MedKoo CAT#: 317511

CAS#: 58-93-5

Description: Hydrochlorothiazide is a thiazide diuretic often used to treat high blood pressure and swelling due to fluid build up. It reduces the reabsorption of electrolytes from the renal tubules. This results in increased excretion of water and electrolytes, including sodium, potassium, chloride, and magnesium.
