Carbapenems | Bacterial Targets, Mechanism of Action, Side Effects

This video lesson covers carbapenem antibiotics, highlighting their characteristics, bacterial targets, and broad spectrum of activity. It explains their mechanism of action, which involves inhibiting bacterial cell wall synthesis, and discusses the growing issue of resistance. The video also outlines the adverse reactions associated with carbapenems and introduces ertapenem, a newer carbapenem with a narrower spectrum. The lesson emphasizes the use of carbapenems in serious infections, particularly those involving resistant organisms.

What is a key characteristic of ertapenem compared to other carbapenems?

• Broader spectrum

• Narrower spectrum

• More effective against Pseudomonas

• Used orally

What is the primary use of carbapenems in clinical settings?

• Treating viral infections

• Preventing infections in healthy individuals

• Treating mild infections

• Treating severe infections by resistant organisms

How do carbapenems inhibit bacterial growth?

• By disrupting DNA replication

• By inhibiting protein synthesis

• By blocking cell wall synthesis
