✔️ Pharmacology

Naproxen is a prototypical NSAID (Non-steroidal anti-inflammatory drug) and belongs to the class of propionic acid derivatives. It works by reversibly inhibiting the cyclooxygenase-1 and -2 (COX-1 and -2) enzymes, leading to a reduction in the synthesis of prostaglandin precursors. This inhibition can result in anti-inflammatory, analgesic (pain-relieving), and antipyretic (fever-reducing) effects. Naproxen can also inhibit platelet aggregation, which is why it is advised to be cautious in patients with blood clotting problems.

✔️ Interaction

• Naproxen can interact with several medications and substances, leading to potential adverse effects or reduced efficacy. Here is a summary of some of the notable interactions:
• Methotrexate: Naproxen may enhance the toxicity of methotrexate, a medication used to treat certain cancers and autoimmune conditions.
• ACE inhibitors and Angiotensin II receptor antagonists: Naproxen may reduce the blood pressure-lowering effect of these antihypertensive medications.
• Aspirin: Concurrent use of naproxen and aspirin may increase the risk of serious gastrointestinal (GI) events, such as ulcers.
• Warfarin: Naproxen can increase the risk of gastrointestinal bleeding when used with warfarin, an anticoagulant medication.
• Furosemide and Thiazide diuretics: Naproxen may reduce the natriuretic (water and salt elimination) effects of these diuretic medications.
• Lithium: Naproxen may increase serum lithium concentrations and decrease renal lithium clearance, potentially leading to higher lithium levels in the blood.
• Antacids, Colestyramine, and Sucralfate: These medications may delay the absorption of naproxen.
• Beta-blockers (e.g., propranolol): Naproxen may interfere with the antihypertensive effects of beta-blockers.
• Probenecid: Naproxen levels in the blood may increase when used with probenecid, a medication used to treat gout.

✔️ Contraindications

✔️ Pregnancy & Lactation

Naproxen is classified as a pregnancy category C medication by the US Food and Drug Administration (FDA). Pregnancy category C indicates that animal studies have shown adverse effects on the fetus, but there are limited human studies, and the potential benefits to the mother may outweigh the risks to the fetus.

During pregnancy, Naproxen should be used only if deemed essential by the healthcare provider and if the potential benefits to the mother outweigh the potential risks to the unborn child. It should be used at the lowest effective dose and for the shortest duration possible.

Naproxen is also not recommended during breastfeeding as it can pass into breast milk and may harm the nursing infant. If a woman needs to take Naproxen while breastfeeding, it's important to consult with a healthcare provider to weigh the risks and benefits and explore alternative medications that are safer during lactation.

Overall, it's crucial for pregnant or breastfeeding women to seek medical advice and supervision before taking any medications to ensure the safety of both the mother and the baby.

✔️ Precautions & Warnings

Patients with known cardiovascular (CV) disease or risk factors, history of gastrointestinal (GI) bleeding or peptic ulceration, fluid retention, or heart failure should use Naproxen with caution or avoid it altogether, as it may exacerbate these conditions.

• Naproxen should be used with caution in patients with hepatic and renal impairment, as it may affect liver and kidney function.
• Elderly patients should also use Naproxen with caution, as they may be more prone to certain side effects.
• Naproxen is not recommended during pregnancy and lactation, as it may pose risks to the developing fetus and nursing infant. Pregnant and breastfeeding women should consult their healthcare provider for safer alternatives.
• Patients taking Naproxen should be advised that it may impair their ability to drive or operate machinery, and they should exercise caution while performing such activities.
• During therapy with Naproxen, blood pressure should be closely monitored, especially during initiation and long-term treatment. Regular monitoring of renal function, complete blood count (CBC), and chemistry profile may also be necessary for patients receiving long-term therapy.
• For lactating women, it is important to note that Naproxen is excreted in breast milk, and its effect on the nursing infant is unknown. Therefore, it is not recommended during breastfeeding.

As with any medication, patients should follow their healthcare provider's instructions and report any adverse effects or concerns promptly. It's essential to have open communication with the healthcare provider to ensure the safe and effective use of Naproxen.
