Discovered by Alexander Fleming in 1928, penicillin was the first antibiotic and is considered one of the greatest advances in medicine. In its wake, countless lives were saved from infectious diseases. So, **which class of antibiotic is penicillin**? It is a beta-lactam antibiotic, a major drug class that also includes cephalosporins, carbapenems, and monobactams.

Both penicillins and cephalosporins are beta-lactam antibiotics that inhibit bacterial cell wall synthesis. However, key structural differences in their core rings and side chains explain **what makes cephalosporins different from penicillins**, leading to variations in their antimicrobial spectrum and resistance profiles.

Beta-lactam antibiotics comprise roughly half of the global antibiotic market, a testament to their widespread use and efficacy against a broad range of bacterial infections. To understand the diverse applications and appropriate usage of these drugs, it is essential to know **what are the names of beta lactam antibiotics**, which are categorized into several major classes based on their unique chemical structures.

As one of the first cephalosporin antibiotics to be marketed in the 1960s, cephalothin (Keflin) was a pioneering treatment for a variety of bacterial infections. Though less commonly used today due to the availability of newer agents, understanding what does cephalothin treat remains relevant, particularly in specific clinical contexts like surgical prophylaxis. This parenteral, first-generation antibiotic targets susceptible Gram-positive and some Gram-negative bacteria by disrupting their cell wall synthesis.

Over 70% of all hospital-administered antibiotics belong to the beta-lactam class, which includes penicillin. The simple answer to **which antibiotic does not interfere with protein synthesis** is penicillin, as its mechanism of action targets the bacterial cell wall instead of the ribosome.

First introduced in 1959, methicillin was a revolutionary semi-synthetic penicillin created to combat infections from penicillinase-producing bacteria, like *Staphylococcus aureus*. However, this vital drug was never manufactured for oral use because it is rapidly and extensively destroyed by gastric acid, making it ineffective if swallowed.

Constituting approximately 65% of the total antibiotics market, beta-lactam antibiotics are a cornerstone of modern medicine [1.7.2]. This large class of drugs is defined by a core chemical feature, but you may wonder, **what antibiotics have a beta-lactam ring structure?**

Ureidopenicillins are a class of penicillins, with piperacillin being a notable example, known for their broad-spectrum activity, particularly against *Pseudomonas aeruginosa*. This guide addresses the question: What drugs are ureidopenicillins? and explores their pharmacology and clinical significance.

Over 90% of ampicillin resistance in *E. coli* is due to the production of TEM-1 beta-lactamase. Understanding **how does beta-lactamase work** is crucial to developing strategies against the growing threat of antimicrobial resistance.

First isolated in 1928, the discovery of penicillin marked the beginning of the modern antibiotic era and revealed the potential of a core chemical structure known as the beta-lactam ring. This unique chemical feature is the namesake of a vast and critically important class of antibiotics known as beta-lactam antibiotics. These medications remain a cornerstone of infectious disease treatment due to their effectiveness against a wide range of bacterial pathogens.
