Why is vancomycin used as a last resort?

Vancomycin has long been considered a drug of last resort, due to its efficiency in treating multiple drug-resistant infectious agents and the requirement for intravenous administration. Recently, resistance to even vancomycin has been shown in some strains of S. aureus (sometimes referred to as vancomycin resistant S.

Is vancomycin a last resort antibiotic?

Vancomycin, long considered a "drug of last resort," kills by preventing bacteria from building cell walls. It binds to wall-building protein fragments called peptides, in particular those that end with two copies of the amino acid D-alanine (D-ala).

Why are antibiotics a last resort?

A last-resort antibiotic is used to treat infections with bacteria that are resistant against the common antibiotics or, in cases of severe infections, where an effect must be ensured.

Why is vancomycin so strong?

Conclusions. The mechanism of action of vancomycin can be explained by remembering that bacteria need a strong cell wall to protect it. This wall is made of peptidoglycan, a mix of proteins and sugars. Gram-positive bacteria have a thick cell wall that is exposed to the fluid in the environment around the cell.

Can bacteria become resistant to vancomycin?

Antibiotic resistance occurs when the germs no longer respond to the antibiotics designed to kill them. If these germs develop resistance to vancomycin, an antibiotic that is used to treat some drug-resistant infections, they become vancomycin-resistant enterococci (VRE).

Why is vancomycin not used routinely for bacterial infections?

As with other antimicrobials, prolonged or inappropriate treatment with vancomycin can lead to bacterial resistance, such as vancomycin-resistant enterococci (VRE). [15] Providers need to be aware of increased antimicrobial resistance patterns and practice appropriate antimicrobial stewardship.
