What is the main difference between penicillin V and penicillin G?
The two so-called natural penicillins are both produced biosynthetically from Penicillium chrysogenum by fermentation. Benzylpenicillin (penicillin G) is formed if phenylacetic acid is added to the culture medium and Phenoxymethylpenicillin (penicillin V) is formed when phenoxyacetic acid is added.
What type of penicillin is penicillin G?
Benzylpenicillin (Penicillin G) is narrow spectrum antibiotic used to treat infections caused by susceptible bacteria. It is a natural penicillin antibiotic that is administered intravenously or intramuscularly due to poor oral absorption.
Is penicillin the same as penicillin G?
Penicillin G injection is used to treat and prevent certain infections caused by bacteria. Penicillin G injection is in a class of medications called penicillins. It works by killing bacteria that cause infections.
How is penicillin G different?
Penicillin G degrades more easily by stomach acid and has less than 30% bioavailability; therefore, it is a parenterally administered drug. Because of the short half-life, penicillin G is usually administered in divided doses 4 to 6 hours apart via the intravenous or intramuscular route.
What is another name for penicillin G?
Benzylpenicillin, also known as penicillin G (PenG) or BENPEN, and in military slang "Peanut Butter Shot" is an antibiotic used to treat a number of bacterial infections. This includes pneumonia, strep throat, syphilis, necrotizing enterocolitis, diphtheria, gas gangrene, leptospirosis, cellulitis, and tetanus.
What is penicillin G used for?
Penicillin G benzathine injection is used to treat bacterial infections (eg, mild to moderate infections of the upper respiratory tract, syphilis, yaws, bejel, pinta). It is also used to prevent rheumatic fever, chorea, rheumatic heart disease, or acute glomerulonephritis. This medicine is an antibiotic.
Is there different types of penicillin?

How many types of penicillin are there?
The penicillins are the most commonly used antibiotics in pediatrics and can be divided broadly into four different groups: (1) natural penicillins, (2) penicillinase-stable penicillins, (3) aminopenicillins, and (4) extended-spectrum penicillins.
How strong is penicillin G?
For penicillin G: For bacterial infections: For oral dosage form (oral solution, oral suspension, and tablets): Adults and teenagers—200,000 to 500,000 Units (125 to 312 milligrams [mg]) every four to six hours.
Why is penicillin G not given IV?
Penicillin G benzathine and penicillin G procaine injection should never be given intravenously (into a vein), because this may cause serious or life-threatening side effects or death.
Is penicillin more effective against gram-positive?
Gram-positive bacteria have a peptidoglycan layer on the outside of the cell wall. Gram-negative bacteria have peptidoglycan between membranes. Penicillin works best on gram-positive bacteria by inhibiting peptidoglycan production, making the cells leaky and fragile.
Is penicillin stronger than amoxicillin?
Is amoxicillin or penicillin more effective? Although both antibiotics are effective for treating bacterial infections, their effectiveness depends on the bacteria causing the infection. Amoxicillin is able to get rid of a broader range of bacteria compared to penicillin.

Is penicillin G narrow spectrum antibiotic?
Penicillin G has been in clinical use since the 1940s and continues to have an important role in the treatment of bacterial IE. While penicillin G is a narrow-spectrum antibiotic, it is reliably active against many gram-positive pathogens that cause IE, most notably streptococci and enterococci.
Is penicillin gram-positive or negative?
Penicillin is effective only against Gram-positive bacteria because Gram negative bacteria have a lipopolysaccharide and protein layer that surrounds the peptidoglygan layer of the cell wall, preventing penicillin from attacking.

The protein binding ability of this drug is about 80%, and the metabolism occurs in the liver. The excretion of penicillin V occurs in the kidney. The elimination half-life of penicillin V can range from 30 minutes to 60 minutes. The chemical formula of penicillin V is C16H18N2O5S.
How is penicillin G produced?from differencebetween.com
The production of penicillin G involves several steps, including fermentation, recovery, and purification of penicillin. During fermentation, the presence of the product in the solution can inhibit the reaction rate and yield; therefore, the product has to be continuously extracted. We can do it by mixing the mixture with glucose (or a similar sugar compound) and some small amounts of inorganic salts. We can use several methods in the recovery step of this drug; these include aqueous-two phase extraction, liquid membrane extraction, microfiltration, and solvent extraction. The final step is the purification step, where the penicillin G is separated from the extraction solution, which is performed through a separation column method.
Does penicillin cause jaundice?from ncbi.nlm.nih.gov
High doses of intravenous and intramuscular penicillin can be associated with serum aminotransferase elevations that are usually asymptomatic and resolve rapidly with stopping therapy or switching to another antibiotic (Case 1). Jaundiceand elevations in alkaline phosphatase are usually absent or mild. This type of hepatotoxicity is most common with oxacillin and carbenicillin, but can occur with parenteral forms of the first generation penicillins as well. This form of injury appears to be direct hepatotoxicity.

