Beta blockers are used to treat acute cardiovascular toxicity (e.g. in overdose) caused by sympathomimetics, for instance caused by amphetamine, methamphetamine, cocaine, ephedrine, and other drugs. [38] Combined α 1 and beta blockers like labetalol and carvedilol may be more favorable for such purposes due to the possibility of "unopposed α ...

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. [2]
Medications used include: diuretic agents, vasodilator agents, positive inotropes, ACE inhibitors, beta blockers, and aldosterone antagonists (e.g., spironolactone). Some medications which increase heart function, such as the positive inotrope milrinone, lead to increased death, and are contraindicated. [9] [10]
These drugs are often first-line treatment for the target diseases and are effective in tackling the symptoms. An example of the target disease is ischemic heart disease. Some examples of commonly prescribed drugs for this disease are beta-blockers, calcium-channel blockers and nitrates.
Beta-blockers. Beta-blockers are stopped or decreased in people with acutely decompensated heart failure and a low blood pressure. However, continuation of beta-blockers may be appropriate if the blood pressure is adequate. [16] Inotropic agents. Inotropes are indicated if low blood pressure ( SBP < 90 mmHg ) is present.
Carvedilol is a nonselective beta blocker and alpha-1 blocker. [5] How it improves outcomes is not entirely clear but may involve dilation of blood vessels. [5] Carvedilol was patented in 1978 and approved for medical use in the United States in 1995. [5] [8] It is on the World Health Organization's List of Essential Medicines. [9]
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]
