Naproxen

Generic Name: Naproxen
Common Brand Names: Aleve, Naprosyn, Anaprox

Introduction

Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) widely used for its analgesic, antipyretic, and anti-inflammatory properties. It is commonly prescribed for managing pain and inflammation in musculoskeletal conditions and other inflammatory disorders.

Conditions of Use (Indications)

1. Pain Management:

  • Mild to moderate pain, including headache, dental pain, and menstrual cramps (dysmenorrhea).

2. Inflammatory Conditions:

  • Osteoarthritis, rheumatoid arthritis, ankylosing spondylitis.

3. Gout:

  • Acute gout attacks.

4. Fever Reduction (Off-Label):

  • In febrile illnesses when other antipyretics are unsuitable.

Mechanism of Action

Naproxen inhibits the cyclooxygenase (COX-1 and COX-2) enzymes, which are involved in the synthesis of prostaglandins. Prostaglandins mediate inflammation, pain, and fever. By reducing prostaglandin levels, naproxen alleviates these symptoms.

Side Effects

1. Common Side Effects:

  • Gastrointestinal discomfort, nausea, heartburn, headache, dizziness.

2. Serious Side Effects:

  • Gastrointestinal bleeding, peptic ulcers, acute kidney injury, elevated liver enzymes.

Harmful Interactions

1. Anticoagulants (e.g., warfarin, DOACs):

  • Increased risk of bleeding.

2. Corticosteroids:

  • Additive risk of gastrointestinal ulcers or perforation.

3.ACE Inhibitors, ARBs, and Diuretics:

  • Reduced renal function and increased risk of acute kidney injury.

4.SSRIs (e.g., citalopram):

  • Increased risk of gastrointestinal bleeding.

Contraindications

  1. Active gastrointestinal bleeding or history of peptic ulcers.
  2. Severe renal or hepatic impairment.
  3. Hypersensitivity to naproxen or other NSAIDs.
