    Plaquenil and ocular toxicity


    Her rheumatologist instructed her to undergo a baseline ocular examination prior to initiating Plaquenil (hydroxychloroquine, Sanofi-Aventis) therapy. Toxic maculopathy associated with chloroquine use was first documented in the literature five decades ago.1 In the United States, Plaquenil––an analog to chloroquine––is used to treat a variety of conditions, including rheumatoid arthritis, lupus and several distinct inflammatory disorders. Although the incidence of macular toxicity is infrequent with Plaquenil use (at a dosage of 200mg or 400mg q.d.), its visual impact can be devastating.

    The American Academy of Ophthalmology has published several dosing and screening recommendations for hydroxychloroquine to avoid potential retinal toxicity, yet some patients still experience permanent vision loss resulting from hydroxychloroquine retinopathy due to improper dosing of the drug and improper screening. Once retinal toxicity from hydroxychloroquine occurs, it is thought that the retinal changes are permanent and the disease can progress even if hydroxychloroquine is stopped for 1 to 3 years. Newer techniques for evaluation of retinal disease have been developed and these techniques can detect retinal toxicity earlier. What is plaquenil? Plaquenil is a medication commonly used in patients that have Rheumatoid Arthritis RA, Systemic Lupus Erythematosus SLE, Sjogrens Syndrome, and other inflammatory and autoiummune disorders. What are risk factors for developing retinal toxicity from Plaquenil? Age older than 60; Daily dose of more than 6.5mg/kg

    Ocular manifestations of hydroxychloroquine include corneal verticillata and retinal toxicity. Verticillata are cornea deposits of salts within the corneal epithelium. This condition does not cause symptoms and is reversible with cessation of the medication. Plaquenil Toxicity Plaquenil hydroxychloroquine is a medicine commonly used to treat patients with systemic lupus erythematosus and rheumatoid arthritis. After prolonged use, it can sometimes damage the macula and cause central vision loss. Plaquenil is a drug that is stored in high concentrations throughout the body and is very slowly eliminated from the body. It is attracted to the retinal pigmented epithelium in the back of the eye the retina. Although rare, Plaquenil can cause significant toxicity to the eye with prolonged use.

    Chloroquine & Hydroxychloroquine supporting chemo. Mechanism Endosomal Acidification Inhibitor Chloroquine is a lysosomotropic agent that prevents endosomal acidification. It accumulates inside the acidic parts of the cell, including endosomes and lysosomes. This accumulation leads to inhibition of lysosomal enzymes that require an acidic pH, and prevents fusion of endosomes and lysosomes.
