Alpha blockers are a class of drugs commonly used in the management of various medical conditions, including hypertension and benign prostatic hyperplasia. These drugs work by blocking the alpha-1 receptors in the body, which relaxes the smooth muscles and dilates the blood vessels. There are several other synonyms that can be used to refer to alpha blockers, including alpha-adrenergic antagonists, alpha-antagonists, and alpha-receptor blockers. All these terms refer to the same group of drugs and are often used interchangeably in medical literature. Some of the commonly prescribed alpha blockers include doxazosin, prazosin, and terazosin, and they have proven to be effective in managing different medical conditions.
