Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin G benzathine and penicillin G procaine are beta-lactam antibiotics that inhibit bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking, leading to cell lysis via autolytic enzymes. Synergistic action covers both susceptible Gram-positive cocci (e.g., Streptococcus pyogenes) and some Gram-negative cocci (e.g., Neisseria spp.).
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.
Intramuscular injection: 1.2 mL (900,000 units penicillin G benzathine and 300,000 units penicillin G procaine) every 48 hours for 3 doses; for severe infections, up to 2.4 mL (1,800,000/600,000 units) as a single dose.
500 mg orally twice daily for 7-14 days.

0.5-1 hour for penicillin G; prolonged to 3-6 hours in renal impairment. Procaine component has no significant effect on elimination half-life
Terminal elimination half-life is 1.5-2 hours in adults with normal renal function; extends to 6-10 hours in moderate renal impairment.
Renal: 60-90% as unchanged drug; biliary/fecal: minor (less than 10%)
Renal elimination (60-80% unchanged); biliary/fecal excretion accounts for 15-20%.
