What route is typically used for administering hydrochlorothiazide?

Hydrochlorothiazide is primarily administered orally, which is why this option is correct. This thiazide diuretic is commonly taken in the form of a tablet or capsule, making the oral route the most appropriate and effective way for patients to receive the medication. The absorption and bioavailability of hydrochlorothiazide when taken orally allows it to exert its diuretic effects effectively by promoting urine production and the excretion of sodium and water.

While diuretic agents can sometimes be delivered via other routes in certain clinical settings, for hydrochlorothiazide specifically, the oral route is the established and preferred method for patients. This is beneficial for outpatient management of conditions such as hypertension or edema. Other routes like intravenous, subcutaneous, and inhalation are generally not used for this medication, as they do not provide the same consistent therapeutic level or convenience for long-term use as the oral route does.
