What type of drugs inhibit bacterial growth and rely on the host's defenses to kill the bacteria?

Bacteriostatic drugs are specifically designed to inhibit bacterial growth rather than directly killing the bacteria. They work by interfering with various bacterial processes, such as protein synthesis or DNA replication, effectively halting the growth and reproduction of the bacteria. This allows the host's immune system to take over and eliminate the existing bacteria.

For instance, common examples of bacteriostatic agents include tetracyclines and sulfonamides. By preventing the bacteria from multiplying, these drugs give the immune system the opportunity to target and destroy the bacteria that are present.

On the other hand, bactericidal drugs actively kill bacteria, which provides a different mechanism of action. Bacteriolytic refers to a subset of bactericidal agents that cause the bacteria to lyse or break apart, leading to their death. Broad-spectrum refers to the activity against a wide variety of bacteria, but it does not indicate whether the drugs are bacteriostatic or bactericidal.
