Diuretics Flashcards
➢ General site of action is the nephron structure in the kidney.
➢ Increases urine formation and output resulting in net loss of H2O from the body and decreased BP.
DIURETICS
A potent diuretic that results in substantial fluid loss because it Inhibits Na+ and Cl reabsorption in the loop of Henle and so H20.
Dilated blood vessels & treats edema associated with CHF & hepatic/renal disease
LOOP DIURETICS
Example of Thiazide
- Hydrodiuril
- Zaroxolyn
It inhibits the sodium – chloride transporter in the distal tubule. It affects the excretion of Na+, Cl-, K+, and H2O without altering pH.
For the treatment of edema
THIAZIDE
Examples of Loop Diuretics
*Furosemide
*Torsemide
*Bumetanide
➢ Antagonized the actions of aldosterone at the distal segment of the distal tubule
➢ Causes more sodium and water to pass into the collecting duct and be excreted in urine.
POTASSIUM SPARING DIURETICS
Potassium Sparing Diuretic Prototype
ALDACTONE
➢Inhibits the action of the enzyme carbonic anhydrase.
➢ Important for the excretion of hydrogen.
➢ It slows down the movement of hydrogen ions which leads to greater amount of sodium and bicarbonate lost in the urine
CARBONIC ANHYDRASE INHIBITORS
It is most often used for the treatment of Glaucoma and is used as adjunct to other diuretics when more
intense diuresis is needed.
CARBONIC ANHYDRASE INHIBITORS
This type of diuretic exerts their therapeutic effect by pulling water into the renal tubule without loss of sodium.
OSMOTIC DIURESIS
One and only example of osmotic diuresis
MANNITOL
