Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bristagen (amikacin) is an aminoglycoside antibiotic that irreversibly binds to the 30S ribosomal subunit, inhibiting bacterial protein synthesis.
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.
1-2 mg/kg IM or IV every 8-12 hours; typical adult dose is 1 mg/kg every 8 hours.
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.

2.5 hours (prolonged to 20-40 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 (90% unchanged via glomerular filtration); biliary/fecal excretion <10%.
Primarily renal excretion of unchanged drug via glomerular filtration; >90% of absorbed dose excreted in urine within 24 hours; negligible biliary/fecal elimination.