Does penicillin cause hepatic injury?from ncbi.nlm.nih.gov
The asymptomatic rise in serum aminotransferase levels after 4 weeks of high dose penicillin therapy and their fall once it was stopped is suggestive of penicillin induced direct hepatic injury. The onset and pattern of hepatic injury resembled the common hepatotoxicity of oxacillin with asymptomatic rises in aminotransferases that decrease rapidly when stopped and are often associated with eosinophilia. In the current case, other diagnoses could not be completely ruled out such as drug induced liver disease from other medications (low molecular weight heparin) or an underlying condition that led to the baseline, pre-penicillin ALTelevations.

This form of injury appears to be direct hepatotoxicity.
Is penicillin G a parenteral?
Penicillin G benzathine, potassium, procaine and sodium are currently available in the United States in parenteral formulations for intra venous or intramuscular use. Penicillin V potassium (also called phenoxymethyl penicillin) is a more acid stable and can be administered orally. Both Penicillin G and V are available in multiple generic formulations. The natural penicillins are indicated as therapy for mild-to-severe infections caused by susceptible organisms including (but not limited to) streptococcal infections and pneumonia, enterococcal and non-enterococcal endocarditis, diphtheria, anthrax, bacterial meningitis, Lyme disease, gonorrhea, syphilis, actinomycosis, botulism and others. The first generation penicillins are susceptible to inactivation by beta-lactamase, and resistance is relatively common. The usual doses of intravenous penicillin G are 300,000 to 4 million units every 6 to 8 hours. Benzathine penicillin G is given in a one time dose of 2.4 million units intramuscularly as therapy of primary or secondary syphilis, and as three weekly doses for syphilis of longer duration; it is also used as prophylaxis against rheumatic fever. Penicillin V is available in tablets of 250 and 500 mg and is usually given in doses of 250 to 500 mg every 6 to 8 hours for 7 to 20 days. It is also available as an oral solution. Side effects of penicillin G and V include nausea, diarrhea, gastrointestinal upset, headache, dizziness, rash and hypersensitivity reactions. Severe adverse events include anaphylaxis which can be severe and even fatal, angioedema, pseudomembranous colitis, C. difficile infection and Jarisch-Herxheimer reactions.
Can penicillin cause liver damage?
Rare instances of idiosyncratic liver injury have been reported in persons receiving the first generation penicillins. Many case reports predated availability of serologic testing for viral hepatitis and many described patients with multiple reasons for having liver disease (such as sepsis) and who were receiving other potentially hepatotoxic agents. Three distinct forms of liver injury can occur with the first generation penicillins: (1) transient, asymptomatic elevations in serum aminotransferase levels with prolonged high doses of parenteral penicillin, (2) minor liver injury associated with severe hypersensitivity reactions, and (3) idiosyncratic, delayed cholestatic hepatitis. These three forms of injury probably occur with all four generations of penicillin, some being more common with one form of penicillin than another.
Can penicillin cause cholestatic hepatitis?
Finally, isolated case reports have shown that the first generation penicillins can cause a delayed cholestatic hepatitis that probably represents idio syncratic hepatotoxicity. Symptoms of nausea, abdominal discomfort, jaundice and pruritus generally arise 1 to 4 weeks after starting therapy, and often a few days or weeks after completing a course. The serum enzyme pattern is usually cholestatic, but may be mixed or hepatocellular if tested soon after onset. Immunoallergic features are common, but autoantibody formation is rare. Most cases are mild-to-moderate in severity and resolve rapidly (Case 2). This delayed form of idiosyncratic cholestatic hepatitis is typical of many penicillins and cephalosporins, varying in frequency with the specific form. Idiosyncratic, cholestatic hepatitis is quite rare with the natural penicillins, more common with certain broad spectrum penicillins (cloxacillin, flucloxacillin) and is most common with amoxicillin with clavulanic acid.
