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.

Approved Use

Penicillin G Sodium for Injection, USP is indicated in the treatment of serious infections caused by susceptible strains of the designated microorganisms. Appropriate culture and susceptibility tests should be done before treatment in order to isolate and identify organisms causing infection and to determine their susceptibility to penicillin G. Therapy with Penicillin G Sodium for Injection, USP may be initiated before results of such tests are known when there is reason to believe the infection may involve any of the organisms listed below, however, once these results become available, appropriate therapy should be continued

Sample Use Guides

Serious infections due to susceptible strains of streptococci (including S. pneumoniae): 5 to 24 million units/day depending on the infection and its severity administered in equally divided doses every 4 to 6 hours Anthrax: Minimum of 8 million units/day in divided doses every 6 hours. Higher doses may be required depending on susceptibility of organism 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 Listeria infections, Meningitis: 15 to 20 million units/day for 2 weeks
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.
