1 What is Apriso?

Brand: Apriso, Asacol HD, Delzicol, Lialda

Generic: Mesalamine

Apriso is a non-steroidal anti-inflammatory drug which is generally used to treat and prevent ulcerative colitis (an inflammatory bowel disease). It is considered to be the active moiety of sulfasalazine.

The mechanism of action is uncertain, but may be due to its ability to inhibit local chemical mediators of the inflammatory response especially leukotriene synthesis in the gastrointestinal mucosa.

It works inside the intestine (bowel) to reduce inflammation and other symptoms of the disease. Also, this drug is often used in mild or moderate Crohn’s disease for treatment and prevention of flare-ups.

This medicine is available only with your doctor's prescription. This product is available in the following dosage forms:

  • Capsule, Delayed Release
  • Capsule, Extended Release
  • Tablet, Delayed Release

2 What to Know Before Using

Before using Apriso, you must know all about the risks and complications associated with it. The suitable drug therapy is usually chosen by a doctor with the active participation of the patient.

There are some important factors such as drug interactions, the presence of any metabolic impairment, history of hypersensitivity reaction, pregnancy, lactation etc. which may alter the desired therapeutic effects of a medicine.

Sometimes the presence of other health disorders affects the beneficial effects of this medicine and even may cause serious toxic effects. If you have had any allergic reactions to any medicine then you must tell your doctor about that.

The use of mesalamine is contraindicated in those who are hypersensitive to this drug or any of the ingredients of the formulation.

Make sure you inform your doctor if you have any other medical problems, especially:

  • Allergy to sulfasalazine (Azulfidine®)—May causes side effects to become worse.
  • Kidney disease—Use with caution. The effects may be increased because of slower removal of the medicine from the body.
  • Liver disease—Use with caution. May make this condition worse.
  • Phenylketonuria (PKU)—The Apriso™ capsule contains aspartame, which may require caution in patients with PKU.

Because of drug-drug interactions, certain medicines should not be used along with this medicine. It is always recommended to consult with your doctor if you are in need of some other medications or even any over-the-counter medicine for another health problem in order to avoid unwanted toxic effects.

It is advised not to use this medicine along with lactulose or other drugs which lower pH. Coated mesalamine may enhance the gastric toxicity of glucocorticoids and hypoglycemic action of sulfonylureas.

The following drug interactions should not be used concurrently:

  • Coumarins
  • Furosemide
  • Methotrexate
  • Mercaptopurine
  • Rifampicin
  • Spironolactone
  • Tamarind

Animal reproduction studies have not shown any adverse effect on the fetus and there are no adequate and well-controlled studies in humans. But animal reproduction studies are not always predictive of human response.

Thus, this drug should be used during pregnancy only if clearly needed. Besides, caution should be exercised when used in lactating women because there are no adequate studies in women for determining infant risk when using this medication during breastfeeding.
