Introduction

Salazopyrin 500 mg Enteric Tablets (Sulfasalazine) are widely prescribed for chronic inflammatory conditions of the bowel such as ulcerative colitis and Crohn’s disease, as well as autoimmune conditions such as rheumatoid arthritis. Manufactured by Pfizer, these tablets are formulated with an enteric coating that ensures the medicine reaches the intestines without dissolving in the stomach, reducing irritation and maximizing effectiveness.

This guide provides a comprehensive overview of Salazopyrin including its medical uses, dosage recommendations, mechanism of action, possible side effects, warnings, and reviews from patients who have used the product.

What is Salazopyrin?

Salazopyrin contains Sulfasalazine as the active ingredient. Sulfasalazine is a prodrug that breaks down in the colon into two components:

• 5-Aminosalicylic acid (5-ASA) → responsible for anti-inflammatory effects in the intestine.

• Sulfapyridine → absorbed systemically and contributes to immune modulation.

By reducing inflammation in the bowel lining and joints, Salazopyrin helps control symptoms such as abdominal pain, diarrhea, rectal bleeding, and joint stiffness.

Medical Uses of Salazopyrin 500 mg

Salazopyrin is primarily used to treat:

1. Ulcerative Colitis – to control flare-ups and maintain remission.

2. Crohn’s Disease – especially effective when inflammation is located in the colon.

3. Rheumatoid Arthritis (RA) – as a disease-modifying anti-rheumatic drug (DMARD).

4. Juvenile Arthritis – sometimes prescribed for children under specialist care.

Mechanism of Action

Once in the colon, intestinal bacteria split Sulfasalazine into 5-ASA and Sulfapyridine.

• 5-ASA reduces local inflammation in the gut by blocking prostaglandins and leukotrienes.

• Sulfapyridine contributes to systemic immunomodulatory effects, especially beneficial in rheumatoid arthritis.

Dosage and Administration

⚠️ Dosage must be determined by a physician. Typical regimens:

• Ulcerative Colitis (Adults): Start with 500 mg 2–4 times daily. The dose may be increased to 2–4 g/day depending on severity.

• Maintenance Therapy: Usually 1–2 g/day to prevent relapse.

• Rheumatoid Arthritis: Start with 500 mg once or twice daily, gradually increased to 2–3 g/day.

• Children (over 6 years): 30–50 mg/kg/day divided into doses.

Important tips:

• Take tablets after meals with a full glass of water.

• Do not crush or chew the tablets (enteric coating must remain intact).

• Continue regular blood tests as recommended by your doctor.
