AZILSARTAN MEDOXOMIL AND CHLORTHALIDONE vs TRICHLORMAS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Azilsartan medoxomil is an angiotensin II receptor antagonist that selectively blocks the binding of angiotensin II to AT1 receptors, reducing vasoconstriction and aldosterone secretion. Chlorthalidone is a thiazide-like diuretic that inhibits sodium reabsorption in the distal convoluted tubule, increasing sodium and water excretion.
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.
Azilsartan medoxomil 40 mg/chlorthalidone 12.5 mg or 25 mg orally once daily; maximum dose: azilsartan medoxomil 40 mg/chlorthalidone 25 mg per 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.

Azilsartan medoxomil: Terminal half-life approximately 11 hours. Chlorthalidone: Long terminal half-life of 40-60 hours (mean 47 hours), 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.
Azilsartan medoxomil: Approximately 55% of the dose is excreted in feces and 42% in urine, mostly as metabolites. Chlorthalidone: Primarily excreted unchanged in urine (50-70%) via tubular secretion; approximately 30% is excreted in feces via biliary elimination.
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.
