HYDROCHLOROTHIAZIDE vs TRICHLORMAS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thiazide diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the kidney, reducing reabsorption of sodium and chloride, leading to increased excretion of water and electrolytes.
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: 25-100 mg daily in 1-2 divided doses. Maximum dose 200 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.

Clinical Note
moderateTerminal elimination half-life is 5.6–14.8 hours (mean ~9 hours). In patients with renal impairment (CrCl <30 mL/min), half-life is prolonged up to 24–48 hours, necessitating dose adjustment.
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 (≥95%) via glomerular filtration and tubular secretion, with approximately 60% of the dose excreted unchanged in urine. Minor biliary/fecal excretion accounts for <5%.
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.
