Vasodilation works to decrease vascular resistance and blood pressure through relaxation of smooth muscle cells in the tunica media layer of large arteries and smaller arterioles. [17] When vasodilation causes systolic blood pressure to fall below 90 mmHg, circulatory shock is observed. [11]
Nitric oxide is considered an anti anginal drug: It causes vasodilation, which can help with ischemic pain, known as angina, by decreasing the cardiac workload. By dilating (expanding) the arteries, nitric oxide drugs lower arterial pressure and left ventricular filling pressure. [ 91 ]
Beets. Wong also suggests beets to lower blood pressure, explaining that they are rich in inorganic nitrate, which converts to nitric oxide. As a vasodilator, nitric oxide widens and relaxes blood ...
[6] [7] [8] VIP stimulates contractility in the heart, causes vasodilation, increases glycogenolysis, lowers arterial blood pressure and relaxes the smooth muscle of trachea, stomach and gallbladder. In humans, the vasoactive intestinal peptide is encoded by the VIP gene. [9] VIP has a half-life (t ½) in the blood of about two minutes. [10]

Bradykinin (BK) (from Greek brady-'slow' + -kinin, kīn(eîn) 'to move') is a peptide that promotes inflammation.It causes arterioles to dilate (enlarge) via the release of prostacyclin, nitric oxide, and endothelium-derived hyperpolarizing factor and makes veins constrict, via prostaglandin F2, thereby leading to leakage into capillary beds, due to the increased pressure in the capillaries.
Cause vasodilation in the systemic arterial circulation. [1] Cause vasoconstriction of the liver sinusoidal and pulmonary venous systems. [19] Increased risk of tumor adhesion on endothelial cells. [1] Decrease platelet aggregation responses. [1] Increase axon growth in neurons. [13]
Consumption of foods that are themselves vasodilators, such as alcoholic beverages or cinnamon, can increase the probability of an angioedema episode in susceptible patients. If the episode occurs at all after the consumption of these foods, its onset may be delayed overnight or by some hours, making the correlation with their consumption ...
