Which class of drugs is identified by the suffix '-micin'?

Antibacterial
Antiviral
Antifungal
Analgesic

The correct answer is: Antibacterial

The class of drugs identified by the suffix '-micin' refers to antibacterial agents, specifically a subset known as aminoglycoside antibiotics. These drugs are primarily used to treat serious bacterial infections, especially those caused by Gram-negative bacteria. Aminoglycosides, such as gentamicin, tobramycin, and amikacin, are characterized by their mechanism of action, which involves inhibiting bacterial protein synthesis, ultimately leading to cell death. Their efficacy is notable in severe infections, including those in hospital settings or infections that are resistant to other antibiotic classes. Understanding the suffix '-micin' helps healthcare professionals identify these potent antibiotics within a broader pharmacological context, ensuring correct usage and awareness of potential side effects, including nephrotoxicity and ototoxicity.
