Cardiology Pharm (Antihypertensive Agents) Flashcards
What are the Antihypertensive Agents? (4)
Diuretics: see Renal Pharm
RAA system: ACE inhibitors; ARB (Ang II receptor blockers
Sympathoplegics
Vasodilators
What are the RAA system effectors? (2)
ACE inhibitors
Losartan
What are the ACE inhibitors? (3)
Captopril
Enalapril
Fosinopril
What is the mechanism of Action ACE inhibitors?
Inhibits the conversion of Ang I to Ang II -> decreases Ang II and prevents vasoconstriction from Ang II
What are the indications for ACE inhibitors? (4)
Hypertension
CHF
post MI
vasodilator
What are the adverse effects of ACE inhibitors? (4)
Hyperkalemia, cough, angioedema,
Contraindicated in Pregnancy (fetal Renal malformations)
What is the mechanism of Action Losartan?
ARB (Ang II receptor blockers) => prevents vasoconstriction from Ang II
What are the indications for Losartan?
Hypertension
What are the adverse effects of Losartan? (2)
Fetal renal toxicity
Hyperkalemia
What are the Sympathoplegics? (13)
Metoprolol, Atenolol, Acebutolol, Esmolol, Propranolol, Timolol, Carvedilol Prazosin Clonidine Methyldopa Hexamethonium Reserpine Guanethidine
What is the mechanism of action of Metoprolol, Atenolol, Acebutolol, Esmolol, Propranolol,
Timolol, Carvedilol?
B1-Blocker: Metoprolol, Atenolol, Acebutolol, Esmolol
B1 and B2 Blocker: Propranolol,
Timolol
Alpha and B-Blocker: Carvedilol
What are the indications for B-Blockers? (4)
Hypertension
Angina
MI
Antiarrhythmic
What are the adverse effects of B-Blockers? (7)
Impotence Asthma Bradycardia Av block Heart failure Sedation Sleep alterations
What is the mechanism of action of Prazosin? (2)
aplha 1-Blocker -> vasodilation -> decreases TPR
What are the indications for Prazosin? (2)
Pheochromocytoma
Hypertension
What are the adverse effects of Prazosin?
Orthostatic Hypotension
What is the mechanism of action of Clonidine?
alpha 2 agonist => decreases peripheral resistance
What are the indications for Clonidine? (4)
Hypertension
Smoking
Cocaine
Heroin withdrawal
