Why are alpha-blockers not used in hypertension?
4 While this risk is real, it is small, and the main reason that alpha blockers are not used as a first-choice drug is because, unlike other high blood pressure medicines, they have not been shown to reduce the risk of stroke and heart attack.
Do alpha-adrenergic blockers treat hypertension?
Alpha blockers are also called alpha-adrenergic blocking agents, alpha-adrenergic antagonists, adrenergic blocking agents and alpha-blocking agents. Examples of alpha blockers used to treat high blood pressure include: Doxazosin (Cardura) Prazosin (Minipress)
Which alpha1 blocker is effective for hypertension?
Prazosin, doxazosin, and terazosin are nonspecific α-1 blockers and are used to treat hypertension; they can cause (postural) hypotension. α-1 blockers are the most effective medical pharmacologic therapy for BPH-associated lower urinary tract symptoms.
Does tamsulosin lower blood pressure?
Tamsulosin is an alpha-adrenergic blocker, which is also sometimes called an alpha-blocker. It works by blocking the effects of norepinephrine on alpha-1 receptors (attachment sites). This helps lower blood pressure and relaxes smooth muscles in the prostate, helping to improve urine flow.
Who should not take alpha-blockers?
Kidney disease, circulatory diseases or respiratory infections. Non-selective alpha-blockers may not be an option if you have one or more of these conditions.
Do alpha-blockers have side effects?
The most common side-effects are slight drowsiness, headaches and dizziness. More rarely they can cause sexual problems. Alpha-blockers are also associated with an increased risk of falling and of breaking a bone (fracture) when they are first started.
What are the most common side effects of alpha-blockers?
Does tamsulosin affect the heart?
Taking too much tamsulosin can lead to a decrease in your blood pressure and an increase in your heart rate.
Which is best treatment for hypertension?
The two classes of medication are both recommended as “first-line” treatments for high blood pressure: angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs). ACE inhibitors have been around longer and studied more extensively, so doctors prescribe them more often.
Do alpha-blockers affect the brain?
Alpha blockers are not expected to cause cognitive impairment. Although 5-ARIs have strong pharmacokinetic profiles that may suggest cognitive impairment, the clinical studies have shown that they are less prone to cause dementia. However, they may cause affective disorders such as depression.
Do alpha-blockers affect heart rate?
Abstract. Objective: Although alpha-blockers are effective in lowering blood pressure, they may increase heart rate, an unwanted effect that could negatively affect outcome.
What is an alternative to doxazosin?
Doctors also prescribe four other drugs in this class to treat the symptoms of BPH: alfuzosin (Uroxatral) doxazosin (Cardura) silodosin (Rapaflo)
What is the cure of hypertension?
Try the Dietary Approaches to Stop Hypertension (DASH) diet, which emphasizes fruits, vegetables, whole grains, poultry, fish and low-fat dairy foods. Get plenty of potassium, which can help prevent and control high blood pressure. Eat less saturated fat and trans fat. Decrease the salt in your diet.

Who should not take doxazosin?
talk to your doctor about the risks and benefits of taking doxazosin if you are 65 years of age or older. Older adults should not usually take doxazosin to treat high blood pressure, because it is not as safe as other medications that can be used to treat the same condition.
Which alpha blocker is safest?
Silodosin
- Silodosin is a highly sensitive alpha-1A receptor antagonist with little or no cardiovascular side-effects.
- In particular, silodosin has been shown to be more effective than tamulosin in relieving nocturia, incomplete bladder emptying and frequency.
