Hypertensive Medications Flashcards
ACE inhibitors: Prototype
captopril [Capoten]
lisinopril
enalopril
ramipril
ACE inhibitors: EPA
Block enzymes that convert angiotensin 1 to angiotensin 2, decreasing vasoconstriction and aldosterone as an effect. Results in retention of K+ and vasodilation
ACE inhibitors: Therapeutic Use
Treatemnt of HTN and Heart failure
ACE inhibitors: ADRs
Orthostatic hypotension, Dry non-productive cough, Hyperkalemia, Angioedema, Taste distortions, Rash
ACE inhibitors: Contraindications
Pregnancy [teratogenic]
Avoid NSAIDs
Liver disease
ACE inhibitors: Intervention
Avoid salt substitutes
Moniter K+ due to hyperkalemia potential
Angiotensin II Receptor Blockers [ARBs]: Prototype
losartan [Cozaar]
Angiotensin II Receptor Blockers [ARBs]: EPA
Blocks vasoconstricting and aldosterone-secreting effects of angiotensin II. Increased renal bloodflow
Angiotensin II Receptor Blockers [ARBs]: Therapeutic Use
Treatment of HTN, Stroke prevention [losartan only], Diabetic nephropathy, Heart failure.
Angiotensin II Receptor Blockers [ARBs]: ADR’s
Angioedema, dizziness, Hypotension, Headache, and Insomnia
Angiotensin II Receptor Blockers [ARBs]: Contraindications
Teratogenic, NSAIDs increase the risk of renal complications.
Aldosterone Antagonists: Prototype
eplereone [Inspra]
Aldosterone Antagonists: EPA
Blocks aldosterone receptors thereby blocking the effects of aldosterone.
Aldosterone Antagonists: Therapeutic Use
HTN, and symptoms of heart failure following a myocardial infarction
Aldosterone Antagonists: ADR
Hyperkalemia
Aldosterone Antagonists: Contraindications
Avoid medications that raise potassium levels like ACE inhibitors. Avoid if breastfeeding. Caution in children. NSAIDs may decrease effects. Do not take if serum K levels are greater than or equal to 5 mEq/L
Avoid if the client is taking lithium because of the effects lithium has on the kidneys. Lithium blocks aldosterone as do Aldosterone Antagonists causing a multiplicative effect on the ADR.
Direct Renin Inhibitors: Prototype
aliskiren [Tekturna]
Direct Renin Inhibitors: EPA:
Binds with renin which inhibits the activation of angiotensin I
Direct Renin Inhibitors: Therapeutic Use
HTN
Direct Renin Inhibitors: ADRs
Diarrhea, Dyspepsia [Indigestion], Abdominal pain, Hyperkalemia [very rare], Angioedema, Dry non-productive cough [uncommon]
Direct Renin Inhibitors: Contraindications
Pregnancy and lactation, hyperkaleimia, younger than 18, ACE and ARBS, increases blood levels of atorvastatin
Calcium Channel Blockers: Protypes
nifedipine [Adalat / Procardia]
amlodipine [Norvasc]
verapamil [Calan]
diltiazem [Cardizem]
Calcium Channel Blockers: EPA
Block calcium channels in smooth muscles and peripheral arteries
Calcium Channel Blockers: Therapeutic Use
HTN, Stable angina
