Pattern of Retinopathy: Although the locus of toxic damage is parafoveal in many eyes, Asian patients often show an extramacular pattern of damage. Dose: We recommend a maximum daily HCQ use of 5.0 mg/kg real weight, which correlates better with risk than ideal weight. Plaquenil birth defects Plaquenil sun tan A metabolite of chloroquine – hydroxychloroquine – has a long half-life 32–56 days in blood and a large volume of distribution 580–815 L/kg. The therapeutic, toxic and lethal ranges are usually considered to be 0.03 to 15 mg/l, 3.0 to 26 mg/l and 20 to 104 mg/l, respectively. The amount of hydroxychloroquine excreted in the urine as unchanged drug ranges from 6% to 60% median 23%, and 17% is excreted in the urine as metabolized drug. Twenty-four percent to 25% of hydroxychloroquine is excreted in feces, 5% is sloughed off in skin, and 45% is stored in lean tissues. Hydroxychloroquine HCQ, a commonly used antimalarial drug in rheumatic diseases, has shown favorable metabolic effects on both glucose control and lipid profiles. We describe a case of a young woman with type 1 diabetes whose glycemic control was optimized with the introduction of HCQ as a treatment for her Sjogren syndrome in addition to a subtle yet measurable improvement in her lipid profile. Risk of Toxicity: The risk of toxicity is dependent on daily dose and duration of use. There are no similar demographic data for CQ, but dose comparisons in older literature suggest using 2.3 mg/kg real weight.

Pharmacokinetic PK and pharmacodynamic PD studies with HCQ have shown that drug exposure in the blood does not correlate with autophagy inhibition in either peripheral blood mononuclear cells or tumor tissue. To better explain this PK/PD. Hydroxychloroquine A Physiologically-Based.. A favorable effect of hydroxychloroquine on glucose and lipid.. Long-term effects of of hydroxychloroquine on metabolism.. Jan 05, 2020 Hydroxychloroquine is a well tolerated medication for various rheumatologic and dermatologic conditions. Its main side effects are gastrointestinal upset, skin rash, headache, and ocular toxicity. Within the eye, hydroxychloroquine negatively impacts the cornea, ciliary body, and retina.
