Different b lactam antibiotics differ in their side chain. There are several types of B-lactam antibiotics which are potentially important. Beta-lactam antibiotics include penicillins, cephalosporins and related compounds.

This includes penicillin derivatives ( penams ), cephalosporins ( cephems ), monobactams , carbapenems [1] and carbacephems . [2] Carbapenems and penems.

Some antimicrobials (eg, cefazolin and cloxacillin) are naturally resistant to certain beta-lactamases. The activity of the beta-lactams: amoxicillin, ampicillin, piperacillin, and ticarcillin, can be restored and widened by combining them with a beta-lactamase inhibitor. Clavulanic acid, sulbactam, and tazobactam are all beta-lactamase inhibitors.

As a group, these drugs are active against many gram-positive, gram-negative and anaerobic organisms. β-Lactams represent perhaps the most important class of antibiotics yet discovered.

-Lactams are classified according to their core ring structures. There are many types of antibiotics available, including topical antibiotics, natural ones and prescription antibiotics. Topical and natural antibiotics may be available over the counter, but the list of most common antibiotics that need to Here are some common ailments which you can cure with OTC medicines — so you can prevent potential antibiotic resistance and harmful side effects.

beta-lactamases, particularly in Gram-negative pathogens, are a major determinant of this resistance, although alterations in the beta-lactam targets, the penicillin-binding proteins (PBPs), are also important, especially in Gram-positive pathogens.

Doctors widely prescribe these drugs for patients with a range of infections. β-Lactam antibiotics act by binding to penicillin-binding proteins (PBPs), thus inhibiting bacterial cell wall synthesis.

Numerous classes of antibiotics fall into this family, including drugs effective against Gram positive and Gram negative bacterial organisms. Doctors widely prescribe these drugs for patients with a range of infections. β-Lactam antibiotics are currently the most used class of antibacterial agents in the infectious disease armamentarium. As shown in Figure 1, β-lactams account for 65% of all prescriptions for injectable antibiotics in the United States. What are carbapenems • Carbapenems are a class of beta-lactam antibiotics with a broad spectrum of antibacterial activity.
