What are considered the ‘Big Three’ properties of an ideal drug? (Select all that apply)

Choice A reason: Patient preference is not a primary concern in food-drug interactions; physiological effects are. Grapefruit’s impact on metabolism is significant, so this is incorrect for the true statement.

Choice B reason: Foods can alter absorption and metabolism, but some also affect drug action (e.g., tyramine with MAOIs). This statement is incomplete, making it incorrect compared to grapefruit’s specific effect.

Choice C reason: Grapefruit inhibits CYP isoenzymes, altering drug metabolism and increasing drug levels. This is a well-documented interaction, making it the correct true statement about food-drug interactions.

Choice D reason: Not all medications are best absorbed with food; some require empty stomachs. Grapefruit’s metabolic interaction is more accurate, so this is incorrect for the true statement.

Choice A reason: Hydrochlorothiazide can treat diabetes insipidus by reducing urine output via sodium reabsorption, but this is a secondary use. Its primary role is in hypertension management, as it lowers blood pressure by decreasing blood volume, making this choice less accurate.

Choice B reason: Hydrochlorothiazide, a thiazide diuretic, is primarily used for hypertension by promoting sodium and water excretion, reducing blood volume and vascular resistance. It’s a first-line treatment per guidelines, effectively lowering blood pressure, making this the correct choice for its primary indication.

Choice C reason: Hydrochlorothiazide treats edema in heart failure or renal disease by increasing diuresis, but this is a secondary indication. Its primary use is hypertension, where it reduces blood pressure more consistently across patients, making this choice less accurate than hypertension.

Choice D reason: Hydrochlorothiazide doesn’t protect against postmenopausal osteoporosis. While thiazides reduce urinary calcium loss, they’re not indicated for osteoporosis prevention, unlike bisphosphonates. Their primary role is hypertension management, making this choice incorrect for the drug’s main therapeutic use.
