The narrowing of blood vessels leads to an increase in peripheral resistance, thereby elevating blood pressure. While vasoconstriction is a normal and essential regulatory mechanism for maintaining blood pressure and redistributing blood flow during various physiological processes, its dysregulation can contribute to pathological conditions.
Phenylephrine, sold under the brand names Neosynephrine and Sudafed PE among others, is a medication used as a decongestant for uncomplicated nasal congestion in the form of a nasal spray or oral tablet, [5] to dilate the pupil, to increase blood pressure given intravenously in cases of low blood pressure, and to relieve hemorrhoids as a suppository.
The researchers discovered that replacing a less active behavior, like sitting or standing, with five minutes of exercise could lower systolic blood pressure (the force of blood flow when blood is ...
To put this into perspective, some research shows that reducing your systolic blood pressure (top blood pressure reading) by 5 mmHg may lower your risk of cardiovascular events by 10%! The Bottom Line
A 2019 study also found that disrupted sleep was more likely to cause spikes in blood pressure during the evening, as well as the day after. Chronic stress can also lead to an increased risk.
Phenylpropanolamine was first synthesized around 1910 and its effects on blood pressure were first characterized around 1930. [ 21 ] [ 11 ] It was introduced for medical use by the 1930s. [ 23 ] [ 11 ] The medication was withdrawn from many markets starting in 2000 following findings that it was associated with increased risk of hemorrhagic stroke.
