    • *imidazoline antagonist!
    • Dichloroisoproterenol: β1 and β2 antagonist
    • Tx: Hypertension
    • ADEs: hypotension, bradycardia, fatigue, drowsiness
    • Pronethalol: β1 and β2 antagonist
    • Tx: Hypertension
    • ADEs: hypotension, bradycardia, fatigue, drowsiness
    • Labetalol: β1 and β2 AND α1 antagonist
    • Tx: Hypertension
    • ADEs: hypotension, bradycardia, fatigue, drowsiness
    • Propranolol: β1 and β2 antagonist (ortho-meta)
    • Tx: Hypertension, glaucoma, migraine, hyperthyroidism, angina pectoris, myocardial infarction
    • ADEs: hypotension, bradycardia, fatigue, drowsiness

    • Tx: Hypertension
    • ADEs: hypotension, bradycardia, fatigue, drowsiness
    • *Cleared renally, thus not dependent on individual metabolism. Therefore easier to dose.

    • Tx: Hypertension
    • ADEs: hypotension, bradycardia, fatigue, drowsiness
    • Nebivolol: β1 antagonist (newest)
    • Tx: Hypertension
    • ADEs: hypotension? It is the most β1-specific, so perhaps it doesn't have as many side effects?
