Diurético
Where the word appears among blood pressure medicines
MedlinePlus names diuretics among the most commonly used blood pressure medicines, alongside angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs), beta blockers, and calcium channel blockers. It explains that these medicines work in different ways to lower blood pressure. Diuretics, it says, are often used with other high blood pressure medicines, sometimes in one combined pill, and often two or more medicines work better than one. MedlinePlus adds that while taking the medicines it is still important to keep up with healthy lifestyle changes.
What it means
A diuretic is a type of drug that causes the kidneys to make more urine, according to the National Cancer Institute (NCI) dictionary. Diuretics help the body get rid of extra fluid and salt, and they are used to treat high blood pressure, edema (extra fluid in the tissues), and other conditions. The same entry says there are many different types of diuretics and that they are sometimes called water pills. MedlinePlus, in its page on blood pressure medicines, says diuretics remove extra water and sodium (salt) from the body, which lowers the amount of fluid in the blood. This page explains the word only; decisions about any medicine belong with the prescribing health care provider.

Diurético is the headword of the National Cancer Institute's Spanish dictionary, which defines it as a type of medicine that makes the kidneys produce more urine. The Real Academia Española dictionary enters the word as diurético, ca, a medical adjective for something that has the power to increase the excretion of urine, and adds that it is also used as a masculine noun. Spanish therefore has both the noun el diurético (plural los diuréticos) and the adjective, which agrees with its noun. The written accent falls on the é.
Where the English entry says diuretics are sometimes called water pills, the National Cancer Institute's Spanish entry says píldoras contra la retención de líquidos. MedlinePlus en español uses the plural los diuréticos in its page on blood pressure medicines (Medicinas para la presión arterial), where it says they remove excess agua y sodio (sal). Nearby words in the dictionary entry are orina (urine), riñones (kidneys), presión arterial alta (high blood pressure) and edema, glossed there as extra fluid in the tissues.
