What is the difference between a broad spectrum antibiotic and a narrow-spectrum antibiotic Why does the difference matter in a clinical context?

Antibiotics are classified as broad or narrow-spectrum based on the range of bacterial species susceptible to their action. Broad-spectrum antibiotics act against both Gram-positive and Gram-negative bacteria, while narrow-spectrum antibiotics are only effective against either Gram-positive or Gram-negative bacteria.

What is meant by narrow-spectrum antibiotics?

A narrow-spectrum antibiotic is an antibiotic that is only able to kill or inhibit limited species of bacteria. Examples of narrow-spectrum antibiotics include vancomycin, fidaxomicin and sarecycline.

Which is the broad-spectrum antibiotics?

A broad-spectrum antibiotic acts against both Gram-positive and Gram-negative bacteria, in contrast to a narrow-spectrum antibiotic, which is effective against specific families of bacteria. An example of a commonly used broad-spectrum antibiotic is ampicillin.

What are the dangers of using broad-spectrum antibiotics vs narrow-spectrum antibiotics?

Many disease-causing organisms are bacteria; however, not all bacteria cause disease. Some bacteria are necessary for essential functions like digestion. Broad-spectrum antibiotics – Antibiotics that target a wide range of bacteria. They are often more toxic and cause more side effects than narrow-spectrum antibiotics.

What are examples of narrow-spectrum antibiotics?

Examples of narrow-spectrum antibiotics are the older penicillins (penG), the macrolides and vancomycin. Examples of broad-spectrum antibiotics are the aminoglycosides, the 2nd and 3rd generation cephalosporins, the quinolones and some synthetic penicillins.

When are narrow-spectrum antibiotics used?

Narrow spectrum antibiotics are used for the specific infection when the causative organism is known and will not kill as many of the normal microorganisms in the body as the broad spectrum antibiotics. So, It has less ability to cause superinfection.

Which of the following is narrow-spectrum antibiotics?

Benzylpenicillin (Penicillin G) is a narrow spectrum antibiotic used for the treatment of susceptible bacterial infections. It is a natural antibiotic of penicillin, given intravenously or intramuscularly because of slow oral absorption.

Which is more effective broad spectrum antibiotics or narrow spectrum antibiotics?

Broad-spectrum antibiotics are not more effective than narrow-spectrum antibiotics in treating pediatric ARTIs. Narrow-spectrum antibiotics were associated with a lower risk of side effects.

When to prescribe broad spectrum antibiotics to children?

When bacteria cause an ear, nose, or throat infection in children, a clinician may prescribe narrow- or broad-spectrum antibiotics. A PCORI-funded research study found a greater risk of side effects with broad-spectrum antibiotics, with no difference in symptom resolution between the two types.

Do you need a blood test for a narrow spectrum antibiotic?

A blood test is usually ordered before prescribing a narrow-spectrum antibiotic. After the test points toward a specific type of bacteria, the doctor would prescribe an antibiotic that is specifically formulated for that particular infection. A major advantage here is that a blood test to find out the causative agent is not necessary.

How are bacteriostatic antibiotics different from bactericidal antibiotics?

In contrast to bactericidal antibiotics, bacteriostatic antibiotics stop bacteria from growing. This word is also easy to remember: the suffix ‘static’ means staying stable. The bacteria don’t die, but they can’t grow or replicate either. So, how do bacteriostatic antibiotics help clear up an infection, if they don’t actually kill bacteria?

What is a wide spectrum antibiotic?

A broad-spectrum antibiotic is an antibiotic that acts on the two major bacterial groups, gram-positive and gram-negative, or any antibiotic that acts against a wide range of disease-causing bacteria. These medications are used when a bacterial infection is suspected but the group of bacteria is unknown…

What is a narrow spectrum drug?

– Narrow spectrum are drugs that are effective against just gram positive bacteria, just gram negative bacteria or only a few bacteria.
