    This dose should not exceed 6.5 mg/kg/day (calculated from ideal body weight and not actual body weight) and will be either 200 mg or 400 mg per day. In patients able to receive 400 mg daily: Initially 400 mg daily in divided doses.

    The mean time to peak plasma concentration was 1.83 hours. The mean plasma elimination half-life varied, depending on the post-administration period, as follows 5.9 hours at C max-10 hours, 26.1 hours at 10-48 hours and 299 hours at 48-504 hours. The parent compound and metabolites are widely distributed in the body and elimination is. The terminal elimination half-life of hydroxychloroquine is more than 40 days, thus blood and urine samples were collected for 5 months following each dose to characterise adequately the terminal elimination phase and obtain accurate estimates of the areas under the concentration-time curves. 3. The half-life of this initial phase is approximately 2 to 4 minutes. An intermediate phase follows, with a half-life on average of 30 minutes that coincides with loss of the pharmacodynamic effect. The terminal phase consists of a decline in plasma concentration with a half-life of approximately 2 hours.

    The maintenance dose should be increased to 400 mg daily if the response lessens. The dose can be reduced to 200 mg when no further improvement is evident.

  5. Jan 12, 2017 Young females exhibited slightly lower plasma concentrations relative to young males. After single doses of 7.5 mg meloxicam, the mean elimination half-life was 19.5 hours for the female group as compared to 23.4 hours for the male group. At steady state, the data were similar 17.9 hours vs. 21.4 hours.

    May 02, 2018 The half-life of elimination of hydroxychloroquine is 40 to 50 days, with half of the drug excreted renally in a concentration-dependent fashion. 22,23 The drug reaches 95% of its steady-state concentration by about 6 months of therapy. Shorter durations of therapy do not provide adequate time for the drug to achieve steady-state concentration. 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. I say this because Plaquenil has a chemical half-life of 30-60 days you can confirm this on wiki or RX info on the drug--so it takes a LONG time to get out of your system.long for you to notice changes in days. Half-life Terminal elimination half-life In blood Approximately 50 days. In plasma Approximately 32 days {68}.
