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.
Paromomycin is an aminoglycoside antibiotic that binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibition of protein synthesis in susceptible bacteria. It also has direct amebicidal activity against Entamoeba histolytica by inhibiting protein synthesis.
5 mg orally once daily for 14 days, then 2.5 mg orally once daily thereafter.
25-35 mg/kg/day orally in 3 divided doses for 5-10 days for intestinal amebiasis; 1 g orally every 8 hours for 7 days for cryptosporidiosis.

Terminal half-life 3.5 hours; clinically relevant for dosing every 6-8 hours in renal impairment.
Terminal elimination half-life: 2–3 hours in normal renal function; extends to 24–48 hours or longer in severe renal impairment, necessitating dose adjustment.
Renal: 85% unchanged; biliary/fecal: 15% as metabolites.
Primarily renal excretion of unchanged drug via glomerular filtration; >90% of absorbed dose excreted in urine within 24 hours; negligible biliary/fecal elimination.
