Chloroquine tablets nhs Hydroxychloroquine dose medscape Tinnitus and hydroxychloroquine CLINICAL PHARMACOLOGY. Chloroquine is rapidly and almost completely absorbed from the gastrointestinal tract, and only a small proportion of the administered dose is found in the stools. Approximately 55% of the drug in the plasma is bound to nondiffusible plasma constituents. Abstract. The 4-aminoquinolines are weak bases that are completely absorbed from the gastrointestinal tract, sequestered in peripheral tissues, metabolized in the liver to pharmacologically active by-products, and excreted via the kidneys and the feces. This chapter covers the pharmacology of chloroquine and hydroxychloroquine, which is similar for both drugs, but the details are different. For example, both drugs are partially excreted in feces, but the proportions differ slightly—8–10 % for chloroquine and 15–24 % for hydroxychloroquine. One dose is taken beginning 2 weeks before traveling to an area where malaria is common, while you are in the area, and then for 8 weeks after you return from the area. Your doctor will tell you how many tablets to take for each dose.
