DIAZEPAM vs KLONOPIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzodiazepine that enhances GABA-A receptor activity by increasing the frequency of chloride channel opening, leading to neuronal hyperpolarization and inhibition.
Benzodiazepine that binds to GABA-A receptors at the benzodiazepine binding site, enhancing the effect of GABA and increasing chloride ion influx, leading to neuronal hyperpolarization and decreased neuronal excitability.

Terminal half-life 30-56 hours (range 20-70 hours) in adults; prolonged in elderly (up to 100 hours), neonates (up to 100 hours), and cirrhosis (up to 100+ hours).
Clinical Note
moderateDiazepam + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Diazepam is combined with Fluticasone propionate."
