A narrow-spectrum antibiotic is an antibiotic that is only able to kill or inhibit limited species of bacteria. [1] Examples of narrow-spectrum antibiotics include fidaxomicin and sarecycline . Advantages
The following is a list of antibiotics. ... May be more narrow-spectrum than vancomycin, resulting in less bowel microbiota alteration. [9] Nausea (11%), vomiting ...
Narrow-spectrum antibiotics have low propensity to induce bacterial resistance and are less likely to disrupt the microbiome (normal microflora). [3] On the other hand, indiscriminate use of broad-spectrum antibiotics may not only induce the development of bacterial resistance and promote the emergency of multidrug-resistant organisms, but also cause off-target effects due to dysbiosis.
This is a list of common β-lactam antibiotics—both administered drugs and those not in clinical use—organized by structural class. Antibiotics are listed alphabetically within their class or subclass by their nonproprietary name. If an antibiotic is a combination drug, both ingredients will be listed.
Monobactam antibiotics exhibit no IgE cross-reactivity reactions with penicillin but have shown some cross reactivity with cephalosporins, most notably ceftazidime, which contains an identical side chain as aztreonam. [8] Monobactams can trigger seizures in patients with history of seizures, although the risk is lower than with penicillins.
Sarecycline is a narrow-spectrum antibiotic. [56] [57] Omadacycline: 16+ hours (long) (formerly known as PTK-0796 [58]) received FDA approval on October 2, 2018, for treatment of community-acquired pneumonia [59] and acute skin and skin structure infections. [60]
These antibiotics are effective principally against Gram-positive cocci. First-generation examples exhibit a narrow spectrum of action and are bactericidal only against the enterococci. Some tissues are not penetrated very well by glycopeptides, and they do not penetrate into the cerebrospinal fluid.
The first in a new class of narrow-spectrum macrocyclic antibiotics, fidaxomicin, has been approved for the treatment of C. difficile colitis. [162] New cephalosporin-lactamase inhibitor combinations also approved include ceftazidime-avibactam and ceftolozane-avibactam for complicated urinary tract infection and intra-abdominal infection.
