Doxazosin: A Selective Alpha-1 Blocker
Doxazosin is a selective alpha-1 blocker, meaning it primarily targets alpha-1 receptors in the body. This action leads to relaxation of smooth muscle, particularly in blood vessels and the prostate.
Uses of Doxazosin
High Blood Pressure: Doxazosin can help lower blood pressure by relaxing blood vessels, allowing blood to flow more easily.
Benign Prostatic Hyperplasia (BPH): It is commonly used to treat BPH, a condition characterized by an enlarged prostate. By relaxing the muscles of the prostate and bladder neck, doxazosin can improve urinary flow and reduce symptoms such as frequent urination, difficulty starting or stopping urination, and weak urine stream.
