DORIDEN vs EQUANIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Barbiturate-like sedative-hypnotic; acts on GABA-A receptors to enhance inhibitory neurotransmission, causing CNS depression.
Gamma-aminobutyric acid (GABA) receptor positive allosteric modulator; increases frequency of chloride channel opening, potentiating inhibitory neurotransmission.
500 mg orally at bedtime, maximum 1 g per day; for sedation, 250 mg 3 times daily after meals.
400 mg orally 3-4 times daily; maximum 2400 mg/day. Alternatively, 200 mg orally 3-4 times daily for mild anxiety.

Terminal elimination half-life is 4-10 hours in healthy adults; prolonged in elderly and patients with hepatic impairment, increasing to 12-20 hours.
Terminal elimination half-life is 6-20 hours (mean 10 hours). In hepatic cirrhosis, half-life may be prolonged to 24-36 hours due to impaired clearance.
Renal (accounting for approximately 80% of elimination, primarily as glucuronide conjugates and unchanged drug); biliary/fecal (minor, about 10%).
Primarily renal excretion of conjugated metabolites (inactive); approximately 90% of a dose is excreted in urine, with less than 10% in feces. Less than 5% is excreted unchanged.
