Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzathine penicillin G inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity and autolysin inhibition, leading to cell lysis.
VEETIDS (generic: voretigene neparvovec) is an adeno-associated virus vector-based gene therapy that delivers a functional copy of the RPE65 gene to retinal pigment epithelial cells, restoring the visual cycle and improving vision in patients with biallelic RPE65 mutation-associated retinal dystrophy.
Benzathine penicillin G 1.2 million units intramuscularly once for early syphilis; 2.4 million units intramuscularly weekly for 3 weeks for late latent syphilis.
500 mg orally twice daily for 7-14 days.

Terminal elimination half-life: 0.5–1 hour (prolonged in renal impairment); clinical context: requires probenecid for extended action
Terminal elimination half-life is 1.5-2 hours in adults with normal renal function; extends to 6-10 hours in moderate renal impairment.
Primarily renal (60–70% unchanged via glomerular filtration and tubular secretion); minor biliary/fecal elimination (<10%)
Renal elimination (60-80% unchanged); biliary/fecal excretion accounts for 15-20%.
