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.

Guidelines on the choice of agents and how best to step up treatment for various subgroups in hypertension (high blood pressure) have changed over time and differ between countries. A Comparison of International Guidelines on Goal Blood Pressure and Initial Therapy for Adults With Hypertension (adapted from JNC 8 guidelines [ 1 ] )
Propranolol can cross the blood-brain barrier and exert effects in the central nervous system in addition to its peripheral activity. [ 15 ] In addition to blockade of adrenergic receptors , propranolol has very weak inhibitory effects on the norepinephrine transporter and/or weakly stimulates norepinephrine release (i.e., the concentration of ...
Beta blockers must not be used in the treatment of selective alpha-adrenergic agonist overdose. The blockade of only beta receptors increases blood pressure, reduces coronary blood flow, left ventricular function, and cardiac output and tissue perfusion by means of leaving the alpha-adrenergic system stimulation unopposed.
Chlorthalidone is the thiazide drug that is most strongly supported by the evidence as providing a mortality benefit; in the ALLHAT study, a chlorthalidone dose of 12.5 mg was used, with titration up to 25 mg for those subjects who did not achieve blood pressure control at 12.5 mg. Chlorthalidone has repeatedly been found to have a stronger ...
Blood pressure (BP) is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in a brachial artery, where it is most commonly measured.
Conjugated estrogens/medroxyprogesterone acetate (CEs/MPA), sold under the brand names Prempro and Premphase, is a combination product of conjugated equine estrogens (Premarin), an estrogen collected from horse urine, and medroxyprogesterone acetate (Provera), a progestogen, which is used in menopausal hormone therapy for the treatment of menopausal symptoms.
An antihypotensive, also known as vasopressor, is an agent that raises blood pressure by constricting blood vessels, thereby increasing systemic vascular resistance. This is different from inotropes which increase the force of cardiac contraction. Some substances do both (e.g. dopamine, dobutamine).
