What are the properties of antimicrobial agents?
Abstract. To realize their full potential for effective therapy in critically ill patients, antimicrobial agents must share three essential characteristics, namely in vivo as well as in vitro effectiveness, lack of toxicity, and reasonable cost.
What are the 3 types of antimicrobials?
Examples: Antibiotics, antiseptics, and disinfectants. Let us look at some antimicrobial agents and their types with examples.
What are the four main types of antimicrobial substances?
The main groups are: agents that inhibit cell wall synthesis, depolarize the cell membrane, inhibit protein synthesis, inhibit nuclei acid synthesis, and inhibit metabolic pathways in bacteria.
What are the classification of antimicrobial?
Antimicrobial agents are classified into several categories, i.e. inhibitors for bacterial cell wall such as beta-lactam drugs, fosfomycin, and vancomycin; inhibitors for protein biosynthesis such as tetracyclibnes, macrolides, aminoglycoside antibiotics; inhibitors for DNA synthesis such as 4-quinolones; inhibitors …
What are the five main classes of antimicrobial drugs?
Antibacterials are used to treat bacterial infections. Antibiotics are classified generally as beta-lactams, macrolides, quinolones, tetracyclines or aminoglycosides. Their classification within these categories depends on their antimicrobial spectra, pharmacodynamics, and chemical composition.

What are the five major antimicrobial drug groups?
There are five main antibacterial drug targets in bacteria: cell-wall synthesis, DNA gyrase, metabolic enzymes, DNA-directed RNA polymerase and protein synthesis. The figure shows the antimicrobial agents that are directed against each of these targets.
What are the 7 main types of antibiotics?
In this portal, antibiotics are classified into one of the following classes: penicillins, fluoroquinolones, cephalosporins, macrolides, beta-lactams with increased activity (e.g. amoxicillin-clavulanate), tetracyclines, trimethoprim-sulfamethoxazole, lincosamides (e.g. clindamycin), urinary anti-infectives, and other …
What is the most commonly used antimicrobial?
Gentamicin and tobramycin are used most commonly and are the primary agents used to treat infections caused by gram-negative rods, most notably Pseudomonas species. Although most antibiotics that inhibit protein synthesis are bacteriostatic, the aminoglycosides are frequently bactericidal.
What are antimicrobials used for?
Antimicrobials – including antibiotics, antivirals, antifungals and antiparasitics – are medicines used to prevent and treat infections in humans, animals and plants.
What are the 3 most common antibiotics?
The main types of antibiotics include: Penicillins – for example, phenoxymethylpenicillin, flucloxacillin and amoxicillin. Cephalosporins – for example, cefaclor, cefadroxil and cefalexin. Tetracyclines – for example, tetracycline, doxycycline and lymecycline.

Why is antimicrobial important?
Antimicrobials are an extremely valuable resource across the spectrum of modern medicine. Their development has been associated with dramatic reductions in communicable disease mortality and has facilitated technological advances in cancer therapy, transplantation, and surgery.
