Which of the following represents a common class of antibiotics?

The class of antibiotics represented by the suffix "-mycin" includes a variety of antimicrobial agents that are commonly used to treat bacterial infections. This suffix is derived from the names of multiple antibiotics that share similar structures and mechanisms of action, such as erythromycin, azithromycin, and clarithromycin. These antibiotics work by inhibiting protein synthesis in bacteria, making them effective against a broad range of bacterial pathogens.

In contrast, the other suffixes mentioned refer to different classes of drugs. For instance, "-conazole" generally denotes antifungal agents, "-azepam" refers to benzodiazepines which are used for anxiety and sedation, and "-olol" is used for beta-blockers, which are frequently prescribed for hypertension and heart conditions. This distinction highlights the varied therapeutic classes of drugs and reinforces the understanding of antibiotic pharmacology.
