|
2nd line tx of pulmonary HTN/right heart failure/CHF
Second to Sildenafil or CCB's |
|
Bradykinin MOA
|
at B1 receptor --> pospholipase --> NO, PG's, substance P --> long term vasodilation, cough, and pain
at B2 receptor --> phospholipase --> PG's, NO, & substance P --> short term vasodilation and pain --> SNS reflex |
|
What metabolizes Bradykinin?
|
ACE/Kininase II
|
|
Captopril

|
|
Losartan
|
ARB
|
|
Nitrate (nigroglycerin, Isosorbide kinitrate, and mononitrate) effect on vasculature and mOA
|
nitrate esters that vasodilate both venous and with a high enough dose, arteries (therefore reduce pre and after load --> decreases O2, incrases supply --> decreases vasospasm)
|
|
Nitrate effect on CNS
|
there will be a SNS reflex
|
|
Nitrate effect on coagulability?
|
platelet i
|
|
When is Nitropruside used?
|
MOA like that of Nitrates, except toxic with prolonged use (cyanide), therefore only use, IV, for acute HTN in those with CHF

|
When is Sildenafil used?
|
Pulmonary HTN (CHF) or ED
PDE5i |
|
What is the MOA of Sildenafil?
|
PDE5i therefore used for pulmonary HTN
|
|
What drug is a PDE5i?
|
Sildenafil for pulm HTN
|
|
When is Minoxidil used?
|
used for severe/refractory HNT (K channel therefore arterial only)
used with other drugs (BB and diuretic) |
|
what is the MOA of minoxidil?
|
K channel blocker therefore arterial only
extreme action/effect therefore only use in extreme HTN Hair growth |
|
What drug is a K channel blocker?
|
