🌿 What is Naprosyn SR 750 mg?
Naprosyn SR 750 mg is an extended-release naproxen formulation. It delivers steady pain control over 24 hours. Hence, it minimizes dosing frequency. It remains effective for both chronic conditions, like osteoarthritis, and acute flare-ups, such as gout attacks.
🧬 How It Works
Naproxen inhibits cyclooxygenase (COX-1 and COX-2) enzymes. Therefore, it blocks prostaglandin production. As a result, pain signals reduce and inflammation subsides. Its sustained-release matrix ensures a gradual drug release, reducing peak-related side effects.
💡 Key Uses
- Chronic Arthritis: Daily symptom management in osteoarthritis and rheumatoid arthritis.
- Acute Pain: Relief from musculoskeletal injuries and gout flares.
- Inflammatory Disorders: Control of ankylosing spondylitis and bursitis.
💊 Dosage & Administration
| Condition | Dosage |
| Chronic Arthritis | 750 mg once daily (morning) |
| Acute Flare (e.g., Gout) | 1,500 mg on day one (750 mg twice daily), then 750 mg once daily |
Swallow whole; do not crush or chew. Take with food and a full glass of water to prevent stomach upset.
