Betaxolol also shows greater affinity for beta 1 receptors than metoprolol. In addition to its effect on the heart, betaxolol reduces the pressure within the eye (intraocular pressure). This effect is thought to be caused by reducing the production of the liquid (which is called the aqueous humor) within the eye. The precise mechanism of this ...
Antihypertensive agents comprise multiple classes of compounds that are intended to manage hypertension (high blood pressure). Antihypertensive therapy aims to maintain a blood pressure goal of <140/90 mmHg in all patients, as well as to prevent the progression or recurrence of cardiovascular diseases (CVD) in hypertensive patients with established CVD.

Class of antihypertensives that work by causing relaxation of blood vessels as well as a decrease in blood volume, which leads to lower blood pressure and decreased oxygen demand from the heart. [1] Benazepril; Captopril; Enalapril; Fosinopril; Lisinopril; Moexipril; Perindopril; Quinapril; Ramipril; Trandolapril
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.
The combination of beta blockers and antihypertensive drugs will work on different mechanism to lower blood pressure. [17] For example, the co-administration of beta-1 blocker atenolol and ACE inhibitor lisinopril could produce a 50% larger reduction in blood pressure than using either drug alone. [18]

Age and multi-morbidity can affect the choice of medication, the target blood pressure and even whether to treat or not. [61] Anxiety may be improved with the use of beta blockers. Asthmatics have been reported to have worsening symptoms when using beta blockers. Beta blockers can trigger or worsen psoriasis, psoriatic arthritis, and rheumatoid ...
Metoprolol, sold under the brand name Lopressor among others, is a medication used to treat angina, high blood pressure and a number of conditions involving an abnormally fast heart rate. [4] It is also used to prevent further heart problems after myocardial infarction and to prevent headaches in those with migraines . [ 4 ]
