METHYCLOTHIAZIDE vs TRICHLORMAS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thiazide-like diuretic that inhibits sodium-chloride symporter in distal convoluted tubule, increasing excretion of sodium, chloride, and water. Reduces peripheral vascular resistance.
TRICHLORMAS is a sedative-hypnotic agent. Its mechanism of action is not fully understood but is believed to involve potentiation of GABAergic inhibition in the central nervous system, similar to other chloral derivatives. It is metabolized to trichloroethanol, which is the active hypnotic compound.
2.5-10 mg orally once daily.
500 mg orally once daily at bedtime, increased as needed to a maximum of 1 g per day in divided doses; for insomnia, 1-2 g orally at bedtime.

moderateMethyclothiazide + Digoxin
"The risk or severity of adverse effects can be increased when Methyclothiazide is combined with Digoxin."

Clinical Note
moderateTerminal elimination half-life: ~40 hours (range 30-50 h); due to extensive tubular reabsorption, half-life is prolonged in renal impairment and elderly, allowing once-daily dosing
Terminal elimination half-life is approximately 8-11 hours for the parent drug in adults with normal renal function. In patients with hepatic impairment, half-life may be prolonged up to 30 hours; in severe renal impairment, half-life of metabolites may increase significantly.
Primarily renal (70-80% as unchanged drug via tubular secretion and glomerular filtration); minor biliary/fecal (<10%)
Primarily renal via glomerular filtration and tubular secretion; about 70-80% of the dose excreted unchanged in urine within 24 hours. The remainder is metabolized to trichloroethanol (active) and trichloroacetic acid; these metabolites are also eliminated renally.
