Pentasa Extended Release and Mesalamine/5-aminosalicylic acid at CanadaPharmacyOnline.com

Ferring's Brand Pentasa Extended Release is available in many countries worldwide, including Canada, India, and Turkey.

The generic mesalamine/5-aminosalicylic acid is currently unavailable (at this pharmacy).

Dosage:

Pentasa Extended Release is offered in various strengths and forms:
• Oral Forms: 500 mg and 1000 mg extended-release capsules/tablets.
• Rectal Forms:
o 1 gram extended-release suppository.
o 1 and 4 gram extended-release enema, typically in 100 mL packaging.

Your doctor will determine the appropriate dosage based on your needs and medical conditions.

Usage:

Pentasa Extended Release (mesalamine/5-aminosalicylic acid) is a prescription medication for ulcerative colitis and Crohn's disease. Ulcerative colitis affects the colon and rectum, causing inflammation and redness in the lining of the gut. Crohn's disease is a form of inflammatory bowel disease (IBD) that primarily affects the intestines but may occur anywhere from the mouth to the anus. Pentasa is also used for the long-term treatment of ulcerative colitis and Crohn's disease to maintain remission and prevent relapse.

Mechanism of Action:
Pentasa Extended Release (mesalamine/5-aminosalicylic acid) is an anti-inflammatory drug that acts directly on the colon's lining to reduce swelling and irritation. Although its mechanism of action is not particular, it likely works by blocking specific pathways in the body that produce chemicals (such as prostaglandins and leukotrienes) that cause inflammation. Because the drug is extended-release, it helps make sure the medicine reaches all parts of the colon. Use Pentasa exactly as your doctor prescribes. Do not change your dosage or stop using the medication without consulting your doctor. Follow the instructions in the product monograph in Canada: https://pdf.hres.ca/dpd_pm/00077312.PDF. Consult your doctor for personalized guidance and safe use.
