PRESCRIPTION DRUG
Buffered penicillin G potassium for injection is indicated in the treatment of serious infections caused by susceptible strains of the designated microorganisms in the conditions listed below. 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 Buffered penicillin G potassium for injection 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. Septicemia, empyema, pneumonia, pericarditis, endocarditis, meningitis Streptococcus pyogenes (group A beta-hemolytic streptococcus ), other beta-hemolytic streptococci including groups C, H, G, L and M, Streptococcus pneumoniae and Staphylococcus species (non-penicillinase producing strains) Anthrax Bacillus anthracis Actinomycosis (cer
Buffered penicillin G potassium for injection, USP, is supplied in dry powder form in vials containing: 1,000,000 units (1 million units) × 10’s (NDC 0781-6134-95) 5,000,000 units (5 million units) × 10’s (NDC 0781-6135-95) 20,000,000 units (20 million units) × 1’s (NDC 0781-6136-94) of crystalline penicillin G as the potassium salt; buffered with sodium citrate and citric acid to an optimum pH.

Abbreviated New Drug Application
PENICILLIN G POTASSIUM- PENICILLIN G POTASSIUM INJECTION, POWDER, FOR SOLUTION SANDOZ INC ---------- PENICILLIN G POTASSIUM FOR INJECTION, USP RX ONLY BUFFERED To reduce the development of drug-resistant bacteria and maintain the effectiveness of penicillin G potassium and other antibacterial drugs, penicillin G potassium should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. DESCRIPTION Buffered penicillin G potassium for injection, USP is sterile penicillin G potassium powder for reconstitution. It is an antibacterial agent intended for intravenous or intramuscularly use. Chemically, penicillin G potassium is monopotassium (2S,5R,6R)-3,3-dimethyl-7-oxo-6-(2- phenylacetamido)-4-thia-1-azabicyclo (3.2.0) heptane-2-carboxylate, and has the following chemical structure: MOLECULAR FORMULA: C H KN O S MOLECULAR WEIGHT: 372.48 Penicillin G potassium, a water soluble benzylpenicillin, is a white to almost white crystalline powder which is almost odorless and/or after reconstitution a colorless solution. The pH of freshly constituted solutions usually ranges from 6 to 8.5. Sodium citrate and citric acid have been added as a buffer. Buffered penicillin G potassium for injection, USP is supplied in vials equivalent to 1,000,000 units (1 million units), 5,000,000 units (5 million units), or 20,000,000 units (20 million units) of penicillin G as the potassium salt. Each million unit contains approximately 7.9 milligrams of sodium (0.34 mEq) and 65.6 milligrams of potassium (1.68 mEq). CLINICAL PHARMACOLOGY After an intravenous infusion of penicillin G, peak serum concentrations are attained immediately after completion of the infusion. In a study of ten patients administered a single 5 million unit dose of 16 17 2 4 penicillin G intravenously over 3 to 5 minutes, the mean serum concentrations were 400 mcg/mL, 273 mcg/mL and 3 mcg/mL at 5 to 6 minutes, 10 minutes and 4 hours after completion of the injection, respectively. In a separate study, five healthy adults we 阅读完整的文件
