- heparin, enoxaparin, warfarin, fondaparinux, rivaroxaban, apixaban, dabigatran
8
Q
beta-1 adrenergic receptor antagonists
A
- antihypertensive; cardioselective beta blocker
- compete with norepinephrine and epinephrine at beta-1 adrenergic receptor sites in heart resulting in decreased sympathetic activity → decreased heart rate, decreased cardiac contractility
- indications: angina, hypertension, MI/CAD (core measure), heart failure
- contraindications: pulmonary edema, uncompensated HF, cardiogenic shock, bradycardia, heart block
- SE/ADRs: bradycardia, hypotension, fatigue, erectile dysfunction, hypoglycemic unawareness

9
Q
beta-1 and beta-2 adrenergic receptor antagonists
A
- antihypertensive; non-cardioselective beta blocker
- compete with epinephrine and norepinephrine at receptor sites in heart, bronchioles, and vascular smooth muscle resulting in decreased sympathetic activity → decreased HR, decreased contractility, some vasoconstriction, and bronchoconstriction
- indications: angina, hypertension, MI/CAD (core measure), heart failure
- contraindications: asthma, acute bronchospasm, lung issues, uncompensated HF, pulmonary edema, cardiogenic shock, bradycardia, bradyarrhythmias, heart block

10
Q
calcium channel blockers
A
- antihypertensive
- blocks entry of calcium into cells of vascular smooth muscle and myocardium → dilation of coronary arteries and inhibition of vasospasm; diltiazem and verapamil also slow conduction through AV node → slowed HR
- indications: angina, hypertension, coronary artery vasospasm, dysrhythmias (verapamil and diltiazem), cerebral vasospasm (nimodipine; has relatively selective effect on cerebral blood vessels)

Q
