It may also help with some symptoms associated with the common cold [ 4 ] and may also be used for sedating people who are agitated or anxious, an effect that has led to ...
If healthy blood pressure is no higher than 120/80, but blood pressure is not viewed as a problem until it hits at least 140/90, consider all the damage that is being done before any intervention ...
There are more women than men with hypertension, [19] and, although men develop hypertension earlier in life, [20] hypertension in women is less well controlled. [21] [22] The consequences of high blood pressure in women are a major public health problem and hypertension is a more important contributory factor in heart attacks in women than men ...
In July 1975, the J. B. Williams Co. began marketing Sominex 2. [37] On November 24, 1975, Attorney General Evelle J. Younger filed suit on behalf of the State of California against Williams Co., stating that the product did not warn against use by pregnant or nursing women or persons with asthma or COPD, nor did it notify consumers that it should not be used in conjunction with alcohol.

“This low circulating blood volume causes the release of the hormone vasopressin and when in high enough concentrations, vasopressin constricts blood vessels and causes higher blood pressure ...
Antihypertensive therapy seeks to prevent the complications of high blood pressure, such as stroke, heart failure, kidney failure and myocardial infarction. Evidence suggests that a reduction of blood pressure by 5 mmHg can decrease the risk of stroke by 34% and of ischaemic heart disease by 21%.
For most people, recommendations are to reduce blood pressure to less than or equal to somewhere between 140/90 mmHg and 160/100 mmHg. [2] In general, for people with elevated blood pressure, attempting to achieve lower levels of blood pressure than the recommended 140/90 mmHg will create more harm than benefits, [3] in particular for older people.

The impairment of cerebral blood flow that underlies hypertensive encephalopathy is still controversial. Normally, cerebral blood flow is maintained by an autoregulation mechanism that dilates arterioles in response to blood pressure decreases and constricts arterioles in response to blood pressure increases. This autoregulation falters when ...
