Decrease in blood flow to the region can also decrease the outflow of deoxygenated blood from the region. This effect is used to prolong the action of local anaesthesia medication. For this vasoconstrictor medication like adrenaline is commonly added to local anaesthetic medication like lignocaine.<\/p>\n<h2><span style=\"color: #0000ff;\">Downside of vasoconstrictors<\/span><\/h2>\n<p>Vasoconstrictors often stimulate the heart and increase the heart rate.
