    -What are its 2 functions?
    -Classification: therapeutic? pharmacologic?
    -What are the two areas for non-adrenaline use?
    • 1) stimulates alpha & beta receptors.
    • 2) acts on cardiac & respiratory cells.

    • Class:
    • (therapeutic): bronchodilater, antiasthmatic, vasopressor
    • (pharmacologic): adrenergic.

    Non-adrenaline: 1) asthma 2) cardiac stimulation.
