    There are hundreds of drugs with potential retinal toxicity—so many that the National Registry of Drug-Induced Ocular Side Effects doesn’t stratify them by incidence or effect, said Frederick W. “Rick” Fraunfelder, MD, director of the Registry and associate professor of ophthalmology at Oregon Health & Science University in Portland.

    Nov 02, 2010 Hydroxychloroquine has an extremely long half life of around 32 days. This means that every 32 days, half of the previous amount of hydroxychloroquine in the body disappears. It takes around 5.5 half lives for a drug to be completely eliminated from your body meaning that you may need to wait for around 176 days. Plaquenil’s long half-life in the body can cause irreversible and progressive damage, Dr. Fung said. Similarly, one study reported that 16 women who’d taken hydroxychloroquine or chloroquine, or a combination of the agents, showed no improvement seven years after stopping drug therapy, and progression occurred in six of the cases. 2 Jan 03, 2020 The absorption half-life was approximately 3 to 4 hours and the terminal half-life ranged from 40 to 50 days. The long half-life can be attributed to extensive tissue uptake rather than through decreased excretion. Peak plasma levels of hydroxychloroquine were seen in about 3 to 4 hours.

    “It’s a pretty rare thing.” Nevertheless, he urged doctors to master the Academy’s new guidelines, because the effects from chloroquine and hydroxychloroquine, when they do occur, are severe and often irreversible. “Plaquenil toxicity isn’t even in the top 10, or the top 100” if you’re looking at incidence, he said.

    Typical daily doses of 200 to 600 mg are used for lupus and rheumatoid diseases. Hydroxychloroquine has a long terminal elimination half-life in blood 40 days, which exceed those in plasma. The oral bioavailability averages 79%. Hydroxychloroquine accumulates in several organs, especially melanin-containing retina and skin. Half-life Terminal elimination half-life In blood Approximately 50 days. In plasma Approximately 32 days {68}. Time to peak concentration Approximately 3.2 hours range, 2 to 4.5 hours {68}. Peak concentrations Steady state concentration in whole blood achieved at 6 months 155 mg base daily 948 nanograms per mL. Half-life T ½ In a bioavailability study of 5 healthy participants receiving 1 oral and 1 intravenous IV dose of hydroxychloroquine sulfate 200 mg 155 mg base administered on separate occasions, the mean terminal elimination half-life of hydroxychloroquine, as calculated from blood data, was more than 40 days for both the oral and IV doses. 12
