Blood pressure is altered by either the diameter of the blood vessels, particularly the arteries or cardiac output. Both the heart and blood vessels are controlled by a section of the brain called the medulla oblongata. In order to lower blood pressure the medication must target this area. When the pressure rises due to excessive cardiac output the best way to lower it is by sending a drug containing histine, a protien to the cardio-inhibatory centre of the medulla oblongata which will decrease the cardiac output.
When the cause of hypertension is vasoconstriction, the target is the vasomotor centre. Impulses from the baroreceptors in artery walls stimulate this centre to send impulses along the parasympathetic nerves telling the vessels to dilate to allow blood flow. Therefore any drug with a high content of carbohydrates should increase the conc. of the blood and consequently hte pressure causing stimulation of the baroreceptors and hence the notaworthy dilation of the arteries, decreasing the pressure.
