- AE: orthostatic hypotension
hydrochlorothiazide (Microzide)
- Class: thiazide and thiazide like diuretic
- MOA: inhibits distal convoluted tubule sodium and chloride resorption. Because most Na+ was reabsorbed before reaching the distal tubule, thiazides diuresis less than loop diuretics.

spironolactone (Aldactone)
1 DDI
- Class: potassium sparing diuretic, aldosterone receptor antagonist
- MOA: antagonizes aldosterone-specific mineralocorticoid receptors primarily in the distal convoluted tubule, decreasing Na and water reabsorption and increasing K retention
- AE: renal failure, severe hyperkalemia, arrhythmia
- DDI: potassium rich foods
digoxin (Lanoxin)
- Class: cardiac glycoside
- MOA: Inhibits sodium-potassium ATPase resulting in calcium ion release which causes a positive inotropic effect. Suppresses SA node and slows AV node conduction to lower ventricular rate.
