Discovered in the late 1940s, polymyxin B is a polypeptide antibiotic of the polymyxin class, a group of powerful agents used primarily against severe, multidrug-resistant Gram-negative bacterial infections.

Less than half of antimicrobial agents are bacteriostatic, meaning they inhibit bacterial growth rather than directly killing the microorganisms. Understanding **what are the examples of bacteriostatic agents?** is crucial for comprehending how different antibiotics function and when they are most effectively used to treat various infections.

Introduced in 1972, amoxicillin is one of the most widely prescribed antibiotics worldwide. A critical aspect of understanding this drug is knowing what type of antibiotic is amoxicillin, which belongs to the penicillin family of medications and, more specifically, a sub-class called aminopenicillins. This classification explains its broad spectrum of activity against many bacterial infections, from earaches to pneumonia.

In 2022, U.S. healthcare professionals prescribed 236.4 million antibiotic courses [1.9.1]. Understanding their classes is vital, so is gentamicin a beta-lactam antibiotic? The definitive answer is no; they belong to entirely different pharmacological classes with distinct mechanisms [1.2.1, 1.3.3].

According to research, bacteriostatic antibiotics are often as effective as bactericidal drugs for many common infections in patients with healthy immune systems. This comprehensive guide explores the specific classes of **which antibiotics are bacteriostatic**, their mechanisms, and clinical uses.

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.

Globally, azithromycin is one of the most frequently prescribed antibiotics [1.2.2]. This prevalence often leads to a common question in pharmacology: **Is azithromycin an aminoglycoside?** The definitive answer is no; it belongs to the macrolide class of antibiotics [1.2.1].

The discovery of penicillin, the first β-lactam antibiotic, in 1928 marked a turning point in modern medicine. This class of drugs, defined by a unique β-lactam ring, includes the penicillins, cephalosporins, carbapenems, and monobactams. The presence of a beta lactam ring in the molecular structure is the key characteristic that unifies these diverse and widely used antibacterial agents.
