What type of drugs are used to treat gram-negative organisms?

The use of drugs that end with "mycin," specifically aminoglycosides and certain macrolides, is often effective against gram-negative organisms. These drugs function by inhibiting protein synthesis in bacteria, which is crucial for the growth and replication of the organisms. Notably, aminoglycosides like gentamicin and tobramycin are particularly potent against a variety of gram-negative pathogens, including Pseudomonas aeruginosa, which is known for its resistance and relevance in clinical settings.

The choice that includes "mycin" encompasses antibiotic categories that are tailored for fighting gram-negative infections. While other classes of antibiotics can also address gram-negative bacteria, those ending in "mycin" are well-known for their specific efficacy against resistant strains.

Other options may represent valid classes of antibiotics but do not exclusively or predominantly target gram-negative organisms. For example, "cillin"-based medications (beta-lactams) are often more effective against gram-positive bacteria, while those ending in "cidal" may refer to a mechanism rather than a specific class of bacteria. Drugs that end with "azole" typically refer to antifungal agents rather than antibiotics, hence they are not targeted towards bacterial infections at all.
