HYDROPANE vs TRICHLORMAS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thiazide diuretic; inhibits sodium chloride cotransporter in distal convoluted tubule, increasing excretion of sodium and water, and reducing plasma volume.
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.
50–100 mg orally once daily, maximum 200 mg 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.

Terminal elimination half-life is approximately 8-15 hours in patients with normal renal function; may be prolonged in renal impairment.
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.
Renal (approximately 50% as unchanged drug) and hepatic metabolism to inactive metabolites; fecal elimination accounts for about 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.
