Which drug class kills or inhibits the growth of fungi?

• A. Anticancer
• B. Antibacterial
• C. Antianemic
• D. Antifungal

Answer: (D)

Drugs that kill or stop the growth of fungi are antifungals. This class is defined by its activity against fungal organisms, exploiting targets that are more specific to fungi than to humans. For example, many antifungals interfere with ergosterol in the fungal cell membrane or with components of the fungal cell wall, weakening or rupturing fungal cells. Specific mechanisms include blocking ergosterol synthesis, binding ergosterol to disrupt membranes, or inhibiting glucan synthesis to weaken the cell wall. This focused action on fungi distinguishes antifungals from other drug classes. The other options target different problems: anticancer drugs act on cancer cells, antibacterial drugs act on bacteria, and agents labeled antianemic address anemia. None of these are defined by killing or inhibiting fungal growth, which is why the antifungal class is the correct choice.
