Which drug class replaces elements lost due to dehydration or illness?

• A. Anti-impotence
• B. Antiprotozoal
• C. Antispasmodic
• D. Electrolyte replacement

Answer: (D)

When a person loses fluids from dehydration or illness, they also lose essential electrolytes like sodium, potassium, and chloride. Replacing these elements is the purpose of electrolyte replacement therapy. These agents come as oral solutions or IV fluids (such as normal saline or lactated Ringer’s) that supply the key ions needed to restore proper fluid balance, osmolality, and acid-base status. Some solutions also include glucose to help intestinal absorption, which makes oral rehydration especially effective after GI losses. This approach directly targets restoring electrolyte levels, rather than treating a condition like erectile dysfunction, a protozoal infection, or muscle spasms, which is why other drug classes listed don’t fit this purpose.
