Penicillin G, also known as benzylpenicillin, is a penicillin derivative commonly used in the form of its sodium or potassium salts in the treatment of a variety of infections. It is effective against most gram-positive bacteria and against gram-negative cocci. It is administered intravenously or intramuscularly due to poor oral absorption. Penicillin G may also be used in some cases as prophylaxis against susceptible organisms. Microbiology Penicillin G is bactericidal against penicillin-susceptible microorganisms during the stage of active multiplication. It acts by inhibiting biosynthesis of cell-wall mucopeptide. It is not active against the penicillinase-producing bacteria, which include many strains of staphylococci. Penicillin G is highly active in vitro against staphylococci (except penicillinase-producing strains), streptococci (groups A, B, C, G, H, L and M), pneumococci and Neisseria meningitidis. Other organisms susceptible in vitro to penicillin G are Neisseria gonorrhoeae, Corynebacterium diphtheriae, Bacillus anthracis, clostridia, Actinomyces species, Spirillum minus, Streptobacillus monillformis, Listeria monocytogenes, and leptospira; Treponema pallidum is extremely susceptible. Adverse effects can include hypersensitivity reactions including urticaria, fever, joint pains, rashes, angioedema, anaphylaxis, serum sickness-like reaction.

Actinomycosis: 1 to 6 million units/day
Diphtheria (adjunctive therapy to antitoxin and for the prevention of the carrier state): 2 to 3 million units/day in divided doses for 10 to 12 days

Route of Administration:
Other
It was studied the antioxidant activity of penicillin G (PG) through its reactivity towards reactive oxygen species (superoxide anion radical, O2•̅; hydroxyl radical, HO• ; peroxyl radical, ROO• ; hydrogen peroxide, H2 O2 ; DPPH• ) using various in vitro antioxidant assays with chemiluminescence (CL) and spectrophotometry as measurement techniques. In hydroxyl radical assays , PG was found to inhibit the CL signal arising from the Fenton-like reaction in a dose-dependent manner with IC50 = 0.480 ± 0.020 mM. The highest reactivity of PG among the tested penicillins towards the HO radical was confirmed in the deoxyribose degradation assay.
