenylketonuria (PKU) or their caregivers that each APRISO capsule contains aspartame equivalent to 0.56 mg of phenylalanine, so that the recommended adult dosing provides an equivalent of 2.24 mg of phenylalanine per day.
