Additional Information
| Product | Description |
|---|---|
| NAPROSYN Tablets | Yellow, capsule-shaped oral tablets containing 500 mg of naproxen. |

Drug Interactions
Naprosyn Tablets, EC-Naprosyn, and Anaprox DS can potentially interact with various other medications, which may lead to serious adverse effects or diminished efficacy of one or both of the medications.
- **Anticoagulants**: Concomitant use with anticoagulants like warfarin increases the risk of serious bleeding.
- **SSRIs and SNRIs**: Use with selective serotonin reuptake inhibitors (SSRIs) and serotonin norepinephrine reuptake inhibitors (SNRIs) can increase the risk of bleeding due to their effect on platelet aggregation.
- **Aspirin**: Naproxen can interfere with the antiplatelet effect of low-dose aspirin, potentially reducing its efficacy in preventing cardiovascular events.
- **ACE Inhibitors and ARBs**: NSAIDs may reduce the antihypertensive effect of ACE inhibitors, angiotensin receptor blockers, and beta-blockers.
- **Diuretics**: Post-marketing observations indicate that NSAIDs can reduce the natriuretic effect of loop diuretics and thiazides, which may lead to worsening renal function.
- **Lithium**: Naproxen may increase plasma lithium levels by reducing renal lithium clearance, potentially leading to toxicity.
- **Methotrexate**: Concomitant use may increase the risk of methotrexate toxicity due to decreased renal clearance.
- **Cyclosporine**: Co-administration can increase the nephrotoxicity of cyclosporine.
- **Other NSAIDs and Salicylates**: Increased risk of gastrointestinal toxicity with little or no increase in efficacy.
- **Pemetrexed**: Increased risk of myelosuppression, renal, and gastrointestinal toxicity, particularly in patients with moderate renal impairment.
| Drug | Interaction Type | Clinical Impact | Intervention |
|---|---|---|---|
| Anticoagulants | Increased risk of bleeding | Synergistic effect on bleeding | Monitor for signs of bleeding |
| Aspirin | Interference with antiplatelet activity | Reduced efficacy in cardiovascular protection | Consider alternate analgesics |
| ACE Inhibitors and ARBs | Reduced antihypertensive effect | Diminished blood pressure control | Monitor blood pressure |
| Diuretics | Reduced natriuretic effect | Worsening renal function | Monitor for renal function |
| Lithium | Increased plasma lithium levels | Lithium toxicity | Monitor lithium levels |
| Methotrexate | Increased methotrexate toxicity | Higher risk of neutropenia and thrombocytopenia | Monitor for toxicity |
| Cyclosporine | Increased nephrotoxicity | Worsened renal function | Monitor renal function |
| Other NSAIDs | Increased GI toxicity | Greater risk of GI adverse events | Avoid concomitant use |
Management of Pain, Dysmenorrhea, and Tendonitis
Naprosyn Tablets, EC-Naprosyn, and Anaprox DS have specific dosing protocols for managing pain, primary dysmenorrhea, and acute tendonitis and bursitis.
**For pain management and dysmenorrhea**:
- **Starting dose**: 550 mg of Anaprox DS followed by 550 mg every 12 hours or 275 mg every 6-8 hours as required.
- **Maximum initial daily dose**: Should not exceed 1375 mg of naproxen sodium.
- **Subsequent daily dose**: Should not exceed 1100 mg of naproxen sodium.
**For acute tendonitis and bursitis**:
- **Starting dose**: 500 mg of Naprosyn followed by 250 mg every 6-8 hours as required.
- **Total daily dose**: Should not exceed 1250 mg of naproxen.
Naproxen sodium, available in Anaprox DS, is more rapidly absorbed, making it suitable for conditions requiring prompt onset of pain relief. EC-Naprosyn is not recommended for initial treatment of acute pain due to delayed absorption.
Polyarticular Juvenile Idiopathic Arthritis
In pediatric patients, naproxen solid-oral dosage forms may not allow for flexible dosing. A liquid formulation is recommended for weight-based dosing. The total daily dose of naproxen is approximately 10 mg/kg given in divided doses.
Dosage Recommendations for Specific Conditions
The recommended dosages for managing rheumatoid arthritis, osteoarthritis, and ankylosing spondylitis vary based on the specific product:
| Condition | Product | Dosage |
|---|---|---|
| Rheumatoid Arthritis, Osteoarthritis, Ankylosing Spondylitis | NAPROSYN Tablets | 500 mg twice daily |
| ANAPROX DS | 550 mg twice daily | |
| EC-NAPROSYN | 375 mg or 500 mg twice daily |
In long-term administration, the naproxen dose may be adjusted depending on the clinical response. Typical cases allow for reducing the total daily dose if appropriate and increasing it up to 1500 mg per day for limited periods when necessary.
Use in Pediatric Patients
Safety and efficacy in pediatric patients below the age of 2 years have not been established. For those aged 2 years and older, appropriate single doses range from 2.5 to 5 mg/kg as naproxen suspension, with a total daily dose not surpassing 15 mg/kg/day.
Storage and Handling
| Product | Formulation | Storage Conditions | Packaging |
|---|---|---|---|
| NAPROSYN Tablets | 500 mg | 15°C to 30°C (59°F to 86°F) | Bottles of 100 |
| EC-NAPROSYN | 375 mg and 500 mg | 15°C to 30°C (59°F to 86°F) | Bottles of 100 |
| ANAPROX DS | 550 mg | 15°C to 30°C (59°F to 86°F) | Bottles of 100 |
Clinical Pharmacology
The mechanism of action for naproxen involves the inhibition of cyclooxygenase (COX-1 and COX-2), which reduces the synthesis of prostaglandins—mediators of inflammation and pain. ANAPROX DS (naproxen sodium) provides rapid pain relief due to its high absorption rate.
Pharmacokinetics studies show that naproxen is rapidly and completely absorbed with an in-vivo bioavailability of 95%. The elimination half-life ranges from 12 to 17 hours, and steady-state levels are reached within 4 to 5 days.
Special Populations
**Pediatric Patients**: Plasma levels following a 5 mg/kg single dose of naproxen suspension in children aged 5 to 16 years were similar to those in adults. Pharmacokinetics for younger patients were not performed.
**Geriatric Patients**: Elderly patients may have higher unbound plasma fractions of naproxen, indicating potential sensitivity to adverse effects.
**Hepatic and Renal Impairment**: Naproxen is extensively metabolized in the liver and is predominantly excreted by the kidneys. Reduced excretion may occur in patients with severe renal impairment.
The information presented aims to ensure healthcare providers administer Naprosyn Tablets, EC-Naprosyn, and Anaprox DS appropriately, continuously evaluating the balance between potential benefits and risks [1]. Understanding these aspects assists in delivering safe and effective patient care [2].
