  1. What are the Mechanisms for Na+ absorption throughout the Nephron?
    • PT- NaHCO3
    • LH- Na/K/2Cl Symport
    • DT-NaCl
    • CT- Na/K channel
  2. What is the location of the Strongest and most efficatious Diuretics?
    in the LH, becaues it has less compensation later on.
  3. What are the Inhibitors of Na+ K+2Cl Co-transport?

    What is the Efficacy?

    Ethacrynic acid

    - High eficacy
  4. What are the Inhibitors of Na-Cl Co-transport?

    What is the efficacy?
    Chlorothiazide, Chlorthalidone, Metolazone and Indapamide (thiazide like diuretic).

    -Medium Efficacy
  5. Diuretics that act in the PT,LH,DT cause some degree of compensation in the CT. What is the primary Toxicity of these diuretics?
    • -Hypokalcemia--> can cause Arrythmias
    • -Metabolic Alkalosos
  6. Carbonic anhydrase inhibitor diuretic
  7. Acetazolamide
    Does NOT cause Alkalosis
  8. Potassium sparing diuretics
    Where is its action?

    When is this used?

    Inhibitors of Na+ K+ 2Cl Co-transport a High ceiling loop diuretic.

    • -Thick ascending loop of Henle
    • -Mild alkalosis at high dose
    • -rapid increase in systemic venous capacitance and decrease left ventricular filling pressure

    pulmonary edema
  12. Furosemide
    What does it increase?
    What can be seen?
    What is a common toxicity seen in intravenous administration?
    • -Increases calcium excretion
    • -Hyperglycemia and hyperuricemia can be occasionally seen with loop diuretics.

    -Ototoxicity frequently
  13. What drug shouldnt be given with Furosemide?
    Aminoglycosides, because both cause ototoxicity.
