38
What is the mechanism of action for Spironolactone?

39
What diuretic will could cause, as adverse affect, gynecomastia and menstrual irregularities?
Spironolactone (steroid side effects are seen)
40
What will occur when NSAID's and Spironolactone are interacted?
reduced BP lowering
41
what is the mechanism of action for clonidine?
Stimulation of central and spinal alpha 2 adrenergic receptors (presynaptic and post junctional) Note: It is a Central Acting Alpha Agonist
42
what is a serious side effect seen with clonidine?
Angioedema
43
what happens if you take ophthalmic beta-blockers and decongestants with clonidine?
antagonistic effect | **beta blockers should be BP lowering but they enhance sympathomimetic activity at alpha1 receptors
44
What is the mechanism of action for hydralazine?
Directly dilates peripheral vessels via hyperpolarization of vascular smooth muscle which thus inhibits Ca++ influx (depolarization)
45
what are the side effects for hydralazine?
headaches and Lupus erythematosus
46
What is a important drug interaction with hydralazine?
NSAID's (antagonistic = these raise BP)
47
What is the mechanism of action for Hydrocholorthiazide?
Inhibits reabsorption of NaCl at distal convoluted tubule
48
What is the mechanism of action for beta blockers?
Antagonism of B1 receptor reducing systolic BP and CO. Suppression of Renin activity
49
What Anti-hypertensive drug has a side effect of depression and short term memory loss?
Beta-Blockers (Meopholol, Propranolol and Atenolol)
50
What is the mechanism of action for Furosemide?
