How It Works in the Body

Layman’s Explanation (Canadian Patient-Friendly Tone)

Plaquenil works by attacking the function of certain cells in the immune system overactive in autoimmune diseases, helping to calm inflammation and alleviate symptoms. Think of it as a means to keep the immune system from overreacting. By doing so, it can reduce flare-ups in conditions like lupus and rheumatoid arthritis while also providing protection against malaria.

Patients should rest assured that this medication is relevant in treating their conditions. While it may take a few weeks to experience its full benefits, it is worth sticking with it as recommended by healthcare providers.

Clinical Detail from Health Canada Resources

Pharmacodynamically, Plaquenil is an aminoquinoline derivative that affects lysosomal pH in immune cells, inhibiting autoimmunity and inflammatory responses. The pharmacokinetics reveal that its absorption occurs in the gastrointestinal tract, providing peak plasma concentrations 2-6 hours post-dosing, with a half-life ranging from 30 to 60 days. The drug predominantly accumulates in tissues, particularly the liver, lungs, and skin, thus impacting its safety profile and necessity for regular monitoring during treatment.

Dosage & Administration

Standard Regimens per Canadian Guidelines

Canadian healthcare guidelines outline specific dosages for various conditions treated with Plaquenil. Generally, the recommendations include:

• Malaria prophylaxis: Adults typically take 400 mg per week, while pediatric doses are based on weight (up to 6.5 mg/kg).
• Malaria treatment: An initial dose of 800 mg, followed by 400 mg at intervals of 6, 24, and 48 hours, with adjustments based on total weight.
• Rheumatoid Arthritis and SLE: Dosage ranges from 200 mg to 400 mg daily, often continued indefinitely, with regular evaluations.

Adjustments by Patient Type (with Canadian Clinical Notes)

Dosage adjustments may become necessary in particular patient populations:

• Elderly patients: Due to a higher risk of retinal toxicity and other side effects, dosages may need careful management.
• Children: Adhering strictly to weight-based measurements to ensure safety; ongoing ophthalmologic examinations are crucial.
• Patients with kidney/liver impairment: These populations might require lower dosages and thorough monitoring through bloodwork.

Close follow-ups can help manage side effects effectively, ensuring optimal drug efficacy and patient safety.
