LIMBITROL vs TEMAZ
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Limbitrol is a combination of chlordiazepoxide (a benzodiazepine) and amitriptyline (a tricyclic antidepressant). Chlordiazepoxide enhances GABA-A receptor activity, producing anxiolytic and sedative effects. Amitriptyline inhibits serotonin and norepinephrine reuptake, elevating mood and reducing pain. The combination is used for depression with anxiety.
Temazepam, a benzodiazepine, enhances the effect of gamma-aminobutyric acid (GABA) at the GABA-A receptor, increasing chloride ion conductance and causing neuronal hyperpolarization, leading to anxiolytic, sedative, and hypnotic effects.
1-2 tablets (5 mg chlordiazepoxide / 12.5 mg amitriptyline per tablet) orally 3-4 times daily. Maximum 6 tablets per day in divided doses.
Temazepam 15-30 mg orally at bedtime, up to 60 mg if needed.

Clinical Note
moderateTemazepam + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Temazepam is combined with Fluticasone propionate."
Clinical Note
moderateTemazepam + Teriflunomide
"The metabolism of Teriflunomide can be decreased when combined with Temazepam."
Clinical Note
moderateTemazepam + Haloperidol
"The risk or severity of adverse effects can be increased when Temazepam is combined with Haloperidol."
Clinical Note
moderateTemazepam + Sulfisoxazole
Amitriptyline: 20-30 hours (range 10-46 h) with a terminal elimination half-life of ~24 h; clinical significance requires 7-14 days to reach steady state. Chlordiazepoxide: 5-30 hours (up to 48 h for active metabolite desmethylchlordiazepoxide).
Terminal elimination half-life: 1.5–2 hours; in severe renal impairment (CrCl <30 mL/min), half-life may extend to 4–6 hours, requiring dose adjustment.
Renal (approximately 70-80% as metabolites, 1-3% unchanged) and fecal (20-30% via biliary elimination for chlordiazepoxide component; amitriptyline is primarily excreted renally as metabolites, 10-15% unchanged).
Renal: ~80% as unchanged drug and metabolites; biliary/fecal: ~20%.
