While broad spectrum antibiotics play an invaluable role in the treatment of bacterial infections, there are some drawbacks to their use, namely selection for and spread of resistance across multiple bacterial species, and the detrimental effect they can have upon the host microbiome.
What is an example of a broad spectrum antibiotic?
· A clear advantage to the use of broad-spectrum antibiotics is that there is less of a need (as compared with narrow-spectrum antibiotics) to identify the infecting pathogen with real certainty before commencing treatment.

What is the best antibiotic for MDR Gram negative bacteria?
Carbapenem antibiotics remain the last line of defense against many MDR-Gram negative bacilli. Doripenem is the newest carbapenem and may offer a potency advantage for select isolates of Pseudomonas aeruginosa. It is not useful for the treatment of carbapenemase-producing organisms.
What are the most common adverse effects of a syringe?
Headache, nausea, diarrhea, rash, and phlebitis were the most common adverse effects, occurring in at least 5% of patients. Cases of rare but serious adverse effects such as anaphylaxis, neutropenia, leukopenia, Stevens-Johnson syndrome, and toxic epidermal necrolysis are described in postmarketing reports.
How can antimicrobial stewardship help?
Antimicrobial stewardship programs can assist in reducing the emergence of MDROs by optimizing antimicrobial use and enhancing clinical outcomes. There are no available vaccines that target HAIs caused by MDROs, although this is an active area of investigation. Today’s top picks on the Haymarket Medical Network.
Is vancomycin a Gram positive drug?
Anti-gram-positive agents. Vancomycin is predominantly used for serious infection due to resistant Gram-positive infections, including MRSA. HAIs associated with VRE and S. aureus with increasing vancomycin MICs have prompted the need for alternative therapies. Therapeutic drug monitoring is often required.
Why is vancomycin used?
Vancomycin is predominantly used for serious infection due to resistant Gram-positive infections, including MRSA. HAIs associated with VRE and S. aureus with increasing vancomycin MICs have prompted the need for alternative therapies. Therapeutic drug monitoring is often required.
Is daptomycin a cyclic lipopeptide?
Prolonged use may be limited by toxicity. Daptomycin is a bactericidal cyclic lipopeptide with activity against resistant Gram-positive organisms, including MRSA and VRE. Although available only for IV administration, it is preferred for long-term use given its favorable toxicity profile in comparison to linezolid.
Can daptomycin be used for pneumonia?
Daptomycin should not be used for treatment of pneumonia due to its inactivation by pulmonary surfactant. Telavancin is a new lipoglycopeptide with activity against resistant Gram-positive organisms while ceftaroline is the first FDA-approved b-lactam with activity against MRSA.
Can broad spectrum antibiotics be used for multiple infections?
Narrow-spectrum#N#Narrow-spectrum antibiotics are not helpful in treating infections that are caused by multiple types of bacteria.#N#Broad-spectrum#N#Often, it is not just one type of bacteria that causes the infection. In such cases, broad-spectrum antibiotics would be recommended to treat such a ‘super’ infection.
What are some examples of narrow spectrum antibiotics?
Examples. The best example of a narrow-spectrum antibiotic is sodium fusidate, which is formulated to destroy staphylococcal strains of bacteria. Azithromycin, clarithromycin, clindamycin, erythromycin, and vancomycin are some of the medications that belong to this class of antibiotics.
What is broad spectrum antibiotic?
Broad spectrum antibiotics are formulated to destroy a large number of different types of bacteria. They are effective against a wide range of infections caused by a variety of bacteria. So, illnesses caused by both gram-negative and gram-positive bacteria can be effectively treated with these antibiotics.
What is the difference between broad spectrum and narrow spectrum?
The difference between narrow-spectrum and broad-spectrum lies in the range of bacteria that the antibiotic can act on . The latter class of antibiotics are better at treating different types of bacterial infections.
Why are antibiotics narrow spectrum?
Uses. Narrow-spectrum. One cannot rule out the possibility of bacteria becoming resistant to narrow-spectrum antibiotics. The reason for this is that these types of antibiotics target only a specific group of bacteria. Broad-spectrum. These are designed to attack a larger group of bacteria, so they are particularly useful in treating diseases ...
Why are antibiotics useful?
These are designed to attack a larger group of bacteria, so they are particularly useful in treating diseases caused by bacteria that are resistant to narrow-spectrum antibiotics.
Do narrow spectrum antibiotics work?
Narrow-spectrum#N#Narrow-spectrum antibiotics are not prescribed as frequently. Due to this fact, bacteria are found to be less resistant to this class of antibiotics.#N#Broad-spectrum#N#People put on these antibiotics are at an increased risk of becoming resistant to these drugs. Though they work against a range of bacterial attacks, the growing number of cases of bacteria surviving treatment with these antibiotics is worrying.
