Benzylpenicillin

Benzylpenicillin, also known as penicillin G, is an antibiotic used to treat a number of bacterial infections. Pronounced as ben-zil-pen-i-sil-in, it is derived from the Penicillium fungi.

Etymology

The term "Benzylpenicillin" is derived from the chemical structure of the drug, which includes a benzyl group and a penicillin core. The "penicillin" part of the name comes from the Penicillium fungi from which it was first isolated.

Usage

Benzylpenicillin is used to treat a variety of infections caused by Gram-positive bacteria, including Streptococcus pneumoniae, Group A streptococcus, and Staphylococcus aureus. It is also effective against some forms of Gram-negative bacteria, such as Neisseria meningitidis.

Administration

Benzylpenicillin is typically administered via intravenous or intramuscular injection. It is not typically used orally because it is unstable in the stomach acid.
