Loop diuretics are pharmacological agents that primarily inhibit the Na-K-Cl cotransporter located on the luminal membrane of cells along the thick ascending limb of the loop of Henle. [4] They are often used for the treatment of hypertension and edema secondary to congestive heart failure , liver cirrhosis , or chronic kidney disease .
The antihypertensive actions of some diuretics (thiazides and loop diuretics in particular) are independent of their diuretic effect. [ 1 ] [ 2 ] That is, the reduction in blood pressure is not due to decreased blood volume resulting from increased urine production , but occurs through other mechanisms and at lower doses than that required to ...
Thiazide diuretics (e.g. hydrochlorothiazide, chlorthalidone, chlorthiazide) – may be useful for mild CHF, but typically used in severe CHF in combination with loop diuretics, resulting in a synergistic effect. Potassium-sparing diuretics (e.g. amiloride) – used first-line use to correct hypokalaemia.
Cardiovascular agents are drugs that affect the rate and intensity of cardiac contraction, blood vessel diameters, blood volume, blood clotting and blood cholesterol levels. [1] They are indicated to treat diseases related to the heart or the vascular system (blood vessels), such as hypertension , hyperlipidemia , coagulation disorders , heart ...

Note that, for cardiac function curve, "central venous pressure" is the independent variable and "systemic flow" is the dependent variable; for vascular function curve, the opposite is true. Venous return curves showing the normal curve when the mean systemic filling pressure (Psf) is 7 mm Hg and the effect of altering the Psf to 3.5, 7, or 14 ...
Prostaglandin E 2 (PGE 2), also known as dinoprostone, is a naturally occurring prostaglandin with oxytocic properties that is used as a medication. [2] [3] [4] Dinoprostone is used in labor induction, bleeding after delivery, termination of pregnancy, and in newborn babies to keep the ductus arteriosus open.
Hyponatremia (low blood sodium) occurred in 4.1% of subjects randomized to chlortalidone in the Systolic Hypertension in the Elderly Trial, compared to 1.3% of control subjects. [36] The risk of hyponatremia varies from 5 per 100,000 person-years for those younger than 40 years of age to 730 per 100,000 person-years in those older than 80 years ...
