Pharmacology

đŸ”Ŧ

Mechanism of Action

Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that exerts its anti-inflammatory, analgesic, and antipyretic effects by reversibly inhibiting cyclooxygenase (COX-1 and COX-2) enzymes. This inhibition leads to a reduction in the synthesis of prostaglandins, which are mediators of inflammation, pain, and fever.

Precautions & Cautions

It is essential to inform all your healthcare providers, including doctors, nurses, pharmacists, and dentists, that you are taking this medication. If you are taking this drug for an extended period, your doctor may recommend regular blood tests to monitor your condition.

This medication may interfere with certain laboratory tests, so it is crucial to notify all your healthcare providers and lab personnel that you are taking this drug. There is a risk of developing high blood pressure with medications like this one, so your doctor may advise you to have your blood pressure checked regularly.

Before consuming alcohol, discuss the potential risks with your doctor. If you smoke, talk to your doctor about the possible effects on your health. It is vital to follow your doctor's instructions regarding the dosage and duration of treatment. Taking more than the prescribed amount or using the medication for longer than recommended may increase your risk of severe side effects.

If you have asthma, consult your doctor, as you may be more sensitive to this medication. Additionally, this drug may affect your blood's ability to clot, making you more prone to bleeding. To minimize this risk, be cautious and avoid injuries, use a soft toothbrush, and consider using an electric razor.

The use of medications like this one may increase the risk of heart failure, particularly in people who already have this condition. This can lead to a higher chance of heart attack, hospitalization for heart failure, and death. Discuss these risks with your doctor. Furthermore, people who have had a recent heart attack may have a higher risk of heart attack and heart-related death when taking this type of medication. In fact, studies have shown that individuals taking drugs like this one after a first heart attack were more likely to die within the following year compared to those not taking these medications.

If you are taking aspirin to help prevent a heart attack, consult your doctor about the potential interactions. If you are on a low-sodium or sodium-free diet, inform your doctor, as some formulations of this medication may contain sodium.

Older adults (60 years or older) should use this medication with caution, as they may be more susceptible to side effects. Women of childbearing age should be aware that NSAIDs like this drug may affect ovulation, potentially impacting fertility. However, this effect is reversible, and ovulation typically returns to normal once the medication is stopped. If you are planning to become pregnant or are concerned about fertility, discuss these issues with your doctor.

Breastfeeding mothers should inform their doctor, as they will need to discuss the potential risks and benefits of taking this medication while nursing their baby.

Special Patient Groups

🤰

Pregnancy

Avoid use during the third trimester of pregnancy due to the risk of premature closure of the fetal ductus arteriosus and fetal renal dysfunction. Use in the first and second trimesters should only be considered if the potential benefit justifies the potential risk to the fetus.

Trimester-Specific Risks:

First Trimester: Possible increased risk of miscarriage and congenital malformations (data inconsistent).
Second Trimester: Generally considered safer than third trimester, but still use with caution and lowest effective dose for shortest duration.
Third Trimester: Contraindicated due to risk of premature closure of ductus arteriosus, persistent pulmonary hypertension, oligohydramnios, and renal dysfunction in the fetus.
🤱

Lactation

Naproxen is excreted in breast milk in small amounts. Generally considered compatible with breastfeeding, but use with caution, especially in preterm or jaundiced infants. Monitor infant for adverse effects.

Infant Risk: Low risk of adverse effects; monitor for drowsiness, poor feeding, or rash.
đŸ‘ļ

Pediatric Use

Not recommended for children under 12 years of age without physician consultation due to limited safety and efficacy data in this age group for OTC use. Risk of Reye's syndrome is not associated with naproxen, but caution is still advised.

👴

Geriatric Use

Elderly patients are at increased risk for serious adverse reactions, including gastrointestinal bleeding, ulceration, perforation, renal impairment, and cardiovascular events. Use the lowest effective dose for the shortest duration possible. Monitor renal function and signs of GI bleeding closely.

Clinical Information

💎

Clinical Pearls

  • Naproxen sodium has a longer half-life than ibuprofen, allowing for less frequent dosing (every 8-12 hours vs. every 4-6 hours).
  • Advise patients to take with food, milk, or antacids to minimize GI upset.
  • Educate patients on the signs and symptoms of serious cardiovascular and GI adverse events, and when to seek immediate medical attention.
  • Remind patients that OTC naproxen sodium is not for long-term chronic pain management without physician supervision.
  • Caution against concomitant use with other NSAIDs (including aspirin for pain relief, but low-dose aspirin for cardiovascular protection may be continued under medical advice, with increased GI risk).
🔄

Alternative Therapies

  • Acetaminophen (e.g., Tylenol) for pain and fever (different mechanism, no anti-inflammatory effect, different side effect profile).
  • Ibuprofen (another NSAID, shorter half-life, similar risks).
  • Aspirin (another NSAID, antiplatelet effects, higher GI risk at analgesic doses).
  • Topical NSAIDs (e.g., diclofenac gel) for localized pain, with lower systemic absorption.
  • Non-pharmacological therapies (e.g., RICE - Rest, Ice, Compression, Elevation; physical therapy; heat/cold therapy).
