Document Summary

Dobultamine - activates the b1 receptors to increase the rate and force of contractions of the heart. The baroreceptors sense an increase in the blood pressure, and communicates with the. Cns and increases the activation of the psns, decrease the sns to create vasodilation. The vasodilation is because of less activation of alpha 1 receptors. Phenylephrine - activates the a1 receptors in the blood vessels causing vasoconstriction. The baroreceptors detect the change in blood pressure and activates the cns and increases the. Psns while decreasing the sns and then decreases the heart rate. Used in nasal sprays to relieve congestion by activating a1 receptors and reducing the blood. Clonidine - opiate drug withdrawal, pain, diarrhea, glaucoma, hypertension, adhd. For a glaucoma it acts as an a receptor agonist which decrease the secretion of aqueous humour and decrease the intra ocular pressure as a result. For diarrhea, we have a2 receptors on ach releasing neutrons in the gi tract.
