LIMBITROL DS vs TEMAZ
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Limbitrol DS is a combination of amitriptyline (a tricyclic antidepressant) and chlordiazepoxide (a benzodiazepine). Amitriptyline inhibits the reuptake of serotonin and norepinephrine, enhancing neurotransmission in the CNS. Chlordiazepoxide binds to GABA-A receptors, potentiating GABAergic inhibitory effects, leading to anxiolytic and sedative effects.
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 tablet (amitriptyline 25 mg/chlordiazepoxide 10 mg) orally 3 times daily initially, gradually increasing to 2 tablets orally 3 times daily or 3 tablets orally twice daily if needed; maximum 6 tablets per day.
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
Chlordiazepoxide: 5-30 hours (parent drug), active metabolite (desmethylchlordiazepoxide) 10-30 hours; amitriptyline: 13-36 hours (parent), nortriptyline (active metabolite) 18-44 hours. Half-lives increase with age and hepatic impairment.
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: 70-80% as conjugated metabolites, <5% unchanged; fecal: 10-20% via biliary excretion.
Renal: ~80% as unchanged drug and metabolites; biliary/fecal: ~20%.
