WebChlorthalidone is an oral diuretic with prolonged action (48–72 hours) and low toxicity. The major portion of the drug is excreted unchanged by the kidneys. The diuretic effect of the drug occurs in approximately 2.6 hours and continues for up to 72 hours. The mean half-life following a 50 to 200 mg dose is 40 hours. WebAbstract. Diuretics act primarily by blocking reabsorption of sodium at four major sites in the nephron. Clinically useful agents that block sodium reabsorption effectively in the proximal tubule are lacking. Furosemide (Lasix), ethacrynic acid (Edecrin), and possibly organomercurial agents are effective in the ascending limb of Henle's loop.
