GENOSYL vs GENTAMICIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Genosyl (sodium phenylbutyrate) is a prodrug that is metabolized to phenylacetate, which conjugates with glutamine via acetylation to form phenylacetylglutamine. This alternative pathway facilitates waste nitrogen excretion in patients with urea cycle disorders.
Binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibition of protein synthesis; bactericidal against gram-negative aerobes.
5 mg orally once daily for 14 days, then 2.5 mg orally once daily thereafter.
5-7 mg/kg/day IV or IM in divided doses every 8 hours; for serious infections, up to 5 mg/kg/day IV in 3 divided doses.

Terminal half-life 3.5 hours; clinically relevant for dosing every 6-8 hours in renal impairment.
Clinical Note
moderateGentamicin + Digoxin
"The serum concentration of Digoxin can be decreased when it is combined with Gentamicin."
Clinical Note
moderateGentamicin + Digitoxin
"The serum concentration of Digitoxin can be decreased when it is combined with Gentamicin."
Clinical Note
moderateGentamicin + Deslanoside
"The serum concentration of Deslanoside can be decreased when it is combined with Gentamicin."
Clinical Note
moderateGentamicin + Acetyldigitoxin
2-3 hours in adults with normal renal function; prolonged to 24-48 hours in anuria; adjust dosing based on renal function.
Renal: 85% unchanged; biliary/fecal: 15% as metabolites.
Primarily renal (glomerular filtration): 90-95% unchanged in urine over 24 hours; biliary/fecal: <2%.
