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.

How do you administer IV penicillin?

How do you administer penicillin G?

Penicillin G procaine (aqueous) is for intramuscular injection only. Administer by DEEP INTRAMUSCULAR INJECTION in the upper, outer quadrant of the buttock (dorsogluteal) or the ventrogluteal site. In neonates, infants and small children, the midlateral aspect of the thigh may be preferable.

Which antibiotics can be given IM?

Can penicillin be given in the deltoid muscle?

The deltoid site is most commonly used for immunizations. However, only up to 1 mL of any medication may be administrated in this muscle. The gluteal site is commonly used to administer antibiotics, or any medication, when the volume exceeds 2 mL but is less than 3 mL for an adult.

Can amoxicillin be given IM?

Intramuscular administration should only be considered when the intravenous route is not possible or less appropriate for the patient.

Why is benzylpenicillin not given orally?

Oral penicillin G is no longer used because it is subject to degradation in the presence of stomach acid. Penicillin V and amoxicillin have chemical structures that enhance their stability in acidic environments and result in improved oral absorption (bioavailability).

Are IV antibiotics stronger than oral?
