Alpha-blockers are a type of medication that works by relaxing the muscle in the prostate gland and the bladder neck, making it easier to urinate. Some common synonyms for the word "alpha-blocker" include alpha-adrenergic antagonist, alpha-adrenergic blocker, alpha adrenoceptor antagonist, alpha receptor blocker, alpha-1 adrenergic receptor blocker, and alpha1-blocker. These different terms refer to the same class of medications that are used to treat conditions such as urinary retention, benign prostatic hyperplasia, high blood pressure, and Raynaud's disease. Examples of alpha-blockers include doxazosin, tamsulosin, prazosin, and terazosin. It's important to speak with a healthcare provider before starting any medication to ensure it's safe and effective for your specific medical condition.
