Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibition of sodium-chloride symporter (NCC) in the distal convoluted tubule of the kidney, reducing sodium and chloride reabsorption and promoting diuresis.
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.
Oral: 5-10 mg once daily, preferably in the morning. Maximum dose 20 mg/day.
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.

Terminal elimination half-life is 6-12 hours; prolonged in renal impairment (up to 20-30 hours) or heart failure due to reduced renal perfusion.
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 elimination; approximately 60-80% excreted unchanged in urine via tubular secretion; minor biliary/fecal excretion (<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.
