Final answer:
The type of drug that causes increased urination is a diuretic. Loop diuretics work on the kidney's loop of Henle to inhibit reabsorption of ions, leading to increased urine production.
Step-by-step explanation:
The type of drug that causes increased urination is a diuretic. Diuretics, especially loop diuretics, are often used to treat conditions such as hypertension. They work by inhibiting the reabsorption of sodium (Na+) and chloride (Cl-) ions in the ascending limb of the loop of Henle within the nephron of the kidney. This mechanism leads to an increase in urine volume, which is why diuretics can cause increased urination as a side effect.
