Which of the following is not a common initial treatment option for hypertension?

In the management of hypertension, thiazide diuretics, ACE inhibitors, and beta blockers are commonly utilized as first-line treatment options. Thiazide diuretics are particularly effective and recommended for initial therapy in many patients due to their ability to lower blood pressure while providing added benefits for cardiovascular health.

ACE inhibitors are also frequently prescribed as a first option, especially for patients with certain comorbidities, such as diabetes or chronic kidney disease, because they help protect renal function and reduce cardiovascular risks.

Beta blockers, while traditionally not the first choice for hypertension, can be used in specific patient populations, especially those with associated conditions such as heart failure or coronary artery disease.

In contrast, loop diuretics are typically not used as first-line agents for the management of hypertension unless patients have specific conditions, such as heart failure or renal impairment, that necessitate their use. Loop diuretics are more potent and often used for fluid management rather than as primary antihypertensive agents. Therefore, among the listed options, loop diuretics are least commonly prescribed initially for hypertension, making this the correct choice.
