Why might alpha1 blockers be used in the treatment of BPH?

  1. They increase muscle mass

  2. They reduce bladder obstruction

  3. They decrease prostate size

  4. They increase urinary flow rates

The correct answer is: They increase urinary flow rates

Alpha1 blockers, also known as alpha-1 adrenergic receptor blockers, are used to relax the muscles in the prostate and bladder neck. This helps to improve urinary flow rates and decrease symptoms of BPH. Options A, B, and C are incorrect because alpha1 blockers do not have a direct effect on muscle mass, bladder obstruction, or prostate size. These options may be related to other treatments for BPH, but not specifically for alpha1 blockers. Therefore, option D is the most appropriate choice.
